Union of Concerned Scientists Global Warming

Among the many attacks in President Trump’s Day 1 Executive Order on “unleashing” American (fossil) energy, is a directive to EPA administrator Zeldin to reevaluate the agency’s bedrock 2009 scientific determination of the harms caused by heat-trapping emissions and submit recommendations within 30 days (i.e. this week). The ‘Endangerment Finding’ establishes that heat-trapping emissions harm people and the environment, and it forms a core legal basis for the agency’s subsequent actions to set standards to limit global warming pollution from vehicles and power plants, as well as methane pollution from oil and gas operations.

It’s no surprise that this anti-science, pro-fossil fuel administration wants to go after the Endangerment Finding. Of course, an honest assessment of the latest climate science will show that since 2009 the evidence has become even more compelling and dire. Climate change, driven by rising heat-trapping emissions, is already causing significant harm to people’s health and well-being and to vital ecosystems. Those harms will worsen rapidly as global warming emissions, primarily from burning fossil fuels, increase.

This blatant attempt to do an end-run around scientific evidence deserves to fail.

What is the Endangerment Finding?

Back in 2007, the Supreme Court reached a landmark judgment in Massachusetts et al. v. Environmental Protection Agency et al. establishing that heat-trapping emissions (or greenhouse gas emissions) are air pollutants covered by the Clean Air Act. The court further mandated that, under the Clean Air Act, the EPA must set protective standards for global warming pollutants if the agency found them to be harmful to human health and welfare.

The 2007 case was brought by petitioners (which included several state attorney generals and NGOs, including the Union of Concerned Scientists) in the context of greenhouse gas emissions from new motor vehicles.

The EPA subsequently undertook an extensive process, including hearings and a public comment period, and concluded that a vast body of scientific evidence showed that heat-trapping pollutants do indeed harm public health and welfare and that motor vehicles contribute to that pollution.

In 2009, the agency issued the Endangerment and Cause or Contribute Findings for Greenhouse Gases, summarized below:

• Endangerment Finding: The Administrator finds that the current and projected concentrations of the six key well-mixed greenhouse gases—carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6)—in the atmosphere threaten the public health and welfare of current and future generations.
• Cause or Contribute Finding: The Administrator finds that the combined emissions of these well-mixed greenhouse gases from new motor vehicles and new motor vehicle engines contribute to the greenhouse gas pollution that threatens public health and welfare.

The findings have subsequently been extended to other major sources of heat-trapping emissions, including power plants and oil and gas operations, and have been upheld in court.

For more on the legal and political twists and turns in the history of the Endangerment Finding, please check out this blogpost: Endangered Science: Why Global Warming Emissions Are Covered by the Clean Air Act.

What is Zeldin being directed to do?

President Trump’s Day 1 executive order directs the EPA administrator to work with other relevant agencies to submit recommendations, within 30 days, to the director of the OMB on the “legality and continuing applicability” of the agency’s Endangerment and Cause or Contribute Findings for Greenhouse Gases under the Clean Air Act.

Opponents of climate action have long understood the power of the Endangerment Finding and tried unsuccessfully to dismantle it during the first Trump administration. Project 2025 also includes a call to “Establish a system, with an appropriate deadline, to update the 2009 endangerment finding.”

With a new more dangerous Trump administration, thoroughly corrupted by fossil fuel interests—and with the architect of Project 2025, Russell Vought, now confirmed as OMB Director—this time the risk to the Endangerment Finding is definitely greater. Gutting the Endangerment Finding would completely undermine EPA’s ability to regulate greenhouse gas emissions and put a stop to all of EPA’s regulations to limit global warming pollution, a gift to the fossil fuel industry.

But getting rid of the Endangerment Finding is not going to be easy and is by no means a foregone conclusion, as even Lee Zeldin knows. It would require such a brazen effort to lie about climate science evidence that it’s hard to imagine courts going along with that even if the EPA were to take that unwise route.

The latest climate science is clear and alarming

There’s no question that this is a bad faith effort to try to find ways to undercut EPA’s responsibility and authority to regulate heat-trapping emissions under the Clean Air Act. The fact remains that any science-based update to the Endangerment Finding would conclusively demonstrate that the actual harms and projected risks from climate change have only grown grimmer since the 2009 endangerment finding was issued.

As heat-trapping emissions, primarily from burning fossil fuels, continue to rise, global average temperatures too continue their relentless climb with 2024 once again the hottest year on record. Extreme climate-related disasters—including heatwaves, storms, droughts, wildfires and flooding—are worsening, taking a fearsome toll on people, the economy and ecosystems. Accelerating sea level rise, ocean acidification and loss of major ice sheets also continue apace, with profound consequences for the planet.

If Lee Zeldin is looking for a recent authoritative assessment of the science, he should turn to the 2023 Fifth US National Climate Assessment, produced under the direction of the US Global Change Research Program (USGCRP). The Global Change Research Act of 1990 mandates that the USGCRP—which collaborates across 15 federal agencies—deliver a report to Congress and the President at least every four years.

Here’s the headline from the NCA5:

The effects of human-caused climate change are already far-reaching and worsening across every region of the United States. Rapidly reducing greenhouse gas emissions can limit future warming and associated increases in many risks. Across the country, efforts to adapt to climate change and reduce emissions have expanded since 2018, and US emissions have fallen since peaking in 2007. However, without deeper cuts in global net greenhouse gas emissions and accelerated adaptation efforts, severe climate risks to the United States will continue to grow.

Another valuable source is the IPCC sixth assessment report, which reflects the work of thousands of scientists around the world—including many from the United States—in assessing the latest climate science, impacts, and opportunities to cut heat-trapping emissions and adapt to climate change.

The National Academy of Sciences would also be a good source of information. Here, for example, is a handy booklet on the evidence for and causes of climate change.

NOAA and NASA, premier federal science agencies, also closely monitor and track global climate change and its impacts. (And hopefully will continue to do so—although recent attacks on NOAA, foreshadowed in the Project 2025 manifesto, do not bode well.)

An anti-science pro-fossil fuel administration

Barely a month into the term of this second Trump administration, it’s clear that the President and his cabinet are hell-bent on doing everything they can to boost fossil fuels and shred climate and clean energy policies, catering to deep-pocketed fossil fuel interests.

They clearly intend to use every means at their disposal (lawful or not) to roll back regulations to help address global warming pollution. Those actions will be rightfully challenged in court, and it takes time to undo regulations in a legal way. However, any delay in implementing strong standards is harmful when the climate crisis is so acute. If the Trump administration succeeds in weakening or stopping EPA’s efforts to cut heat-trapping emissions, that will just leave people bearing the costs while fossil fuel polluters rake in profits.

Revisiting the endangerment and cause or contribute findings is just one more backdoor way to try to advance that harmful agenda. This directive shouldn’t fool anyone. It’s not a genuine effort to engage with scientific facts and listen to climate scientists. After all, the President has called climate change a hoax and many of his cabinet are climate science deniers.

The question for Lee Zeldin is whether he will just pander to that destructive agenda, or will he actually defend the mission of the agency he leads, which is to protect public health and the environment. He has already overseen a series of harmful actions at the EPA—including firing staff, cutting budgets, gutting its environmental justice work, and illegally freezing already-allocated funds for clean energy. So, I doubt we can count on a courageous defense of the endangerment finding from him.

Regardless of how Zeldin responds to President Trump’s directive, this administration cannot hide the reality of climate change. Undoing the Endangerment Finding is such an extremist anti-science endeavor, it is hard to imagine how it could succeed.

But we live in a country today where many previously unimaginable things are happening.

What is your morning routine? Wake up, maybe make coffee, tea, or other morning beverage or meal, check the weather. It is something most people do in the US—office workers, outdoor workers, farmers, fishermen, stay-at-home folks. No matter what one’s life is like, most of us are going to go outside, and most of us check the weather. This is how we, at least partially, assess how our day will go, what we’re going to wear, what activities we will be able to perform, how easy or dreary the commute will be, etc.

This is true for days with uneventful weather, but when extreme weather is in the forecast for the next few days or weeks, weather information becomes critical—even life-saving. Your morning newscasters or social media feeds typically give you “stay cool” tips in advance of a heat wave, or a hurricane warning for your coastal city may show you maps or list areas under mandatory evacuation order due to projected dangerous storm surge.  

But the reliance on that straightforward, taken-for-granted information may be imperiled. President Trump and unelected individuals designated by him are taking aim at scientists and illegally taking over infrastructure responsible for creating and issuing weather conditions and alerts—the National Oceanic and Atmospheric Administration (NOAA). The blueprint for many of the Trump administration’s actions, Project 2025, calls for dismantling and privatizing some of its essential services.  

Is having extreme weather information critical? Absolutely. Do we know what happened in the days before modern weather information systems were available to warn the public about extreme weather? We sure do. The Great Blizzard of 1888, for example, dropped as much as 58 inches of snow and “paralyzed the East Coast from the Chesapeake Bay to Maine to the Atlantic provinces of Canada.” Transportation via cars, trains, and boats was severely impacted, more than 400 people died, and melting snow after the storm severely flooded areas of the US Northeast. Having advance information about the location and magnitude of an extreme weather event is an essential component of strategies to stay safe, from households to first responders to businesses, to government at all levels.  

The prospect of dismantling the systems and jobs that make this information available is alarming on many fronts. The impacts could be so far-reaching that it is hard to understand why such a move is even being considered. Below are just a few things that will be impacted if the Trump administration follows through with the plans laid out in Project 2025 for dismantling NOAA. 

Extreme weather alerts and forecasts

Without NOAA’s freely-available data for all who currently use it to create daily and multi-day forecasts, everyday people will find themselves at a loss about preparing for weather. With extreme weather becoming more extreme due to human-caused climate change, it is essential that communities know what is coming in order to prepare adequately.  

Emergency response agencies, business owners, outdoor workers, farmers, fishermen, parents, caretakers, and everyday folks, all need to know what is coming so they can adjust their activities accordingly. How is your kids’ school principal supposed to know when it’s going to be too hot for children to play outside so they can plan to keep them indoors during a heatwave? What happens when a winter storm demands that roads are salted in anticipation of snowy and icy conditions—but transportation authorities can’t access information about when and how much ice, sleet, or snow will accumulate? How is a coastal community supposed to know what level of storm to prepare for or what areas to issue evacuation orders for? 

Hurricane forecasts

Due to climate change, hurricanes are more destructive: they’re stronger, they drop more rain, they hang around in one place for longer to do more damage from flooding and rain, and they intensify more rapidly, sometimes with horrifying speed.

To counter these impacts, NOAA’s National Hurricane Center provides data that saves lives and allows for preparedness at the local, regional and federal levels. Evacuations, shelters, infrastructure protections all depend on knowing with certainty the likelihood that a hurricane will make landfall. And NOAA’s forecasts and storm-tracking ability is getting better.

In 2022, NOAA assessed its forecasts and storm-tracking ability and found that since 2000, it had reduced its average 72-hour storm tracking error by 57%, while its error rate in predicting storm intensity had dropped by 40%. All these improvements would not be possible without proper funding and science, and without these improvements, forecasts would not be as confident as they are now, helping prevent loss of life and property across the United States. These forecasts were invaluable during the 2024 hurricane season, when NOAA’s accurate and early storm tracks for Hurricane Helene and Hurricane Milton prompted early evacuation orders and preparedness that saved lives and property.  

Rain, fire, drought

In addition to data for weather forecasts, the National Weather Service (a division of NOAA) provides data for daily wildfire, precipitation and drought outlooks for the entire United States. It also provides other severe weather outlooks and an overview of winter and tropical maritime conditions. The latter identifies current and expected activity in the Atlantic Ocean related to the formation of tropical storms and hurricanes. 

Fisheries

The information created by NOAA’s scientists goes beyond weather and the US borders, as it is used domestically and internationally to protect and project fisheries’ yields and determine legal catch sizes. This is done through the National Marine Fisheries Service (NMFS), whose goals are to maintain and protect ocean ecosystems for both natural ecosystem equilibrium and sustainable fishing. 

NOAA science also informs about escalating climate impacts

The plan to dismantle NOAA could not come at a more perilous time for people facing threats to their lives and property from extreme weather and climate change.

NOAA reported that during 2024, at least 568 lives were lost in 27 separate disasters that each cost at least $1 billion in the US, for a whopping total of at least $182.7 billion.  These costs continue to climb year after year as wildfires, floods, hurricanes, droughts, and heat waves decimate communities across the country.

Whether you accept climate change science or not, you cannot erase your risk in a warmed and warming world (read here for ten signs of climate change). One of our most powerful tools against fierce, deadly weather is the ability to predict where it will affect us. That is what this administration threatens to take away.

 

Disasters with total economic losses of at least $1 billion dollars. Source: NOAA. NOAA is paid by the people, for the people, not special interests

Fishermen on the Eastern shore of Maryland are feeling the pressure of climate change impacts on their yield and seasons. Farmers across the Midwest are reeling from droughts and floods. Outdoor workers are dying from extreme heat. Schools are not letting children out to play on extremely hot days.

The number of billion-dollar weather and climate disasters keeps increasing: the 1980–2024 annual average is 9 events; the annual average for the most recent 5 years (2020–2024) is 23 events. The consequences of climate change and its impact on people, the economy, and infrastructure cannot be ignored by attacking an agency that actively helps prepare for said impacts with reliable, freely available data.  

NOAA is the go-to agency for scientifically-accurate global and regional atmospheric and oceanic conditions. The data collected by NOAA is used in forecasts and projections that save lives across the country.  

As we’ve said before, NOAA creates and advances climate science research to lay the unbiased, scientific bedrock of data and information for decision and policy-making that can deliver for us a climate-resilient future. We need to invest in and support—not dismantle—their mission to understand climate change to benefit current and future generations.  

NOAA belongs to us, is paid by us, and cannot be taken away from us. Why is Congress allowing an unelected billionaire to unleash his private army of tech goons on NOAA and illegally enter and usurp its functions and information technology systems? If Congress does not put a stop to this, one day we may wake up without extreme weather alert information. One day, we may wake up to a terrible storm we should have seen coming. 

Sea levels are rising, and science shows they will continue to rise for generations due to heat-trapping emissions that have already been released. This highlights a profound and enduring climate injustice: future generations will face the consequences of today’s decisions. The effects of these emissions are already unfolding, but the full extent of their impact—on coastlines, communities, and ecosystems—will play out over lifetimes to come.  

Understanding sea level rise as a long-term, multi-generational problem is essential to comprehending the scale of climate change and the need for bold action now. While this knowledge may be sobering, it underscores the importance of reducing emissions, holding major polluters accountable, and adapting to a changing world. Let’s explore what is driving this persistent rise and what it means for our collective future. 

What do we know about future sea level rise? 

Sea level rise is one of the most well-documented and predictable consequences of climate change, with models showing that average sea levels will increase over time, even in optimistic versions of the future. Scientists use computer models, such as climate models, ice sheet models, and sea level models, to make projections of future climate change. Projections of sea level rise, such as those contained in the Intergovernmental Panel on Climate Change (IPCC) 6th Assessment Report, give us an idea of what might happen in the future.  

These projections are usually based on a combination of two things: the heat-trapping emissions that have already occurred in the past and those that could occur in the future.  

The future trajectories are based on different scenarios, such as versions of the future where the world comes together to take action and phase out fossil fuels, or versions where fossil fuel production continues throughout this century. These different future scenarios, combined with what we already know happened in the past, give us a range of possible future sea levels.  

Most simulations focus on the near-term impacts by 2100, but some look forward multiple centuries to 2300, and occasionally some look even farther into the future, looking ahead 2,000 or even 10,000 years. 

Even in the most optimistic scenarios, where global average temperatures are kept below 1.5°C, model projections show that sea levels could still rise by approximately 11-22 inches higher than present by 2100. This would cause dramatic changes in island and coastal communities. Looking further into the future, the impact is even larger. Over the next 2,000 years we could see sea levels rising as much as 7.5-10 feet. Over the next 10,000 years, as much as 20-23 feet. If the world surpasses 1.5°C of warming and instead warms by 2°C the world could endure even worse outcomes with sea levels rising 7-20 feet over 2,000 years and 26-43 feet over 10,000 years. 

Looking at future sea level rise in this way gives us a combined look at the impact of both past and possible future emissions. But what if we want to know the impact of past emissions separated from the impact of future emissions? For that, we need to separate the impact of emissions that occurred over different time periods, and we need to understand the processes that make sea level rise such an enduring challenge. 

What causes sea level rise to persist for centuries?  

Because of the way the climate and ocean systems respond to heat-trapping emissions, sea levels will continue to rise even after air temperatures stabilize. This has been noted as a source of climate injustice, due to the profound impacts on future generations and low-lying coastal communities. 

The way air temperature responds after emissions cease is called the zero emissions commitment, or ZEC. Research with climate models in recent years shows that when carbon dioxide emissions stop, the rise in atmospheric temperatures will likely also stop. This means that there would be no additional warming of the atmosphere from carbon dioxide itself, but the many complex systems on Earth will continue to respond to the heat already trapped.  

So, even in a future scenario where the world achieves the stabilization of air temperatures, the Earth’s oceans and cryosphere (frozen regions like Antarctica) will continue to adjust. The oceans absorb much of the carbon dioxide lingering in the atmosphere, which contributes to ocean acidification. Meanwhile, increased atmospheric and ocean temperatures cause glaciers and ice sheets to melt and oceans to expand. 

The two dominant contributing factors to rising sea levels are: 

• Thermal Expansion: As the oceans absorb heat, the water expands, accounting for a significant portion of current sea level rise. 

• Melting Land Ice: When global mountain glaciers and the ice sheets in Greenland and Antarctica melt, they add mass to the ocean. The combined melt of all land ice is currently the dominant driver of sea level rise, and this trend is expected to continue into the future.  

Given that air temperatures stabilize when heat-trapping carbon dioxide emissions stop, yet sea levels continue to rise, we might then ask, what is the zero emissions commitment for sea level rise? How much would sea levels rise in the future just due to the impact of heat-trapping emissions that have already occurred in the past? 

Delaying emissions reductions leads to higher long-term sea level rise 

Scientific answers to these questions are just beginning to emerge. A few studies give us insight into the committed sea level rise that can result just from emissions that have already occurred in the past. One team found that emissions just up until 2016 could lead to approximately 2.3–3.6 feet of sea level rise by 2300—even if no other emissions happened after 2016. For reference, averaged across the Earth, sea levels have risen about 8 inches since 1901, meaning the full impact of past emissions has yet to materialize in our oceans and that future sea level rise in the coming centuries just from emissions that occurred before 2016 will exceed what we’ve experienced to date.  

Another study looks at how delays in reducing heat-trapping emissions impact sea level rise across centuries. ​​They find that for every five years that the world delays the reduction of carbon dioxide emissions, we commit the future to a median level of an additional 8 inches of sea level rise at 2300.   

Ice sheet tipping points: A critical threat 

Ice sheets have the potential to become the dominant factor in long-term sea level response. 

One of the biggest challenges with ice sheets is that they are considered tipping elements—meaning that they can pass a threshold beyond which large scale mass loss becomes effectively irreversible on human-relevant time scales. This is especially true for the marine-based ice sheets in Antarctica, which are undergoing ice loss due to warm temperatures in both the air and the ocean. While the precise warming threshold for ice sheet tipping points is still unclear, research on times in Earth’s history where the ice sheets underwent enormous changes tells us that it could happen even at a temperature rise of around 1.5-2°C above the preindustrial average.  

That’s why climate scientists are sounding the alarm—because global efforts under the Paris Agreement to keep warming below those levels are far off track. Current pledges countries have made under the Paris Agreement are projected to lead to around 3°C of atmospheric warming by the end of the century, which means we are at risk of triggering irreversible ice sheet tipping points.  

Understanding these processes underscores the critical need for immediate and sustained global action to reduce emissions. Strong action to reduce heat-trapping emissions now can protect the ice sheets and limit long-term sea level rise. But the longer we delay, the greater the risk of crossing irreversible tipping points and exacerbating the impacts of sea level rise for centuries to come. 

Act now to reduce impacts later 

The multi-century impacts of sea level rise underscore the urgency of phasing out fossil fuels and holding major polluters accountable for their role in driving climate change. While we cannot undo the impacts of past emissions, we can limit additional damage by taking bold action now. Understanding the science behind long-term sea level rise empowers policymakers, advocates, and communities to demand accountability and push for equitable solutions to this intergenerational crisis. 

This concept of long-term sea level response serves as the foundation for ongoing research that quantifies the multi-century impacts of emissions from specific industries, paving the way for informed decision-making and climate accountability. 

We already see coastal communities around the world struggling to cope with flooding, storm surges, and salty ocean water contaminating freshwater reservoirs. But as enormous as the burden to adapt to present problems is, these changes are small compared to the extent of adaptation that will be needed as sea levels continue to rise.  

People around the world are speaking up and calling for action. World’s Youth for Climate Justice has spoken out about the intergenerational issue of rising sea levels. The Alliance of Small Island States has been working diligently for 30 years to get the world to address the climate injustices of sea level rise.  

Court cases are being filed to demand action. This past summer, the International Tribunal for the Law of the Sea (ITLOS) issued an Advisory Opinion stating that heat-trapping emissions constitute pollution of the marine environment which drives sea level rise. The court noted that nations have obligations under international law to reduce this pollution. Taking action to phase out fossil fuels is not only the right thing to do, it is a requirement under international law.  

We know that sea levels will continue to rise for hundreds to thousands of years, but to what degree is not yet set in stone. We know that heat-trapping emissions must decline and reach zero as soon as possible. And what we need now is for world leaders to fulfill their legal obligations and act now for the sake of future generations. 

On January 10, NASA and the National Oceanic and Atmospheric Administration (NOAA) released their annual analysis finding that 2024 was the hottest year on record globally and that global average temperatures likely surpassed an increase of 1.5° Celsius above pre-industrial levels.

On the same day, NOAA released its US Billion-Dollar Weather and Climate Disasters analysis for 2024 and found that last year an estimated 568 people in the US lost their lives to 27 weather and climate disasters that each had $1 billion in damages or more with a total tallied cost of $182.7 billion.

The same agencies have found that the 11 warmest years in the historical record have all occurred in the past decade, and that each of the last 6 decades was hotter than the last.

Human-caused climate change, driven primarily by the burning of fossil fuels, is contributing to the hotter climate and more severe disasters, which include extreme heat, wildfires, intensified storms, drought and flooding. More people living in risky areas and the higher costs of damages are also adding to the trend of increasing billion-dollar disasters. People’s lived experiences throughout these deadly and terrifying events are the reason communities are feeling a sense of whiplash when it comes to the frequency and intensity of climate disasters.

During these uncertain times, as President Trump is nominating individuals to lead federal agencies, if there is one agency that could truly benefit from a steady, experienced hand at the helm, it would be the Federal Emergency Management Agency (FEMA) whose sole mission is to help people before, during and after disasters.

 Here are five things the nation needs from the next FEMA Administrator:

1. Defend against mis- and disinformation about disasters

To have the US president spreading misinformation and disinformation when it comes to emergency management and disaster recovery is reckless and dangerous because it could literally be the difference between life and death. The next FEMA administrator will need to defend against a marathon of false information by President Trump who has a fondness for distorting facts when it comes to disaster response and recovery.

The president lied about the devastating Hurricanes Helene and Milton that created confusion among disaster survivors while local, state, and federal government officials took time and energy to repeatedly communicate the facts. The previous FEMA administrator Deanne Criswell said the level of disinformation is at a point that she’s “never seen before.”

Then, as if witnessing the horrific wreckage of the LA fires isn’t disturbing enough, President Trump and some members of Congress spread mis- and disinformation about the cause of the fire and firefighting efforts. 

As my colleague Astrid Caldas explains, misinformation is the unintentional spread of false information while disinformation is spreading false information to be deliberately misleading. Given the level of harmful disinformation in the news regarding the LA fires, California Governor Newsom created a webpage to set the record straight. My colleague Juliet Christian-Smith wrote Six Facts About Water and Wildfire in the West to correct some misconceptions about why the fires are so bad.

I’m unclear as to why President Trump has decided to punt FEMA into the political crosshairs but one thing that is clear is the rampant misinformation about what FEMA actually does. The fact is, that disaster assistance has generally been a bottom-up approach in the US. For example, local/state/territorial and tribal governments already take the lead on emergency response, period. FEMA comes in only after a state has requested a disaster declaration for those catastrophic events in which the state does not have the financial or staffing capacity to respond on its own.  When it comes to disaster response and recovery, the role of FEMA is to supplement not replace state/state/territorial and tribal efforts.

The next FEMA Administrator is going to have to navigate skillfully, follow the science, ignore the bluster coming from the White House, and work overtime to overcome the public skepticism it creates. Lives and livelihoods will hang in the balance.

2. Defend the Stafford Act and ensure disaster relief is equitable and bipartisan 

The new FEMA head will have their work cut out for them to ensure that all states, localities, territories, and tribes are treated equally when disasters hit.

Adding salt to L.A.’s wounds, both President Trump, Congress and House Speaker Mike Johnson have been politicizing FEMA disaster assistance by suggesting that they support putting conditions on federal aid to help the victims of the Los Angeles wildfires.

Under President Trump’s first term, investigative reports found that President Trump initially refused to provide California disaster aid after the deadly wildfires in 2018 because of the state’s Democratic leadership. They also found that the White House Office of Management and Budget (OMB) head, Russell Vought, delayed disaster aid to Puerto Rico for months after the Hurricane Maria devastation. Vought, a co-author of the dangerous Project 2025, is Trump’s pick again to lead OMB.

The notion of withholding disaster assistance unless a state or jurisdiction passes certain policies is simply against constitutional law according to Berkley Law expert Dan Farber.  As Mr. Farber points out, while the president does have broad discretion, Congress does not and must guide the use of executive discretion. Congress clearly notes this guidance in the first section of the Robert T. Stafford Disaster Relief and Emergency Management Act (“the Stafford Act”) which is “to provide an orderly and continuing means of assistance by the Federal Government to State and local governments in carrying out their responsibilities to alleviate the suffering and damage which result from such disasters…”. 

If the president blatantly ignores the law, who knows what will happen to communities suffering as they try to recover and get their lives back after a disaster? The next FEMA Administrator must help set the record straight on FEMA’s mission and the Stafford Act to ensure the president provides disaster assistance to everyone who needs it, regardless of whether they live in a red or blue state.

3. Advocate for robust funding for FEMA, the Disaster Relief Fund, and preparedness

The next FEMA administrator should work to make the case to Congress and the White House for robust appropriations for the agency, its staffing (currently experiencing a 35% gap), the Disaster Relief Fund, and preparedness and risk reduction measures.

According to the Congressional Research Service (CRS), the US averaged 25 major disaster declarations a year from 1979 to 1988 (the first decade of FEMA’s existence). That average rose to 63 over the last ten years, an increase of approximately 150%.

The same CRS analysis finds that in 2020, obligations from the Disaster Relief Fund exceeded an estimated $40 billion for the first time and have consistently reached that level every year since. While the “major disasters” portion of the Fund was initially expected to last into the middle of Danger Season (May through October), recent emergency funding was approved prior to the LA wildfires, the costs of which will be enormous.

The science is clear, as the planet continues to warm, we will see greater risks of chronic impacts, including higher rising seas, killer heat, and hurricanes that are dumping heavier rainfall.

Although FEMA and Congress have supported more funding for risk mitigation it’s not close to what is needed. The Fifth National Climate Assessment finds that the scale of adaptation (reducing risks and preparing for future risks) must accelerate dramatically given the unprecedented rate of climate change.

Currently FEMA spends 7x more on disaster response and recovery than on mitigating disaster risk even though data show the cost savings to FEMA (in addition to preventing the loss of life and disruptions to daily life) of reducing risk totals roughly $700 million annually. The next FEMA Administrator must advocate for funding levels necessary for both the ounce of prevention andthe pound of cure.

4. Play defense and offense: defend against Project 2025’s proposals and hold firm on climate science and integrity

We will need the next FEMA administrator to fend off Project 2025’s anti-science playbook. Project 2025 is the policy agenda put forth by the Heritage Foundation that has been described as an authoritarian playbook. My colleague Rachel Cleetus wrote passionately on the impacts of the agenda when it comes to climate action and disasters:

“Anyone sobered by the relentless rise in global average temperatures and the spate of devastating and costly extreme weather and climate disasters we’ve been experiencing, anyone who thinks policies to benefit the public should be informed by robust, independent science, should take this threat very, very seriously.”

The two page section on FEMA (see p. 153) explains how it would essentially gut the agency’s mission, reduce disaster assistance and resilience funding to state and local governments, and bury the agency within a different department from where it currently sits under the Department of Homeland Security (DHS).

The FEMA Administrator should strive to leave the agency stronger, not weaker, than they find it and oppose Project 2025’s proposals. Instead, the new agency lead should embrace and advance the great strides accomplished by the office of Resilience including issuing guidance reports including its 2022-2026 strategic plan, Response and Recovery Climate Change Planning Guidance, adaptation planning, and alliances for climate action as well as training and tools such as the Resilience Analysis and Planning Tool (RAPT).  

5. Understand the inequities of fossil-fueled climate disasters and prioritize equitable preparedness

The next FEMA administrator must understand that fossil fueled, climate-related disasters and extreme weather do not discriminate when it comes to political boundaries or affiliations. They have to know that climate impacts aren’t distributed equally among underserved and marginalized communities who regularly face disproportionately worse impacts from these events.

Over the years, FEMA has worked to make their grant programs more equitable. The most visible effort has been through the implementation of the Justice40 program that set the goal for federal agencies to target at least 40% of certain federal resources to benefit historically disadvantaged communities.

In one broad brush stroke, President Trump rescinded 78 Biden-era executive orders, including the Executive Order 14008 “Tackling the Climate Crisis at Home and Abroad” which established the Justice40 program. Both FEMA’s Building Resilient Infrastructure and Communities (BRIC) and Flood Mitigation Assistance (FMA) fall under the Justice40 Initiative to meet environmental justice and equity goals. FEMA announced in July 2024 that they exceeded that 40% goal for BRIC by 67% for the sub-applications and 70% for the national competition.

The FEMA mitigation grant programs, particularly the BRIC program, are continuously oversubscribed —for example, in 2024, FEMA received 1,234 sub-applications requesting $5.66 billion in federal cost share, yet FEMA had funding to award funding to 656 sub-applicants, that totaled more than $882.6 million in federal cost share.

Project 2025 put a target on environmental justice by proposing to eliminate the EPA Office of Environmental Justice and External Civil Rights and the Justice40 program, which President Trump did on his first day in office with his Executive Order entitled Initial Rescissions of Harmful Executive Orders and Actions.

Given the daunting risks and impacts of the climate crisis and the overwhelming need for risk mitigation and preparedness resources, the next FEMA administrator must make the case for robust funding for these pre-disaster mitigation grant programs and for the processes in place that make the distribution of these resources more equitable.

There is good news for advocates of just disaster relief

As the nation recently celebrated the life of President Jimmy Carter, one achievement of his that may have been overlooked is his establishment of FEMA 46 years ago. Since that time, FEMA has gone through many changes. But over the years, one hopeful note is that most former FEMA administrators have had considerable backgrounds in emergency management.

In normal times when we could rely on the adage that if the past is prologue, we could rest assured that the next FEMA administrator nominee will have an emergency management background. This is especially true given that the Post-Katrina Emergency Management Reform Act of 2006 (see p. 245) law requires that the administrator shall have demonstrated emergency management and homeland security knowledge and background and have a minimum of 5 years of executive leadership and management experience in the public or private sector.

Unfortunately, President Trump has nominated inexperienced, anti-science and extremists to run cabinet level positions, see for example nominees for US Department of Agriculture, US Department of Energy and the Department of Justice, that pose great dangers to the missions of these departments and the communities and business they support. In a similar fashion, President Trump has nominated an inexperienced interim FEMA acting director, Mr. Cameron Hamilton, a former navy seal who has no disaster management experience.

However, an early report suggested that President Trump may pick the Florida Division of Emergency Management Executive Director Kevin Guthrie to run FEMA. Mr. Guthrie has been with with the Florida Division of Emergency management for over six years and has an additional ten years of emergency management experience. So while he certainly holds a limited resume in the emergency management field, he understands the field and has been working in a state in which from experienced 19 disasters from 2023 to 2024 that each cost over a billion dollars.

Here’s hoping the President Trump follows the law and the next FEMA nominee has an emergency management background.

Editor’s note: Updates first paragraph for clarity

In late 2024, as part of a bipartisan funding bill, Congress authorized $110 billion in disaster recovery funds across federal agencies. Following Congress’ appropriation, The Department of Housing and Urban Development (HUD) announced how their $12 billion tranche of disaster recovery funding would be divided among disaster-impacted communities at the city, county, and state levels. This funding, known as Community Development Block Grants for Disaster Recovery or CDBG-DR is intended to be flexible and allow recipients to design programs that respond to the local post-disaster needs. Usually CDBG-DR programs fall into one of three categories: housing, infrastructure repair, or economic revitalization.   

Disasters and the complicated process of recovering from them can deepen pre-existing inequality–a study of FEMA disaster aid on a county level found that awards exacerbated the racial wealth gap. The longer communities must wait for disaster funds to flow, the greater the financial and emotional strain on households.

Now that CDBG-DR funds have been allocated, there’s an enormous opportunity across 23 states and one territory not just to rebuild, but to create more equitable and resilient communities in the face of growing risk.  

What climate leaders and program administrators can do  

Following years of pressure by disaster survivors and advocates, HUD recently changed its program requirements to make disaster recovery more equitable. As cities, counties, and states that received CDBG-DR allocations create their required action plans to submit to the federal government, they should keep in mind the following recommendations alongside input from disaster survivors.    

Stick to 70%  

Federal rules around CDBG-DR funding require that 70% of funds be spent on activities that benefit low-to-moderate income households who find it harder to recover from increasingly severe and frequent disasters. Recipients of CDBG-DR funds can request to have that threshold lowered to 51%. An audit of CDBG-DR programs from 2001-2019 found that 137 of 193 grantees reviewed had reduced their requirement to 51%. At a time when more and more Americans are experiencing damage and displacement from extreme weather as a pocketbook issue, it’s critical that public officials from local governments all the way up to HUD staff honor the 70% requirement.   

Dovetail and Accommodate to Deepen Impact  

Disasters don’t occur in a vacuum–those that struggle to access long-term recovery assistance are often facing multiple challenges, something program administrators acknowledge, but find difficult to address.  In order to design and implement impactful long-term recovery, investments should be made in accommodations that ensure equitable access to recovery resources like providing transportation and home visit options for mobility-impaired residents and ensuring language accessible program materials.    

In addition to providing accommodations, administrators should also dovetail disaster recovery applications with trusted local programs that already reach vulnerable populations to deepen impact. A key challenge when homes are damaged or lost during a disaster is to ensure that eligibility requirements are inclusive and don’t worsen disparities. 

Take for example, the residents of heirs’ properties–where homes are passed down through generations without legal title. Heirs’ property is a common practice in Black communities born out of discrimination by lending institutions and the government and can make navigating disaster recovery programs especially difficult.

Following years of advocacy, including a lawsuit by disaster survivors in North Carolina, the federal government now requires programs to allow for alternate means of demonstrating ownership. After identifying heirs’ properties through disaster recovery efforts, survivors could be “funneled” into legal clinics to resolve their title issues and safeguard family wealth. Administrative pipelines between disaster programs and other services for populations that struggle to access aid hold enormous potential to improve public health outcomes and advance economic and racial justice.  

Remember Renters 

Across the country, more people rent their homes than ever before.  Despite a long-term trend in increased rentership and heightened political urgency around the affordable housing crisis, renters receive less initial disaster aid compared with homeowners. In the days and weeks after a disaster, renters may face dubious evictions and illegal price gouging when trying to secure alternative housing. 

While long-term recovery programs can’t prevent these costly and stressful experiences, they can be designed to be more responsive to renters’ needs. This might look like increasing the supply of meaningfully affordable housing by deepening subsidies for new development, repairing or providing resilience upgrades to existing affordable housing without pricing out tenants, preserving long-term affordability by transferring rental properties into a community land trust or investing in legal services for renters.   

A drop in the resilience bucket  

CDBG-DR funds will not meet all the resilience or housing needs of disaster impacted communities.  Other parts of the $110 billion disaster spending package passed will address different types of recovery efforts–from improving water systems to repairing public facilities and supporting agricultural recovery.

Still, this funding is a drop in the bucket.  Communities across the country deserve proactive and equitable investment in the face of growing climate risk and an affordable housing crisis. Until there’s the political will to make those life-saving investments–and to curb emissions to limit how much worse fossil-fueled climate disasters get–every drop in the resilience bucket counts and should be invested in ways that have the most equitable impact.

While watching the latest disaster movie is a pastime for many, living through extreme weather and climate disasters is painfully difficult for the people affected. It is made more difficult by a President who scorns disaster victims, as President Trump did to Puerto Ricans after Hurricane Maria, and spreads disinformation, as he did to Californians during the recent Los Angeles wildfires.

Now President Trump has revoked Executive Order 13985 (Advancing Racial Equity and Support for Underserved Communities Through the Federal Government) and Executive Order 14008 (Tackling the Climate Crisis at Home and Abroad), with far-reaching implications for people in disaster areas, including how racial equity is addressed in disaster relief and recovery. Revoking these orders sends the US in the wrong direction as we face increasing danger from extreme events, such as Hurricane Helene in North Carolina.

Watching the administration unravel racial equity programs at federal agencies is its own disaster-in-the-making, on top of disasters guaranteed to come—like a disaster movie layered on a horror flick that the entire country will eventually experience.

If this was a movie, here is how it would play out.

(Spoiler alert: ignoring racial equity in disaster resilience will cost all of us more and lead to increasingly unfair burdens on already underserved communities.)

THE PREQUEL: Ignorance is not bliss

One important job of the federal government is to distribute billions of dollars to address the impacts of climate and other disasters. This function will be even more important with new executive orders that promote fossil fuels and end policies that reduce heat trapping emissions to limit the impacts of climate change.

To ensure the most effective use of our hard-earned taxpayer dollars for disaster response, recovery, and resilience, it makes sense to pre-position resources in the areas of highest need. Some communities—such as low-wealth communities or communities of color—are disproportionately impacted by disasters, in part because of historical or systemic disparities. A laser-like focus on assessing social inequities is thus essential for understanding where the highest areas of need are and to evaluate whether they are being assisted adequately. In short, matching disaster policy to social needs requires assessment of racial equity.

SCENE 1: The inequity avalanche

When racial equity is ignored, disaster policies exacerbate existing inequities. Policies based solely on “merit” fail to recognize the steeper hill being climbed by historically underserved communities granted less access to resources, information, and decision processes.

After Hurricane Katrina struck New Orleans in 2005, Black residents returned to the city more slowly than White residents. Research by Elizabeth Fussell and her colleagues suggests that the racial disparity was explained by housing damage, rather than by socioeconomic status or other demographic characteristics. Put plainly, Black residents’ delayed return occurred because they suffered more severe housing damage, which occurred because they tended to live in areas that experienced greater flooding. A higher concentration of Black residents in the lower-lying parts of the city exists because of historical patterns of land development and residential segregation that resulted from the racist system of redlining. Without a focus on racial equity, disaster policies don’t just leave these communities behind, they in fact compound the health, environmental, and economic challenges being faced.

SCENE 2: The communication breakdown

Effective risk communication is crucial for disaster resilience. However, when racial equity is censored, communication efforts fall flat. Without a deep understanding of the social, economic, health, environmental, and cultural context in which a disaster is unfolding, critical information may not reach those who need it most. We saw this recently in Los Angeles with fire evacuation notices not reaching the unhoused population.

Not including racial equity considerations in the planning and implementation of risk communications ignores basic science, which in turn costs lives and money. The latest resilience research and practice emphasizes a multifaceted, “adaptive systems” approach to risk communication and decision making. This approach recognizes diverse perspectives, experiences, education levels, languages, and technological skills and the need for evidence-based deliberations before, during, and after disasters. We must first acknowledge and understand this diversity to be able to highlight the most effective pathways to disaster mitigation and resilience.

SCENE 3: The phantom of the funding

When federal funds for disaster resilience are distributed based on formulas that do not account for unique challenges, an uneven distribution of resources results, with some communities receiving more support than others. One example is FEMA’s flood mitigation grant program, which requires a cost-share by the community applying for the grant. Low-income neighborhoods and communities of color are less able to meet the match requirement, so FEMA has invested significantly more in wealthier, White neighborhoods (which reduces insurance costs and increases property values in those areas). If the Heritage Foundation’s Project 2025 blueprint is implemented, the cost-share requirement for communities will climb steeply.

Analyses of OpenFEMA data has found that disaster assistance funds are often distributed inequitably (controlling for total damages), such that as the percentage of racial and ethnic minority populations increase, the amount of assistance decreases. This disparity is set to increase with the new administration’s revocation of environmental justice directives.

SCENE 4: The resilience mirage

When racial equity is not integrated into disaster resilience policies, the concept of resilience itself becomes a mirage—an illusion of safety and preparedness that doesn’t hold up under scrutiny.

True resilience includes everyone, particularly those who have been historically marginalized. The pattern of impacts from events such as Hurricane Katrina reveal that response strategies that may seem comprehensive on paper, in fact leave certain groups disproportionately affected. Integrating racial equity into disaster resilience policies is essential to ensure that all communities are genuinely supported and protected in times of crisis.

GRAND FINALE: A call to action

So, what’s the moral of this cautionary tale? Integrating racial equity considerations into disaster resilience policymaking is not a luxury—it’s a necessity. By addressing the systemic inequalities that contribute to the disproportionate burdens borne by already underserved communities, we can develop policies that enhance resilience for everyone.

To our decision makers: It’s time to embrace the robust scientific evidence already available and ensure that disaster resilience efforts are inclusive, fair, and effective.

And to our readers: Stay informed, stay engaged, and keep reminding your elected officials that you care about the use of sound science in policymaking.

As part of his wide-ranging first-week activities, President Trump issued a barrage of executive orders specifically intended to boost the fortunes of the fossil fuel industry.   

Not for the betterment of the US public, as these actions would freeze, repeal, or actively undermine critical public health and environmental protections. 

Not for the betterment of the US economy, as these actions would undermine billions of dollars of forward-looking investments, cede leadership in innovation, and spike household energy bills. 

Not for the betterment of US energy abundance, as these actions sideline critical clean energy resources and threaten to stall the deployment of more.  

Not for the betterment of US global standing, as these actions would aggravate areas of escalating geopolitical risk and spurn areas of productive geopolitical coordination.  

Not for the betterment of anything beyond boosting the bottom line for a select polluting few.  

Now, there’s a yawning gap between President Trump’s bold pronouncements and his actual ability to see many of these things through. Much of it will simply amount to hot air.  

Still, there’s a roadmap here. And if not by executive order, this administration has made clear from the jump that it will try anything to deliver for fossil fuel interests, no matter the public cost.  

That makes understanding the what and the why critical, to be prepared for all the attacks to come. So here: a look at the Trump administration’s first moves in its whole-of-government approach to selling out the nation. 

A whole-of-government approach to selling the nation out 

The fossil fuel industry’s wish-list is sprawling. So too is the range of new executive orders designed to be to the industry’s benefit.  

On Day 1 alone, President Trump issued executive orders declaring a national energy emergency, exiting the Paris Agreement, halting offshore—and some onshore—wind development, “unleashing” American (fossil) energy, and expanding fossil fuel production in Alaska. These occurred alongside other executive orders striking down large numbers of cross-cutting federal initiatives, including those coordinating climate, environmental justice, and public health protections.  

President Trump has framed these early actions as intended to improve the nation’s economy by lowering energy costs—but the claim is immediately, preposterously undone by the logical incoherence of his actions.  

For at the exact same time President Trump declared an energy emergency, he simultaneously attempted to derail new offshore wind development, which would undermine reliability, and directed agencies to take actions that would decrease the efficiency with which we use energy, which would drive up consumer energy costs. He also froze funding specifically intended to spur the deployment of new energy resources across the country, as well as infrastructure intended to boost energy reliability, resilience, and access.  

Some way to solve a “crisis.” 

When you peel back the rhetoric, it’s clear there’s only one throughline here: actions that would boost the profits of fossil fuel companies, with the costs borne by everyone else. 

And that strategy makes sense when remembering that this is an administration that pledged fealty to fossil fuel executives so long as they opened their wallets during campaign season—which they did. Because ultimately, fossil fuel executives don’t want to drive down energy prices. They want higher earnings, achieved by lowering their costs of doing business while locking in long-term demand for fossil fuels. 

How the executive orders advance fossil fuel interests 

The executive orders attempt to advance fossil fuel interests through two main approaches: first, by making it easier to extract and transport fossil fuels, and second, by making it easier to use fossil fuels—including by making it harder to use clean energy resources instead.  

Making it easier to extract and transport fossil fuels. US fossil fuel production is at record highs. There is no shortage of fossil fuel production, nor—problematically, to our eye—is there any shortage of opportunities for future expansion. But fossil fuel companies object to any constraints on their ability to extract fossil fuels, wherever and however they want.  

Moreover, fossil fuel pipelines crisscross the nation and liquefied natural gas (LNG) terminals extend the reach of gas transmission from within the country to around the globe. New pipelines, and new LNG terminals, are actively under construction—the latter of which are already projected to nearly double LNG capacity by 2028. But fossil fuel companies object to standards and accountability around where, how, and to what end those pipelines are constructed, as well as commonsense evaluations of the harmful economic, climate, and health implications of unfettered LNG expansion.  

The Trump Day 1 orders attempt to appease fossil fuels interests on these fronts by opening more areas for leasing; attempting to shortcut the permitting process for fossil fuel infrastructure—both by claiming an energy emergency to sidestep regulatory requirements and by attempting to unwind decades-old permitting processes and requirements; pushing the Department of Energy to advance LNG approvals; and directing agencies to review (and, implied, weaken or fully rescind) regulations governing pollution associated with fossil fuel extraction, processing, and transport.  

Making it easier to use fossil fuels. Fossil fuels are intertwined throughout the US economy—but less so every day. Renewable resources and energy storage are rapidly displacing coal-fired power plants and edging out gas-fired generation. Moreover, people are increasingly pivoting away from fossil fuel-burning end uses, such as vehicles, stoves, and furnaces, to electrified alternatives, such as electric vehicles (EVs), induction cooktops, and heat pumps. This existential threat of obsolescence means that even if fossil fuel extraction and transmission were fully unencumbered, if nobody wants what fossil fuel companies are selling, there’s nothing left to prop up. Queue the out-of-the-gate attempts to force ongoing fossil fuel consumption, following a two-pronged approach.  

First, President Trump directed agencies to discount, ignore, and potentially even outright reject the premise of, the harms of fossil fuel use to public health and the climate, thereby attempting to create a route to justify the weakening of pollution standards—which he also directed agencies like the EPA to reconsider. He also initiated the process of once more pulling out of the Paris Agreement, in so doing pivoting away from the single greatest commitment to global climate action. 

Second, President Trump attempted to derail the competitors to fossil fuel use, namely renewable resources like wind, solar, and storage, as well as energy end uses like EVs and heat pumps that run on electricity or, even, just more efficient use of fossil fuels. This included freezing federal leasing and permitting of offshore wind; freezing the disbursement of funds intended to support the clean energy transition at the individual, community, state, and national levels; and freezing the disbursement of funds loaned to companies investing billions of dollars in new US manufacturing facilities to advance innovative clean energy technologies.  

What comes next 

With these executive orders, alongside a slew of fossil fuel-friendly agency nominees, the Trump administration has made clear who’s once again calling their energy shots.  

However, vanishingly little of what’s been proposed thus far is at all guaranteed of coming to pass. Indeed, the overwhelming majority is directional at best, with no follow-through required. And even where there is follow-through, actual changes resulting from these orders will face substantial hurdles. 

When it comes to unwinding regulations, agencies like EPA will have to justify their actions—and that means actually looking at the science. The Trump administration immediately leapt to undermine that very science on Day 1, too, but even with these bald-faced instructions to outright deny reality, agencies will still have to contend with the facts, as well as the long and winding processes associated with administrative procedures.  

When it comes to halting the disbursement of funds from policies that have already been passed into law, such as those via the Bipartisan Infrastructure Law and Inflation Reduction Act, that means halting the disbursement of funds that are legally owed. To change the flow of funds, Congress must pass new laws—or the president risks outright violating the constitution. 

Finally, when it comes to popular buy-in, the administration will have to contend with the fact that people overwhelmingly favor clean air and commonsense standards; that people support innovation and advancement of clean energy technologies; and that people want real solutions to the devastating, escalating, staggeringly costly impacts of climate change.  

And those solutions? They sure aren’t this. 

Dear Colleagues,

We are living in an era where we must prepare for another dramatic pendulum swing in public policy. For those of you in federal government this is a known anxiety-provoker.

I worked at the EPA through multiple presidential transitions, including from President Obama to President Trump in 2017, and again the transition to President Biden in 2021. In this second Trump administration we know to expect attacks on federal science and federal scientists thanks to the President’s track record and his second campaign’s promises. Plus, there is the Project 2025 manifesto that lays out the plans of the new administration to repeal the gains made over the past four years and halt efforts to combat human-caused climate change and environmental damages alongside their inherent social inequities.

One of the pillars of the cynical Project 2025 agenda is to attack the underpinnings of federally funded science. Another is to attack the very people who work in regulatory programs of administrative agencies. I recall experiencing that jarring shift eight years ago. I wondered anxiously just how I might make it through. Many of my work friends in federal government found other work during the following years. I somehow stuck it out and have many lessons learned from that period.

What’s best for you is a very individual decision, but here are seven lessons I learned over the years as a federal employee.

1. Know you have allies in the NGO community who are cheering you on.

During the first Trump administration, I recall receiving postcards from random strangers thanking me for my public service. I realize now those postcard campaigns were organized by nongovernmental organizations (NGOs) like UCS. I also remember seeing small First Amendment-protected acts, such as signs hanging in individual’s office space that said, “No Sides in Science.” The signs came from a Save Science rally organized by the NGO community. Seeing these cheered me up.

2. Tune out the noise and don’t overreact to the hype.

Much of the hype in the mainstream media is exactly that. Even if you get your information from independent media or social media, it can be deafening to consume too much. One lesson from the prior Trump administration is how much bluster there was that didn’t come to pass. Do not despair pre-emptively.

3. Understand the motivations of political appointees in your agency.

Each political appointee will have some power and an ego to satisfy. They will need to negotiate with other appointees who have their own interests and levers of power. While there will be memos from on-high, such as orders to reduce staff, agency appointees will also have to make good on requests by stakeholders with influence in the political context of your agency. We know, for example, that during the first Trump administration some industries needed permits issued, so those industries argued in favor of keeping relevant staff at EPA. Also, local businesses supported maintaining programs that offered community redevelopment opportunities, including brownfields and Superfund site cleanup. After all, it does take a clean, healthy, thriving environment to run a successful business. And, thriving local economies make good news.

4. Don’t be a mind-reader.

If there is a mandate from above, it should come in writing. Based on what I saw in the last go-around, agency leaders will try to avoid written records. If they don’t send a memo or email instruction, you have the power to send a summary of their instructions via email and make a note for the record. 

5. Use the rules to your advantage.

There are laws that lay out the protocols and steps that government functions, including regulatory decisionmaking, should take. For example, government analyses need to be documented for the administrative record. And, many governmental functions require involved officials to adhere to ethics rules. Be it the Federal Advisory Committee Act, the Administrative Procedures Act, the Information Quality Act, or the Evidence Act—all those laws were created to keep meticulous account of the work of government. This is important for the long game and in cases where the Freedom of Information Act could be used to demonstrate instances of political interference or censorship.

6. Know the union resources and support that are available to you.

Much of the bluster we are hearing is about attacks on staff through changes to workplace conditions. Use your union contacts, even if you aren’t part of the union, to understand what is within bounds and what flexibilities you have. Demand those flexibilities before giving up on your job in the federal government.

7. Know your labor rights.

You have rights under federal labor laws. Make sure you understand those rights and your agency’s policies, including equal employment opportunity protections based on race, national origin, gender, and sexual orientation. There are organizations, like the Government Accountability Project, with lawyers on standby to support individuals who expect targeting.

I hope these seven lessons may be of some comfort to you during the coming months and years. In addition, here at UCS we have compiled this list of resources for federal science workers and have launched our Save Science, Save Lives campaign. We are actively working to ensure that senators ask President Trump’s cabinet nominees during their confirmation hearings about their plans for protecting science and scientific integrity. You can urge your senator to do so today.

I moved on from federal government two years ago. I continue to recognize the deep value of federal science and the system of regulations that were set up to protect those most vulnerable to the excesses of our socio-political system. This new administration has a particular view that is expected to attack the foundation of scientific integrity. We at UCS know this, and we stand ready to support those of you who want to keep your position in federal institutions. Not everyone may. We understand and respect that choice as well.

In solidarity,

Chitra

As the known drinking water nerd amongst my friend group, I have been informally fielding questions about whether their water is safe to use near the wildfires in Southern California. Some common questions I’ve heard include: How do I know if I can drink the tap water? Can I shower with it? When will it be safe? Beyond more generally getting the facts right on the water and wildfire issues in California, as this Guardian headline suggests, it’s smart to assume the worst about the safety of drinking water in and throughout the immediate aftermath of devastating disasters like the Los Angeles fires.

Why be concerned about the safety of your drinking water after a major fire?

As colleagues so comprehensively explained in their “Wildfire and Water Supply in California” report, there are a lot of pathways by which a wildfire can make your tap water unsafe (and a lot of great ideas on how to adapt to this growing challenge). In Northern California, the Tubbs Fire’s effects on Santa Rosa in 2017 and the Camp Fire, which burned the entire town of Paradise only a year later, were among the first wildfires known to cause widespread drinking water contamination in cities.

Wildfires in forests and wildfires in urban areas have different consequences. Alarmingly, after the Tubbs and Camp Fires, researchers found evidence of post-fire contamination from volatile organic compounds (VOCs) like benzene, which is carcinogenic, and also from heavy metals, microbes and other contaminants that pose both immediate and long term public health risks. As fossil-fueled fires get worse, tap water contamination concern grows. Drinking water may not be safe for months, depending on the severity of the damage.

To name a few ways water can be contaminated post-fire:

• Incineration of urban infrastructure—houses, buildings, electric wires, etc.—leaches toxic chemicals not only into our air but when hot enough, can melt the underground pipe network that deliver drinking water.
  
• Toxic runoff from the combination of burnt infrastructure, any fire retardant that has been dropped and water to fight the fires, infiltrates into the ground and any stormwater system.
  
• Any disconnection or disruption to an otherwise closed loop treated drinking water distribution system creates risks of contamination.
  
• Distribution network depressurization may also allow for contaminant transport between differently impacted parts of the distribution system.

I live in or near a fire-impacted community, what should I do?

Figure out who your water provider is if you don’t know. Community water systems provide drinking water for most Californians, and there are a few tools to consult to identify your water system:

• The Community Water Center’s Drinking Water Tool, features an address-based search tool available in Spanish or English.
  
• For residents of LA County, the UCLA LA County Water System Governance Map, shows the service areas for more than 200 systems in the county, and is available in Spanish or English.
  
• The state regulatory agency for drinking water maintains a Human Right to Water Portal, which is also address based and includes not only community systems, but also the schools and daycares responsible for complying with safe drinking water standards.  

Then, check your water provider’s website for any advisories like “do not use”, “boil water”, or “‘do not drink”’ notices. (Learn more from the CDC about the difference between them). Depending on the contamination issue, and unless advised by your water provider, it’s unlikely that you can self-treat the water to make it safe by boiling, filtering, adding chlorine or other disinfectants etc.

Check out the LAist Cheat Sheet which compiled thorough FAQ for LA area residents, including how to understand different advisory types, where to get replacement bottled water and your local water provider’s phone number to get your questions answers.

Areas affected by Do-Not-Drink-Water notifications and other water advisories are dynamic. Large water providers like Pasadena Water and Power and LA Department of Water and Power are actively testing and working to get water back to regulatory standards. Smaller systems may have a harder time recovering.

The above concerns and suggested steps are focused on the safety of the tap water being delivered to your house and do not address very real concerns due to on-site contamination from damaged infrastructure on private property. Always review official resources for those impacted by the LA Fires: https://www.ca.gov/LAfires/.

I have a domestic well, what should I do?

If you are not in the service area of a community water system, your house may have a private domestic well. All the fire-related toxic substances infiltrate the soil and reach our groundwater, they contaminate it with dangerous substances that any added chlorine or household point-of-use filters may not remove. That translates to a higher level of pollutants in our tap water, especially when fires occur near a drinking water well.

Domestic well owners are responsible for managing their own water quality, even when impacted by events outside their control. While a brand new law now requires landlords to ensure their rental properties’ wells are tested, there is no state agency that regulates domestic well water quality they way they do for water systems.

Some ideas on how to learn about the safety of your tap water:

• Assess your well if impacted by wildfire, considering using the CDC’s rapid assessment form
  
• Review the SWRCB’s Guide for Well Owners and Well Testing Program Directory, and search by your county to see if which programs are available in your area.
  
• Follow the CDC’s checklist depending on issues experienced from loss of power, to loss of pressure and hire licensed professionals to repair or replace damaged components.
  
• If your house also has a septic tank, check for any signs of damage that could cause issues for indoor plumbing or domestic well contamination.
  
• Review official state resources for those impacted by the LA Fires: https://www.ca.gov/LAfires/

Not impacted by the fires, but want to help? Fire recovery will be a long process, and donations of critical supplies like bottled water will be needed long after the media moves on from this disaster. Find a trusted local organization, like the Pasadena Jobs Center, an organization coordinating volunteers on the ground and recommended by a friend who grow up in Altadena and lost their family home in the Eaton fire. Consider directly supporting mutual aid groups now and in the coming months.

President-elect Trump’s threats to swiftly implement a policy of mass deportation for immigrants in the United States without legal status, as well as end programs that provide lawful temporary protected status for many immigrants, are inhumane. Immigrant rights groups and legal experts have rightly sounded the alarm and are working actively to fight back and resist these actions, which could be announced on Day 1 of the Trump presidency. All of us—whether we or our families, friends and community members are directly impacted or not—have a stake in understanding why these policies are so harmful, morally reprehensible, and have no place in a democracy.

We in the US are part of a country whose history and present-day social and economic realities are deeply intertwined with and built on the experiences of immigrants, enslaved African Americans, and Indigenous peoples. Owning that history—the good and the bad—is a crucial part of what it means to be an American. And it’s the first step in charting a path to a better, fairer future for our country.

The current US system of immigration is clearly broken, and across the political spectrum there is a recognition that reforms are urgently needed. I am not an immigration expert so I will not opine here on the details of those reforms.

What is clear—or should be clear—to all of us is that if we arbitrarily judge some immigrants to be “better” than others, we will inevitably risk reinforcing a system that is based on biased and unequal power and economic structures that are pervasive in the world today. All too often, current legal pathways to immigration privilege a subset of people while shutting out many who work equally hard and are equally deserving.

As my colleague Karen Perry Stillerman points out, in addition to being morally repugnant, mass deportation programs would have a significant negative impact on our nation’s food system, which could not function without the labor of immigrants.

As another example, as extreme weather and climate-related disasters mount across our nation, it is often immigrants who help to do the difficult and dangerous work of cleaning up debris and rebuilding homes and infrastructure as quickly as possible. As a recent news article points out:

“The fact is that the people who rebuild those areas—from Palisades to Malibu to Altadena—it’s immigrant construction crews,” said Pablo Alvarado, co-executive director of the National Day Laborer Organizing Network. “They’re the ones who are the second responders.”

Unfortunately, climate and fossil fuel-driven disasters are also contributing to a growing toll on people across the world, destabilizing economies, threatening livelihoods, health, water supplies, and food security. If we fail to sharply curtail heat-trapping emissions and invest in climate resilience, the numbers of people suffering harm will rise steeply, and many might even find themselves forcibly displaced both at home and abroad.

Rich nations like the United States (which is the leading historical contributor to global heat-trapping emissions) have the capacity and the responsibility to advance resilience at home and provide climate finance to help lower-income nations transition quickly to renewable energy and adapt to climate change. They also have a responsibility to help address climate loss and damage and displacement with a human rights-centered approach.

Hateful political rhetoric from President-elect Trump and his allies that demonizes and dehumanizes immigrants shows political leaders who are more interested in scoring cheap political points through fearmongering and fanning the flames of xenophobia, rather than acknowledging the basic humanity and incredible contributions of immigrants to our economy and our society.

This is not a new tactic. Across history, here in the United States and abroad, in uncertain economic times, extremists have often targeted immigrants and made harmful and deceptive claims blaming them for all the ills in society. Punching down, further marginalizing those who are fearful and may not have access to resources to defend themselves, is also a classic tactic of bullies and doesn’t solve the urgent problems facing our nation and our planet.

It’s up to all of us to stand up for the facts and stop allowing politicians to misuse the important issue of immigration policy to spew hateful lies as a convenient way to further their narrow interests. Mass detention and deportations will tear apart families, cause lasting trauma and harm, and set back health and education in immigrant communities especially for children, alongside undermining the the U.S. economy.  

We all know instinctively that leaving one’s familiar home and embarking on a dangerous journey to a faraway place, with very few resources and no guarantee of safety, is often an act of desperation—especially when bringing children. But for luck, this could be the plight of anyone in any country around the world.

Seeing our shared humanity and acting based on that principle is the best path forward on immigration and for our country of immigrants.

Scientists have a long-standing, and probably well-deserved, reputation as a jargon-prone bunch—and I am no exception (see my post on vapor pressure deficit, for one). Despite this reputation we actually use jargon to avoid confusion and be as precise as possible, ensuring our ideas are clearly understood. This seems straightforward enough for phrases like vapor pressure deficit, which needs to be distinguished from concepts like, for instance, relative humidity. But, scientists have also assigned specific meanings to otherwise ordinary words and phrases, that take on additional nuance and meaning when used in a scientific context.  

Take the word risk. Engineers might use it to mean the likelihood of a bridge collapsing. Economists might use it to mean a potential financial loss. An environmental scientist might use it to signal possible harm to a species of fish or vulnerable habitat. And in casual conversation, risk can mean a general concern or danger. Without specifying the context, the statement ‘The risks of addressing climate change are too large’ could justify almost any decision from reinforcing a bridge to withstand extreme heat to ignoring greenhouse gas emissions because of the financial losses that the fossil fuel industry would incur.  

In the case of the incoming administration, malicious actors use and create this confusion to exploit scientific illiteracy, justify inaction, and cultivate chaos, all of which cause harm to our communities, health and environment. This can take many forms: spreading disinformation, overemphasizing uncertainty, weaponizing ambiguity and nuance, or claiming that existing science is insufficient or incomplete, leading to harmful policies that distort science while maintaining a veneer of credibility. science while maintaining a veneer of credibility.  

In its first iteration, the Trump administration launched a coordinated assault on science and scientific integrity, and so far, all signs point to more of the same the second time around. To counter this, it’s critical to recognize and interrogate the language that will shape public discourse in the next administration. Here are three critical concepts that everyone who recognizes the essential value of science should know—and be prepared to defend against bad-faith attacks. 

What is “Best Available Science?” 

Best available science is the most reliable, valid, up-to-date, and relevant, empirical knowledge, and is referenced in laws, regulations, and court rulings, from the criteria for listing new species and developing recovery plans as part of the Endangered Species Act to the regulatory structure used in decision-making by the Food & Drug Administration for approvals and labels.  Science is dynamic and constantly evolving, meaning that the best available science builds on this on-going cycle of scientific inquiry as well as data and evidence from a range of sources. Inherently, best available science also relies on peer review, and draws on experts across disciplines.  

In the decision-making process of many government agencies, expert panels and advisory committees serve this critical function of analyzing existing evidence. These panels are composed of experienced researchers who are in the know about cutting edge research, the strengths and limitations of methodologies, and the latest debates on specific details. In the first Trump administration, we saw these panels and committees disbanded or downsized at the Environmental Protection Agency, Department of Energy, and Department of Health and Human Services, among others. Last year’s Supreme Court decision overturning the Chevron doctrine further endangered the use of best available science in decision making by shifting power from experts within governmental agencies to the judiciary.  

Further, best available science also uses specific language (and, in some cases, jargon) to accurately describe scientific findings, like using specific forest type designations when calculating wildfire emissions or describing the consequences of rule changes on different orders of waterways. The first Trump administration, in some cases, blocked scientists’ ability to do this by, for instance, removing a term such as “climate change” from certain government communications.  

Outside the US, the International Tribunal for the Law of the Sea reaffirmed the importance of using the best available science in their unanimous advisory opinion outlining countries’ obligations to prevent, reduce, and control pollution in the marine environment, highlighting the importance of scientists engaging across all facets of decision-making.  

Scientific Consensus Explained 

The term “scientific consensus” refers to concepts that have broad agreement among scientists, based on multiple lines of evidence and extensive peer-reviewed research. Examples of where there is scientific consensus include: evolution as the driver of life on earth, the Big Bang as the origin of the universe; and that human activity, particularly the burning of fossil fuels, is the primary driver of climate change.  This does not signal absolute proof, unanimous agreement, or the end of the scientific process, but consensus does provide a foundation from which scientists can continue to build knowledge to better protect our health, environment and communities.   

In the case of climate change, scientific consensus has led to countless new research questions about how we can adapt to protect our communities from rising seas, intensifying wildfires, and extreme heat. It has also painted a clear picture of how to mitigate future climate change and protect those who are most vulnerable—a fair and fast phase out of fossil fuels.   

The Role of Uncertainty in Building Trustworthy Science 

Quantifying and communicating uncertainty is a key part of any scientific endeavor, and one that scientists go to great lengths to understand and explain. The Intergovernmental Panel on Climate Change, widely regarded as the world’s leading body on climate science, has developed an entire system for describing scientific uncertainty and confidence in key findings throughout their reports.   

As I wrote in a blog last year: “Conversationally, uncertainty means something you don’t know — like I’m uncertain what I’m going to have for lunch. But scientifically, uncertainty means how well we know something— more like a confidence range and usually visualized with confidence intervals or error bars depending on the data (I’m 90-95% confident that I’ll be having beans for lunch).” 

When reading a scientific study, the absence of confidence ranges, explanations of methodologies, or other descriptions of how the researchers dealt with uncertainty is a major red flag. While those outside the scientific community might assume that the absence of uncertainty signals unwavering confidence in a finding, to other scientists it signals that the conclusions deserve particularly focused scrutiny.  

In the first Trump administration, we saw the Department of Interior overemphasize uncertainty around climate change in several of its reports, in direct opposition to the scientific consensus.  

Defending Science and Scientific Integrity 

As the second Trump administration looms, protecting rigorous research and scientific integrity is more critical than ever. When key scientific principles like transparency, accountability and continuous inquiry are compromised, as they were during Trump’s first term, the consequences ripple far beyond the scientific community, affecting public health, environmental sustainability, and the resilience of democratic institutions. The deliberate manipulation of scientific findings, whether by suppressing inconvenient truths, overemphasizing uncertainty, or distorting conclusions to fit a narrative, means that the best available science is absent from decision making.  

This erosion of public trust in science creates fertile ground for disinformation campaigns, stalls progress on urgent issues, and prioritizes political or economic agendas over the public good. During the first Trump administration, we saw these tactics in action, from the removal of climate change terminology from government reports to the systematic dismantling of advisory panels critical to applying the best available science to policy decisions.  

Defending science is not just the responsibility of scientists—it requires collective action by policymakers, educators, advocates, and the public. Together, we can ensure that science continues to serve the public good, guiding decision makers in a defensible and robust way toward a healthy, safe, and just future.  

L. Delta Merner, Lead Scientist for the Science Hub for Climate Litigation, contributed to this post. 

President-elect Trump has nominated Liberty Energy CEO Chris Wright to be US Energy Secretary, confirming the fossil fuel industry’s outsized and undue influence in shaping and implementing the Trump Administration’s agenda. Liberty is a leading producer of methane gas through fracking and according to ABC News, Wright donated almost $230,000 to the President-elect’s joint fundraising committee. The Senate Energy and Natural Resources Committee is expected to hold a hearing on Wright’s nomination tomorrow. 

In videos and Congressional testimony, Wright portrays himself as a “truth teller,” while falsely  claiming that climate scientists and renewable energy advocates are deceptive. These performances are textbook examples of disinformation, employing the exact tactics Mr. Wright decries.  

These are dangerous deceptions for someone potentially charged with leading the Department of Energy (DOE), an agency specifically tasked with informing the nation’s energy transition. Should Mr. Wright engage in such tactics during his confirmation hearing, Senators on the Energy and Natural Resources Committee must not allow him to get away with this ploy.  

The motivation to engage in disinformation comes when accurate information is threatening. Here are the facts. 

The human-caused, fossil fuel-driven, Climate Crisis is here. 

NASA’s Climate Evidence webpage leads with this headline: “There is unequivocal evidence that Earth is warming at an unprecedented rate.” The Fifth National Climate Assessment is equally clear: “Human activities are changing the climate . . . primarily because humans have burned and continue to burn fossil fuels for transportation and energy generation.” 

While Wright acknowledges the reality of climate change, he deliberately misrepresents climate data and research to downplay the seriousness of the problem and to undermine proven solutions including transitioning away from fossil fuels and accelerating the transition to clean energy. He adopts a purposefully shortsighted view when describing the impacts of burning fossil fuels on the world, focusing on profits over people.  

Yes, nations need energy for economic development, but that energy can and should come from clean resources, not dirty fossil fuels. Air and water pollution from fossil fuels is a major public health challenge and catastrophic climate impacts are setting back sustainable development and anti-poverty efforts, especially in lower income nations. The fact that fossil fuel companies have reaped enormous profits in the process is not an argument for more drilling. 

Wright’s frequent focus on the relatively recent past is purposely misleading. As NASA explains, over most of the last 800,000 years, until humans started burning fossil fuels, atmospheric CO2 concentrations basically never went below 180ppm and never went above 280ppm. That 100ppm difference, though, was the difference between glacial and interglacial periods. During glacial periods, much of the northern half of North America was covered in an ice sheet a mile thick. That .01% change in CO2 concentration is the difference between a planet humans can live on, and one we cannot. 

Primarily driven by the burning of fossil fuels, the CO2 concentration has increased to more than 420ppm. For roughly every 10ppm increase in CO2 concentrations, we see about 0.1C (nearly 0.2F) of warming. In the last sixty years, the amount of carbon dioxide in the atmosphere has grown 100 times faster than it did at the close of the last ice age. These are the numbers that must motivate our future energy policy, not the profits generated by the post-World War II oil boom.  

Climate change is making extreme weather more intense and more frequent. 

Leading independent global and U.S. scientific assessments, including from the Intergovernmental Panel on Climate Change (IPCC) and the National Climate Assessment, show that climate change is already having significant real-world impacts, and these will worsen as heat-trapping emissions rise. Advances in attribution science also show that climate change is contributing to worsening some types of extreme weather. For example, warmer air and oceans are contributing to more intense hurricanes, with record-breaking amounts of rain and rapidly intensifying windspeeds. 

Wright denies that people are experiencing the extreme weather that they are, in fact, experiencing, and misrepresents the IPCC in the process. In reality, the IPCC (a body comprised of thousands of experts from around the world who synthesize the most recent developments in climate science) writes in their Sixth Assessment Report, Chapter 11 of Working Group 1 on Weather and Climate Extreme Events in a Changing Climate: “It is an established fact that human-induced greenhouse gas emissions have led to an increased frequency and/or intensity of some weather and climate extremes since pre-industrial time, in particular for temperature extremes.”  

Real-world observations conducted by NOAA show the dramatic increase in billion-dollar extreme weather and climate-related disaster events in the US since 1980. Climate change has contributed to worsening several of these kinds of disasters—including floods, droughts, and wildfires—alongside growing development in risky areas.  

In 2024, at least 568 lives were lost in 27 separate disasters that each reported damages of $1 billion or more, with a total economic cost of at least $182.7 billion. 2025 is already off to a sobering start, with early estimates on the California wildfires ranging as high as $150 billion in damages. 

Wright’s false claims are shameful and should be particularly difficult to defend during hearings before a Committee which includes Senators Mazie Hirono of Hawaii, whose constituents suffered through the 2023 wildfires; Alex Padilla of California, whose constituents in Los Angeles are losing lives and homes as I write; and other lawmakers representing millions of Americans living through or recovering from disasters made worse by climate change. 

The US can meet its climate targets. 

Wright cites the persistent high price of oil, record profits for fossil fuel companies, and even his own personal wealth as evidence that a transition to renewable energy is not happening. His claim that a transition to a cleaner energy system is impossible because Wright and his allies have succeeded in delaying it is nonsense.  

UCS has documented that a transition to a cleaner energy system is feasible and would result in significant, long-term public health and economic benefits. By rapidly phasing out fossil fuels and transitioning to clean energy, the United States can meet its climate targets with lower near-term energy costs and only modest long-term costs. UCS modeling has found enormous economic, health, and climate benefits to transforming the energy system—including more than $800 billion in annual public health savings, and nearly $1.3 trillion in avoided climate damages by 2050. 

Clean, renewable energy contributes to reliability. 

In addition to dirty air and dirty water, the industry that made Wright wealthy also has a dirty secret: it’s unreliable. The recent failures of the gas system, including gas plants, under extreme weather conditions have led to rolling blackouts, with serious safety and health consequences for communities left without power during critical times of need. Looking closely at recent extreme winter weather events, a UCS analysis found that gas plants were disproportionately vulnerable to failure. By contrast, renewable energy sources can be more reliable during challenging weather conditions. 

Carbon pollution is pollution. 

Wright argues that rising CO2 levels are not dangerous. The EPA has found the current (or any increasing) mix of atmospheric concentrations of six greenhouse gases, including carbon dioxide, poses a threat to human health. The EPA engaged in a public process that took more than two years and included exhaustive review of the scientific literature to reach this finding. And while Wright claims labelling CO2 as pollution is a “marketing” tactic, it was the U.S. Supreme Court, not the wind or solar industries, that forced the EPA to act on the basis of existing law, the Clean Air Act. 

Wind and solar are clean energy. 

While all energy sources have impacts, wind and solar are much cleaner than fossil fuels. Wright’s frequent, narrow focus on the use of fossil fuels in the manufacturing and construction of wind turbines and solar panels is highly misleading and doesn’t tell the whole story.  

The heat-trapping emissions from these activities are minor compared to the lifecycle emissions from the combustion of fossil fuels. In fact, overall lifecycle greenhouse gas emissions from generating electricity from methane gas and coal are 11-23 times higher than solar and 37-77 higher than wind, respectively, according to data from the National Renewable Energy Laboratory (NREL). And unlike fossil fuels, electricity generated by wind and solar does not use water or produce any emissions or wastes that can contaminate the air, land, or waterways. 

Defining the energy produced by wind, solar, and other renewable sources as “clean” is a factual description of what that energy does to our world when we use it, compared to burning dirty coal, oil, and methane. It is obvious why someone who has made a fortune in the business of dirty energy might not like that label, but if the dirty shoe fits . . .   

The Questions Senators Need to Ask. 

Again, the motivation to engage in disinformation comes when accurate information is threatening. For example, when people say, “this is not about the money,” you can be sure it is absolutely about the money. 

A Senate confirmation hearing should provide Senators and the public an accurate picture of the nominees’ views and fitness for public service. President-elect Trump has selected Chris Wright for the Department of Energy because he will double down on the production and use of the same old, dirty energy resources that have made him wealthy; wealth that Wright and other industry figures have used to fund the Trump campaign. (My colleagues have also shared insightful advice that should guide Senators’ approach in evaluating these nominees.) 

Rather than engaging in deceptive claims designed to turn facts on their heads, Wright should simply be honest about his views and let the Senate—and the public—decide whether he is the right person to set US energy policy for the next four years.  

As the climate crisis deepens, so does the urgency to hold fossil fuel companies accountable for decades of deception. Governments representing more than a quarter of the US population have filed lawsuits against major corporations including ExxonMobil, Chevron, Shell, and BP, seeking justice for the harm caused by their lies about the dangers of their products. And especially on the cusp of a new Presidential administration that has vowed to support the fossil fuel industry and nominated appointees with a blatant disregard for science, the courts will become an integral arena to advance climate justice—and a pivotal space for scientists of all disciplines to make an impact. 

These lawsuits hinge on the best available science to uncover the truth and inform the courts. UCS is already working with social scientists and economists, civil engineers and health practitioners who can bring extensive expertise to multi-faceted litigation. As the fossil fuel industry spares no expense to obscure these truths, the work of scientists who engage with climate litigation is increasingly vital. They bring clarity, evidence, and credibility to a high-stakes fight where lives—and the planet—are on the line. 

To help scientists of all disciplines who are thinking about getting engaged, but might not know where to start, I turned to Delta Merner, Lead Scientist for UCS’s Science Hub for Climate Litigation. Merner’s research and expertise has informed climate litigation across the globe, as she connects legal teams with technical experts and leads trainings for scientists working at the intersection of climate science and law.  

AAS: What would you say to scientists who feel they don’t have the expertise or understanding to participate in climate litigation?  

DM: In many ways, climate litigation isn’t actually that different from the work scientists are used to doing. At its core, we’re still asking robust questions, conducting thorough research to assess those questions, and drafting compelling documents to communicate our findings. The fundamental process remains the same—it’s just a different format and audience. 

In some ways, for example, my PhD defense did prepare me with skills that translate well to the courtroom. After all, you quickly learn to stay calm and back up your claims when you have to stand in a room full of brilliant, critical people ready to poke holes in your every word. 

In both cases, you’re making a claim, presenting evidence, and responding to questions or criticism. The key difference is the audience. Instead of speaking to other scientists, you’re addressing a legal community that operates with its own rules of argumentation, unique citation methods, and a distinct language for making claims. 

So, while the tools and processes are familiar, adapting to this new audience requires an additional layer of thoughtfulness. You’re not just presenting facts— you’re translating complex scientific evidence into a form that meets the legal system’s standards of argumentation, while upholding scientific rigor and independence. That intersection between science and law is what makes this work so fascinating and impactful.

AAS: What was that transition into the legal arena like for you? Who did you look to for guidance and to learn from?  

DM: My first time testifying in court was during my PhD program, and honestly, I had very little guidance. I didn’t fully understand how different it would be to communicate my research to a legal audience. I knew my research inside and out, and I thought that would be enough—but it quickly became clear that presenting in this context is a skill in itself. It requires not only expertise in your subject matter but also the ability to convey that knowledge in a way that resonates with the specific needs and expectations of the court. 

This realization pushed me to seek guidance and learn from others. There are experts who have been doing this work for years, and generally speaking, science has been presented in US courts for a long time. For me, working through the courts felt like an opportunity to apply my research to create real-world change, but to do that effectively, I needed to broaden my perspective. I’ve learned a great deal from science communicators, organizers, researchers, and litigators who understand how to bridge the gap between science and law. Each has contributed to shaping how I approach this work and helped me find my voice in the courtroom.  

Historically, however, it can be difficult to find spaces to meet and work with others in this field–that’s why UCS started the Science Hub for Climate Litigation. The Science Hub for Climate Litigation has developed a valuable community of peers where scientists, communicators, and legal experts can learn from each other—whether it’s gaining insights from those with courtroom experience or collaborating to refine how we present complex evidence to drive meaningful change. 

AAS: UCS scientists often provide their scientific expertise to help inform policies. You’ve said that informing legal cases is just as critical as informing the formation of policy. Can you talk a little more about that? 

DM: That’s a great question, and it’s one that gets to the heart of our work. At UCS, we see climate litigation, informed by science, as one of the most impactful tools we have to address climate change—and the evidence is clear that it’s working. The last IPCC report stated that climate-related litigation “has influenced the outcome and ambition of climate governance.” It also highlighted that “outside the formal climate policy processes, climate litigation is an important arena for various actors to confront and interact over how climate change should be governed.” In short, climate litigation is actively shaping climate action today. 

Scientists have a critical role to play in this space. We can conduct robust, timely, and litigation-relevant research. We can help inform the courts through amicus briefs or other legal interventions designed to provide judges with the evidence they need to make informed decisions. And we can even step into the courtroom as expert witnesses. But engaging in litigation isn’t necessarily intuitive or straightforward for most scientists. That’s where the Science Hub for Climate Litigation comes in.  

The Science Hub focuses on four key areas: catalyzing legally relevant scientific research, expanding the community of scientists and legal experts informing litigation, making robust science widely accessible, and connecting legal teams with experts. Together, these efforts create a pathway for scientists to bring their expertise into the legal arena and make a tangible impact on climate action. 

AAS: First and foremost, like many of our readers, you are a researcher. Can you tell us a little more about those existing gaps in current scientific research that, if addressed, could further support climate litigation? 

DM: As a researcher, I see significant opportunities for science to further inform climate litigation by addressing critical gaps. Our recent report on research areas for climate litigation highlights several key needs. For instance, attribution science remains a priority—establishing causal links between emissions, climate impacts, and specific events is essential for many cases. However, there’s a pressing need to expand this research to underrepresented regions, particularly in the Global South, where baseline data is often lacking. Developing new methods to suit these contexts can help ensure justice is accessible to all communities impacted by climate change. 

We also identified the connections between climate change and human health as another priority. Cases that focus on health impacts, such as those related to extreme heat or air quality, require more robust data, particularly for vulnerable populations like children, older adults, and pregnant people. Similarly, economic research that quantifies the costs of climate impacts and the benefits of mitigation is vital for informing remedies in legal cases. Addressing these issues demonstrates how expertise from diverse disciplines—whether in public health, economics, or social science—can play an important role to inform climate litigation. You don’t need to be a climate scientist to make a meaningful impact. 

Beyond these priorities, our work highlights strategic areas like disinformation and greenwashing, emissions accounting, and fair share analysis for corporate and national accountability. Each of these areas presents opportunities for science to fill evidence gaps that are critical to informing litigation.  

By addressing these gaps, scientists can play a role in informing the evolving landscape of climate litigation and ensure that courts have the best available science to inform their decisions. 

AAS: In a recent blog post, you mentioned the opportunities to expand the scope of climate litigation in 2025. Could you elaborate on the stakes of what’s on the docket this year? 

DM: This year’s climate litigation docket has high stakes, with cases that could set major precedents for how we address the climate crisis. On the international stage, the International Court of Justice (ICJ) is working on an advisory opinion to clarify what responsibilities countries have under international law to combat climate change. (UCS actually helped a number of states in the Global South to prepare draft their written submissions.) While this opinion won’t be legally binding, it could influence future cases and push governments to take stronger climate action. Similarly, the Inter-American Court of Human Rights is considering how climate change disproportionately affects vulnerable populations, linking climate action to fundamental human rights. 

In the US, more than a quarter of people now live in places that are suing  major fossil fuel corporations for deceiving people about climate change and for the damage they knew their oil, gas, and coal products would cause. These cases aim to hold companies accountable for the disinformation that has blocked climate action and slowed the transition to clean energy. ExxonMobil and other major fossil fuel corporations have employed numerous procedural tactics to delay progress of these lawsuits (some of which have been ongoing for more than seven years), preventing them from being heard in courtrooms across the country. 

We’re also seeing more lawsuits following climate-related disasters, like the Maui wildfires and severe flooding in North Carolina. These cases often focus on holding governments or companies accountable for not doing enough to prepare for foreseeable climate risks, like stronger storms or longer droughts. They highlight the very real human and financial costs of climate inaction and aim to drive systemic change. 

This wave of litigation shows that courts are becoming a critical arena for climate action, especially as political systems struggle to keep up with the urgency of the crisis. By combining evidence from science, law, and lived experience, these cases have the power to bring about accountability and push for meaningful solutions. 

AAS: And I’ll close with this: it’s a new year, a fresh start, and folks are making resolutions. What is something concrete that you’re working on?  

DM: This year, I’m focusing on communicating the value and potential impact of scientists informing climate litigation. It’s crucial for scientists to understand that this work is about ensuring that courts have access to accurate, robust evidence to make informed decisions. Upholding the integrity of our research while making it actionable is essential to bridging the gap between science and justice. 

At the same time, I want to increase engagement among scientists to help them recognize the critical role they can play in legal processes. Whether it’s providing expert testimony, contributing to amicus briefs, or making their findings more accessible to legal teams, there are so many ways to contribute. By supporting scientists in these efforts, we can create a stronger connection between science and the legal system, and empower courts to drive meaningful change.

While deaths and destruction are mounting and tens of thousands flee a devastating inferno in Los Angeles, the President-Elect has used the catastrophic wildfires to spread misinformation, offer false solutions, and disrespect the suffering of people and the hard work of first responders. Here, we provide the facts and avoid the fiction.  

Fact 1: reservoirs are full

Due to a relatively wet winter in Northern California, almost every reservoir in Southern California is at or above its historical average. There is ample water available in reservoirs to fight fires. The challenge is getting the water from the reservoir to the fire fighters. 

Fact 2: California’s water system is a patchwork  

California, like most states, has thousands of water systems. Federal, state, municipal, regional, and private water systems co-exist. Some are connected to each other, some aren’t. What happens hundreds of miles away in one system does not necessarily have an impact on your local supply. In other words, decisions about federal water in one part of the state don’t automatically increase or decrease how much water your local utility has available.  

Fact 3: City water systems are not designed to suppress massive wildfires 

Cities build infrastructure to meet demands without being unnecessarily expensive. For example, water systems are designed for the capacity to deliver enough water to serve customers’ normal household water needs and to provide a limited amount of “fire flow,” or excess capacity for fire suppression. During the initial hours of the Palisades fire, the LA Department of Water and Power experienced unprecedented water demand — four times the normal water use for 15 hours straight. This incredibly high, sustained level of water demand outstripped the ability of the system to keep the water flowing. It was water use, not water supply, that led to a temporary shortage for fire flows.   

Fact 4: Fire fighters often rely on air support to contain rapidly burning fires 

The Palisades fire ignited during some of the worst Santa Ana winds, gusting at more than100 miles per hour at times. This made air support dangerous and unreliable during the critical first few days of the fire, placing a larger burden on the municipal water system.   

Fact: Wildfires are worsening due to climate change 

At a basic level, the connection between wildfires and water is intuitive: fires start more easily, burn more intensely, and spread faster when it’s dry and hot. That’s bad news, because climate change is increasing temperatures and the risk of drought in many regions. It’s particularly pronounced in the western United States, where heatwaves and megadroughts are priming us for wildfire. In fact, western landscapes are now roughly 50 percent drier due to climate change. 

Fact: Fossil fuel companies are privatizing profit and socializing costs of climate change 

Emissions from the products of fossil fuel companies and cement manufacturers have fundamentally reshaped the climate of western North America and left behind a scarred, charred landscape in which people, communities, and the ecosystems that enable their existence are suffering. To-date, taxpayers and victims have been footing the bill for worsening wildfires.  

However, UCS’s new analysis quantifies the contribution of fossil fuel companies to fire conditions. Federal, state, and local governments have the power to hold fossil fuel companies accountable for the costs of climate change impacts. And they should. 

President-elect Donald Trump seems hell-bent on filling his cabinet with anti-science extremists, including climate science deniers. While these nominations are dangerous, what’s even more disturbing is the opening they create for fossil fuel corporations that have masterminded climate deception campaigns to regain social license. ExxonMobil, Shell, and trade associations like the American Petroleum Institute now profess to accept climate science—even as they exacerbate the crisis by continuing to expand fossil fuel production and kick the climate action can down the road with greenwashing and doublespeak.

In a cynical effort to please climate-conscious investors, ExxonMobil Chair and CEO Darren Woods may choose to keep climate science deniers like DOE nominee Chris Wright at arm’s length. But with global temperatures rising, the carbon budget dwindling, and climate-driven disasters affecting people and communities around the world, we cannot afford to accept ExxonMobil, Shell, or other major fossil fuel corporations as the lesser evil—or even worse, as integral to climate solutions.

Trump reignites overt climate denial

During his campaign, Trump sought $1 billion from oil and gas CEOs in exchange for a pledge to reverse environmental regulations and prevent new policies from being enacted. Since Trump’s election to a second term, fossil fuel industry interests have published their wish lists—and patrons have been rewarded with appointments to key posts in the administration. And we’ve already seen a resurgence of outright climate science denial.

Chris Wright, Trump’s nominee for Energy Secretary, has denied the well-established connection between climate change and extreme weather events. Liberty Energy, the fracking corporation he heads, describes its Environment, Social, and Governance (ESG) focus as delivering secure, reliable, affordable access to energy. Its ESG report downplays the urgency of the climate crisis and misrepresents the findings of the Intergovernmental Panel on Climate Change. This deliberate distortion of ESG builds on years of anti-ESG efforts by far-right activists including Vivek Ramaswamy, appointed by Trump to partner with fellow billionaire Elon Musk in weakening federal regulations and slashing government spending (notably, oil and gas subsidies are not on the chopping block).

Congressional allies pump up oil and gas

Meanwhile, on Capitol Hill, the Republican-led House Judiciary Committee has continued its attack on ESG investing, most recently in an unhinged report that rallies behind ExxonMobil against an alleged “cartel” of climate-conscious investors. The committee seems to be living in an alternate reality in which investors using market tools to influence corporate strategy is somehow illicit, while fossil fuel companies colluding to fix prices is not. The Judiciary Committee’s upside-down world is detached from reality, ignoring both record high US oil and gas production under the Biden administration and the fact that renewables continue to be cheaper than fossil energy.

Representative Jim Jordan’s Judiciary Committee embraces anti-climate positions that ExxonMobil itself long ago abandoned, alleging that commitments to reach net zero global warming emissions by 2050 are part of a “left-wing climate agenda.” Does ExxonMobil, the nation’s largest energy corporation, really need protection by a paternalistic Congress against powerful bullying investors? More likely, ExxonMobil recognizes that to compete in the global market, it must convince investors that it is taking action to reduce heat-trapping emissions and limit the worst effects of climate change. (As my colleague Dr. Carly Phillips has shown, ExxonMobil’s recent climate reports are misleading at best, dishonest at worst—textbook examples of greenwashing).

Major fossil fuel corporations lit the fuse decades ago

Climate change denial is no accident. It was plotted decades ago by the fossil fuel industry—for example, in an infamous 1998 memo by a task force of the American Petroleum Institute, which said that “Victory will be achieved when average citizens understand (recognize) ‘uncertainties’ in climate science.” As my UCS colleagues and I wrote in the Climate Deception Dossiers, this plan was eerily reminiscent of the tobacco industry’s strategy, succinctly described in an internal corporate memo as, “Doubt is our product…”

The fossil fuel industry’s concerted disinformation campaign has been so successful that ExxonMobil, one of the ringleaders, can now claim to accept climate science while cronies like Chris Wright and Jim Jordan continue to stoke doubt.

Fossil fuel interests have been in Trump’s inner circle from the jump

In 2016, President Trump tapped ExxonMobil Chair and CEO Rex Tillerson as his Secretary of State. As I wrote at the time, Tillerson was an inappropriate and deeply troubling pick for the post, for countless reasons—here were five of the most distressing ones.

One of those reasons was the ways Tillerson doubted and downplayed climate change. And after his service in the Trump administration, the Wall Street Journal revealed new evidence that Tillerson had dismissed the Paris Agreement’s goal of keeping global temperature increase to well below 2 degrees Celsius above preindustrial levels (and striving to limit it to 1.5 degrees Celsius) as “something magical.” Worse still, just months before the agreement was signed, Tillerson asked, “Who is to say 2.5 is not good enough?”

Climate scientists, backed by robust research, say so. The IPCC Special Report on Global Warming of 1.5° C found that surpassing 2 degrees C of warming would significantly increase the frequency and severity of climate impacts, including extreme weather events, biodiversity loss, and threats to human health and livelihoods. However, limiting warming to 1.5 degrees C, could substantially reduce these risks, highlighting the critical importance of ambitious global climate action.

In 2017, Tillerson said he disagreed with President Trump’s decision to withdraw the US from the Paris Agreement. He was fired from his position in the administration just nine months later.

ExxonMobil hides behind extremists

ExxonMobil is staking out a different position in the second Trump administration.

2024 wrapped up as the hottest year on record, with warming temporarily reaching 1.5 C. Unlike Tillerson or Trump, current ExxonMobil Chair and CEO Darren Woods professes to support the Paris Agreement. However, the corporation pushes technological “solutions” that can’t bend the emissions curve steeply downward in the critical period between now and 2030.

In December, ExxonMobil released its plan to 2030, which calls for an 18% increase in oil and gas production, thanks largely to growth in the Permian Basin (after last year’s acquisition of Pioneer) and offshore Guyana. Woods bragged about reducing ExxonMobil’s upstream (exploration and production) emissions intensity by 20% between 2016 and 2023—and says it is aiming to cut emissions intensity 40-50% by 2050.

However, upstream emissions intensity measures emissions per unit of production—and excludes emissions from burning oil and gas, which constitute roughly 85 percent of the heat-trapping emissions attributable to ExxonMobil. So, if production is increasing—as ExxonMobil’s is—absolute emissions will continue to climb even if upstream emissions intensity significantly decreases.

The corporation says it is pursuing “up to $30 billion in lower-emissions investment opportunities”—which for ExxonMobil means carbon capture and storage (CCS), hydrogen, and lithium. Among other projects, ExxonMobil’s Low Carbon Solutions business is developing a Texas plant to produce hydrogen from fossil gas (if the tax credit included in the Inflation Reduction Act survives) and a gas-fired power plant to support a data center. (Read more about how data centers’ rapidly growing energy use is changing electricity supply and demand—and what it means for energy infrastructure planning—in this blog by my UCS colleague Mike Jacobs).

Fossil fuel lobbyists grab seats at the table

ExxonMobil’s Woods was one of more than 1,770 fossil fuel industry lobbyists granted access to the annual UN climate negotiations (COP29) in Baku, Azerbaijan. The heads of Aramco, BP, and TotalEnergies were also registered to participate as guests of the host country.

Woods made headlines when he discouraged US President-elect Trump from withdrawing the United States from the Paris Agreement. Although some media outlets credited Woods with supporting climate policy and pushing back against Trump’s anti-climate agenda, what he actually said was, “The way you influence things is to participate, not to exit.” What I see in the oil and gas industry’s participation at COPs is not a commitment to climate action, but the determination—and access—to interfere with a fair, fast, and funded phaseout of fossil fuels by the international community.

What to watch out for in 2025

As 2025 begins, the challenges for climate advocates are at least threefold: 1) mobilizing fierce opposition and marginalizing climate science deniers who secure positions of power in Congress or the administration; 2) inoculating state, federal, and international policymakers against deception and greenwashing by ExxonMobil and other major fossil fuel corporations; and 3) defending and expanding the use of ESG investment strategies against bad-faith Congressional “oversight.”

With federal climate and clean energy policies likely to be stalled or rolled back, climate litigation is a key arena for progress in the United States. Preserving access to justice through the courts will be essential, in the face of veiled threats against climate-related litigation in Project 2025 and Trump’s promise to stop climate accountability litigation against the oil and gas industry.

The fossil fuel industry will attempt to cash in on its political influence in the United States by advancing deregulation, facilitating increased oil and gas production on federal lands and waters, expanding subsidies and other giveaways, blocking mandatory climate disclosure, evading liability for climate damages and corporate misconduct, and stoking political and legal attacks against activists and organizers. As President-elect Trump opens the floodgates to all kinds of disinformation—including climate science denial—some pro-fossil forces will fight climate and clean energy policies directly. But others will more stealthily seek to delay and undermine the transition away from fossil fuels, claiming to support climate action while defining “climate solutions” in their narrow short-term interests. These efforts to regain social license by those most responsible for the climate crisis are particularly insidious.

Both approaches—and the actors who employ them—endanger our health, environment, energy security, human rights, and democracy. Even as we steel ourselves to refute a barrage of lies from top officials in the Trump administration and Congress, we must resist compromising with leaders of an industry that has deceived the public and policymakers for decades, evaded accountability for the harm it has caused, continues to obstruct the urgent transition to renewable energy, and has not earned the public’s trust.

The year 2023 was by far the warmest in Earth’s recorded history, and perhaps in the past 100,000 years, shattering the previous record set in 2016 by 0.27°C (0.49°F). According to recent data from NOAA’s National Center for Environmental Information, 2024 is likely to be even warmer than 2023.  

Scientists are sounding the alarm because this warming is shockingly big—bigger than what we would have expected given the long-term warming trend from fossil fuel-caused climate change. But why were 2023 and 2024 so warm? 

The reason why 2016 was so warm was because of a strong El Niño event—a naturally-occurring cycle in the Earth’s climate system—which typically leads to a spike in Earth’s global-mean temperature. In that year, El Niño added to the increased warming caused by the build-up of heat-trapping emissions in the atmosphere, leading to that record-breaking heat. 

This is why 2023 and 2024 are so alarming: El Niño was only moderately strong (contributing a small amount of warming) in 2023 and was in a neutral state for most of 2024 (contributing almost no warming), so we cannot attribute the record-breaking warmth of  2023 and 2024 to El Niño like we did in 2016, and we definitely should not be shattering heat records under a neutral state El Niño. In other words, 2023 and 2024 have been much hotter than scientists’ predictions. 

What could be a potential explanation for the record-breaking warmth? This question was a focus at the 2024 annual American Geophysical Union (AGU) meeting in Washington, D.C., where 30,000-plus scientists gathered to present their latest research. The two leading theories to explain the record-breaking warmth are a reduction in tiny particles in the atmosphere called aerosols due to shipping fuel regulations that reduced sulfur oxide (SOx) emissions, or decreasing cloud cover. Before we get to those two likely culprits, let’s talk about albedo. 

What is albedo?

A concept that’s important in both of these theories is planetary albedo. Albedo is the total reflection of incoming solar radiation by Earth. This reflection is done partially by lighter-colored surfaces such as ice sheets and ice shelves, clouds, deserts, and also by aerosols. Think of walking outside on a sunny day after a snowstorm or in a desert; the sun’s rays are reflected by the light surface, making it harder to see. These solar rays are normally reflected out to space. 

The planet typically reflects about 30% of incoming solar radiation, but this number can change slightly depending on how much snow- or ice-cover there is, on the amount of cloud cover, or on how many aerosols are in the atmosphere (remember, these are tiny atmospheric particles that reflect light). Humans have a direct effect on albedo through emitting industrial aerosols such as sulfates, which accumulate in the atmosphere due to the burning of fossil fuels. 

You might be thinking, “if the burning of fossil fuels increases Earth’s albedo due to additional aerosols in the atmosphere, shouldn’t this offset any impact from the effects of increased heat-trapping emissions like carbon dioxide?” It’s a great question, but the warming effect from heat-trapping gases far outweighs the cooling effect from industrial aerosols. 

Reduction in aerosols leads to albedo decrease 

A popular theory that could explain why the past two years have been so warm has to do with a change in aerosol emissions due to new shipping fuel regulations aimed at helping to address pollution that harms health and the environment. In 2020, the International Maritime Organization (IMO) reduced the limit on the amount of sulfur in ships’ fuel oil, which then led to a reduction in sulphur dioxide and particulate matter emissions which form aerosols in the atmosphere.  

According to two recent studies, this reduction in aerosols may have led to a spike in the global-mean temperature. How? As industrial aerosols decreased due to this new regulation, particularly over the North Atlantic Ocean, the planetary albedo slightly decreased, which means that more incoming solar radiation was absorbed by the planet rather than reflected. 

However, another study found that the effect of additional industrial aerosols in the atmosphere would only affect global-mean temperature by a couple hundredths of a degree, rather than the 0.27°C observed in 2023. 

Of course, continuing to strengthen public health-based standards to cut harmful air pollution from burning fossil fuels, including sulphur dioxide and particulate matter, is essential and lifesaving. Further scientific work is underway to help advance our understanding of how and how much this contributes to changes in industrial aerosols and how that may be influencing the rate of warming. Meanwhile, sharply cutting our use of fossil fuels is the best way to limit carbon dioxide (CO2) emissions, the primary driver of climate change.  

Diminishing cloud cover due to warming creates more warming 

A study released just last month, and another preprint of a study presented at AGU, provide a different explanation for the spike in global-mean temperature: clouds. In this case, the authors of both papers argue that a decrease in cloud cover led to the decrease in planetary albedo.  

Over the last few decades, there has been an observed decrease in total planetary cloud cover, especially over the North Atlantic Ocean off the Northeast US coast. Here, low-level cloud cover has decreased drastically, mostly related to an increase in ocean surface temperature.  

The decrease in low-level cloud cover due to warming ocean surfaces is particularly alarming because the process could be the manifestation of a feedback associated with global warming: as the oceans warm, low-level cloud cover decreases, which results in a lower planetary albedo and thus a faster warming world. 

Ocean surface temperatures in the North Atlantic could also be warming so much due to a weakening of the Atlantic Meridional Overturning Circulation (AMOC), which I blogged about in November. While ocean surface temperatures are increasing globally due to fossil fuel-caused climate change, they are warming even faster off the US Northeast coast, which could be the result of the AMOC slowing down and pooling warm water in the region. 

Important questions are still being sorted out 

Climate scientists are still trying to figure out what exactly made 2023 and 2024 so warm. We discussed some potential reasons that could explain the spike in warming, but the details haven’t been ironed out quite yet. 

What’s interesting is that the sudden warming could also be due to a combination of the two theories.

Did you know that in order for water droplets to form in the atmosphere to create clouds, they need a tiny particle to condense onto? These tiny particles are called cloud condensation nuclei (CCN), and one type of CCN is industrial aerosols such as sulfates. After the IMO lowered sulfur in shipping fuel oil, less sulfate aerosols in the atmosphere could have resulted in less CCN available for cloud droplets to form, resulting in a lower planetary albedo. 

To perhaps add another layer to everything, during my PhD research, I studied how different patterns of ocean surface temperature affect the rate of global warming. For example, if the West Pacific warms more than the rest of the world, then the planet will actually warm at a slower rate than if that warming was distributed evenly across the ocean’s surface. 

We found that the most likely ocean surface pattern of warming in the near future, which is currently developing, will result in a rapidly warming planet. This could very well be a piece of the puzzle as to why 2023 and 2024 were so warm. 

Scientists continue to sound the alarm 

The additional warming in 2023 and 2024 adds a layer of complexity to fossil fuel-caused climate change (and not the kind of complexity we want, given that the planet seems to be warming more rapidly than before). These two ideas from the science community are still being ironed out, and it will take some more time to understand exactly what caused this spike in global-mean temperature. 

One thing is for sure though: the planet is warming mainly due to increased heat-trapping emissions in Earth’s atmosphere from the burning of fossil fuels. The only way to slow down warming is by reducing said emissions through a fast and fair transition to clean, renewable energy. 

Senators have the herculean task of ensuring that our nation’s future is in the hands of appropriate leaders. Through the Senate confirmation process, they are responsible for vetting nominees for the most senior leadership positions in federal agencies.

There are more than 1,300 positions requiring Senate confirmation, many of whom will shape policies and programs that rely heavily on scientific expertise and knowledge. These are positions critical to protecting public health and the environment, keeping the nation’s food and drug supplies safe, and advancing US interests. Senators need to ensure that nominees are the right fit for the job and avoid costly mistakes that risk human lives and the health of our planet.

Some positions you may have heard of include the Under Secretary for Nuclear Security for the Department of Energy; the Under Secretary of Defense for Research and Engineering for the Department of Defense; Administrators for the Environmental Protection Agency (EPA), the Department of Transportation, the National Aeronautics and Space Administration, and the National Oceanic and Atmospheric Administration (NOAA); and Directors for the National Institutes of Health and the National Science Foundation.

My colleagues have raised concerns already about President-elect Trump’s picks to lead the EPA, the Department of Housing and Urban Development, and the Department of Justice, and why the new NOAA administrator must understand and advocate for science.

Appointees’ Science Savvy Matters

Why should we care that presidential appointees know how to understand and apply science appropriately in their decision making? One key reason is that President-elect Trump’s scientific understanding does not inspire confidence, so senators should at least make sure the people running the executive branch have a firm grounding in science.

Perhaps you remember “Sharpiegate” in 2019, when then-President Trump doctored the forecast path of Hurricane Dorian with a black Sharpie maker. He altered the official weather forecast to suggest the hurricane might strike Alabama. Despite corrections from the National Weather Service, President Trump continued to insist he was correct, creating public confusion about who needed to evacuate and where emergency response resources would be needed. This put American lives and livelihoods at risk and wasted taxpayer dollars.

Senators evaluating nominees who will oversee policies and programs deeply rooted in science should vet them for the following:

1. Strong scientific background. Does the nominee know their quarks from their quasars or their atoms from their amino acids? Do they consult bona fide experts in the subject matter?  Do they check for people posing as experts who are really purveyors of disinformation or misinformation?  Do they check the potential conflicts of interests of the experts they consult? A strong grasp of technical material is essential for making rules that keep us safe, for instance from environmental contaminants such as the carcinogenic gas ethylene oxide.
2. Analytic skills. The nominee should be able to analyze complex data, interpret scientific research, and apply findings to policy or program development and implementation. Maximizing electric grid reliability, for instance, requires our leaders to integrate data about the costs and benefits of energy storage options considering multiple factors such as local growth projections, increased electricity demand, solar and wind profiles over time, energy generation by fossil gas technologies, and policy incentive impacts.
3. Critical thinking. Look for someone who questions assumptions, even questions their questions about the assumptions! A nominee should be aware of the heuristics and biases that challenge all human cognition and set up strategies to address these limitations. For instance, biases that block funding for all federal research that uses fetal tissue put at risk advancements in vaccines, transplants, and treatment of degenerative diseases like Parkinson’s.
4. Communication skills. The nominee must be able to communicate complex scientific concepts so clearly that your grandma (and even the President) will understand. For instance, explaining nuclear toxicology concepts is important for helping the public understand why and how to avoid radiation exposure.
5. Problem-solving abilities: They should be adept at identifying problems and developing innovative, science-based solutions. There will be no shortage of opportunities to test this skill, especially during periods such as “danger season,” the time of year when climate change impacts like hurricanes, extreme heat, and wildfires peak and collide with one another.
6. Ethical judgment: Senators must ensure the nominee has a strong sense of scientific integrity and intellectual honesty, as they will be making decisions that can significantly impact public health and safety. Why? Because lives and livelihoods are at risk. Lessons from prior administrations and examples of anti-science actions during the first Trump administration are well-documented by UCS.
7. Collaboration and teamwork: The nominee should play well with others, including scientists, policymakers, and members of the public who are directly or indirectly affected by their programs. The nominee has a particular responsibility to respect and defend the federal scientific workforce because these experts are essential for keeping people and our planet safe and healthy.
8. Adaptability: Having the ability to adapt to new scientific developments and changing policy landscapes is a must because science evolves, as does the social-ecological system scientists are working within. Nominees will need to integrate the latest science with other considerations as they decide on the optimal solutions to complex problems.
9. Leadership skills: This includes the ability to inspire and guide teams, and to make tough decisions when necessary. The captain of the ship needs to navigate through a sea of scientific jargon, uncertain evidence, and different assumptions and values. Dialogue on the New Strategic Arms Reduction Treaty is just one example issue where leadership plays a critical role in global stability, in this case in preventing a runaway arms race.
10. Passion for public service: A genuine commitment to using science to benefit society and improve public policies is a must. Taxpayer dollars will pay this nominee’s salary, so I want them acting in my best interest.

Some of these might seem like “no duh” suggestions. But we don’t have to look too far back to see when a lack of scientific expertise, a lack of respect for scientific methods, or a predilection for ignoring science resulted in preventable death and disease, or profound harm to our planet. For senators who find science daunting, this simple rubric can help to highlight who should be trusted to lead federal departments and agencies that rely on science to address the important concerns and needs of their constituents.

As 2024 winds down, with its parade of climate-and extreme weather-fueled disasters, people across the nation are feeling the sharp pinch of rising insurance premiums and dropped policies. There are other factors at play here—including growing development in flood-prone and wildfire-prone areas and fundamental inequities and information gaps in the insurance market—but all of that is being exacerbated by worsening flooding, wildfires and intensified storms. Policymakers and regulators must act quickly because the market is not going to solve this problem on its own, and it’s definitely not going to do it in a way that protects low- and middle-income people. 

Please see earlier blogposts I’ve written on this topic to learn more.  

More data transparency is urgently needed 

Despite the many headlines and heart-breaking stories about the impact of high insurance costs and dropped policies, there’s a lack of publicly available, granular data on where and how much premiums are increasing and why.  

Earlier this year, the US Department of the Treasury’s Federal Insurance Office (FIO) and the National Association of Insurance Commissioners (NAIC) announced a first-ever data call to assess how climate risks were affecting the insurance market. This is a voluntary effort and some states, including Florida, Texas and Louisiana, have already signaled they will not participate. That’s a problem because these are also states where consumers have experienced sky-rocketing rate increases and insurers dropping policies or even exiting the market entirely—and they are highly exposed to climate risks. 

According to an annual report from the Financial Stability Oversight Council (FSOC), “The data call required participating insurers to submit ZIP Code-level data on premiums, policies, claims, losses, limits, deductibles, non-renewals, and coverage types for the ZIP Codes in which they operate nationwide. State insurance regulators sought more than 70 data points. An anonymized subset of the data was shared with FIO.”  

Yet, none of that data has been shared publicly. That’s why UCS has joined in signing a letter from a group of organizations, calling on FIO to release the data so it’s available for local planners, policymakers, decisionmakers, scientists and community-based organizations to have a better understanding of how best to address this rapidly growing problem.  

Private insurers are holding a lot of proprietary data that regulators and the general public do not have access to. This creates a gap in information—an information asymmetry—that can prevent people from making informed decisions and prevent the market from functioning well. A lack of freely available, localized information about climate risks and projections is also part of the challenge for many communities and homeowners.  

Congressional oversight is needed 

The insurance crisis is now a nationwide problem, spilling into parts of the country that may not yet be on the frontlines of climate risks, and into the broader insurance market beyond property insurance. Congress must step up to examine the problem and propose solutions, working alongside state regulators.  

That’s why it’s heartening to see that Senator Sheldon Whitehouse (D-RI) and the Senate budget committee are holding a hearing on December 18 on the climate-driven insurance crisis. Among the witnesses is Dr. Benjamin Keys, who has done important work in highlighting the role of climate risks in driving increases in insurance premiums.  

According to his research, homeowners in the US saw their annual insurance premiums increase by an average of 33% or $500 between 2020 and 2023. Further, his work analyzing premium increases at the county level shows a stark correlation with places that are more exposed to climate risks.

Earlier this week, Democrats on the Joint Economic Committee, chaired by Senator Martin Heinrich (D-NM), released a report highlighting the growing risks of climate change to insurance and housing markets.  

The non-partisan Congressional Budget Office has also released a recent report and conducted recent briefings on climate change, disaster risk and homeowner’s insurance. One of the challenges they point out is that, even as disasters are worsening, many people are underinsured.  

Low- and moderate-income households are more likely to be underinsured. According to their report: “In 2023, insurers covered $80 billion of the $114 billion of losses attributable to natural disasters, meaning that 30 percent of those losses were not insured.” With insurance premiums increasingly unaffordable, that gap in insurance will likely increase as many people may be forced to go without.  

There are important ways insurance affordability could be tackled by policymakers, including increasing access to parametric insurance, microinsurance programs, and community-based insurance, as well as passing legislation to include means-tested subsidies in the National Flood Insurance Program. Parametric insurance contracts can help simplify and speed up payouts since they are set up based on specific disaster thresholds being crossed (e.g. an earthquake of a certain magnitude or a hurricane with a specific wind speed), rather than being based on an actual evaluation of loss which can take time. Microinsurance programs can provide low-income households access to basic insurance with lower premiums and less comprehensive coverage. Community based insurance is purchased at the community level instead of individual households.  

Insurance companies should also be required to provide more information about why they are increasing rates, how they determine the magnitude of the increases, and what incentives they provide to help homeowners reduce their premiums by investing in risk reduction measures. Regulators must ensure that insurers are not discriminating against low-income policyholders or dropping less profitable lines under the guise of climate impacts.  

Time to act

The crisis in the insurance market we’re seeing today was entirely foreseeable, and largely preventable if we had acted earlier to limit the heat-trapping emissions driving climate change, invest in climate resilience, and enact equity-focused reforms in insurance markets. Climate scientists have been sounding the alarm for decades, and yet the market and policymakers have reacted with short-term strategies because those are the timeframes for determining shareholder value, profits and elections.  

As we look to find ways out of this crisis, let’s keep in mind the continued mismatch in time horizons for decision making in the insurance marketplace and the climate impacts we have unleashed and are locking in for the long term by continuing to burn fossil fuels today. And, in an outrageous contradiction, the insurance industry continues to insure the build-out of fossil fuel infrastructure! 

Data from Swiss Re shows that, globally, insured losses will exceed $135 billion in 2024. Two thirds of that happened in the US, with Hurricanes Helene and Milton alone causing $50 billion in insured losses.

US insurance companies will very likely hike rates again in the new year as global reinsurers reset their rates to reflect the growing costs of disasters worldwide. Rate hikes will hit homeowners hard. Renters, too, as landlords are increasingly passing through this increase in insurance costs in the form of higher rents, thus worsening the housing affordability crunch. More people will find their monthly budgets stretched or be forced to go without insurance and live in fear that they won’t be able to recover from the next disaster.  

The question for policymakers and regulators is whether they are willing to take bold action to help keep insurance available and affordable wherever possible (which unfortunately won’t be everywhere); help people invest in resilience measures to keep their homes and property safer in a warming world; help provide options for people to move away from the highest risk places; and help cut the heat-trapping emissions driving many types of extreme disasters.  

Insurance is one important tool. Let’s make sure it’s working well, guided by the latest science and with strong oversight and equity provisions. And let’s invest in a whole range of necessary actions to complement that because the current insurance crisis is likely just the tip of the iceberg.  

Climate risks are not just affecting the insurance market but also the housing and mortgage markets. And it isn’t just insurance that is increasingly hard to buy, finding safe, affordable housing in places protected from climate extremes is a growing challenge for many low- and middle-income people. 

One thing we can’t afford our policymakers and decisionmakers to do is to deny that climate change is an economic and pocketbook issue.  

As the days grow shorter and I prepare for the holiday season, it’s a fitting moment to reflect on the state of climate litigation—a field that continues to evolve as both a tool for accountability and an arena for climate action. In the past year, we’ve seen significant victories that inspire hope, like the Swiss KlimaSeniorinnen case, which called for an improved government climate action plan; Held v. Montana, where young plaintiffs won the first U.S. trial court ruling affirming a constitutional right to a safe climate; and in Hawaii, which settled a landmark transportation-related case that will fund critical efforts to decarbonize its transit system. These victories illustrate the power of courts to advance meaningful progress in climate governance and highlight the growing importance of science and scientists in providing the evidence needed to inform these legal decisions. 

Yet, progress often feels frustratingly slow. In the U.S., cases challenging fossil fuel companies for decades of climate disinformation remain stalled, tied up by the defendants in procedural wrangling that prevents them from being heard on their merits, delaying justice for affected communities. It’s a familiar frustration: will 2025 finally be the year these cases move forward?  

While I’ve learned not to make bold predictions on this front, I remain cautiously optimistic. In fact, last week the U.S. Department of Justice weighed in on this with two key Supreme Court briefs supporting state-level climate lawsuits. In both cases, the DOJ sided with local governments, arguing that their claims against fossil fuel companies for misleading the public about climate harms should proceed under state law. These briefs underscore a clear federal stance on the importance of preserving state-level legal avenues to address deceptive practices.  

Although US Courts in the U.S. have made progress in hearing other types of climate-related cases, the lack of substantive rulings in disinformation lawsuits is a glaring gap. 

Similarly, even cases that appear to be securing meaningful outcomes often face uncertainties. In the Milieudefensie et al. v. Shell case, for instance, the Dutch courts upheld the ruling that Shell must act to reduce emissions in line with the Paris Agreement. However, the appeal process revealed uncertainties about the precise scale and timing of these reductions, exposing challenges of translating scientific evidence into clear legal mandates. 

This tension—between exciting breakthroughs and persistent delays—underscores the complexity of litigation’s role in climate governance. Courts are emerging as critical players in climate action, especially as a lack of political will and obstruction by fossil fuel interests continue to impede bold outcomes and accountability in international processes like the COP negotiations. I previously wrote about expectations for the incoming Trump presidency, positioning courts as an essential backstop for accountability in the U.S. in the absence of federal leadership. 

The ability of courts to enforce obligations, act on science, and elevate human testimony has never been more crucial. With this in mind, here are three key developments that I believe will shape climate litigation in 2025. 

International Courts Grapple with Climate Change Action  

2025 will undoubtedly be defined by the International Court of Justice (ICJ) and its advisory opinion on states’ obligations to combat climate change. The ICJ hearings, which wrapped last Friday, drew unprecedented global engagement, with a historic number of countries and organizations submitting arguments. These comments repeated an often-shared plea for justice, sustainability, and progress, emphasizing the need for international cooperation rooted in sound science and human rights. 

The ICJ’s advisory opinion has the potential to set a new benchmark for climate accountability. While not legally binding, such opinions hold significant moral and legal influence. They can guide future litigation, encourage governments to align their policies with scientific imperatives, and clarify the responsibilities of states under international law to protect vulnerable populations from climate harms. 

This moment at the ICJ builds on a growing trend of international courts stepping into the climate governance arena. In 2024, the International Tribunal for the Law of the Sea (ITLOS) issued a landmark advisory opinion affirming that greenhouse gas emissions constitute marine pollution under the United Nations Convention on the Law of the Sea (UNCLOS). ITLOS went further, clarifying the obligations of states to prevent, reduce, and control emissions, protect marine ecosystems, and collaborate internationally to address climate-related ocean impacts. While the ruling didn’t impose specific measures, it established UNCLOS as a legal framework for climate accountability that complements other treaties like the Paris Agreement and provides a pathway for legal action. 

Similarly, the Inter-American Court of Human Rights (IACHR) held hearings on climate change and human rights earlier this year, with a focus on the Americas. Submissions from states, NGOs, and individuals emphasized the disproportionate impact of climate change on vulnerable populations,  the need for regional cooperation, and corporate accountability. The IACHR’s forthcoming ruling could further solidify the link between climate action and human rights, providing another layer of legal precedent for addressing the climate crisis. 

Together, these international judicial interventions highlight a growing recognition of the courts as key arbiters in the fight against climate change. When diplomatic negotiations falter, judicial action serves as a complementary pathway, providing a critical counterbalance, grounded in evidence and accountability.  

A Surge in Greenwashing Litigation 

Another defining feature of 2025 will be the continued rise of greenwashing lawsuits. These cases, which challenge companies for making deceptive claims about their climate commitments or sustainability efforts, are becoming a cornerstone of climate litigation. Over 140 such cases have been filed globally since 2016, with 47 new filings in 2023 alone.  

Climate-washing lawsuits are particularly potent because they expose and disrupt the narratives corporations use to greenwash and bolster their reputations while continuing to contribute to the climate crisis. Recent cases have targeted sectors ranging from finance to consumer goods, and the scope is expanding. Courts have ruled against companies for overstating their “net zero” pledges, misleading consumers about the environmental impact of products, and greenwashing their financial products. 

As governments introduce stricter regulations on corporate sustainability claims and public awareness of greenwashing grows, this area of litigation is poised for significant expansion. Beyond penalizing false claims, these lawsuits send a clear message: corporations must back their promises with real, measurable action. 

Post-Disaster and Failure-to-Adapt Cases Gain Ground 

The growing prevalence of climate-related disasters—wildfires, hurricanes, floods—continues to drive litigation targeting both public and private entities. In 2024, lawsuits were increasingly filed in response to catastrophic events, including the Maui wildfires, which devastated communities and underscored systemic vulnerabilities.  

Similarly, earlier this month, the town of Carrboro, North Carolina, file a complaint against Duke Energy, alleging that the utility’s failure to transition from fossil fuels to renewable energy has contributed to intensified weather events, such as flooding and storms, causing significant harm to local infrastructure and residents.  These cases focus on holding governments and corporations accountable for failing to adapt to foreseeable climate risks or mitigate their impacts. 

As courts wrestle with these issues, they are shaping a new era of accountability. Post-disaster cases bring the abstract reality of climate change into sharp relief, translating emissions data into the lived experiences of communities harmed. In 2025, we can expect to see more cases that address the human cost of climate inaction while pushing for systemic change. 

The Critical Role of Courts 

Courts have the ability to enforce accountability in ways that are direct, timely, and rooted in evidence. However, the power of courts to affect change depends on the conditions we create for them to act. This includes fostering robust scientific research, empowering communities to bring cases, and ensuring that legal systems are equipped to handle the complexities of climate litigation. Efforts to integrate science more effectively into legal arguments, help judges accurately interpret technical evidence, and improve access to justice for climate-vulnerable populations are all critical to building a resilient legal framework. Reach out to get involved in our expert working groups and engage in this work with us. 

The ICJ’s deliberations, the rise of climate-washing cases, and the focus on disaster liability all point to the transformative potential of litigation to address the climate crisis. But these legal battles are just one piece of the puzzle. They must be complemented by bold policy action, international cooperation, and a collective commitment to protecting future generations. 

2025 holds immense promise, but it also demands care, creativity, and persistence. While we are facing great challenges in the U.S. and around the world, courts have shown they can play a transformative role in shaping our collective response to climate change. As we look to the year ahead, let us renew our resolve to leverage every available tool—legal, scientific, and political—to combat the greatest challenge of our time. Together, we can create the conditions for a more just, sustainable future. 

Editor’s note: Updates status of investigation into RealPage

Scott Turner’s nomination by President Trump to lead the US Department of Housing and Urban Development (HUD) has garnered less attention than some of his other cabinet picks. This is surprising given the power he wields over millions of people’s most immediate everyday need—having a place to live.   

As the housing and climate crises continue to collide—destroying homes, displacing communities, and causing instability in the insurance industry—it’s important to understand the background of the person selected to lead the agency responsible for policy and programs to address America’s urgent housing needs.

Turner’s track record of advancing ultra-conservative agendas raises valid concern that he would prioritize developer interests while shifting climate risk onto local governments and individuals.   

What does the HUD Secretary do?

As the head of HUD, Scott Turner would oversee a broad, important portfolio of programs that literally helps keep the roof over many people’s heads.

HUD serves a crucial role in providing access to affordable housing for millions of people, including through rental assistance programs, public housing, and pathways to homeownership. These programs are especially important for low-income households, people who live with disabilities, the elderly and families with young children.  

HUD also provides financial support for community and economic development through its Community Development Block Grant Program. The Disaster Recovery (CDBG-DR) component of this program is increasingly important in an era of worsening climate-fueled disasters.  

The question is: if Turner is confirmed as HUD secretary, will he keep the people’s interests as his top priority—or will he be more beholden to deep-pocketed real estate and developer interests?  

Potential conflicts of interest 

To get an idea of how he would lead HUD, it’s important to look at who Scott Turner is. He has had a varied career, including stints in the Texas legislature, the first Trump Administration, and the NFL. During his time in the Texas legislature, Turner stuck mostly to the fiscally and socially conservative Tea Party agenda and didn’t file any housing bills.  

Most recently, Turner has served as a Chief Inspiration Officer for JPI—a development firm that specializes in building multi-family homes across the income spectrum. While it’s essential for the nation’s housing secretary to understand the development landscape, their actions must be rooted in the public interest, not real estate industry interests. The Project 2025 chapter on HUD, authored by former HUD Secretary Ben Carson who Turner considers a mentor, encourages the sale of existing public housing to private, profit-motivated developers.

Additionally, Turner’s former employer has a longstanding and well-publicized relationship with RealPage, a private equity-backed software firm that the US Justice Department claimed enables price-fixing, artificially increasing the rents of hundreds of thousands of renters nationwide. While a criminal investigation into RealPage was recently dropped, a civil lawsuit by the DOJ and eight states remains active. As the average American pays more money than ever before to keep a roof over their head, this confluence of interests and influence should raise concerns during confirmation hearings.   

Opportunity Zones  

In his previous role as a senior official at HUD, Turner was celebrated by President Trump and others for his role in promoting Opportunity Zones. Opportunity Zones were a signature economic development effort of the first Trump administration codified in the 2017 tax bill that allowed investors to defer taxes on capital gains by siphoning those gains into a fund that invested in economically distressed areas. 

The architects of Opportunity Zones claimed the program would spur desirable investment in communities and jumpstart economic revitalization, however, the program didn’t lay out tight regulatory guidelines, and the full impact of the policy isn’t yet obvious as investments can be made through 2026 and some forms of investment (like developing or rehabbing housing) can take years to realize.   

What we do know is that real estate is the largest investment category among Opportunity Zone investors. It’s reported that thousands of affordable homes have been financed in hot housing markets like Charlotte and Austin, but how many of those homes are meaningfully affordable or only nominally affordable, stretching buyers and renters thin, is unclear. 

The return of Opportunity Zones was a key component of the president-elect’s campaign platform, and they are poised for extension in the new administration and Republican-controlled Congress.  If Turner’s job is to champion safe, healthy affordable housing, members of Congress should ask how he intends to strongly condition Opportunity Zones to help address the nation’s housing shortage and whether those benefits will flow to those with lower incomes.  

Reversing climate progress at HUD 

In addition to investing in public housing, rental support and providing pathways to homeownership for low-income families, HUD is also tasked with distributing funds for long-term recovery to cities and states after increasingly frequent and costly disasters.  Cuts to disaster response programs in other federal agencies like FEMA proposed in Project 2025 will almost certainly reduce community resilience and may drive up the price tag of long-term recovery that Turner is tasked with administering. 

In the last few years, HUD has adopted climate initiatives to make affiliated properties more energy efficient, weatherize buildings against extreme heat and reduce flood risk. Project 2025 recommends eliminating the agency’s climate programs. The climate denialism of these proposed repeals aside, the conservative playbook’s obsession with reducing government spending simply transfers risk to levels of government and communities less equipped than the federal government to pursue resilience.  

HUD’s climate initiatives are intended to keep communities safer and tackle climate challenges that, if left unchecked, will have increasingly expensive impacts on its assets and risk the lives of people the agency has a responsibility to protect.

Members of Congress should probe Turner on the true, long-term cost of walking away from common sense climate efforts like weatherization and floodplain standards.   

Project 2025 regurgitates rejected policies

It’s too soon to tell just how much of President Trump’s dangerous agenda Scott might be able to realize as HUD Secretary.  Much of the Project 2025 plan for the agency are policies that were rejected or unfinished during the first Trump presidency, which like the coming administration also began with a Republican-controlled congress.

Other parts of President Trump’s agenda like his inhumane threats of mass deportation could make it harder to build affordable homes. With an electorate deeply concerned about making ends meet, it’s important that confirmation hearings reveal who Turner will center in his leadership—a nation struggling with housing costs and growing climate risk or his real estate industry colleagues.
