Democratic presidential nominee has raised alarm about Trump’s plans but has not said much about her own

• US politics – live updates

As the US south-east struggles to rebuild after two deadly and climate-fueled hurricanes, some environmental advocates are demanding Kamala Harris flesh out a strong climate plan.

Since Hurricanes Helene and Milton ravaged parts of the country, the vice-president has slammed Donald Trump’s climate record by airing a new campaign ad showing the oft-criticized moment the former president redrew a hurricane’s path with a marker, and taking aim at Trump’s spread of climate misinformation and history of withholding disaster aid.

It’s all in the line of sight

Survey of young people aged 16-25 from all US states shows concerns across political spectrum

The overwhelming majority of young Americans worry about the climate crisis, and more than half say their concerns about the environment will affect where they decide to live and whether to have children, new research finds.

The study comes just weeks after back-to-back hurricanes, Helene and Milton, pummeled the south-eastern US. Flooding from Helene caused more than 600 miles of destruction, from Florida’s west coast to the mountains of North Carolina, while Milton raked across the Florida peninsula less than two weeks later.

Oil majors’ conduct can constitute reckless endangerment due to fossil fuels’ affect on global heating, advocates claim

New York state prosecutors could press criminal charges against big oil for its role in fueling hurricanes and other climate disasters, lawyers wrote in a new prosecution memorandum that has been endorsed by elected officials across the state.

The 50-page document, published by the consumer advocacy group Public Citizen and the progressive prosecutors network Fair and Just Prosecution on Thursday, comes as the US south-east struggles to recover from the deadly hurricanes Helene and Milton, both of which scientists have found were exacerbated by the climate crisis. It details the havoc wrought on New York by 2021’s Hurricane Ida and 2012’s Hurricane Sandy, and other deadly climate events such as extreme heatwaves across the US this past summer.

The destruction in northern Italy has ignited debate in a country where just 6% of homes are insured against natural disaster

It was 2am when the parish priest, Giovanni Samorì, was woken by a phone call from the mayor of Traversara ordering him to start ringing the church bells. The traditional call now forms part of the civil protection procedure deployed by many Italian towns. Its aim: to warn residents of impending calamity.

As torrential rain pounded the village, Samorì sprang into action, a task he compares to “sounding the death knell”. It worked: the evacuation of Traversara’s 480 residents was swift and, despite the priest’s foreboding, there were no deaths.

Landmark review says urgent action needed to conserve resources and save ecosystems that supply fresh water

More than half the world’s food production will be at risk of failure within the next 25 years as a rapidly accelerating water crisis grips the planet, unless urgent action is taken to conserve water resources and end the destruction of the ecosystems on which our fresh water depends, experts have warned in a landmark review.

Half the world’s population already faces water scarcity, and that number is set to rise as the climate crisis worsens, according to a report from the Global Commission on the Economics of Water published on Thursday.

Emergency requests by 27 states to pause rule requiring fossil fuel-powered plants to reduce emissions were denied

The US supreme court declined on Wednesday to put on hold a new federal rule targeting carbon pollution from coal- and gas-fired power plants at the request of numerous states and industry groups in another major challenge to Joe Biden’s efforts to combat climate change.

The justices denied emergency requests by West Virginia, Indiana and 25 other states – most of them Republican-led – as well as power companies and industry associations, to halt the Environmental Protection Agency (EPA) rule while litigation continues in a lower court. The regulation, aimed at cutting greenhouse gas emissions that drive the climate crisis, took effect on 8 July.

Shoshone national forest officials pause gruesome policy of exploding carcasses to minimize hazard during dry spell

Rangers in Wyoming’s Shoshone national forest believe they have figured out how to mitigate an elevated risk of wildfires: they are no longer using explosives to blow up dead horses.

The temporary pause in the seemingly bizarre and somewhat gruesome policy comes as a lengthy dry spell in the state’s backcountry combines with hotter-than-usual temperatures, increasing the possibility of wildfires. Experts say drought and heat from the climate crisis is fueling a rise in extreme wildfires worldwide.

The devastation wrought by Helene and Milton could shake up priorities and bring the climate crisis more to the fore

Despite its enormous implications, the climate crisis has so far mostly been a dormant issue in the US presidential election. Some hope the devastation wrought in quick succession by two major hurricanes will shake up the priorities of American voters before a stark choice between Kamala Harris and Donald Trump on polling day.

Last month, Hurricane Helene became one of the deadliest storms ever to hit the US, killing more than 220 people and causing billions of dollars in damage as it tore a path northwards, through the key election swing states of Georgia and North Carolina. This was followed two weeks later by Hurricane Milton, which rampaged across Florida.

Tech barons are forever predicting some amazing new technology to fix the climate crisis. Yet fixes already exist

There are so many ways to fiddle while Rome burns, or as this season’s weather would have it, gets torn apart by hurricanes and tornadoes and also goes underwater – and, in other places, burns. One particularly pernicious way comes from the men in love with big tech, who are forever insisting that we need some amazing new technology to solve our problems, be it geoengineering, carbon sequestration or fusion – but wait, it gets worse.

At an artificial intelligence conference in Washington DC, the former Google CEO Eric Schmidt recently claimed that “[w]e’re not going to hit the climate goals anyway because we’re not organized to do it” and that we should just plunge ahead with AI, which is so huge an energy hog it’s prompted a number of tech companies to abandon their climate goals. Schmidt then threw out the farfetched notion that we should go all in on AI because maybe AI will somehow, maybe, eventually know how to “solve” climate, saying: “I’d rather bet on AI solving the problem than constraining it.”

Wolsingham school’s carbon-cutting event had been planned by pupils but parents raised concerns

A school has made a U-turn on a student-led plan to turn the heating off for a “blue nose” climate action day after parents raised concerns.

The heating was due to be turned off at Wolsingham school, County Durham, on Friday but the plan has now been postponed until the summer term of next year when it is likely to be warmer.

As the threats of climate change continue to become realities in new and sometimes terrifying ways, more and more teams and leagues will have to address the problem

The Arizona Diamondbacks have a climate problem. To be more precise, Phoenix has a climate problem and, as a result, the Diamondbacks have a field that needs renovations if the team is going to keep fans cool – and no one is sure whose responsibility it is to pay for it.

The team’s lease on Chase Field expires in 2027, and negotiations with Maricopa county have stalled. The organization’s plan to fund the $400m to $500m project is modeled on the Arizona Cardinals’ successful bid to fund their own field renovation through stadium sales and recaptured income, and the plan is supported by the Chamber of Commerce, the Arizona Chamber of Commerce and Industry, Greater Phoenix Leadership, the Economic Council and Downtown Phoenix, Inc.

Bring in ‘future homes standard’ or leave families at risk of higher bills and emissions for decades, MPs and experts say

Ministers must take steps now to ensure that all homes are built to the most efficient low-carbon standards, or risk locking households into higher bills and greenhouse gas emissions for decades to come, a group of MPs and experts have urged.

The government is mulling changes to the building regulations in England to bring in a “future homes standard” that would require all new homes to be built with low-carbon equipment such as heat pumps and solar panels.

In 2020, nine bodies were found near US-Mexico border. In the first eight months of 2024, there were 108.

Ten times as many migrants died in New Mexico near the US-Mexico border in each of the last two years compared with just five years ago.

During the first eight months of 2024, the bodies of 108 presumed migrants, mostly from Mexico and Central America, were found near the border in New Mexico, according to the most recent data. Many of the bodies were discovered less than 10 miles (16km) from El Paso.

Institutional investors dealing with portfolios in the trillions of dollars aren’t typically the most vocal climate campaigners. You won’t find many superannuation fund staff, fund managers, asset consultants or brokers with a placard on the streets or on top of a Newcastle coal train.

But you may increasingly find them on a screen you’re watching. Or at least their message.

UC San Diego has added an innovative prerequisite to ‘prepare students for the future they really will encounter’

Melani Callicott, a human biology major at the University of California, San Diego, thinks about the climate crisis all the time. She discusses it with family and friends because of the intensity of hurricanes like Milton and Helene, which have ravaged the southern US, she says. “It just seems like it’s affecting more people every day.”

That’s one reason why she is glad that UC San Diego has implemented an innovative graduation requirement for students starting this autumn: a course in climate change. Courses must cover at least 30% climate-related content and address two of four areas, including scientific foundations, human impacts, mitigation strategies and project-based learning. About 7,000 students from the class of 2028 will be affected this year.

Natural sinks of forests and peat were key to Finland’s ambitious target to be carbon neutral by 2035. But now, the land has started emitting more greenhouse gases than it stores

Read more: Trees and land absorbed almost no CO2 last year. Is nature’s carbon sink failing?

Tiina Sanila-Aikio cannot remember a summer this warm. The months of midnight sun around Inari, in Finnish Lapland, have been hot and dry. Conifer needles on the branch-tips are orange when they should be a deep green. The moss on the forest floor, usually swollen with water, has withered.

“I have spoken with many old reindeer herders who have never experienced the heat that we’ve had this summer. The sun keeps shining and it never rains,” says Sanila-Aikio, former president of the Finnish Sami parliament.

A US study estimates the total climate pollution from LNG was 33% greater than that from coal over a 20-year period. This should have major ramifications for emissions policy

The claim that Australian gas exports are “clean” and needed to drive the transition to net zero greenhouse gas emissions has become an article of faith for significant parts of the country’s industry, media and political classes – often repeated, only occasionally challenged.

It has buttressed a massive expansion of the liquified natural gas (LNG) industry in the north of the continent over the past decade, with major new developments in Queensland, Western Australia and the Northern Territory.

The sudden collapse of carbon sinks was not factored into climate models – and could rapidly accelerate global heating

It begins each day at nightfall. As the light disappears, billions of zooplankton, crustaceans and other marine organisms rise to the ocean surface to feed on microscopic algae, returning to the depths at sunrise. The waste from this frenzy – Earth’s largest migration of creatures – sinks to the ocean floor, removing millions of tonnes of carbon from the atmosphere each year.

This activity is one of thousands of natural processes that regulate the Earth’s climate. Together, the planet’s oceans, forests, soils and other natural carbon sinks absorb about half of all human emissions.

New climate network will teach trainee doctors more about heatstroke, dengue and malaria and role of global warming in health

Mosquito-borne diseases such as dengue and malaria will become a bigger part of the curriculum at medical schools across Europe in the face of the climate crisis.

Future doctors will also have more training on how to recognise and treat heatstroke, and be expected to take the climate impact of treatments such as inhalers for asthma into account, medical school leaders said, announcing the formation of the European Network on Climate & Health Education (Enche).
