Climate

Meteorologists and climate researchers aim to run a livestream for 100 hours in protest of the Trump administration’s cuts to weather and climate research.

The judge asked lawyers how a suit by Charleston, S.C., claiming oil companies misled people about climate risks, might be affected by a Trump executive order blasting cases like these.

The 24 awards would have gone to a range of companies trying in novel ways to reduce the pollution that is heating the planet.

Nigerian authorities said they had expected flooding as part of the rainy season but were surprised by the extent of the damage.

High-profile Nationals and powerful forces in business and media are pushing back against climate action, posing a test of credibility for the new Liberal leader

After another scrappy week for the faltering Coalition, Bridget McKenzie on Thursday called for the National party to stop talking about itself.

No sane observer of politics since the 3 May election could disagree, but the party’s Senate leader made the observation in an awkward setting: a Sky News interview.

Even in the foothills of the Italian Alps, cycling can be a practical alternative to driving, and more enjoyable, too

Living car-free in a big city is fairly common these days. Yes, it can mean some adaptation, but when so many things are on your doorstep it’s not such a big challenge. So how about car-free life in a remote Italian mountain village, with barely any public transport?

We have been living in rural Italy without a car for more than five years now. Even though we have always loved bicycles, the decision to sell our car wasn’t a particularly considered one.

Academic Neta Crawford warns that if Donald Trump follows through on his threats of war, emissions will soar and the planet will pay the price

• Carbon footprint of Israel’s war on Gaza exceeds that of many entire countries

• Revealed: Nato rearmament could increase emissions by 200m tonnes a year

The climate impact of Donald Trump’s geopolitical ambitions could deepen planetary catastrophe, triggering a global military buildup that accelerates greenhouse gas emissions, a leading expert has warned.

The Pentagon – the US armed forces and Department of Defense (DoD) agencies – is the world’s largest institutional greenhouse gas emitter, accounting for at least 1% of total US emissions annually, according to analysis by Neta Crawford, co-founder of the Costs of War project at Brown University.

Exclusive: Climate cost of war is more than than the combined 2023 emissions of Costa Rica and Estonia, study finds

• How the US became the biggest military emitter and stopped everyone finding out

• Revealed: Nato rearmament could increase emissions by 200m tonnes a year

The carbon footprint of the first 15 months of Israel’s war on Gaza will be greater than the annual planet-warming emissions of a hundred individual countries, exacerbating the global climate emergency on top of the huge civilian death toll, new research reveals.

A study shared exclusively with the Guardian found the long-term climate cost of destroying, clearing and rebuilding Gaza could top 31m tonnes of carbon dioxide equivalent (tCO2e). This is more than the combined 2023 annual greenhouse gases emitted by Costa Rica and Estonia, yet there is no obligation for states to report military emissions to the UN climate body.

Over 99% of the almost 1.89m tCO2e estimated to have been generated between the 7 October 2023 Hamas attack and the temporary ceasefire in January 2025 is attributed to Israel’s aerial bombardment and ground invasion of Gaza.

Almost 30% of greenhouse gases generated in that period came from the US sending 50,000 tonnes of weapons and other military supplies to Israel, mostly on cargo planes and ships from stockpiles in Europe. Another 20% is attributed to Israeli aircraft reconnaissance and bombing missions, tanks and fuel from other military vehicles, as well as CO2 generated by manufacturing and exploding the bombs and artillery.

Solar had generated as much as a quarter of Gaza’s electricity, representing one of the world’s highest shares, but most panels, and the territory’s only power plant, have been damaged or destroyed. Gaza’s limited access to electricity now mostly relies on diesel-guzzling generators that emitted just over 130,000 tons of greenhouse gases into the atmosphere, or 7% of the total conflict emissions.

More than 40% of the total emissions were generated by the estimated 70,000 aid trucks Israel allowed into the Gaza Strip – which the UN has condemned as grossly insufficient to meet the basic humanitarian needs of 2.2m displaced and starving Palestinians.

An energy company plans to revive pipelines that were blocked on environmental grounds, as President Trump pushes states on fossil fuel projects.

Oil and gas companies are facing a wave of new lawsuits over their role in global warming.

The National Weather Service warned of “dangerously hot conditions” from Friday through Sunday.

Twenty-two plaintiffs between ages seven and 25 allege government is engaging in unlawful executive overreach

Twenty-two young Americans have filed a new lawsuit against the Trump administration over its anti-environment executive orders. By intentionally boosting oil and gas production and stymying carbon-free energy, federal officials are violating their constitutional rights to life and liberty, alleges the lawsuit, filed on Thursday.

The federal government is engaging in unlawful executive overreach by breaching congressional mandates to protect ecosystems and public health, argue the plaintiffs, who are between the ages of seven and 25 and hail from the heavily climate-impacted states of Montana, Hawaii, Oregon, California and Florida. They also say officials’ emissions-increasing and science-suppressing orders have violated the state-created danger doctrine, a legal principle meant to prevent government actors from inflicting injury upon their citizens.

What would make you want to have more children?

Experts said it is the first wrongful death case targeting fossil fuel companies over their role in global warming.

The complaint argues that orders aimed at increasing American fossil fuel production infringe on the fundamental rights of young people.

Wildlife sanctuary manager Josh McAllister was stranded for three days with six tins of tuna, a bag of Doritos and a salad roll – but he was more worried about the bettongs

When heavy monsoonal rain was forecast in north Queensland at the beginning of February, Josh McAllister and his family headed to Townsville to stock up on supplies.

As the rain came down, his partner and children did the bolt to home on Australian Wildlife Conservancy’s (AWC) Mount Zero-Taravale wildlife sanctuary, 80km to the north-west, taking with them the groceries. McAllister stayed in town to complete a few jobs.

Former army and navy leaders urge government to think beyond military capability in advance of key defence review

Former military leaders are urging the UK government to widen its definition of national security to include climate, food and energy measures in advance of a planned multibillion-pound boost in defence spending.

Earlier this year Keir Starmer announced the biggest increase in defence spending in the UK since the end of the cold war, with the budget rising to 2.5% of GDP by 2027 – three years earlier than planned – and an ambition to reach 3%.

The new executive order allows political appointees to undermine research they oppose, paving the way for state-controlled science

Science is under siege.

On Friday evening, the White House released an executive order called Restoring Gold Standard Science. At face value, this order promises a commitment to federally funded research that is “transparent, rigorous, and impactful” and policy that is informed by “the most credible, reliable, and impartial scientific evidence available”. But hidden beneath the scientific rhetoric is a plan that would destroy scientific independence in the US by giving political appointees the latitude to dismiss entire bodies of research and punish researchers who fail to fall in line with the current administration’s objectives. In other words: this is Fool’s-Gold Standard Science.
