“What’s Left,” by Malcolm Harris, arrives at a particularly difficult time to consider anything beyond our immediate turmoil.

“Ocean,” now on view on the coast of Denmark, fuses past with present, and art with science to raise urgent questions about our relationship with the sea.

Crowds of tourists bound for Antarctica have brought prosperity to Argentina’s southernmost city, but the boom is also squeezing locals and stressing the environment.

European State of the Climate report ‘lays bare’ impact of fossil fuels on continent during its hottest 12 months on record

The home-wrecking storms and floods that swept Europe last year affected 413,000 people, a report has found, as fossil fuel pollution forced the continent to suffer through its hottest year on record.

Dramatic scenes of cars piled up on inundated streets and bridges being ripped away by raging torrents were seen around the continent in 2024, with “high” floods on 30% of the European river network and 12% crossing the “severe” flood threshold, according to the European State of the Climate report.

Hotter seas supercharge storms and destroy critical ecosystems such as kelp forests and coral reefs

The climate crisis has tripled the length of ocean heatwaves, a study has found, supercharging deadly storms and destroying critical ecosystems such as kelp forests and coral reefs.

Half of the marine heatwaves since 2000 would not have happened without global heating, which is caused by burning fossil fuels. The heatwaves have not only become more frequent but also more intense: 1C warmer on average, but much hotter in some places, the scientists said.

In letters to multiple agencies, the focus is on how job reductions at E.P.A., Interior and other agencies would hurt President Trump’s “energy dominance” agenda.

Coal has been displaced by cheap and plentiful natural gas and the rapid growth of wind and solar energy — forces that President Trump will struggle to do away with.

The Trump administration’s governance — and the president’s unhinged trade war on the entire world — has hurt America’s ability to meet climate goals.

The governing ideology of the far right has become a monstrous, supremacist survivalism. Our task is to build a movement strong enough to stop them

The movement for corporate city states cannot believe its good luck. For years, it has been pushing the extreme notion that wealthy, tax-averse people should up and start their own high-tech fiefdoms, whether new countries on artificial islands in international waters (“seasteading”) or pro-business “freedom cities” such as Próspera, a glorified gated community combined with a wild west med spa on a Honduran island.

Yet despite backing from the heavy-hitter venture capitalists Peter Thiel and Marc Andreessen, their extreme libertarian dreams kept bogging down: it turns out most self-respecting rich people don’t actually want to live on floating oil rigs, even if it means lower taxes, and while Próspera might be nice for a holiday and some body “upgrades”, its extra-national status is currently being challenged in court.

Almost as amazing as the knowledge we have gained in the past four decades is the fact that some people continue to deny the damage we are doing to our world

Earlier this year I received an email from a reader asking background questions about an article I had written more than four decades ago. Given the time gap, my recollection was hazy. To be honest, it was almost non-existent. So I was intrigued – and then astonished when I read the feature.

I had written about the British glaciologist John Mercer, author of a 1978 Nature paper in which he warned that continuing increases in fossil fuel consumption would cause amounts of atmospheric carbon dioxide to soar. Global temperatures could rise by 2C by the mid-21st century, causing major ice loss at the poles and threatening a 5-metre rise in sea levels, he warned.

For beekeepers, the problem isn’t just climate change and extreme weather: It’s also DOGE, the trade war and the immigration crackdown.

President Trump may be turning relations with NATO and Russia inside out, but winter war games revealed that two militaries’ cooperation was unchanged.

Even the hardy eucalypts are finding their limits as we experience more frequent bushfires, heatwaves and droughts

Last week I went to Adelaide to see a man about a tree. The man was Dr Dean Nicolle and the tree was actually 10,000 eucalypt trees and mallees, of over 800 species, which Dean has been planting on a block of land south of Adelaide since 1993.

Dean’s passion for eucalypts is incredible. It makes me realise that so much conservation happens purely because someone is just absolutely captivated by something. And thank goodness Dean is, because his love for the eucalypt made the Currency Creek Arboretum, which is designed to bring together all of Australia’s eucalypt species in one place for research.

A Trump administration budget proposal would essentially eliminate one of the world’s foremost Earth sciences research operations.

Ann Arbor, Mich., moved forward with an ambitious plan to build its own utility that aims provide clean power outside the grid.

The president is trying new shortcuts to eliminate energy and environmental rules, but legal experts say the efforts could face high hurdles.

A draft global agreement sets a fee for cargo ships, which carry the vast majority of world trade, to pay for their greenhouse gas emissions.

Nearly 2m hectares of forests suitable for endangered koalas have been destroyed since the iconic species was declared a threatened species in 2011, according to analysis for Guardian Australia.

The scale of habitat destruction in Queensland and New South Wales – states in which the koala is formally recognised as being at risk of extinction – has continued despite political promises it would be protected.

Clean energy investors likely to pull back from US, but other countries may seize opportunity to speed transition

Donald Trump’s upending of the global economy has raised fears that climate action could emerge as a casualty of the trade war.

In the week that has followed “liberation day”, economic experts have warned that the swathe of tariffs could trigger a global economic recession, with far-reaching consequences for investors – including those behind the green energy projects needed to meet climate goals.
