Blazes in some parts of the country are up by 1,200% since last year, as charities warn about effects on wildlife

Entire ecosystems have been “decimated” and endangered species put at risk after one of the worst wildfire seasons on record in the UK, charities have warned.

Vast areas of habitat for animals including butterflies, beetles and falcons have been damaged, and some peat bogs may take “hundreds of years” to recover following one of the driest Marches in decades combined with warmer than average temperatures in April.

Researchers say urgent action needed to inform people about risks of heatwave temperatures and adapt homes

The number of UK homes overheating in summer quadrupled to 80% over the past decade, according to a study, with experts calling the situation a crisis.

Heat already kills thousands of people each year in the UK and the toll will rise as the climate crisis intensifies. Urgent action is needed both to inform people on how to cope with high temperatures and to adapt homes, which are largely designed to keep heat in during the winter, the researchers said.

Cuts to disaster agency and deregulation of fossil fuels, plus rise of water-guzzling datacentres, highlighted in new report

The Trump administration’s sweeping cuts to the federal climate disaster agency – and the full-throttle deregulation of fossil fuels and water-guzzling datacentres – could prove catastrophic for America’s endangered rivers, threatening the food, water and livelihoods of millions of people, according to a new report.

American Rivers’ annual most-endangered rivers list lays bare a myriad of human-made threats including floods, drought and other extreme weather events driven by the climate crisis, as well as industrial pollution and poor river management – all of which Trump’s regulatory rollbacks will almost inevitably make worse.

The Coalition MP Colin Boyce says he believes the way to turn voters against renewable energy is to “let Rome burn for a while” and allow power blackouts to occur in major cities.

Guardian Australia reported on Wednesday that Boyce had described blackouts as a “big political opportunity” at a meeting of climate science deniers in late 2023.

Exclusive: Absence of world’s biggest clean energy producer will be welcomed by US pushing oil and gas exports

China is to snub a major UK summit on energy security next week, the Guardian has learned, amid a growing row over the country’s involvement in UK infrastructure projects.

The US will send a senior White House official to the 60-country summit, to be co-hosted with the International Energy Agency. Leading oil and gas companies are also invited, along with big technology businesses, and petrostates including Saudi Arabia, Qatar and the United Arab Emirates.

Energy watchdog cuts forecast for growth in demand by a third, and says a trade war could mean it falls further

The world will use less crude oil than expected this year due the “substantial risks” posed by Donald Trump’s trade tariffs to the global economy, according to the global energy watchdog.

The International Energy Agency slashed its forecasts for global oil demand growth by a third for the year ahead, and warned that it could make further downward revisions depending on whether a trade war develops.

Parts of the state record their lowest rainfall on record, with devastating impacts on freshwater fish, butterflies, bees and even some hardy trees

Usually hardy trees and shrubs are dying, waterways have turned to dust and ecologists fear local freshwater fish extinctions could be coming as historic dry conditions grip parts of South Australia.

Large swathes of the state – including the Adelaide Plains, the Fleurieu, Yorke and Eyre peninsulas and upper south-east – have seen the lowest rainfall on record in the 14 months since February 2024, according to the Bureau of Meteorology.

The White House has pulled federal webpages tracking climate and environmental justice data

• US politics live – latest updates

Green groups have sued the Trump administration over the removal of government webpages containing federal climate and environmental justice data that they described as “tantamount to theft”.

In the first weeks of its second term, the Trump administration pulled federal websites tracking shifts in the climate, pollution and extreme weather impacts on low-income communities, and identifying pieces of infrastructure that are extremely vulnerable to climate disasters.

With extreme weather and Trump’s looming trade war, US farmers are reeling and resigned to needing another bailout

Farmers across the United States say they could face financial ruin – unless there is a huge taxpayer funded bail out to compensate for losses generated by Donald Trump’s sweeping cuts and chaotic tariffs.

Small- and medium-sized farms were already struggling amid worsening climate shocks and volatile commodities markets, on top of being squeezed by large corporations that dominate the supply chain.

As part of Trump’s administrations ‘efficiency’ drive, staff running decades old program for energy assistance laid off

Robert F Kennedy Jr, the secretary of Health and Human Services (HHS), is facing new demands to release almost $400m allocated by Congress to help low-income US families keep the air conditioning on this summer.

The funds are under threat after the staff running a decades old program were fired – as part of the Trump administration’s so-called ‘efficiency’ drive.

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.

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.

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.

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.

Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online

A leaked document shows that vested interests may have been behind a “mud-slinging” PR campaign to discredit a landmark environment study, according to an investigation.

The Eat-Lancet Commission study, published in 2019, set out to answer the question: how can we feed the world’s growing population without causing catastrophic climate breakdown?

There has been little talk about how Australia’s economy will get to net zero. That’s a terrible reflection on the state of our politics

The Coalition has been forced to reassert its commitment to the Paris climate agreement after its energy spokesperson, Ted O’Brien, appeared to waver on the pledge on Thursday.

O’Brien faced off against the climate change and energy minister, Chris Bowen, at a debate in Canberra, weeks out from a federal election in which energy policy is emerging as a hot-button issue.

Labor, the Coalition, nobody in this country will be able to achieve the emission target set by Chris Bowen and Anthony Albanese. The difference between Peter Dutton and Anthony Albanese is that Peter Dutton has been honest and upfront about that.

… go against the spirit, if not the letter, of the Paris Agreement, and – in some circumstances – could constitute a breach of those obligations.
