Extreme heat ‘the new normal’, says UN chief, as authorities across the continent issue health warnings
Rapporteur calls for defossilization of economies and urgent reparations to avert ‘catastrophic’ rights and climate harms
The Kenyan marine ecologist David Obura is chair of a panel of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the world’s leading natural scientists. For many decades, his speciality has been corals, but he has warned that the next generation may not see their glory because so many reefs are now “flickering out across the world”.

Les scientifiques ont déclaré aujourd’hui que les océans de la planète sont en plus mauvaise santé qu’on ne le pensait, tout en avertissant qu’une mesure clé montre que nous « manquons de temps » pour protéger les écosystèmes marins. L’acidification des océans, souvent appelée le « jumeau maléfique » de la crise climatique, est causée par l’absorption rapide du dioxyde de carbone par les océans, où il réagit avec les molécules d’eau, entraînant une baisse du pH de l’eau de mer. Elle endommage les récifs coralliens et d’autres habitats océaniques et, dans les cas extrêmes, peut dissoudre les coquilles des créatures marines.
Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today. But what if there was another, greater, human-made threat that could snuff out not only human civilisation, but practically the entire biosphere, in the blink of an eye?
Guardian investigation finds almost 7,000 proven cases of cheating – and experts says these are tip of the iceberg
Ocean acidification has already crossed a crucial threshold for planetary health, scientists say in unexpected finding
There’s frustration among researchers that falling pH levels in seas around the globe are not being taken seriously enough, and that until the buildup of CO2 is addressed, the consequences for marine life will be devastating
A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides
La pandémie et les lois sévères ont étouffé les mouvements climatiques tels que nous les connaissions. Préparez-vous à un nouveau type d’action. […] Le mouvement a remporté des victoires impressionnantes. Sa première exigence, « dire la vérité », a été essentiellement honorée lorsque le Royaume-Uni est devenu le premier pays au monde à déclarer officiellement une urgence climatique, quelques jours après la fin de la rébellion d’avril. Le mouvement a également suscité un sentiment d’urgence parmi le public.
On 21 April 2019, I was on Waterloo Bridge in London with my younger siblings. Around us were planters full of flowers where there were once cars, and people singing. This was the spring iteration of Extinction Rebellion, when four bridges in London were held by protesters. My siblings, then 14, had been going out on school strike inspired by Greta Thunberg, and wanted to see her speak.
Toxic pollution from wildfires has infiltrated the homes of more than a billion people a year over the last two decades, according to new research. The climate crisis is driving up the risk of wildfires by increasing heatwaves and droughts, making the issue of wildfire smoke a “pressing global issue”, scientists said.
Paper in Nature Climate Change journal reveals major role wealthy emitters play in driving climate extremes. The world’s wealthiest 10% are responsible for two-thirds of global heating since 1990, driving droughts and heatwaves in the poorest parts of the world, according to a study.
The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study. It found a rising trend in micro- and nanoplastics in brain tissue from dozens of postmortems carried out between 1997 and 2024. The researchers also found the tiny particles in liver and kidney samples.
The faces are different, but it’s the same authoritarianism. Keir Starmer’s team might not look or sound like Donald Trump’s, but its policies on protest and dissent are chillingly similar. So is the reason: coordinated global lobbying by the rich and powerful, fronted by rightwing junktanks.

Une majorité silencieuse de la population mondiale souhaite une action climatique plus forte. Il est temps de se réveiller. Environ 89 % des citoyens souhaitent que leurs gouvernements fassent davantage pour lutter contre la crise climatique, mais ils ne savent pas qu’ils constituent la majorité. Le Guardian s’associe à des dizaines de rédactions du monde entier pour lancer le projet 89 % et mettre en évidence le fait que la grande majorité de la population mondiale souhaite une action en faveur du climat.
A superpower in the fight against global heating is hiding in plain sight. It turns out that the overwhelming majority of people in the world – between 80% and 89%, according to a growing number of peer-reviewed scientific studies – want their governments to take stronger climate action.

Microplastics have been found for the first time in human ovary follicular fluid, raising a new round of questions about the ubiquitous and toxic substances’ potential impact on women’s fertility. The new peer-reviewed research published in Ecotoxicology and Environmental Safety checked for microplastics in the follicular fluid of 18 women undergoing assisted reproductive treatment at a fertility clinic in Salerno, Italy, and detected them in 14.
Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.
Greenpeace lost – not because it did something wrong but because it was denied a fair trial The stunning $667m verdict against Greenpeace last week is a direct attack on the climate movement, Indigenous peoples and the first amendment. The North Dakota case is so deeply flawed – at its core, the trial was really about crushing dissent – that I believe there is a good chance it will be reversed on appeal and ultimately backfire against the Energy Transfer pipeline company.
The world’s oceans have been set to simmer, and the heat is being cranked up. Last year saw the hottest ocean temperatures in recorded history, the sixth consecutive year that this record has been broken, according to new research.

The multibillion-dollar chemicals company 3M told customers its firefighting foams were harmless and biodegradable when it knew they contained toxic substances so persistent they are now known as “forever chemicals” and banned in many countries including the UK, newly uncovered documents show.
Donald Trump has ordered that swathes of America’s forests be felled for timber, evading rules to protect endangered species while doing so and raising the prospect of chainsaws razing some of the most ecologically important trees in the US. The president, in an executive order, has demanded an expansion in tree cutting across 280m acres (113m hectares) of national forests and other public lands, claiming that “heavy-handed federal policies” have made America reliant on foreign imports of timber.
His Royal Highness King Godwin Bebe Okpabi has carried bottles of water drawn from the wells of his homeland in the Niger delta to the high court in London. For the past three and a half weeks, lawyers for Shell have argued at the high court that their client cannot be held responsible for an environmental catastrophe in Ogale, which has suffered from decades of spills and pollution from oil extraction.

As fossil fuel interests attack climate accountability litigation, environmental advocates have sounded a new warning that they are pursuing a path that would destroy all future prospects for such cases. Nearly 200 advocacy groups have urged Democratic representatives to “proactively and affirmatively” reject potential industry attempts to obtain immunity from litigation.
Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.
The researchers estimated an extra 8,000 people would die each year as a result of “suboptimal temperatures” even under the most optimistic scenario for cutting planet-heating pollution. The hottest plausible scenario they considered showed a net increase of 80,000 temperature-related deaths a year.
n the UK, when climate activists want to block a road, they sit down on it. When their fellow activists in France want to do the same, they build a wall across one side, and set the other side on fire. As Extinction Rebellion drew tens of thousands to their peaceful “Big One” protests in London last month, in the south of France 8,500 environmental protesters occupied the road from Toulouse to the town of Castres.
JD Vance was supposed to be the inconsequential vice-president. But his starring role in Friday’s blowup between Donald Trump and Volodymyr Zelenskyy – where he played a cross between Trump’s bulldog and a tech bro Iago – may mark the moment that the postwar alliance between Europe and the US finally collapsed.

Analysis shows fossil fuels are supercharging heatwaves, leaving millions prone to deadly temperatures
Thirteen of the ports with the highest supertanker traffic will be seriously damaged by just 1 metre of sea level rise, the analysis found. The researchers said two low-lying ports in Saudi Arabia – Ras Tanura and Yanbu – were particularly vulnerable. Both are operated by Aramco, the Saudi state oil firm, and 98% of the country’s oil exports leave via these ports.
The economic damage wrought by climate change is six times worse than previously thought, with global heating set to shrink wealth at a rate consistent with the level of financial losses of a continuing permanent war, research has found. A 1C increase in global temperature leads to a 12% decline in world gross domestic product (GDP), the researchers found, a far higher estimate than that of previous analyses.

A panel of international scientists has moved their symbolic “Doomsday Clock” closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine, tensions in other world hotspots, military applications of artificial intelligence and the climate crisis as factors underlying the risks of global catastrophe.
In 1919, at the height of a global crisis that resulted from the turmoil of the Russian Revolution, the devastation of the first world war, and the collapse of Europe’s great continental empires, Irish writer William Butler Yeats penned his famed warning to humanity, mourning the end of the old world: “Things fall apart; the centre cannot hold / Mere anarchy is loosed upon the world.”
The world’s addiction to fossil fuels is a “Frankenstein’s monster sparing nothing and no one”, the UN secretary general, António Guterres, told leaders at the World Economic Forum in Davos on Wednesday. “Our fossil fuel addiction is a Frankenstein’s monster, sparing nothing and no one. All around us, we see clear signs that the monster has become master,”
he global economy could face 50% loss in gross domestic product (GDP) between 2070 and 2090 from the catastrophic shocks of climate change unless immediate action by political leaders is taken to decarbonise and restore nature, according to a new report The stark warning from risk management experts the Institute and Faculty of Actuaries (IFoA) hugely increases the estimate of risk to global economic wellbeing from climate change impacts such as fires, flooding, droughts, temperature rises and nature breakdown.
The world could fall short of food by 2050 due to falling crop yields, insufficient investment in agricultural research and trade shocks, according to Joe Biden’s special envoy for food security, Dr Cary Fowler. Fowler, who is also known as the “father” of the Svalbard Global Seed Vault, a global store of seeds for the most significant crops, said studies by agricultural economists showed the world needed to produce 50-60% more food by 2050 in order to feed its growing population. But crop yields rates were projected to decline by between 3-12% as a result of global heating.
Revealed: US climate denial group working with European far-right parties Representatives of Heartland Institute linking up with MEPs to campaign against environmental policies Helena Horton, Sam Bright and Clare Carlile Wed 22 Jan 2025 13.01 CET Last modified on Wed 22 Jan 2025 14.27 CET Climate science deniers from a US-based thinktank have been working with rightwing politicians in Europe to campaign against environmental policies, the Guardian can reveal.

The 29-year-old was arrested by City of London police after activists said they had cut the cables to insurance company offices in London, Leeds, Birmingham and Sheffield on Monday. In a press release, the group, which calls itself Shut the System, said it had targeted insurers “due to their critical role underpinning the fossil fuel economy through underwriting contracts and investments”.
As authorities declared 2024 the hottest on record, a key private sector climate alliance, the Glasgow Financial Alliance for Net Zero (GFANZ) abandoned a requirement that members be aligned to the Paris agreement. That was followed by a network of net zero asset managers suspending work, and deleting from its website its statement of commitments that members must adopt, after BlackRock, the biggest of them all, quit its ranks.
