Le climat est la distribution statistique des conditions de l’atmosphère terrestre dans une région donnée pendant une période donnée. L’étude du climat est la climatologie. Elle se distingue de la météorologie qui désigne l’étude du temps dans l’atmosphère à court terme et dans des zones ponctuelles. source : wikipedia

Developing countries urge biggest polluters to act as Trump’s return to the White House heightens geopolitical turmoil
Human-driven ocean warming is increasingly overwhelming El Niño, La Niña, and other natural climate patterns.
Concerns raised as $10bn Bezos Earth Fund halts funding for Science Based Targets initiative, which monitors companies’ decarbonisation
An international group of scientists, led by King's College London, has revealed how continued global warming will lead to more parts of the planet becoming too hot for the human body over the coming decades. the amount of landmass on our planet that would be too hot for even healthy young humans (18 to 60-year-olds) to keep a safe core body temperature will approximately triple (to 6%)—an area almost the size of the US—if global warming reaches 2°C above the preindustrial average.
It’s not just Florida and California — from poisoned water supplies to infrastructure issues to polar vortices, Holly Baxter speaks to experts about why the entire U.S. is being threatened by climate change, and why you can’t just move to Vermont to escape it
Members reportedly sought access to IT systems at agency that Project 2025 has called ‘harmful to US prosperity’
Prof James Hansen says pace of global heating has been significantly underestimated, though other scientists disagree
Scientists say unusually mild temperatures linked to low-pressure system over Iceland directing strong flow of warm air towards north pole
The USDA has begun removing references to climate change on its webpages and sites, including the U.S. Forest Service website.
Some scientists fear the risk of a collapse to warm Atlantic currents has not been taken seriously.

Forest service website among many sites affected as agencies scramble to comply with president’s orders
The directive follows President Trump's orders reversing climate policies.
Key resources for environmental data and public health have already been taken down from federal websites, and more could soon vanish as the Trump administration works to scrap anything that has to do with climate change, racial equity, or gender identity.
Human-caused climate change increased the likelihood and intensity of the hot, dry and windy conditions that fanned the flames of the recent devastating Southern California wildfires, a scientific study found. But the myriad of causes that go into the still smoldering fires are complex, so the level of global warming's fingerprints on weeks of burning appears relatively small compared to previous studies of killer heat waves, floods and droughts by the international team at World Weather Attribution. Tuesday's report, too rapid for peer-review yet, found global warming boosted the likelihood of high fire weather conditions in this month's fires by 35% and its intensity by 6%.
A rule known as the endangerment finding requires the E.P.A. to regulate greenhouse gases. It has proved resilient against earlier attacks.
Previous health impact assessments of temperature-related mortality in Europe indicated that the mortality burden attributable to cold is much larger than for heat. Questions remain as to whether climate change can result in a net decrease in temperature-related mortality. In this study, we estimated how climate change could affect future heat-related and cold-related mortality in 854 European urban areas, under several climate, demographic and adaptation scenarios. We showed that, with no adaptation to heat, the increase in heat-related deaths consistently exceeds any decrease in cold-related deaths across all considered scenarios in Europe. Under the lowest mitigation and adaptation scenario (SSP3-7.0), we estimate a net death burden due to climate change increasing by 49.9% and cumulating 2,345,410 (95% confidence interval = 327,603 to 4,775,853) climate change-related deaths between 2015 and 2099. This net effect would remain positive even under high adaptation scenarios, whereby a risk attenuation of 50%
The only publication for climate action, covering the environment, biodiversity, net zero, renewable energy and regenerative approaches. It’s time for The New Climate.
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. MEPs have been accused of “rolling out the red carpet for climate deniers” to give them a platform in the European parliament, amid warnings of a “revival of grotesque climate denialism”.
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,”
Thousands of Greenland's crystal-clear blue lakes have turned a murky brown thanks to global warming — and the worst part is that they've started emitting carbon dioxide. Record heat and rain in 2022 pushed the lakes of West Greenland past a tipping point, so rather than absorbing carbon dioxide (CO₂), they began to emit it into the atmosphere, according to a new study.
