Selon une alerte du réseau scientifique World Weather Attribution (WWA), ce mercredi 11 mai, cette fonte accélérée serait le résultat d’une vague de chaleur record entre le 15 et le 21 mai, qui a aussi touché l’Islande.

Des chercheurs ont mis au point un cadre qui permet de relier les émissions des entreprises à des dommages climatiques spécifiques.

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%.

Every December, people ask us how severe the year’s extreme weather events were. To answer this question, we’ve partnered with Climate Central to produce a report that reviews some of the most significant events and highlights findings from our attribution studies. It also includes new analysis looking at the number of dangerous heat days added by climate change in 2024 and global resolutions for 2025 to work toward a safer, more sustainable world.

People around the world suffered an average of 41 extra days of dangerous heat this year because of human-caused climate change. The figure comes from analysis done by researchers at World Weather Attribution and Climate Central. In 2024 climate records were shattered as heat across the globe made it likely to be the hottest year ever measured, with few countries spared fatal weather events.

Nouveau "TALK" sur LIMIT avec Davide Faranda Directeur de recherche CNRS (permanent) en sciences du climat au laboratoire LSCE de l’Université Paris-Saclay. Son expertise principale est l’attribution des événements météorologiques extrêmes au changement climatique. Il aborde la Science de l'attribution qui permet de définir si des événements extrêmes sont liés ou non au changement climatique d'origine anthropique, comprendre les ouragans et ce à quoi il faut se préparer.

The floods displaced more than 80,000 people, led to over 150,000 being injured and, on the 29th of May, to 169 fatalities with 44 people still missing (Governo do Estado de Rio Grande do Sul, 2024). Essential services were also disrupted, leaving 418,200 households without electricity and over a million consumer units without water. Dozens of municipalities lost telephone and internet services.

Greece, Italy, Spain, Portugal, France and Morocco experienced extreme heat in July 2024, causing at least 23 fatalities, widespread wildfires and bringing public life to a hold.

Le changement climatique d’origine humaine modifie la probabilité de survenue de nombreux phénomènes météorologiques. Et il est possible de relier l’effet d’un réchauffement sur le temps long à des événements isolés.

De extreme hittegolven deze maand in grote delen van de VS, Zuid-Europa en China zouden ‘vrijwel onmogelijk’ geweest zijn zonder de door de mens veroorzaakte klimaatverandering. Dat is de conclusie van het World Weather Attribution-initiatief (WWA).
