Despite mounting evidence of global warming’s costs, the Trump administration has made multiple moves to avoid tracking climate-related economics.

2024 was the first single year to surpass the 1.5°C global warming threshold – now scientists predict that a year above 2°C is possible in the near future

Kiev dit avoir détruit plus de 40 avions militaires russes dans plusieurs aérodromes russes, dont un situé à plus de 4 000 kilomètres du front.

In 2024 hadden banken en andere vermogensbeheerders beleggingen ter waarde van meer dan 33 miljard dollar in de grootste oliemaatschappijen die verantwoordelijk zijn voor 18% van de jaarlijkse wereldwijde uitstoot van broeikasgassen via zogenaamde “groene” fondsen die zogenaamd een duurzame economie bepleiten, zo blijkt uit een onderzoek van Voxeurop en The Guardian. De betreffende fondsen worden op de markt gebracht door grote spelers zoals JP Morgan, DWS/Deutsche Bank en BlackRock.

Antarctica's remote and mysterious current has a profound influence on the climate, food systems and Antarctic ecosystems. Can we stop it weakening by 2050?

The Antarctic Circumpolar Current (ACC) is the world's strongest ocean current and plays a disproportionate role in the climate system due to its role as a conduit for major ocean basins. This current system is linked to the ocean's vertical overturning circulation, and is thus pivotal to the uptake of heat and CO2 in the ocean. The strength of the ACC has varied substantially across warm and cold climates in Earth's past, but the exact dynamical drivers of this change remain elusive. This is in part because ocean models have historically been unable to adequately resolve the small-scale processes that control current strength. Here, we assess a global ocean model simulation which resolves such processes to diagnose the impact of changing thermal, haline and wind conditions on the strength of the ACC. Our results show that, by 2050, the strength of the ACC declines by ∼20% for a high-emissions scenario. This decline is driven by meltwater from ice shelves around Antarctica, which is exported to lower latit

Les universités américaines font partie depuis quelques mois des cibles privilégiées de Donald Trump, qui les voit comme des foyers d’antisémitisme et de «wokisme». Le ralentissement de la délivrance de papiers aux étudiants étrangers pourrait durablement les fragiliser.

La marque du groupe Nestlé voit sa consommation chuter de 24 % en avril par rapport au même mois l’année dernière, selon des données révélées par France Info ce mardi 27 mai.

Earth’s albedo (reflectivity) declined over the 25 years of precise satellite data, with the decline so large that this change must be mainly reduced reflection of sunlight by clouds. Part of the cloud change is caused by reduction of human-made atmospheric aerosols, which act as condensation nuclei for cloud formation, but most of the cloud change is cloud feedback that occurs with global warming. The observed albedo change proves that clouds provide a large, amplifying, climate feedback. This large cloud feedback confirms high climate sensitivity, consistent with paleoclimate data and with the rate of global warming in the past century.

L'intelligence artificielle (IA) est de plus en plus utilisée dans le domaine scientifique. Son utilisation n'est pas neuve, mais son usage connait une évolution fulgurante. Ce succès est dû au développement des modèles neuronaux de type "transformers", et plus spécifiquement des Large Language Models (LLMs) comme BERT (Google) ou ChatGPT (OpenAI).
