Climate models simulate a wide range of 21st century warming for a given forcing scenario. Constraining this uncertainty is a central challenge in climate science because of its implications for climate policy and adaptation. The Transient Climate Response (TCR) is a key idealized metric used to quantify future warming in response to an exponentially increasing CO2 concentration. Climate models span a range of 1.3–3 K for TCR. In attempts to constrain this range, emergent constraints on TCR based on historical temperature trends consistently pointed towards TCR values at the lower end of the range of models. However, recent evidence from trends in the short-wave and long-wave components of Earth's energy imbalance (EEI) at the top-of-atmosphere suggests that models with higher TCR lie closer to the observed EEI trends. Here, we reconcile this discrepancy and provide a revised range for TCR of 1.9–2.6 K. Using a statistical variability-filtering approach, we show that previous temperature-based constraints we

European scientists warn of consequences for weather patterns, the global climate and marine life

Climate scientists warn of unprecedented Antarctic heatwave, with temperatures 20C above normal. Loss of sea ice threatens marine life and penguins.

Cet article rapporte la difficulté du secteur manufacturier en Grande Bretagne à faire face à l’augmentation du cout de l'énergie. Dans l'ombre de cet article apparait ce qui sera la réalité à un moment donné, sans pétrole bon marché, l'industrie manufacturière ne peut pas fonctionner dans les conditions actuelles. Le contrat social sera rompu et il faudra réinventer une manière de vivre ensemble. La situation en Grande Bretagne est peut-être exacerbée par le Brexit et la situation insulaire mais elle est l'avant-poste de ce qui attend une bonne part du monde industrialisé, à moins de relancer le charbon avec toutes les conséquences sur le dérèglement climatique et la santé des personnes que nous connaissons.

Une solution crédible et tangible pour réduire les émissions de CO2 » et « lutter contre le changement climatique ». C’est ainsi que TotalEnergies célébrait, en août 2025, le lancement opérationnel de Northern Lights – « aurores boréales » en anglais. Cette entreprise norvégienne, détenue par le groupe français et deux autres majors du pétrole (la norvégienne Equinor et l’anglo-néerlandaise Shell), gère le plus gros projet de captage et de stockage du carbone (CCS, carbon capture and storage) en Europe, et le seul en activité aujourd’hui. Les industriels belges espèrent bien pouvoir s’y associer pour y enfouir leur CO2. Mais les promesses semblent loin aujourd’hui. La technologie du CCS consiste à stocker le CO2 sous terre pour l’empêcher de réchauffer l’atmosphère. Elle est très critiquée par les écologistes pour son coût exorbitant, et parce qu’elle entretient la dépendance aux énergies fossiles. Mais grâce à un intense lobbying, le CCS s’est imposé comme la priorité politique de l’Union européenne (UE) pou

La construction d'un datacenter en Utah a entrainé une opposition farouche des habitants. La course à l'IA repose la question de l'équilibre entre technologie et ressources limitées en eau, en terres arables et terres rares, en électricité. De nombreux datacenter vont utiliser des énergies fossiles.

Sixty-five million people will die from pollution caused by nuclear energy and weapons programs built before 1989, according to a report published earlier this year by a European scientific committee. The research, from the European Committee on Radiation Risk (ECRR), raises doubts about previous estimates of the risk posed to humans from exposure to radiation from nuclear power and weapons. The study by the ECRR, based on a risk-assessment model developed over the past five years, challenges previous assumptions about the safety of even minimum exposure to low-level radiation.

Welcome to the Global Climate Highlights 2025 report, compiled by the Copernicus Climate Change Service (C3S). The Global Climate Highlights 2025 report provides authoritative climate data and concise insight on a global scale about 2025's climate conditions, covering surface and sea surface temperature, heat stress, sea ice extent in the Arctic and Antarctic, among others.

A new international analysis published in Advances in Atmospheric Sciences on 9 January finds that the Earth's ocean stored more heat in 2025 than in any year since modern measurements began. The finding is the result of a major international collaboration led by the Institute of Atmospheric Physics at the Chinese Academy of Sciences, involving more than 50 scientists from 31 research institutions worldwide. The 2025 heat increase was 23 Zetta Joules (23,000,000,000,000,000,000,000 Joules of energy), which is equivalent to ~37 years of global primary energy consumption at the 2023 level (~620 Exa Joules per year). The assessment combines data from major international data centers and independent research groups, including three observational products (Institute of Atmospheric Physics at the Chinese Academy of Sciences; Copernicus Marine; and NOAA/NCEI) and an ocean reanalysis (CIGAR-RT) from three continents: Asia, Europe, and America. These groups confirm that the 2025 ocean heat content (OHC) reached the h
