Monthly global surface air temperature anomalies (°C) relative to 1850–1900 from January 1940 to June 2024, plotted as time series for all 12-month periods spanning July to June of the following year. The 12 months from July 2023 to June 2024 are shown with a thick red line, while all other 12-month periods are shown with thin lines shaded according to the decade, from blue (1940s) to brick red (2020s).

Simultaneous harvest failures across major crop-producing regions are a threat to global food security. Concurrent weather extremes driven by a strongly meandering jet stream could trigger such events, but so far this has not been quantified. Specifically, the ability of state-of-the art crop and climate models to adequately reproduce such high impact events is a crucial component for estimating risks to global food security. Here we find an increased likelihood of concurrent low yields during summers featuring meandering jets in observations and models. While climate models accurately simulate atmospheric patterns, associated surface weather anomalies and negative effects on crop responses are mostly underestimated in bias-adjusted simulations. Given the identified model biases, future assessments of regional and concurrent crop losses from meandering jet states remain highly uncertain. Our results suggest that model-blind spots for such high-impact but deeply-uncertain hazards have to be anticipated and acc

Overexploitation and habitat loss pose extinction threats for migratory fish, birds and others, worldwide

New research shows the company’s scientists were as “skillful” as independent experts in predicting how the burning of fossil fuels would warm the planet and bring about climate change.

Het affakkelen van gas in de fossiele brandstofindustrie klom vorig jaar naar het hoogste niveau sinds 2019, ondanks de groeiende internationale druk om de vervuilende praktijk aan banden te leggen.

Summary for Policymakers. A Report of the Intergovernmental Panel on Climate Change

Environ 500 personnes ont participé dimanche à une marche pour le climat à Bruxelles, a indiqué l’organisation à l’origine de l’évènement Rise For Climate Belgium. Par le biais de cet évènement intitulé "Touche pas à mon futur", l’organisation espère inciter la société civile à s’opposer à l’éventuelle réduction des politiques climatiques et aux politiques d’austérité, alors que l’extrême droite monte un peu partout en Europe.

Historical responsibility for climate change is radically shifted when colonial rule is taken into account, Carbon Brief analysis reveals.

Since the Paris Agreement in 2016, the world’s 60 largest private banks financed fossil fuels with USD $6.9 trillion. Nearly half – $3.3 trillion – went towards fossil fuel expansion. In 2023, banks financed $705 billion in fossil fuel financing with $347 billion going to fossil fuel expansion alone.

Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC). Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles. We follow methods as close as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report. We compile monitoring datasets to produce estimates for key climate indicators related to forcing of the climate system: emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activit
