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

This year elections are taking place across the globe, covering almost half of the world’s population. It is also likely to be, yet again, the hottest year recorded as the climate crisis intensifies. The Guardian asked young climate activists around the world what they want from the elections and whether politics is working in the fight to halt global heating.

Une analyse menée par les services du renseignement et de la sécurité montre que la désinformation est une menace réelle à l'approche des élections, indique jeudi le centre de crise (NCCN) dans un communiqué de presse.

L’augmentation des niveaux de CO2 atmosphérique actuelle est 10 fois plus rapides qu’à tout moment au cours des 50 000 dernières années.

Près de 80% des scientifiques du Giec interrogés par le «Guardian» pensent que la température sur Terre aura augmenté d’au moins 2,5°C au cours de ce siècle par rapport à la fin du XIXe.

Après la découverte de fortes concentrations de virus H5N1 dans le lait de vaches contaminées par la grippe aviaire aux Etats-Unis, l'OMS a recommandé vendredi d'appliquer des mesures de sécurité alimentaire de bon sens comme l'usage de lait pasteurisé.

Over the past 50 years, humans have extracted the Earth’s groundwater stocks at a steep rate, largely to fuel global agro-economic development. Given society’s growing reliance on groundwater, we explore ‘peak water limits’ to investigate whether, when and where humanity might reach peak groundwater extraction. Using an integrated global model of the coupled human–Earth system, we simulate groundwater withdrawals across 235 water basins under 900 future scenarios of global change over the twenty-first century. Here we find that global non-renewable groundwater withdrawals exhibit a distinct peak-and-decline signature, comparable to historical observations of other depletable resources (for example, minerals), in nearly all (98%) scenarios, peaking on average at 625 km3 yr−1 around mid-century, followed by a decline through 2100. The peak and decline occur in about one-third (82) of basins, including 21 that may have already peaked, exposing about half (44%) of the global population to groundwater stress. Most

Een gelekte nota toont de prioriteiten van de EU-lidstaten voor de nieuwe Europese Commissie na de komende Europese verkiezingen. De Bond Beter Leefmilieu is formeel: “De EU-regeringsleiders willen elke inzet voor de biodiversiteit- en klimaatcrisis overboord gooien”.

In een historische uitspraak heeft het Europees Hof voor de Rechten van de Mens vastgesteld dat landen die nalatig zijn in het uitvoeren van effectief klimaatbeleid, de mensenrechten van hun burgers schenden.

6 Europese lidstaten, onder leiding van de Oostenrijkse minister van Landbouw, vragen versoepelingen van de ontbossingswet die eind dit jaar van kracht wordt. Die moet verhinderen dat nog producten op de Europese markt komen waarvoor bos is gesneuveld. Hun vraag wordt vandaag in Brussel besproken op de bijeenkomst van Europese Landbouwministers.
