Le géant pétrolier français TotalEnergies n'a pas encore démarré la production dans son projet contesté d'oléoduc en Afrique de l'Est mais les fragiles écosystèmes en Ouganda en souffrent déjà, avec des effets "dévastateurs" sur l'environnement, dénonce vendredi une activiste d'une ONG ougandaise. La région du lac Albert abrite des ressources pétrolières estimées à plus d'un milliard de barils que le géant pétrolier veut exploiter en partenariat notamment avec le groupe pétrolier chinois CNOOC à travers les projets Tilenga et EACOP (East African Crude Oil Pipeline).

La Cour européenne des droits de l'Homme, siégeant en Grande Chambre, a conclu mardi à de multiples violations de la Convention par la Russie, dans le cadre de son occupation de la Crimée depuis 2014.

De natuurherstelwet, een van de laatste grote wetgevende luiken van de Europese Green Deal, is dan toch goedgekeurd. Twee jaar na het voorstel heeft de Oostenrijkse minister van Milieu alsnog voor gestemd, waardoor de nodige meerderheid van de lidstaten is gevonden. Opvallend: binnen de Oostenrijkse federale regering dreigt nu wel een politieke crisis.

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.

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

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.

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information. Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total. The findings of this study provide baseline data for ocean plastic mass balance exercises, and assist in prioritizing future plastic debris monitoring and mitigation strategies. Rivers provide a m

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.

Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i

Le Brexit, la toute-puissance de la Big Tech, les cryptomonnaies, les fake news et même la hausse des prix du café : tout s’explique par le “quantitative easing”, affirme “The New Statesman”. L’hebdomadaire britannique choisit de faire sa une sur les risques et les limites de cette politique monétaire.

Alors que le monde se prépare à la 26e session de la Conférence des Parties (COP 26) à la Convention-cadre des Nations unies sur les changements climatiques, qui se tiendra au Royaume-Uni dans le courant de cette année, l’action climatique ne doit pas négliger les communautés touchées par les conflits. A ce titre, l’Irak mérite toute notre attention.

Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estim

The State of the Cryosphere 2023 – Two Degrees is Too High report shows that all of the Earth’s frozen parts will experience irreversible damage at 2°C of global warming, with disastrous consequences for millions of people, societies, and nature. Confirming that just 2°C of global warming will trigger irreversible loss to Earth’s ice sheets, mountain glaciers and snow, sea ice, permafrost, and polar oceans, it updates the latest science and highlights the global impacts from cryosphere loss.
