While the term “Anthropocene” is well established across scientific disciplines and social spheres, interpretations are diverse. Taking account of the 2024 rejection by a geological commission to accept the Anthropocene as a geological epoch and the related scientific debate, here we offer a future-oriented perspective from the viewpoint of Earth system science. We describe different pathways in the Anthropocene up to the year 3,000, systematically characterizing them according to impacts and causes. We discuss the enormous global consequences of anthropogenic pressures on the Earth system and quantify the corresponding long-term commitment to change. Regarding the causes, we conservatively explore best-case and middle-of-the road emission scenarios, in combination with climate sensitivities drawn from within the IPCC likely range. We also discuss implications for Earth system resilience that could result in what we call worst case scenarios for Anthropocene outcomes. We conclude that, beyond the slow pace of

The Atlantic meridional overturning circulation (AMOC) is an important tipping element in the climate system. There is a large uncertainty whether the AMOC will start to collapse during the century under future climate change, as this requires long climate model simulations which are not always available. Here, we analyze targeted climate model simulations done with the Community Earth System Model (CESM) with the aim to develop a physics-based indicator for the onset of an AMOC tipping event. This indicator is diagnosed from the surface buoyancy fluxes over the North Atlantic Ocean and is performing successfully under quasi-equilibrium freshwater forcing, freshwater pulse forcing, climate change scenarios, and for different climate models. An analysis consisting of 25 different climate models shows that the AMOC could begin to collapse by 2063 (from 2026 to 2095, to percentiles) under an intermediate emission scenario (SSP2-4.5), or by 2055 (from 2023 to 2076, to percentiles) under a high-end emission scenar

Recent simulations using the Community Earth System Model (CESM) indicate that a tipping event of the Atlantic Meridional Overturning Circulation (AMOC) would cause Europe to cool by several degrees. This AMOC tipping event was found under constant pre-industrial greenhouse gas forcing, while global warming likely limits this AMOC-induced cooling response. Here, we quantify the European temperature responses under different AMOC regimes and climate change scenarios. A strongly reduced AMOC state and intermediate global warming (C, Representative Concentration Pathway 4.5) has a profound cooling effect on Northwestern Europe with more intense cold extremes. The largest temperature responses are found during the winter months and these responses are strongly influenced by the North Atlantic sea-ice extent. Enhanced North Atlantic storm track activity under an AMOC collapse results in substantially larger day-to-day temperature fluctuations. We conclude that the (far) future European temperatures are dependent o

Il est loin le temps où on pouvait faire de la publicité pour tout. Aujourd’hui, pas de pub pour le tabac, les armes ou l’alcool. Pourrait-on aller plus loin et interdire la promotion des produits fortement polluants ? Et peut-être même interdire la publicité ?

Microplastics are ubiquitous environmental contaminants for which there are documented human exposures, but there is a paucity of research evaluating their impacts on human health. We conducted a rapid systematic review using the “Navigation Guide” systematic review method. We searched four databases in July 2022 and April 2024 with no restriction on the date.

Mercredi 5 juin, à l’occasion de la Journée mondiale de l’environnement, António Guterres s’est exprimé au sujet de la gravité de la crise climatique et, dans ce cadre, il a fait une proposition singulière : interdire les publicités pour les compagnies du secteur des énergies fossiles.

L'autorité britannique de la publicité (ASA) a interdit mercredi les publicités publiées en juillet dernier sur Google des compagnies aériennes Air France-KLM, Lufthansa et Etihad Airways, au motif qu'elles contenaient des affirmations environnementales jugées "trompeuses".

Depuis quelques jours, une campagne publicitaire portée par l’Agence de la transition écologique (Ademe) autour de la sobriété provoque l’ire des acteurs du commerce, entraînant des désaccords jusqu’au sein du gouvernement.

L’Agence de la transition écologique a lancé un spot publicitaire contre la surconsommation. Une campagne validée par Christophe Béchu, mais fortement décriée par des ministres et des commerçants.
