Het KMI start het project 'Tales of Future Weather', dat klimaatwetenschap omzet naar concrete scenario’s van extreem weer zoals hitte, droogte en hevige neerslag. Zo worden de gevolgen van klimaatverandering tastbaar en kunnen we ons beter voorbereiden. Het project benadrukt dat burgers zelfredzamer moeten worden. "Er komt heel wat op ons af."

The Ocean is essential to life on Earth, regulates the climate, supports rich biodiversity, sustains livelihoods, and inspires cultures and societies. However, unregulated human impacts are putting the Ocean and its ability to contribute to humanity at risk. The Starfish Barometer is a new initiative launched on World Ocean Day (8 June 2025) to provide a concise, science-based annual overview of the multiple dimensions of the Ocean through the lens of its interdependence with humanity. Each year, the Starfish Barometer will present a carefully curated selection of Ocean-related developments, chosen for their global significance and grounded in the most up-to-date scientific evidence, intended for a broad non-specialist audience. Rather than offering an exhaustive review, it will spotlight key aspects, robust, evidence-based, and reflective of major developments of the year. The Starfish Barometer emphasizes the two-way relationship between humanity and the Ocean: we impact its future, and it shapes ours. Its

L’acide trifluoroacétique aussi appelé TFA est un tout petit PFAS, extrêmement stable et donc particulièrement persistant dans l’environnement. Comme il est très mobile et très soluble dans l’eau, il se retrouve dans tous les milieux. En outre, les procédés habituels de traitement de l’eau potable ne peuvent pas éliminer le TFA.

Pendant sept ans, la réalisatrice Helena Molin a filmé une douzaine d’adolescents à l’origine de la création, en 2018, du mouvement Fridays for Future. Un documentaire encensé par la critique.

Notre affaire à tous, Générations futures, Bloom et plusieurs particuliers attaquent l’Etat devant le tribunal administratif de Paris pour tenter de faire reconnaître sa responsabilité dans le scandale de la contamination aux polluants éternels.

Current energy projections often envision an expansion of nuclear capacities to decarbonize future energy systems. However, this contrasts with the historic and current status of the nuclear industry, marked by techno-economic challenges for both light-water and non-light-water reactor technologies. Regardless, projections of strong nuclear growth have persisted since the 1970s. This paper investigates the “nuclear energy paradox” which shows the recurring divergence between historical projections and actual developments. A data compilation of long-term energy projections from international organizations such as the IAEA and the IEA as well as energy system models like GCAM and MESSAGE, as used in the IPCC, reveal a recurring pattern of high-growth projections for nuclear power. Such projections often rest on techno-economic assumptions such as substantial cost reductions. We propose the concept of nuclear imaginaries to show that these assumptions are embedded into techno-economic visions of nuclear power de

Scenarios serve as a critical tool in climate change analysis, enabling the exploration of future evolution of the climate system, climate impacts, and the human system (including mitigation and adaptation actions). This paper describes the scenario framework for ScenarioMIP as part of CMIP7. The design process has involved various rounds of interaction with the research community and user groups at large. The proposal covers a set of scenarios exploring high levels of climate change (to explore high-end climate risks), medium levels of climate change (anchored to current policy), and low levels of climate change (aligned with current international agreements). These scenarios follow very different trajectories in terms of emissions, with some likely to experience peaks and subsequent declines in greenhouse gas concentrations in this century. An important innovation is that most scenarios are intended to be run, if possible, in emission-driven mode, providing a better representation of the Earth system uncert

Climate models show considerable discrepancies in their future projections around the Atlantic, mainly due to uncertainties in the fate of the Atlantic Meridional Overturning Circulation (AMOC). Climate models suggest a reduction in AMOC strength of 32 ± 37% by 2100 (90% probability, Shared Socioeconomic Pathways 2-4.5 scenario, Coupled Model Intercomparison Project Phase 6). To refine this estimate and reduce its uncertainty, we use four different observational constraint methods. The best one, which provides the lowest leave-one-out error, integrates a large set of observable variables using ridge-regularized linear regression—a method unusual in climate science. It gives an estimate of the AMOC slowdown of 51 ± 8% (90% probability), i.e., a weakening ∼ 60% stronger than suggested by the multimodel mean. This refinement mainly results from correcting a bias in South Atlantic surface salinity, consistent with recent studies emphasizing its role in the proximity to an AMOC tipping point. This more substantial

Attaquées par les populistes en France et en Europe, les règlementations ciblant les pesticides, les Pfas ou les particules fines sont pourtant vitales, rappelle le porte-parole de l’association Générations futures, François Veillerette.

Le texte a été modifié par rapport à sa première mouture adoptée en juillet 2025, qui avait suscité l’indignation, avant que le Conseil constitutionnel censure l’article réintroduisant l’acétamipride, un pesticide de la famille des néonicotinoïdes.
