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.

Climate change is causing measurable harm globally1,2. Political and legal efforts seek to link these damages with specific emissions, including in discussions of loss and damage (L&D)3,4; however, no quantitative definition of L&D exists5,6, nor is there a framework to link past and future emissions from specific sources to monetized, location-specific damages. Here we develop such a framework, which is integrated with recent efforts to estimate the social cost of carbon7. Using empirical estimates of the non-linear relationship between temperature and aggregate economic output, we show that future damages from past emissions—one component of L&D—are at least an order of magnitude larger than historical damages from the same emissions. For instance, one tonne of CO2 emitted in 1990 caused US$180 in discounted global damages by 2020 ($40–530) and will cause an additional $1,840 through 2100 ($500–5,700). Thus, settling debts for past damages will not settle debts for past emissions. In other illustrative esti

Le philosophe de l'environnement Rupert Read dit à Ella Whelan la panéliste Moral Maze pourquoi nous ne pourrons peut-être plus profiter du même niveau de vie pour le bien de la planète et des générations futures.

La réforme du règlement européen sur la sécurité des produits chimiques (REACH) figure à l'agenda de la Commission européenne depuis 2020. Cependant, une forte opposition de l'industrie, y compris tout au long de l'année 2025 comme le révèle ce rapport, a occulté l'urgence sanitaire et environnementale de lutter contre les substances chimiques nocives. La manipulation de l'industrie et son accès privilégié aux plus hautes instances de la Commission, conjugués à l'hostilité actuelle de l'UE envers les nouvelles réglementations environnementales et à sa frénésie de déréglementation, semblent avoir irrémédiablement compromis un objectif clé du Pacte vert pour l'Europe.

Donald Trump a salué mardi un accord pour construire une nouvelle raffinerie de pétrole avec le soutien du géant indien de l'énergie Reliance industries, dans un contexte de frictions récurrentes avec New Delhi. Cette nouvelle structure sera construite par l'entreprise America First Refining dans l'Etat du Texas, dans le sud des Etats-Unis. "Il s'agit d'un accord historique de 300 milliards de dollars, le plus important de l'histoire des Etats-Unis", a écrit le président américain sur Truth Social, sans donner plus de détails.

The Global Environment Outlook, Seventh Edition: A Future We Choose, the product of 287 multi-disciplinary scientists from 82 countries, is the most comprehensive scientific assessment of the global environment ever carried out.

The latest Lancet Countdown report warns that health impacts of climate change are worsening, with millions dying needlessly each year due to fossil fuel dependence, growing greenhouse gas emissions, and failure to adequately adapt. As some countries and companies rollback on climate commitments, local and grassroots leadership is building momentum for a healthier future.​ The report represents the work of 128 experts from 71 institutions, monitoring progress across 57 indicators – from heat-related deaths to bank lending to fossil fuels – providing the most comprehensive assessment yet of the links between climate change and health.

Notre ami Luke Kemp, chercheur au Centre pour l'étude du risque existentiel à l'Université de Cambridge (UK), a publié le livre Goliath’s Curse, the History and Future of Societal Collapse (Penguin, July 2025, 580 pages), qui sera édité en français par Albin Michel au printemps 2026. Cette « malédiction de Goliath » est le meilleur livre sur l’effondrement systémique mondial depuis dix ans, tant par la vision multidisciplinaire qu’il présente que par sa complétude et par son érudition.

US demand to own Greenland leaves little scope for compromise, and forcing the issue would entail end of Nato Greenland, with a population of fewer than 57,000, might not seem to be the territory on which the future of the relationship between Europe and the US, the viability of Nato as the world’s most successful defence alliance, or even the fractured relations between the UK and Europe would be determined. But battlefields are sometimes the product of chance, rather than choice. It now feels as if Donald Trump’s threat to impose 10% tariffs on eight fellow Nato states for sending troops last week to support Greenland’s sovereignty may be one of those clarifying moments in which Europe had no option. Successive European leaders condemned Trump’s blackmail and intimidation on Sunday and they sounded as if they meant it.
