Scientists know how to alter our atmosphere to try and fix climate change, but doing so could bring other potential unintended impacts

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

The system of ocean current that moves heat in the Atlantic Ocean plays a key role in regulating climate. Today’s monitoring of it may be discontinued...

Projections of near-term climate change are a potential research tool. However, for that tool to be most useful, the physical basis for a prediction must be made clear. The basis for our projection of record 2026 global temperature is high climate sensitivity, with its implication that aerosol cooling was still increasing during the period 1970-2005. One consequence, global sea surface warming, already has important effects. Causes of climate change must be understood for policy purposes. Figures in this post and our recent papers are continually updated on our website.[1] We are also now on Substack[2].

The Global Justice Project is a collective research initiative developed by the World Inequality Lab. Combining comparative historical data series from the World Inequality Database with global input-output tables, environmental accounts, labour force surveys and other sources, the project explores what a just distribution of socio-economic and environmental resources could look like at the global level from 2025 to 2100 – both between and within countries – in a way that is compatible with planetary boundaries. The project partly builds on the analysis and proposals set out in Thomas Piketty’s Brief History of Equality, extending them into a broader and more comprehensive global framework. The Global Justice Project is now available to explore on a dedicated website, that includes an interactive tool to explore the distributional pathways and climate scenarios behind the report.

The Global Justice Report offers a hopeful bargain: tax extreme wealth and replace consumer excess with social and economic security for all

Vagues de chaleur marines en hausse, fonte du budget carbone... Ces indicateurs qui explosent témoignent du rythme sans précédent atteint par le réchauffement planétaire, estiment 73 chercheurs dans un rapport publié le 11 juin.

- Artificial intelligence could pose a "more urgent" threat to humanity than climate change, AI pioneer Geoffrey Hinton told Reuters in an interview on Friday. Geoffrey Hinton, widely known as one of the "godfathers of AI", recently announced he had quit Alphabet, opens new tab after a decade at the firm, saying he wanted to speak out on the risks of the technology without it affecting his former employer.

Global effort needed to limit effects of pollution, industrial fishing and climate crisis, World Ocean Assessment says

Les scénarios socio-économiques et les niveaux de réchauffement planétaire qui en résultent structurent la compréhension des chaines de causalité entre les émissions de gaz à effet de serre, le contrôle de la pollution atmosphérique, les changements d’usage des terres, la réponse du système Terre, les facteurs climatiques générateurs d’impacts, l’exposition, la vulnérabilité, les réponses d’adaptation, et les risques liés au climat.
