Les LLM sont devenus les pommes de terre de l'intelligence artificielle : essentiels, abondants, mais finalement peu différenciants. OpenAI l'a compris et achète la friteuse et le chef : Windsurf pour l'atelier logiciel, Ive pour l'esthétique et l'objet.

Considéré par ses partisans comme un visionnaire, Elon Musk incarne le modèle du « leader gourou ». Mais la chute des résultats de Tesla et ses prises de position controversées mettent en lumière les limites d’un leadership fondé sur le culte de la personnalité.

Ce soir-là, quelque huit minutes après son lancement de la base de Boca Chica, au Texas, le deuxième étage de la mégafusée Starship, lanceur lourd fabriqué par Space Exploration Technologies Corporation (SpaceX, l’entreprise d’Elon Musk), se désintégrait dans la thermosphère à 146 kilomètres d’altitude, en raison d’un incident technique, provoquant un spectacle semblable à une pluie de météorites.

... An “acid” test of our interpretation will be provided by the 2025 global temperature: unlike the 1997-98 and 2015-16 El Ninos, which were followed by global cooling of more than 0.3°C and 0.2°C, respectively, we expect global temperature in 2025 to remain near or above the 1.5°C level. Indeed, the 2025 might even set a new record despite the present weak La Nina. There are two independent reasons. First, the “new” climate forcing due to reduction of sulfate aerosols over the ocean remains in place, and, second, high climate sensitivity (~4.5°C for doubled CO2) implies that the warming from recently added forcings is still growing significantly.

Sudden cut in pollution in 2020 meant less shade from sun and was ‘substantial’ factor in record surface temperatures in 2023, study finds

Een netwerk van burgers dat een vluchtelingengezin rechtstreeks, actief en lokaal begeleidt tijdens hun integratietraject, dat is het uitgangspunt van Community Sponsorship. Het project van Caritas en Fedasil is net uit de pilootfase. ‘Op deze manier hebben vluchtelingen meteen een sociaal vangnet.’

Une plainte contre le régulateur aérien américain a été déposée au tribunal fédéral de Washington par plusieurs organisations environnementales qui s’inquiètent de la pollution engendrée par l’explosion de la fusée de SpaceX le 20 avril.

Äerdchëff, le premier “earthship” (géonef) du Luxembourg, est sorti de terre à Redange. Un bâtiment quasiment autonome en énergie et en eau, en partie construit en utilisant certains types de déchets. Le gouvernement luxembourgeois veut en faire un projet pilote.

Are you a 'subject', a 'consumer'… or a 'citizen'? The authors Jon Alexander and Ariane Conrad argue that our societies need a new narrative, and it starts by ditching the stories sold by authoritarianism and consumerism.

Today’s oceans are a tumult of engine roar, artificial sonar and seismic blasts that make it impossible for marine creatures to hunt or communicate. We could make it stop, so why don’t we?

As climate crisis allows new maritime routes to be used, sooty shipping emissions accelerates ice melt and risk to ecosystems

Water vapor is Earth’s most abundant greenhouse gas. It’s responsible for about half of Earth’s greenhouse effect — the process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. Greenhouse gases keep our planet livable. Without them, Earth’s surface temperature would be about 59 degrees Fahrenheit (33 degrees Celsius) colder. Water vapor is also a key part of Earth’s water cycle: the path that all water follows as it moves around Earth’s atmosphere, land, and ocean as liquid water, solid ice, and gaseous water vapor.

Over 25 million tonnes of CO2 – equivalent to the total CO2 emissions of Denmark¹ – are exempt from the EU’s proposed carbon price for shipping, a new Transport & Environment (T&E) study shows. Arbitrary exemptions of ships such as those servicing oil and gas facilities, as well as yachts, will undermine the EU’s shipping law and let millions of tonnes of emissions off the hook, says T&E.

The U.S. nuclear power regulator last month suspended the shipment of radioactive materials and a hydrogen isotope used in reactors to China's largest state-owned nuclear company, CGN, reflecting Washington's concerns about the country's buildup of atomic weapons.

Failing, heavily subsidized private oil companies enjoy the profits of oil extraction while the rest of us pay in tax dollars, human rights abuses, and an unlivable climate. Oil and gas companies are a political structure: they possess private, authoritarian dominion over the pace and volume of oil and gas production, and thus of important determinants of global emissions. These emissions and their consequences do not respect any sort of public/private distinction, nor borders, nor the rights to clean air or clean water.

Cette déclaration, inscrite dans un courant écocentriste qui considère que l’homme n’est plus le «maître » de la Nature, mais une espèce parmi d’autres, implique de reconnaître des valeurs et une dignité intrinsèque à la rivière Magpie, car elle devient dorénavant un sujet de droit.

How is it possible to own land? The current pattern of ownership and control of land lies at the heart of many of our biggest dysfunctions: the collapse of wildlife and ecosystems, the exclusion and marginalization of so many people, the lack of housing in many cities—indeed, in many parts of the world—the lack of public space in cities, our exclusion from the countryside. The pattern of land ownership underlies all of these massive issues, and indeed of many more. Yet we rarely question it.
