The activist and author of Here Comes the Sun discusses rapid advances in solar and wind power and how the US ceded leadership in the sector to its main rival

Il y a peu, la Commission de réglementation nucléaire (NRC) aux États-Unis a donné son accord pour la poursuite du projet Natrium de la société TerraPower. Cette société recevant le soutien de Bill Gates va pouvoir débuter la construction de la première unité de sa centrale à Kemmerer, dans l’état du Wyoming. Pour certains scientifiques, cette approbation arrive trop rapidement.

Much of today's sustainability discourse emphasizes efficiency, clean technologies, and smart systems, but largely underestimates fundamental physical constraints relating to energy-matter interactions. These constraints stem from the fact that Earth is a materially closed yet energetically open system, driven by the sustained but low power-density flux of solar radiation. This Perspective reframes sustainability within these axiomatic limits, integrating relevant timescales and orders of magnitude. We argue that fossil-fueled industrial metabolism is inherently incompatible with long-term viability, while post-fossil systems are surface-, materials-, and power-intensive. Long-term sustainability must therefore be defined not only by how much energy or material is used, but also by how it is used: favoring organic, carbon-based chemistry with limited reliance on purified metals, operating at low power density, and maintaining low throughput rates. Achieving this requires radical technological shifts toward l

For the first 300,000 years of human history, hunter-gathering Homo sapiens lived in fluid, egalitarian civilizations that thwarted any individual or group from ruling permanently. Then, around 12,000 years ago, that began to change.

The growth in US power demand is surging to its highest rate in decades, driven first by the electrification of oil and gas production and then by the build out of data centers. While still below the 5-10% growth seen in China, the world’s first “electrostate," the US power sector is experiencing rapid structural growth. The country is delivering more than a 3.5% annual power demand growth rate for the first time in several decades, potentially positioning the US as the world’s next “electrostate,” despite the strong oil and gas focus of the Trump administration.

A new report draws on internal company documents and other public records to comprehensively outline the fossil fuel industry’s decades-long campaign to mislead the public and avoid paying for their products’ harms.

Researchers say Aardvark Weather uses thousands of times less computing power and is much faster than current systemsA single researcher with a desktop computer will be able to deliver accurate weather forecasts using a new AI weather prediction approach that is tens of times faster and uses thousands of times less computing power than conventional systems.

That’s now how separation of powers works under the U.S. Constitution.

En Bretagne sur plusieurs plages, une association a collecté des milliers de "powerchips green". De quoi s'agit-il exactement ?

Author Adam Greenfield demonstrates the power of mutual aid and community networks, but they lack to power to fundamentally change societyIn his book Lifehouse, Adam Greenfield shows that ordinary people are capable of organising themselves and running their own lives even in the most difficult circumstances.

A new study suggests that the Gulf Stream was stronger during the last ice age due to more powerful winds, indicating that future changes in wind patterns could weaken the Gulf Stream, affecting European climate and North American sea levels. This research enhances our understanding of the Atlantic Meridional Overturning Circulation (AMOC) and its vulnerability to climate change.

Troquant son costume de financier en banque pour sa plume de Bon Pote, Thomas Wagner est une des figures emblématiques de la défense de l’environnement sur internet; il le dit lui même il "prendra sa retraite quand le réchauffement climatique sera de l’histoire ancienne » Sur les réseaux sociaux ou son blog, celui que l’on surnomme « l’influenceur du climat » livre un travail complet, sourcé et dense sur les sujets liés à l’actualité climatique : mieux comprendre le rapport du GIEC, comment faire son bilan carbone ou encore en apprendre plus sur l'histoire des voitures électriques, tout y passe. Par où commencer quand on veut s’informer sur la situation environnementale? Comment limiter son impact carbone au quotidien? Comment lutter contre l’eco-anxiété? J’espère que cet épisode vous donnera envie de découvrir davantage le travail de Thomas et je vous souhaite une bonne écoute

Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i
