Do we really want to play dice with our planet?

Nearly every indicator of climate change is flashing red. But we still hold the tools available to bring the planet back into balance

Cet article rapporte la difficulté du secteur manufacturier en Grande Bretagne à faire face à l’augmentation du cout de l'énergie. Dans l'ombre de cet article apparait ce qui sera la réalité à un moment donné, sans pétrole bon marché, l'industrie manufacturière ne peut pas fonctionner dans les conditions actuelles. Le contrat social sera rompu et il faudra réinventer une manière de vivre ensemble. La situation en Grande Bretagne est peut-être exacerbée par le Brexit et la situation insulaire mais elle est l'avant-poste de ce qui attend une bonne part du monde industrialisé, à moins de relancer le charbon avec toutes les conséquences sur le dérèglement climatique et la santé des personnes que nous connaissons.

Four months into US oil blockade, Cubans see island drained as state electric company fights to provide even a few hours of power a day Ruaridh Nicoll in Havana - The doctor called from the darkness, a shadowy figure sitting on the stoop of his apartment building. “I want to tell you we’ve been four days without light,” he said. “And without electricity, water is also a problem. And there are mosquitoes everywhere.”

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...

Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration

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

The Global Justice Project attempts to set out a new vision for global progress in the 21st century: grounding human development and equality in planetary habitability. It explores the conditions under which the world could move toward this horizon and traces an economically and ecologically consistent transition path from 2026 to 2100.

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].

While the term “Anthropocene” is well established across scientific disciplines and social spheres, interpretations are diverse. Taking account of the 2024 rejection by a geological commission to accept the Anthropocene as a geological epoch and the related scientific debate, here we offer a future-oriented perspective from the viewpoint of Earth system science. We describe different pathways in the Anthropocene up to the year 3,000, systematically characterizing them according to impacts and causes. We discuss the enormous global consequences of anthropogenic pressures on the Earth system and quantify the corresponding long-term commitment to change. Regarding the causes, we conservatively explore best-case and middle-of-the road emission scenarios, in combination with climate sensitivities drawn from within the IPCC likely range. We also discuss implications for Earth system resilience that could result in what we call worst case scenarios for Anthropocene outcomes. We conclude that, beyond the slow pace of

The Trump administration is dismantling a $368 million deep-ocean observation system that was put in place a decade ago to monitor coastal environments, marine ecosystems and powerful currents that affect the global climate.

The British-Canadian computer scientist often touted as a “godfather” of artificial intelligence has shortened the odds of AI wiping out humanity over the next three decades, warning the pace of change in the technology is “much faster” than expected. Prof Geoffrey Hinton, who this year was awarded the Nobel prize in physics for his work in AI, said there was a “10% to 20%” chance that AI would lead to human extinction within the next three decades.

- 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.

Our roadmap has been shaped by experts across the world, from UN agencies to grassroots movements. We call on political leaders at all levels to use it
