I know it’s almost impossible to turn your eyes away from the Trump show, but that’s the point. His antics, ever-grosser and more preposterous, are designed to keep him in our minds, to crowd out other issues. His insatiable craving for attention is a global-threat multiplier. You can’t help wondering whether there’s anything he wouldn’t do to dominate the headlines.

States and financial bodies using modelling that ignores shocks from extreme weather and climate tipping points

Global biodiversity loss, ecosystem collapse and national security - A national security assessment

Ecosystem destruction will increase food shortages, disorder and mass migration, with effects already being felt

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.

Perception, pattern-seeking, and the role of neurodivergence in a failing civilisation

Mon essai précédent explorait pourquoi certaines personnes perçoivent l’effondrement plus tôt que d’autres. Celui-ci pose une autre question : si l’effondrement ne peut pas être évité, à quoi sert réellement une prise de conscience précoce ?

For some, the crisis in Venezuela is all about the endemic corruption of Nicolás Maduro, continuing the broken legacy of Chavez’s ideological experiment in socialism under the mounting insidious influence of Putin. For others, it’s all about the ongoing counter-democratic meddling of the United States, which has for years wanted to bring Venezuela — with its huge oil reserves — back into the orbit of American power, and is now interfering again to undermine a democratically elected leader in Latin America.

Hidden in every tenth of a degree of extra warmth are hair-trigger switches built into Earth systems that are critical for all life.

Glacial earthquakes are a special type of earthquake generated in cold, icy regions. First discovered in the northern hemisphere more than 20 years ago, these quakes occur when huge chunks of ice fall from glaciers into the sea. Until now, only a very few have been found in the Antarctic. In a new study soon to be published in Geophysical Research Letters, I present evidence for hundreds of these quakes in Antarctica between 2010 and 2023, mostly at the ocean end of the Thwaites Glacier – the so-called Doomsday Glacier that could send sea levels rising rapidly if it were to collapse.
