Des modèles économiques défaillants pourraient faire s’effondrer l’économie mondiale à cause de la crise climatique, préviennent des experts. Les États et les institutions financières utilisent des modèles qui ignorent les chocs liés aux événements météorologiques extrêmes et aux points de bascule climatiques.
Doyne Farmer says a super-simulator of the global economy would accelerate the transition to a green, clean world
Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware
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.
La production alimentaire et les combustibles fossiles causent 5 milliards de dollars de dégâts environnementaux par heure Un rapport du PNUE affirme que mettre fin à ces dommages est essentiel à la transformation mondiale nécessaire « avant que l’effondrement ne devienne inévitable ».

The world has entered an era of “global water bankruptcy” that is harming billions of people, a UN report has declared. The overuse and pollution of water must be tackled urgently, the report’s lead author said, because no one knew when the whole system could collapse, with implications for peace and social cohesion. All life depends on water but the report found many societies had long been using water faster than it could be replenished annually in rivers and soils, as well as over-exploiting or destroying long-term stores of water in aquifers and wetlands.
Scientists expect 41% of the projected global population to face the extremes, with ‘no part of the world’ immune

US demand to own Greenland leaves little scope for compromise, and forcing the issue would entail end of Nato Greenland, with a population of fewer than 57,000, might not seem to be the territory on which the future of the relationship between Europe and the US, the viability of Nato as the world’s most successful defence alliance, or even the fractured relations between the UK and Europe would be determined. But battlefields are sometimes the product of chance, rather than choice. It now feels as if Donald Trump’s threat to impose 10% tariffs on eight fellow Nato states for sending troops last week to support Greenland’s sovereignty may be one of those clarifying moments in which Europe had no option. Successive European leaders condemned Trump’s blackmail and intimidation on Sunday and they sounded as if they meant it.
Progress of artificial general intelligence could stall, which may lead to a financial crash, says Yoshua Bengio, one of the ‘godfathers’ of modern AI

Mais les mesures convenues constituent des pas en avant, plutôt que les bonds en avant nécessaires.

US president’s son-in-law was instrumental in getting deal – which could bring him huge windfall if plan to redevelop Gaza ever comes to fruition […] For a man with no formal role in the White House, Jared Kushner last week literally took centre-stage as Donald Trump’s emissary to the Middle East. As the administration took a victory lap for hammering out a Gaza ceasefire last week, Kushner, Trump’s son-in-law, stood in Tel Aviv’s ‘hostages square’, addressing a feverish crowd that had booed the mention of Israel’s prime minister, Benjamin Netanyahu, and later broke into chants of: “Thank You Trump!”

Une commission d’enquête des Nations unies a désormais confirmé ce que les organisations israéliennes, palestiniennes et internationales de défense des droits humains, ainsi que de nombreux spécialistes du génocide, affirmaient déjà : la guerre menée par Israël à Gaza équivaut à un génocide. La commission estime que les massacres, les attaques contre les infrastructures vitales, la famine, les déplacements de population et le refus de soins médicaux répondent à la définition juridique du crime le plus grave de l’histoire. Elle conclut que l’intention génocidaire est « la seule conclusion raisonnable » à tirer des déclarations des dirigeants israéliens et du comportement de leurs forces à Gaza.

‘We are perilously close to the point of no return’: climate scientist on Amazon rainforest’s future
- Jonathan Watts,Carlos Nobre,
For more than three decades, Brazilian climate scientist Carlos Nobre has warned that deforestation of the Amazon could push this globally important ecosystem past the point of no return. Working first at Brazil’s National Institute for Space Research and more recently at the University of São Paulo, he is a global authority on tropical forests and how they could be restored.
