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.

As climate and geopolitics shocks bite, countries are rebuilding food buffers. The UK clings to neoliberal ideas while households pay the price

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.

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.

Bronwen Maddox says Trump’s rejection of international law leaves UK and Europe facing huge dilemma

“Combustion is the problem – when you’re continuing to burn something, that’s not solving the problem,” says Prof Mark Jacobson. The Stanford University academic has a compelling pitch: the world can rapidly get 100% of its energy from renewable sources with, as the title of his new book says, “no miracles needed”. Wind, water and solar can provide plentiful and cheap power, he argues, ending the carbon emissions driving the climate crisis, slashing deadly air pollution and ensuring energy security. Carbon capture and storage, biofuels, new nuclear and other technologies are expensive wastes of time, he argues.

Progress of artificial general intelligence could stall, which may lead to a financial crash, says Yoshua Bengio, one of the ‘godfathers’ of modern AI

We are living in a time of polycrisis. If you feel trapped – you’re not alone. I hadn’t fully grasped how the idea of a better future sustained me – now I, like many others, find it difficult to be productive
