The long read: Churning quantities of carbon dioxide into the atmosphere at the rate we are going could lead the planet to another Great Dying

« La malédiction de Goliath : brève histoire et avenir de l’effondrement sociétal. » Retrouvez une conférence de Luke Kemp du 8 Septembre 2022 à Princeton; cette conférence correspond à la première partie du livre "La malédiction de Goliath" qui vient de sortir chez Penguin Books (en anglais)

À Grand-Laviers (Somme), le parcours de golf a laissé place à une riche biodiversité. Le nouveau propriétaire du terrain, un hôtelier, veut montrer que les projets d’espaces naturels protégés peuvent aussi être portés par des acteurs privés. Un parcours semé d’embûches, qu’il a raconté à Vert.

Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say

For decades, the surface of the polar Southern Ocean (south of 50°S) has been freshening—an expected response to a warming climate. This freshening enhanced upper-ocean stratification, reducing the upward transport of subsurface heat and possibly contributing to sea ice expansion. It also limited the formation of open-ocean polynyas. Using satellite observations, we reveal a marked increase in surface salinity across the circumpolar Southern Ocean since 2015. This shift has weakened upper-ocean stratification, coinciding with a dramatic decline in Antarctic sea ice coverage. Additionally, rising salinity facilitated the reemergence of the Maud Rise polynya in the Weddell Sea, a phenomenon last observed in the mid-1970s.

Real world measurements of how much extra heat the Earth is trapping are well beyond most climate models. That’s a real problem.

Repeatedly mass infecting kids with COVID is not a public health strategy. It's a fast pass to declining population health

Guardian investigation finds almost 7,000 proven cases of cheating – and experts says these are tip of the iceberg

Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.

It’s not just Florida and California — from poisoned water supplies to infrastructure issues to polar vortices, Holly Baxter speaks to experts about why the entire U.S. is being threatened by climate change, and why you can’t just move to Vermont to escape it

In 2022, one of Peter Thiel's favorite thinkers envisioned a second Trump Administration in which the federal government would be run by a “CEO”

Le mouvement Make America Great Again (MAGA) et ses liens avec la Silicon Valley ont fait naître le « techno-fascisme ». Cette expression peut paraître rigolote ou exagérée, mais elle n’a jamais été aussi près de la réalité. L’arrivée au pouvoir de Donald Trump avec un mandat autoritaire et ultra-conservateur aligné sur le Projet 2025, le virage à droite des milliardaires et dirigeants des GAFAM qui célèbrent l’arrivée du nouveau président, le décret annulant la réglementation de l’intelligence artificielle (IA), le financement du projet Stargate à 500 milliards de dollars, tout cela participe d’un même mouvement.

Revealed: US climate denial group working with European far-right parties Representatives of Heartland Institute linking up with MEPs to campaign against environmental policies Helena Horton, Sam Bright and Clare Carlile Wed 22 Jan 2025 13.01 CET Last modified on Wed 22 Jan 2025 14.27 CET Climate science deniers from a US-based thinktank have been working with rightwing politicians in Europe to campaign against environmental policies, the Guardian can reveal. MEPs have been accused of “rolling out the red carpet for climate deniers” to give them a platform in the European parliament, amid warnings of a “revival of grotesque climate denialism”.

Les agriculteurs jouent un rôle crucial dans la lutte contre le réchauffement climatique. En tant que principaux acteurs de l'agriculture, ils sont à la fois contributeurs aux émissions de gaz à effet de serre et victimes des impacts climatiques tels que la sécheresse, les incendies et la diminution des rendements…

As authorities declared 2024 the hottest on record, a key private sector climate alliance, the Glasgow Financial Alliance for Net Zero (GFANZ) abandoned a requirement that members be aligned to the Paris agreement. That was followed by a network of net zero asset managers suspending work, and deleting from its website its statement of commitments that members must adopt, after BlackRock, the biggest of them all, quit its ranks.
