Intempéries

Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today. But what if there was another, greater, human-made threat that could snuff out not only human civilisation, but practically the entire biosphere, in the blink of an eye?

Exclusive: Climate.gov, which supports public education on climate science, will soon no longer publish new contentA major US government website supporting public education on climate science looks likely to be shuttered after almost all of its staff were fired, the Guardian has learned.

Fifteen years ago, smack in the middle of Barack Obama's first term, amid the rapid rise of social media and a slow recovery from the Great Recession, a professor at the University of Connecticut issued a stark warning: the United States was heading into a decade of growing political instability.

Anthropic’s latest artificial intelligence model, Claude Opus 4, tried to blackmail engineers in internal tests by threatening to expose personal details if it were shut down, according to a newly released safety report that evaluated the model’s behavior under extreme simulated conditions.

J’ai l’habitude de voir les écologistes et les futurologues parler des limites de la croissance (« The Limits to Growth »). Je suis moins habitué à voir des spécialistes de l’investissement mentionner des recherches liées aux limites de la croissance. C’est pourtant ce qu’a fait récemment Joachim Klement dans sa lettre d’information quotidienne. Bien entendu, quiconque écrit sur les limites de la croissance doit d’abord procéder à toutes les vérifications d’usage. En effet, la combinaison des mots « limites » et « croissance » dans le titre a suscité un grand nombre de réactions critiques, allant de la déformation pure et simple de l’ouvrage à l’incompréhension du modèle de dynamique des systèmes qui le sous-tend.

I’m used to environmentalists and futurists writing about The Limits to Growth. I’m less used to seeing investment writers mention research that’s linked to The Limits of Growth. But that’s what Joachim Klement did in his daily newsletter recently. Of course, anyone who writes about Limits of Growth has to do all the usual disclaimers first. This is because the combination of the words “limits” and “growth” in the title produced a lot of critical responses, on a range from straight-up hatchet jobs which misrepresented the book, to people who didn’t appear to understand the systems dynamics model that sat behind it.

Before you read this, a word of caution. You may want to prepare yourself a stiff drink and sit down before you read the following. I think most people who read this will at some point in their life heard about the Club of Rome’s Limit to Growth publication from the 1970s. Back then, the Club of Rome asked the MIT to produce a series of forecasts for the world’s industrial and services output, food production, and pollution levels to the year 2100. Almost from the get-go, these forecasts were derided as scaremongering and flat out wrong. But were they really?

"Elon Musk est en train de détruire notre démocratie et d'utiliser la fortune qu'il a bâtie chez Tesla pour y parvenir", peut-on lire sur le site de TeslaTakedown, qui insiste sur le caractère pacifique des protestations. Le mouvement appelle à manifester et à boycotter Tesla, en vendant les actions de l'entreprise. Des rassemblements sont prévus aux États-Unis, au Canada, en Irlande, en Norvège, en Finlande, au Royaume-Uni, au Danemark, en Allemagne, aux Pays-bas et en Suisse. En France, des manifestations se tiendront à Beauvais et Paris. Aucune action n'est programmée en Belgique.

Donald Trump has ordered that swathes of America’s forests be felled for timber, evading rules to protect endangered species while doing so and raising the prospect of chainsaws razing some of the most ecologically important trees in the US. The president, in an executive order, has demanded an expansion in tree cutting across 280m acres (113m hectares) of national forests and other public lands, claiming that “heavy-handed federal policies” have made America reliant on foreign imports of timber.

💡 Is our obsession with economic growth leading us to collapse? Economist and research Gaya Herrington joins us to discuss why GDP is a flawed metric, how degrowth can lead to a thriving well-being economy, and why businesses must prioritize resilience over efficiency. Tune in for a critical conversation on reshaping our economic future.

Britain’s crackdown on climate protest is setting “a dangerous precedent” around the world and undermining democratic rights, the UK director of Human Rights Watch has said. In the UK “laws criminalising protests undermine democratic rights”, the NGO says in its latest annual world report, published on Thursday, adding that in the past year “the UK continued to crack down on and criminalise climate protests”.

British police arrest environmental protesters at nearly three times the global average rate, research has found, revealing the country as a world leader in the legal crackdown on climate activism.

Avant de lancer cette chaîne. Nous avions créer un pilote lorsque j'étais encore sur ‪@TarmacRTBF‬ la plate-forme média de la ‪@rtbf‬ qui avait pour vocation d'introduire les limites planétaires à des personnes qui n'y connaissaient rien. "1,5°C" était le titre que nous avions trouvé en symbole avec les accords de paris de la COP 21. Cette vidéo j'ose espérer captivante revient sur le constat global de notre époque : comment notre planète, nos écosystèmes et nos sociétés sont à la croisée des chemins face au changement climatique. Avec des invités comme ‪@jean-marcjancovici2537‬ Pablo Servigne, ‪@RokhayaDialloFR‬ ou encore le climatologue François Massonnet de ‪@universitedelouvain‬ nous dressons un état des lieux sans concessions mais aussi porteur d'espoir.

Added complexity allows an economy to grow, even as resource limits are reached. But at some point, the complexity itself becomes a problem.

Moscou accuse l’Ukraine d’avoir lancé le mercredi 20 novembre sur une cible militaire russe six missiles de longue portée fournis par le Royaume Uni.

En 1972 sont publiés les résultats d'un travail de modélisation en dynamique des systèmes réalisé par un groupe de chercheurs du MIT, et commandité par le Club de Rome, intitulé les limites à la croissance. Ce travail passera à la postérité comme "le rapport Meadows", du nom de deux de ces co-auteurs : Donella et Dennis Meadows.

‘Catastrophic’ global decline due to dams, mining, diverting water and pollution threatens humans and ecosystems, study warns

Record-breaking temperatures were recorded across the globe in 2023. Without climate action, adverse climate-related health impacts are expected to worsen worldwide, affecting billions of people. Temperatures in Europe are warming at twice the rate of the global average, threatening the health of populations across the continent and leading to unnecessary loss of life. The Lancet Countdown in Europe was established in 2021, to assess the health profile of climate change aiming to stimulate European social and political will to implement rapid health-responsive climate mitigation and adaptation actions. In 2022, the collaboration published its indicator report, tracking progress on health and climate change via 33 indicators and across five domains.
