A la hausse constante des prix alimentaires s'ajoutent les effets de plus en plus dramatiques du changement climatique et un monde de plus en plus instable. Serons-nous réellement capables de nourrir une population qui devrait bientôt atteindre 10 milliards. Le professeur Tim Benton, l’un des plus grands experts mondiaux des systèmes alimentaires, estime que notre modèle économique de croissance infinie sur une planète aux ressources finies est voué à s’effondrer. Mais quand cela se produira-t-il ? Qu’est-ce que cela signifie concrètement ? Et enfin, entrons-nous réellement dans une ère de famine ?

Tim Benton, expert reconnu en sécurité alimentaire mondiale, afin de comprendre les causes de l'effondrement de nos systèmes alimentaires et les conditions nécessaires à la construction d'un système véritablement régénérateur. – Pourquoi le système alimentaire actuel est fondamentalement insoutenable – Que signifie concrètement le concept de « limites planétaires » – Le mythe de la croissance verte – Comment nos régimes alimentaires et nos systèmes agricoles doivent évoluer – Les 3 mécanismes qui nous empêchent d'avancer

Climate models simulate a wide range of 21st century warming for a given forcing scenario. Constraining this uncertainty is a central challenge in climate science because of its implications for climate policy and adaptation. The Transient Climate Response (TCR) is a key idealized metric used to quantify future warming in response to an exponentially increasing CO2 concentration. Climate models span a range of 1.3–3 K for TCR. In attempts to constrain this range, emergent constraints on TCR based on historical temperature trends consistently pointed towards TCR values at the lower end of the range of models. However, recent evidence from trends in the short-wave and long-wave components of Earth's energy imbalance (EEI) at the top-of-atmosphere suggests that models with higher TCR lie closer to the observed EEI trends. Here, we reconcile this discrepancy and provide a revised range for TCR of 1.9–2.6 K. Using a statistical variability-filtering approach, we show that previous temperature-based constraints we

Alarming warnings from industry insiders increase pressure for curbs on artificial superintelligence

What sounds like the overwrought penultimate episode in a sci-fi series about AI doom is now our reality

Les systèmes d'intelligence artificielle sont entrainés sur les comportements humains qu'ils lisent et regardent/écoutent. Dès lors, le mensonge est une partie intégrante de leurs stratégies. Leur capacité (à mentir et à masquer leurs mensonges) risque de nous dépasser assez rapidement.

A new study finds two persistent mental shortcuts—not ignorance—are why people keep overrating recycling and underrating flying less.

Exclusive: Federal government court filings claim internal company documents included warnings about products being toxic

Global biodiversity loss, ecosystem collapse and national security: a national security assessment

This summer’s extreme weather and wars in Iran and Ukraine have made our need for food stockpiles more pressing than ever

Europe is full of buried explosives left over from 20th century wars, and wildfires are now reaching them more regularly.

Exclusive: As wildfires rage, Frank Elderson says more work needed to assess risk from collapse of ecosystem services

Exclusive: Global investigation reveals 235 lawsuits have been brought against governments in five countries since 2010

Members of parliament have demanded full publication of an explosive report by the UK’s spy leaders that found the collapse of ecosystems overseas would have catastrophic consequences for the UK’s national security, warning that the UK has “no future” if the findings are not urgently acted on.

The fluoropolymer industry is at it again. The industry’s most notable products are non-stick industrial coatings such as Teflon, made using forever chemicals (per- and polyfluoroalkyl substances: PFAS). But as the European Chemicals Agency (ECHA) starts to wind up its second public consultation on the proposed EU PFAS ban, the fluoropolymer industry is once again mobilising its customers to criticise alternatives to their products.

For most of the modern era, capitalism justified itself through growth. Industrial societies converted vast amounts of fossil energy into production, wealth, and rising living standards. Roads, bridges, power grids, schools, and public institutions expanded alongside the economy. Inequality and exploitation remained deeply embedded in the system, but they were partly obscured by a broader story of material progress.

Cet article rapporte la difficulté du secteur manufacturier en Grande Bretagne à faire face à l’augmentation du cout de l'énergie. Dans l'ombre de cet article apparait ce qui sera la réalité à un moment donné, sans pétrole bon marché, l'industrie manufacturière ne peut pas fonctionner dans les conditions actuelles. Le contrat social sera rompu et il faudra réinventer une manière de vivre ensemble. La situation en Grande Bretagne est peut-être exacerbée par le Brexit et la situation insulaire mais elle est l'avant-poste de ce qui attend une bonne part du monde industrialisé, à moins de relancer le charbon avec toutes les conséquences sur le dérèglement climatique et la santé des personnes que nous connaissons.

Projections of near-term climate change are a potential research tool. However, for that tool to be most useful, the physical basis for a prediction must be made clear. The basis for our projection of record 2026 global temperature is high climate sensitivity, with its implication that aerosol cooling was still increasing during the period 1970-2005. One consequence, global sea surface warming, already has important effects. Causes of climate change must be understood for policy purposes.
