A recent paper suggested damaging climate tipping points could be closer than first thought.

Le Hezbollah et son allié Amal ont annoncé mercredi soir huit morts dans leurs rangs, parmi lesquels des secouristes, dans des frappes israéliennes dans le sud du Liban portant à 16 le nombre de victimes d'une journée d'échanges de tirs transfrontaliers.

Après les attaques répétées de bateaux dans la mer Rouge par les rebelles houthis, les compagnies maritimes évitent l'un des principaux corridors du commerce mondial, ce qui devrait perturber les échanges, avec des retards et des surcoûts. Que s'est-il passé?Ces dernières semaines, des rebelles houthis du Yémen, proches de l'Iran, ont multiplié les attaques près du détroit stratégique de Bab al-Mandeb, qui sépare la péninsule arabique de l'Afrique.

Les Etats-Unis et le Japon ont signé mardi un accord visant à renforcer "les chaînes d'approvisionnement pour les minéraux critiques et les batteries pour véhicules électriques" et renforcer les échanges entre les deux pays concernant ces produits essentiels à la transition énergétique et jusqu'ici dominés par la Chine.

Can we talk about it now? I mean the subject most of the media and most of the political class has been avoiding for so long. You know, the only subject that ultimately counts – the survival of life on Earth. Everyone knows, however carefully they avoid the topic, that, beside it, all the topics filling the front pages and obsessing the pundits are dust. Even the Times editors still publishing columns denying climate science know it. Even the candidates for the Tory leadership, ignoring or downplaying the issue, know it. Never has a silence been so loud or so resonant.

Persistent heat extremes can have severe impacts on ecosystems and societies, including excess mortality, wildfires, and harvest failures. Here we identify Europe as a heatwave hotspot, exhibiting upward trends that are three-to-four times faster compared to the rest of the northern midlatitudes over the past 42 years. This accelerated trend is linked to atmospheric dynamical changes via an increase in the frequency and persistence of double jet stream states over Eurasia. We find that double jet occurrences are particularly important for western European heatwaves, explaining up to 35% of temperature variability. The upward trend in the persistence of double jet events explains almost all of the accelerated heatwave trend in western Europe, and about 30% of it over the extended European region. Those findings provide evidence that in addition to thermodynamical drivers, atmospheric dynamical changes have contributed to the increased rate of European heatwaves, with implications for risk management and potent

Food supply expert paints grim global picture hunger 05.23.2022 By Arvin Donley NEW YORK, NEW YORK, US — Global wheat inventories currently stand at about 10 weeks of global consumption, a food supply expert said during a special meeting of the United Nations Security Council on May 19. Sara Menker, chief executive officer of Gro Intelligence, an organization that gathers and analyzes global food and agricultural data, said she disputes official government agency estimates that put global wheat inventories at 33% of annual consumption, countering inventories are closer to 20%. “It is important to note that the lowest grain inventory levels the world has ever seen are now occurring while access to fertilizers is highly constrained, and drought in wheat growing regions around the world is the most extreme it’s been in over 20 years,” Menker said. “Similar inventory concerns also apply to corn and other grains. Government estimates are not adding up.” Menker told the security council that while much of the blame

Momentum to phase out unabated coal use is growing globally. This transition is critical to meeting the Paris climate goals but can potentially lead to large amounts of stranded assets, especially in regions with newer and growing coal fleets. Here we combine plant-level data with a global integrated assessment model to quantify changes in global stranded asset risks from coal-fired power plants across regions and over time. With new plant proposals, cancellations, and retirements over the past five years, global net committed emissions in 2030 from existing and planned coal plants declined by 3.3 GtCO2 (25%). While these emissions are now roughly in line with initial Nationally Determined Contributions (NDCs) to the Paris Agreement, they remain far off track from longer-term climate goals. Progress made in 2021 towards no new coal can potentially avoid a 24% (503 GW) increase in capacity and a 55% ($520 billion) increase in stranded assets under 1.5 °C. Stranded asset risks fall disproportionately on emergin

The Gulf Stream has weakened substantially in the past decades, as revealed by the latest data and new studies. Weather in the United States and Europe depends strongly on this ocean current, so it’s important we understand the ongoing changes and what they mean for our weather now and in the near future.
