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.

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

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

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.

On ignore les raisons qui font que les systèmes de contrôle à distance des matériaux nucléaires ont cessé d’émettre mardi soir. Les échanges avec la centrale, sous contrôle russe, ne peuvent se faire que par courrier électronique.

Fatigué après avoir organisé l'évacuation de Kiev d'une partie de son équipe, Mike Chobanian, patron de la plateforme d'échanges de cryptomonnaies Kuna, observe sans broncher les conséquences économiques de l'offensive russe sur son entreprise, l'une des plus importantes d'un secteur florissant en Ukraine.

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

Tree diversity is fundamental for forest ecosystem stability and services. However, because of limited available data, estimates of tree diversity at large geographic domains still rely heavily on published lists of species descriptions that are geographically uneven in coverage. These limitations have precluded efforts to generate a global perspective. Here, based on a ground-sourced global database, we estimate the number of tree species at biome, continental, and global scales. We estimated a global tree richness (≈73,300) that is ≈14% higher than numbers known today, with most undiscovered species being rare, continentally endemic, and tropical or subtropical. These results highlight the vulnerability of global tree species diversity to anthropogenic changes.

Berkeley Earth, a California-based non-profit research organization, has been preparing independent analyses of global mean temperature changes since 2013. The following is our report on global mean temperature during 2021.

Selon d’anciens échanges d’e-mails révélés par la VRT, il est clair que le politique a freiné en 2017 la communication sur la pollution aux PFOS (des composés perfluorés toxiques) à Zwijndrecht. Les mails semblent pointer la ministre flamande de l’Environnement de l’époque, Joke Schauvliege (CD&V), et celui qui était compétent pour la Mobilité et les travaux de la liaison Oosterweel, le N-VA Ben Weyts.

L’Afghanistan s’enfonce chaque jour un peu plus dans la crise. Depuis la prise du pouvoir par les talibans, la plupart des bureaux de service public, les banques et le principal marché des changes ont fermé, plongeant encore un peu plus la population dans une situation d’insécurité alimentaire.

The Gulf Stream has weakened substantially in the past decades, as new data and studies show. 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 will mean for our weather in the future.

Global greenhouse gas emissions must peak in the next four years, coal and gas-fired power plants must close in the next decade and lifestyle and behavioural changes will be needed to avoid climate breakdown, according to the leaked draft of a report from the world’s leading authority on climate science.

As the world battles historic droughts, landscape-altering wildfires and deadly floods, a landmark report from global scientists says the window is rapidly closing to cut our reliance on fossil fuels and avoid catastrophic changes that would transform life as we know it. The state-of-the-science report from the United Nations' Intergovernmental Panel on Climate Change says the world has rapidly warmed 1.1 degrees Celsius higher than pre-industrial levels, and is now careening toward 1.5 degrees — a critical threshold that world leaders agreed warming should remain below to avoid worsening impacts.

The Atlantic Ocean's current system, an engine of the Northern Hemsiphere's climate, could be weakening to such an extent that it could soon bring big changes to the world's weather, a scientific study said on Thursday.

Scientists know that global warming is changing clouds, but they haven’t been sure whether those changes would heat or cool the planet overall. It’s an important question, because clouds have been the main source of uncertainty in projecting just how sensitive the climate is to increasing greenhouse gas concentrations, and because clouds have a huge effect on the climate system.

New research suggests social transformations that prompt “degrowth” could cut humanity’s climate footprint in time to meet the Paris climate agreement target.

Si le prix du carbone s’appliquait à l’ensemble des pays, sans frontières, les règles du jeu seraient identiques pour tous. À l’inverse, un prix du carbone appliqué à une seule zone peut impacter les échanges commerciaux. Il risquerait d’inciter les entreprises à délocaliser les émissions vers les régions sans tarification carbone plutôt qu’à les réduire. C’est le risque dit de « fuites de carbone », qui soulève la question du lien entre la politique climatique de l’Union européenne (UE) et sa politique commerciale.

Une animation produite par des chercheurs de la NASA permet de visualiser le détail des échanges de CO2 entre l’atmosphère et l’océan. En particulier, la résolution journalière du produit permet d’accéder à l’importante variabilité spatiale et temporelle des flux. Ces données servent à comprendre de façon toujours plus fine le fonctionnement du cycle du carbone.

L’arrêt de l’économie à cause de la pandémie de Covid-19, du confinement et du ralentissement des échanges internationaux a de nouveau soulevé la question de la place du commerce dans nos vies. Qui dit commerce dit accords. La pertinence de ces politiques commerciales est notamment remise en cause en raison de leurs impacts sur l’environnement, l’économie et la démocratie

The growing threat of abrupt and irreversible climate changes must compel political and economic action on emissions.

Selon le professeur britannique Andrew Ellis, Internet pourrait s'effondrer en 2023 à la suite d'une saturation des réseaux provoquée par l'explosion des échanges de données. Contactés par nos confrères de la rédaction d'Industrie & Technologies, des spécialistes de la question nuancent ce scenario alarmiste.

The centerpiece of the early anthropogenic hypothesis is the claim that humans took control of greenhouse-gas trends thousands of years ago because of emissions from early agriculture ( [32] and [33]). A common reaction to this claim is that too few people lived thousands of years ago to have had a major effect on either land use or greenhouse-gas concentrations.
