« Ce que nous mangeons et les méthodes de production alimentaire ont une incidence sur notre santé ainsi que sur l’environnement. Les aliments doivent être cultivés et transformés, transportés, distribués, préparés, consommés puis, parfois, éliminés. Chacune de ces étapes génère des gaz à effet de serre qui retiennent la chaleur du soleil et contribuent au changement climatique. Plus d’un tiers des émissions de gaz à effet de serre imputables aux activités humaines sont liées à l’alimentation. »

As the world’s largest gathering of Earth and space scientists swarmed a Washington venue last week, the packed halls have been permeated by an air of anxiety and even dread over a new Donald Trump presidency that might worsen what has been a bruising few years for science.
Warning after intensification of storm aided by unusually hot ocean waters in much of Beryl’s path. Hurricane Beryl, which slammed into Texas on Monday after wreaking havoc in the Caribbean, was supercharged by “absolutely crazy” ocean temperatures that are likely to fuel further violent storms in the coming months, scientists have warned.
World’s fossil-fuel producers on track to nearly quadruple output from newly approved projects by decade’s end, report finds
James Hansen says limit will be passed ‘for all practical purposes’ by May though other experts predict that will happen in 2030s

Extreme weather is ‘smacking us in the face’ with worse to come, but a ‘tiny window’ of hope remains, say leading climate scientists
Selon James Hansen – le scientifique des Etats-Unis qui a alerté le monde sur l’effet de serre dans les années 1980 – le monde est en train de basculer vers un climat surchauffé jamais vu l’existence de l’homme, parce que «nous sommes de sacrés imbéciles» pour ne pas avoir réagi aux avertissements concernant la crise climatique.
le scientifique qui a tiré la sonnette d’alarme sur le climat dans les années 80 annonce le pire pour l’avenir. James Hansen, qui a témoigné devant le Congrès sur le réchauffement de la planète en 1988, affirme que le monde s’approche d’une « nouvelle limite climatique ».
James Hansen, who testified to Congress on global heating in 1988, says world is approaching a ‘new climate frontier’
Several US states say news that Exxon scientists predicted global heating accurately strengthens their lawsuits against company
The oil giant Exxon privately “predicted global warming correctly and skilfully” only to then spend decades publicly rubbishing such science in order to protect its core business, new research has found.

Planned drilling projects across US land and waters will release 140bn metric tons of planet-heating gases if fully realised, an analysis shared with the Guardian has found. The study, to be published in the Energy Policy journal this month, found emissions from these oil and gas “carbon bomb” projects were four times larger than all of the planet-heating gases expelled globally each year, placing the world on track for disastrous climate change.

The enormous, unprecedented pain and turmoil caused by the climate crisis is often discussed alongside what can seem like surprisingly small temperature increases – 1.5C or 2C hotter than it was in the era just before the car replaced the horse and cart.
Drawing people into cities could cut emissions and combat housing crises. But even progressives are hard to convince
Greenland’s vast ice sheet is undergoing a surge in melting, with the amount of ice vanishing in a single day this week enough to cover the whole of Florida in two inches of water, researchers have found.
The lifestyles of around three average Americans will create enough planet-heating emissions to kill one person, and the emissions from a single coal-fired power plant are likely to result in more than 900 deaths, according to the first analysis to calculate the mortal cost of carbon emissions.
The shocking collapse of a 12-storey building in the Miami area last week has raised questions as to the role played by the climate crisis, and whether the severe vulnerability of south Florida to the rising seas may lead to the destabilization of further buildings in the future.
Officials prepare to elevate streets despite financial shortfalls, amid recognition that not every home can be save. Long famed for its spectacular fishing, sprawling coral reefs and literary residents such as Ernest Hemingway, the Florida Keys is now acknowledging a previously unthinkable reality: it faces being overwhelmed by the rising seas and not every home can be saved.

Les scientifiques ont révélé l’année dernière que la glace du Groenland disparaissait sept fois plus vite qu’elle ne l’était dans les années 1990, ce qui fait grimper les estimations précédentes concernant l’élévation du niveau de la mer et expose 400 millions de personnes au risque d’inondation d’ici la fin du siècle.
