Le collapswashing, succédant au greenwashing, désigne non seulement la dissimulation des destructions environnementales mais dénonce également ceux qui font croire qu’ils préviennent les risques de déclin ou d’effondrement, alors qu’ils ne font que dissimuler ce qui décline ou s’effondre.

Last month was the hottest January on record, blitzing the previous high and stunning climate scientists who expected cooler La Niña conditions to finally start quelling a long-running heat streak. The Copernicus Climate Change Service said January was 1.75C hotter than pre-industrial times, extending a persistent run of historic highs over 2023 and 2024, as human-caused greenhouse gas emissions heat the planet.

As of February 22, over twenty Stand Up for Science protests are scheduled for March 7 throughout the United States.

An international group of scientists, led by King's College London, has revealed how continued global warming will lead to more parts of the planet becoming too hot for the human body over the coming decades. the amount of landmass on our planet that would be too hot for even healthy young humans (18 to 60-year-olds) to keep a safe core body temperature will approximately triple (to 6%)—an area almost the size of the US—if global warming reaches 2°C above the preindustrial average.
An engaging discussion on groundbreaking research that reveals the unexpected drivers behind the recent unprecedented rise in global temperatures. Moderated by SDSN President Professor Jeffrey Sachs, this virtual event explored Dr. James Hansen and colleagues' findings in the latest publication, “Global Warming Has Accelerated,” their implications for climate sensitivity, and the urgent need for alternative approaches to mitigate the looming "point of no return."

While some progress has been made in limiting greenhouse gas emissions, we are still on the path for high levels of global warming
Clouds play an important role in how much the Earth warms when greenhouse gases like carbon dioxide increase. However, scientists have struggled to determine whether low-level clouds in the tropics slow down or speed up global warming, creating uncertainty in climate predictions. A new study published in Nature adds to the growing evidence that cloud feedback is very likely to amplify warming in the climate system, rather than reduce it.

The climate and ecological crisis poses an unprecedented challenge, with scientists playing a critical role in how society understands and responds. This study examined how 27 environmentally concerned scientists from 11 countries construct the future in the context of climate change, applying a critical discursive psychology analysis. The degree to which the future is constructed as predetermined or transformable impacts both the urgency and scope of proposed actions. ...

À la veille des élections, des scientifiques mènent des actions dans la capitale pour alerter sur les risques climatiques. Les rapports alarmants sur le climat se multiplient, mais le monde politique n’en tient pas suffisamment compte aux yeux des scientifiques. Pour mieux se faire entendre, des chercheurs et académiques belges et internationaux ont donc décidé, en cette veille d’élections, d’opter pour la désobéissance civile.
Ce matin une vingtaine de scientifiques ont bloqué les entrées de la Commission européenne afin de réclamer la décroissance vue comme “la seule option pour sortir de l’impasse sociale et environnementale”

The Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world. The Amazon, which holds more than 10 percent of the world's biodiversity, helps stabilize the global climate by storing the equivalent of around two decades of emissions of planet-warming carbon dioxide.

Humanity faces ‘devastating domino effects’ including mass displacement and financial ruin as planet warms

Referring to the Paris Agreement’s target of keeping Earth from warming no more than 1.5 degrees Celsius since the Industrial Revolution, the number has become a rallying cry for climate advocates and scientists, who say the goal is humanity’s best bet on avoiding the most catastrophic outcomes of climate change by the end of the century. Venturing even 0.5 degrees past that threshold could drastically increase the frequency and severity of extreme weather, biodiversity loss, famine and water scarcity, as well as make it more likely that tipping points accelerate warming further, climate scientists say.
