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.

As of February 22, over twenty Stand Up for Science protests are scheduled for March 7 throughout the United States. The protests are being organized by fellow scientists who are concerned about the Trump administration’s feelings and actions towards science (see Robles-Gil, 2025 in Science), includ

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. ...
