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.

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.

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.

the starkest warning yet that human activity is pushing Earth into a climate crisis that could threaten the lives of up to 6 billion people this century, stating candidly: “We are afraid of the uncharted territory that we have now entered.” Writing in the journal Biosciences, the coalition of 12 researchers, spanning North America, Europe and Asia, state in unusually stark language: “As scientists, we are increasingly being asked to tell the public the truth about the crises we face in simple and direct terms. The truth is that we are shocked by the ferocity of the extreme weather events in 2023.”

Previously, anthropogenic ecological overshoot has been identified as a fundamental cause of the myriad symptoms we see around the globe today from biodiversity loss and ocean acidification to the disturbing rise in novel entities and climate change. In the present paper, we have examined this more deeply, and explore the behavioural drivers of overshoot, providing evidence that overshoot is itself a symptom of a deeper, more subversive modern crisis of human behaviour. We work to name and frame this crisis as ‘the Human Behavioural Crisis’ and propose the crisis be recognised globally as a critical intervention point for tackling ecological overshoot. We demonstrate how current interventions are largely physical, resource intensive, slow-moving and focused on addressing the symptoms of ecological overshoot (such as climate change) rather than the distal cause (maladaptive behaviours). We argue that even in the best-case scenarios, symptom-level interventions are unlikely to avoid catastrophe or achieve more

En cette nouvelle année, il est indispensable de faire le bilan de la production d’électricité en 2022. Pour cela, nous comparerons l’Allemagne, souvent mise en avant par de nombreux politiques français pour son avance dans la transition énergétique, et la France, que ces mêmes politiques disent en retard. Attention, l’électricité ne représente que 20 à 25% de l’énergie consommée. De plus, l’empreinte carbone des habitants tient compte des importations (soit 50% pour un Français). Les émissions de CO2 présentées dans cet article ne concernent donc que celles liés à la production d’électricité.

Ecosystems rely on interconnectedness — bees pollinate the flowers, predators eats prey, and so on. But these webs, though highly evolved, can be delicate.

Climate scientists have expressed shock at the UK’s smashed temperature record, with the heat soaring above 40C for the first time ever on Tuesday. Researchers are also increasingly concerned that extreme heatwaves in Europe are occurring more rapidly than models had suggested, indicating that the climate crisis on the European continent may be even worse than feared. Temperature records are usually broken by fractions of a degree, but the 40.2C recorded at Heathrow is 1.5C higher than the previous record of 38.7C recorded in 2019 in Cambridge.

Long before the current political divide over climate change, and even before the U.S. Civil War (1861-1865), an American scientist named Eunice Foote documented the underlying cause of today’s climate change crisis. The year was 1856. Foote’s brief scientific paper was the first to describe the extraordinary power of carbon dioxide gas to absorb heat – the driving force of global warming. Carbon dioxide is an odorless, tasteless, transparent gas that forms when people burn fuels, including coal, oil, gasoline and wood.
