La collapsologie est un courant de pensée transdisciplinaire apparu dans les années 2010 qui envisage les risques d’un effondrement de la civilisation industrielle et ses conséquences.
En France, l’étude d’un possible effondrement de la civilisation « thermo-industrielle » est initiée par l’Institut Momentum co-fondé par Yves Cochet et Agnès Sinaï. Ces derniers définissent l’effondrement comme « le processus irréversible à l’issue duquel les besoins de base (eau, alimentation, logement, habillement, énergie, etc.) ne sont plus fournis (à un coût raisonnable) à une majorité de la population par des services encadrés par la loi».
If Nature were to draw a map of the world, what would it look like? One Earth presents a novel biogeographical framework called Bioregions 2023, which delineates 185 discrete bioregions organized within the world's major biogeographical realms.
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.
Au premier semestre 2021, la déforestation en Amazonie a augmenté de 17 % par rapport au premier semestre 2020. Alors que la saison sèche s’ouvre au Brésil, le nombre d’incendies dépasse déjà celui de l’année dernière à la même période. Ces chiffres laissent présager de nouveaux records d’incendies au Brésil cet été.
A new report has found that by 2025, the world must remove 1 Gigatonne, or 1 billion tonnes, of carbon from the atmosphere to keep global warming within the Paris Agreement target of 1.5°C. However, projects in development will remove only a fraction of this. The report says, “Without action to deliver 1 Gigatonne (Gt) of negative emissions globally by 2025, keeping global warming within the Paris Agreement target of 1.5°C cannot be achieved.”
A new study has found that if greenhouse gas emissions are not curbed urgently, a third of endemic species on land and half in the sea will become extinct, causing a collapse of biodiversity. According to the study, 92% of all endemic species on land and 95% of those in the ocean will decrease in numbers or even disappear under current emissions levels, which will increase global temperatures by 3 degrees Celsius by 2100.
The climate crisis is causing ancient permafrost to thaw, which could unleash viruses and bacteria that have been dormant for thousands of years, presenting a potentially catastrophic risk to humans and ecosystems alike.
