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».
Tipping elements within the Earth system are increasingly well understood. Scientists have identified more than 25 parts of the Earth’s climate system that are likely to have “tipping points” – thresholds where a small additional change in global warming will cause them to irreversibly shift into a new state. The “tipping” of these systems – which include the Atlantic Meridional Overturning Circulation (AMOC), the Amazon rainforest and the Greenland ice sheet – would have profound consequences for both the biosphere and people. More recent research suggests that triggering one tipping element could cause subsequent changes in other tipping elements, potentially leading to a “tipping cascade”. For example, a collapsed AMOC could lead to dieback of the Amazon rainforest and hasten the melt of the Greenland ice sheet.
Global carbon dioxide emissions from energy use and industry could peak as soon as this year, according to Carbon Brief analysis of figures from the IEA.
