Climate Tipping Points (2022)

Climate Tipping Points: Insights for Effective Policy Action ▪ Climate change report by the OECD , Organisation for Economic Co-operation and Development (December 2nd, 2022). Executive Summary: ▪ This report reviews evidence that overshooting +1.5°C (+2.7°F) may push the earth over several tipping points, leading to irreversible and severe changes in the climate system. ▪ If triggered, tipping point impacts will rapidly cascade through socio-economic & ecological systems , leading to severe effects on human & natural systems and imposing important challenges for human adaptation. ▪ Of particular concern are the likely collapse of the West Antarctic & Greenland ice sheets and the abrupt melting of permafrost grounds in the Arctic, which would result in additional sea-level rise and greenhouse gas releases, leading to more warming.
