Global impacts, especially loss and damage, caused by cryosphere feedbacks from emissions overshoot over 1.5°C will be largely permanent on human timescales, beyond adaptation limits for billions living in coastal or mountain-dependent regions. This session outlined the latest science on projected feedbacks from ice sheets and glaciers in the context of implementation timeframes, such as the UNFCCC Global Stocktake which just completed an Inter-sessional meeting in Bonn. The presenter at this COP27 event was Dr. Florence Colleoni, Italian National Institute of Oceanography and Applied Geophysics, co-chief officer of the new SCAR scientific research program INSTANT (Instabilities and Thresholds in Antarctica).
