Global impacts, especially loss and damage, from cryosphere feedbacks will be largely permanent on human timescales, beyond adaptation limits for billions living in coastal or mountain-dependent regions if carbon emissions overshoot 1.5°C. This session outlined the latest science on projected feedbacks from ice sheets and glaciers in the context of implementation timeframes. Dr. Florence Colleoni is from the Italian National Institute of Oceanography and Applied Geophysics, and serves as co-chief officer of the new SCAR scientific research program INSTANT (Instabilities and Thresholds in Antarctica).
