A 1.5°C overshoot could leave lasting ice loss.
A later drop in temperatures would not necessarily mean some lost ice comes back at the same pace. Two reports released jointly on Nov. 2 warn that a temporary rise past 1.5°C could cause widespread losses in glaciers, ice sheets, sea ice and permafrost. They say some of the damage could be difficult to reverse for generations. The effects reach far beyond frozen regions: one report links melting glaciers, sea ice and permafrost, along with rising sea levels, to flood risks, water shortages and hazards in mountain areas. The reports say losses can still be limited if the overshoot is kept as small as possible through deep emissions cuts and expanded carbon removal.
