Scientists warn of permanent cryosphere damage if 1.5C target is missed

Original: Cryosphere faces permanent damage when world overshoots 1.5C, scientists warn

A new UN-backed report warns that even temporary overshoot of the Paris agreement's 1.5C warming limit could cause lasting damage to the world's frozen regions, including glaciers, permafrost and polar ice sheets. Scientists say some changes to the cryosphere would be irreversible on human timescales, reinforcing calls for rapid emissions cuts ahead of the next round of global climate negotiations.

Why now: The release of a major UN-backed report highlighting irreversible ice loss is prompting fresh debate over climate targets.
