UN report: irreversible climate damage locked in even if warming peaks at 1.5C

A new UN report warns that climate change impacts are compounding due to inaction, and that even if global warming peaks at 1.5C, the damage will be irreversible. The report underscores the permanence of harm already underway, challenging assumptions that limiting warming avoids long-term degradation. This raises the stakes for policy and adaptation, though specific regional impacts remain unspecified.
