UN reports warn that climate change is causing irreversible large-scale damage to Earth's glaciers and ice sheets.

What it means

Two UN-backed reports, likely from the World Meteorological Organization and UN Environment Programme, warn that exceeding 1.5°C of global warming—even temporarily—will cause irreversible large-scale damage to Earth's frozen regions, including glaciers, ice sheets, sea ice, and permafrost. This means that some ice loss will be permanent and cannot be reversed, with consequences for sea level rise and water supplies.

Accuracy & sourcesGrounded

The claim is based on official UN-backed scientific reports, reported consistently by multiple reputable news outlets (AFP, The Guardian, etc.) that cite the reports directly. The reporting is close to the primary source, and the consensus across outlets supports the claim's solidity, though the exact report titles are not specified in the highlight.
