Doomsday Glacier melting faster than expected
The gist
A new study says Antarctica's Thwaites Glacier could add 1.2 inches (30mm) to global sea levels by 2100.
The glacier holds enough ice to raise seas over half a meter.
How it unfolded
- Oct 14, 2026A new study says Thwaites might push global sea levels up by 1.2 inches (30mm) by 2100, double what scientists previously expected.
- Oct 15, 2026Scientists find the glacier is melting "more aggressively" than thought; Thwaites contributes around 4% to global sea level rise.
- Oct 15, 2026The study finds a 60% chance the ice will be unpinned from Mouginot Ridge by the end of the century, after which it is likely to retreat quickly down the sloping bedrock toward the next major ridge.
