New model doubles projected sea level rise from Antarctica's Thwaites Glacier
Warm water penetrating miles beneath the ice could add 30 millimeters to global sea levels by 2100
A new computer model from researchers at the University of California, Irvine and NASA's Jet Propulsion Laboratory predicts that Antarctica's Thwaites Glacier could raise global sea levels by as much as 30 millimeters by 2100, double earlier projections, even without additional warming of the climate. The findings, published in Nature Communications, suggest previous models underestimated the glacier's retreat because they treated the boundary between grounded and floating ice too narrowly.
