A new study shows the East Antarctic Ice Sheet, once thought to be stable, may be melting faster than expected.

Antarctica’s melting ice, which has caused global sea levels to rise by at least 13.8 millimeters over the past 40 years, was long thought to come from primarily one place: the unstable West Antarctic Ice Sheet. Now, scientists studying 40 years of satellite images have found that the East Antarctic Ice Sheet—considered largely insulated from the ravages of climate change—may also be melting at an accelerating rate. Those results, at odds with a large 2018 study, could dramatically reshape projections of sea level rise if confirmed.
