The East Antarctic ice sheet appears to be more vulnerable than expected, due to a strong wind that brings warm air and blows away the snow. That is the conclusion reached by a team of climate researchers led by Jan Lenaerts (Utrecht University/KU Leuven) and Stef Lhermitte (TU Delft/KU Leuven), based on a combination of climate models, satellite observations and on-site measurements. Their conclusions will be published in Nature Climate Change on 12 December.
