Greenland mass loss
WebThe Greenland Ice Sheet has contributed substantially to sea-level rise over the past few decades. Since 1972, approximately two-thirds of the ice sheet’s contribution to sea-level rise resulted from increased glacier flux with the remaining one-third from anomalous surface melt ().Before 2000, anomalous ice discharge was the dominant driver of mass … WebNov 25, 2024 · The ice mass loss from the three outlet glaciers constitutes a large and ‘representative’ proportion of the total ice mass loss for the Greenland Ice Sheet. “The ice mass loss here gives a very good picture of the situation in the rest of Greenland and the Arctic region, and guides us on what the likely future scenario will be,” says ...
