The Greenland Ice Sheet lost 5,091 sq km (1930 sq miles) of area between 1985 and 2022, according to a study in the journal Nature published on Wednesday, the first full ice-sheet wide estimate of area loss on that scale. This shrinkage reflected the 1,034 gigatonnes (1.034 trillion kg.) of ice that have been lost as glaciers retreated, shedding ice through "calving" - when ice chunks break off from a glacier - at their terminating ends.

It suggests previous estimates of changes to the Greenland Ice Sheet's mass balance - how much snow and ic...
