The Greenland Ice Sheet has seen an increase in extreme summer melting since the 1950s, with melt events becoming more frequent, widespread, and severe. Seven of the ten most extreme melt events have occurred since 2000, with meltwater up to three times higher than the average. Rising temperatures have increased Greenland’s meltwater production by approximately 25% during these more recent extreme events relative to 1950-1975. When compared with past melt events under the same large-scale atmospheric circulation patterns, present-day meltwater production is about 63% higher than mid-20th century levels, with the strongest increase observed in northern Greenland. Major record-breaking events in August 2012, July 2019, and July 2021 had no historical precedent in the satellite record. Under a high emissions scenario (SSP5-8.5), extreme meltwater events are projected to rise by as much as 370% by 2100, highlighting an intensification of extreme melting if today’s emissions continue without urgent reductions.
