Greenland Ice Sheet Today - National Snow and Ice Data Center

Overview of ConditionsConditions in ContextAcknowledgementsSurface melting on the Greenland ice sheet ramped down at a near-normal pace in the weeks following the major melt event of early August (Figure 1). Only a few minor late-season melt events occurred in September and October. Overall, melting on the Greenland ice sheet for 2019 was the seventh-highest since 1978, behind 2012, 2010, 2016, 2002, 2007, and 2011 (Figure 2). Since 2000, the ice sheet has experienced a general increase in melting, with melt-day area for 2019 totaling 28.3 million square kilometers (10.9 million square miles) for the season. Melting was observed over nearly 90 percent of the island on at least one day, reaching the Summit Station and much of the high-altitude areas. It was particularly intense along the northern edge of the ice sheet, where compared to the 1981 to 2010 average, melting occurred for an additional 35 days. The number of days with melting was slightly above average along the western flank of the ice sheet as well, with about 15 to 20 more days...
