Greenland Ice Sheet melt season starts
On April 25, 2024, a moderately strong melt event kicked things off early on the Greenland Ice Sheet. Since then, however, the melt season has been fairly typical. Snowfall in early June blanketed exposed ice, which will slow the onset of more intense melting and run off for the next few weeks. Overall, melting in Greenland has remained well above the 1980s and 1990s levels since 2013, but the 2012 season remains a distinct record.
