The Arctic sea ice cover in June 2024 retreated at a below average pace, leading to a larger total sea ice extent for the month than in recent years. Many areas of open water have developed along the Arctic Ocean coast.
Analysis - Ice Sheets Today
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.
