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.
Analysis - Snow Today
Snow-covered area in May 2024 across the western United States was 56 percent above average (Table 1), at 156,000 square kilometers (60,000 square miles) of snow cover, ranking third highest in the 24-year satellite record. May snowfall brightened the snow cover in some areas while others darkened from lack of snowfall.
Analysis - Sea Ice Today
The sea ice cover in May 2024 was marked by an unusually early opening of eastern Hudson Bay. Overall, the rate of decline in the Arctic was near average for the month.
Analysis - Snow Today
Snow-covered area was 203 percent of average for April, ranking second highest in the 24-year satellite record. Despite a snowy April, snow cover days were below average because of a widespread slow start to the snow season. States in the north reported below-average snow water equivalent, while the opposite was true for states in the south.
Analysis - Sea Ice Today
April sea ice loss in the Arctic proceeded at a near-average rate overall, with the majority of ice losses in the Bering Sea and Sea of Okhotsk. In the Antarctic, sea ice grew faster than average, roughly evenly around the entire continent.
