Arctic Melt Season Length Levels Off

Two Arctic maps compare changes in melt season length by decade. Red indicates areas where the season grew longer; blue, where it grew shorter. The 2000–2009 map is mostly dark red. The 2010–2023 map shows a mix of lighter red and blue, indicating smaller changes.

While the sea ice melt season has lengthened dramatically in most of the satellite era, the trend unexpectedly stabilized around 2010.
