Satellite Record Reveals Arctic Melt Season Has Plateaued After Decades of Lengthening
Researchers said later autumn freeze-up drove the change, and the Arctic melt season is now about 40 days longer than in 1979.

The Arctic sea ice melt season has lengthened by about 40 days since satellite measurements began in 1979, but a new NASA-led study shows that this increase unexpectedly stopped around 2010, and the length of the melt season has remained roughly the same since then, NASA reported.
Satellite record reveals Arctic melt season has plateaued after decades of lengthening
For decades, Arctic sea ice has been melting earlier in spring and freezing later in fall, extending the melt season and contributing to widespread ice loss. A new NASA-led study published in Communications Earth & Environment has found that while the Arctic melt season has lengthened dramatically since satellite records began, that trend unexpectedly stabilized around 2010.
The melting season of the Arctic sea ice is today about 40 days longer than 1979. However, since about 2010 it has not been extended on average, but fluctuates strongly from year to year. A new analysis of satellite data indicates that thinner ice and changing cloud conditions shape the annual development more strongly. Greenbelt (U.S.A.).

NASA detects that the arctic thaw season ceased to elongate by 2010: 44 years of satellites point to a regime change in sea ice. The entry NASA detects that the arctic thaw stabilized since 2010 and forces to review the climate models first appears on Merca2.
The melting of the Arctic does not progress at exactly the same pace every year. It can accelerate for a decade, stabilize for several years and even show periods with less melting. But those variations do not mean that global warming is over. Research led by NASA scientists found a very clear example. Since satellite observations began in 1979, the season during which Arctic sea ice melts became approximately 40 days longer. However, since arou…
