Arctic sea-ice melt season is 7.5 days longer than in 1979

A University of Washington-led analysis found that the Arctic sea-ice melt season has lengthened by about 7.5 days since 1979, mainly because ice now forms later in autumn.

Cheatsheet for Arctic sea-ice melt season is 7.5 days longer than in 1979. Text equivalent is attached.

Why it matters: Longer periods of open water amplify warming because dark ocean reflects only about 7% of incoming sunlight, compared with roughly 60% to 90% for bright sea ice; the absorbed heat delays freezing and…
