00:00NASA has a new update on Arctic sea ice, and the numbers are sobering.
00:04This year's summer minimum came on September 12th, at about 4.6 million square kilometers.
00:10That is tied with 2008, 2010, and 2025, for the 10th lowest minimum in the satellite record.
00:17Every summer from 2007 through 2026 ranks among the 20 lowest.
00:22Winter is changing, too.
00:24The March 2026 peak tied March 2025 for the lowest winter maximum on record.
00:29The ice itself is changing as well.
00:32Multi-year ice, which survives summer melt, has declined significantly,
00:36and thinner first-year ice now dominates more of the Arctic.
00:40Here is a surprise.
00:41Summer losses have been comparatively steady over the past decade,
00:45and NASA researchers say extra cloud cover, which reduces sunlight reaching the ice, is one factor.
00:51Natural variability matters, but the summary says natural swings cannot fully explain the persistent decline.
00:58Projections say the Arctic could be essentially free of summer sea ice at least once before the middle of this
01:04century.
