What to know

  • Arctic sea ice extent has fallen to its 10th lowest level on satellite record as of mid-September 2026, according to JAXA data.
  • Current extent is about 2.78 million km² below the 1980s mean, reflecting a long-term decline in Arctic ice coverage.
  • Regional variability exists: the Beaufort Sea saw rapid ice concentration decline after a slow melt start, while Laptev Sea ice remained persistent.

    Beaufort Sea shows rapid ice concentration decline after slow melt start

    Labe reports that after a very slow start to the melt season in the Beaufort Sea, lower concentration ice gave way quickly to large departures in the region. Laptev Sea ice has also been persistent this year.
