Arctic sea ice is coming into its yearly low.
Daily extent: 4.574 million km2 on September 12, the lowest of 2026 so far. Rising since: 4.595, then 4.651.
If it holds: the 12th lowest minimum in the 48-year satellite record, and the highest minimum since 2022. Still 26% below the 1981-2010 average minimum; 4% above the 2016-2025 average.
Not confirmed. NSIDC calls the minimum in late September; a late dip resets the number.
Values: NSIDC Sea Ice Index v4.0 daily files, through Sept 14. Rank: my count.
