The minimum daily extend for 2026 in #Antarctica was reached on 22/02/2026, with 2,862,440km².

The maximum daily extend for 2026 in #Arctica was reached on 07/03/2026, with 14,433,682km², which makes 2026 the year with the second lowest maximum, just after 2025.

In March 2026, the #SeaIce global extent was 6.8% below 1991-2020 mean. Since the beginning of records (1978):
- #Arctic, 1st lowest monthly mean, with 5.7% less extent than normal (-856,735km²)
- #Antarctic, 14th lowest monthly mean, with -10.1%> less exent than normal(-441,262km²)
