In february 2026, the #SeaIce global extent was 4.5% below 1991-2020 mean. Since the beginning of records (1978):
- #Arctic, 3rd lowest monthly mean, with 4.8% less extent than normal (-712,597km²)
- #Antarctic, 26th lowest monthly mean, with 3.1% less extent than normal (-105,212km²)

In August 2025, the #SeaIce global extent was 8.4% below 1991-2020 mean. Since the beginning of records (November 1978):
- #Arctic, 8th lowest monthly mean, with 12,2% less extent than normal (-823 904km²)
- #Antarctic, 3rd lowest monthly mean, with 6.9% less exent than normal (-1 264 062km²)
Like for the MSG product, the MTG product is a level 3, hourly, sub-skin Sea Surface Temperature derived from Meteosat at 0° longitude, covering 60S-60N and 60W-60E and re-projected on a 0.05° regular grid, in GHRSST compliant netCDF format.
The MTG product benefits from the higher temporal and spatial resolution of MTG, but the output files have the same temporal and spatial sampling as the MSG product.
In June 2025, the #SeaIce global extent was 7.9% below 1991-2020 mean. Since the begining of record (november 1978):
- #Arctic, 2th lowest June monthly mean, with 6.4% less extent than normal (-733 404km²)
- #Antarctic, 3th lowest June monthly mean, with 9.1% less exent than normal (-1 255 507km²)
We have never measured so little #SeaIce around #Svalbard #Norway in mid November.
The #OSISAF satellite-based timeseries goes back to the late 1970s.
What an almost pleasant behavior of the global sea-ice extent
- almost reaching the bottom line (=previous minimum extents) from below.
