In March 2025, Arctic sea ice hit its lowest annual peak on record. At the other end of the globe, Antarctic sea ice cover was the second-lowest on record that month.
That means that, overall, Earth’s sea ice reached a new record low in 2025.

#Winter #seaice in the #Arctic just hit a record low
After months of #polar darkness, the extent of sea #ice blanketing the Arctic this winter "fell to the lowest level on record, researchers announced this week... the smallest maximum extent in the 47-year satellite record, according to the National Snow and Ice Data Center.

Growing Ice
While much attention is given to the summer loss of sea ice, the birth of new ice in the fall is also critical. Ice loss in the summer leaves oceans warmer and waves larger since wind can blow across longer open stretches. Those warmer waters and more dynamic waves affect how ice forms once autumn sets in. Higher waves mean that ice tends to form in “pancakes” like those seen here. Pancake ice is small — typically under 1 meter wide — and can only be observed from nearby, since they’re smaller than typical satellite resolution. Only once there’s enough pancake ice to dampen the waves will the pieces begin to cement together to form larger pieces that will form the basis of the year’s new ice. (Image credit: M.

Sea ice extent in the Bering Sea likely (though not certainly) reached the highest of the season on March 26 in NSIDC data. Assuming the max extent of ~672,000 km² holds, this is 24 percent below the 1991-2020 average max extent and would effectively tie with 2017 for the fourth lowest seasonal maximum since 1979 ( the satellite era). @Climatologist49 @ZLabe
Qeqertalik Greenland, silent sunday everyone, it's so quiet up here. #silentsunday #greenland #qeqertalik #silent #sunday #northpole #north #travel #photography #iceburg #seaice #ice #sea
Sea ice extent in the Arctic reached its annual maximum late last week, and was the lowest annual maximum on record. The details in the latest post from the Alaska and Arctic Climate newsletter. @Climatologist49

It's been a while, so time for a new #intro :
I am a scientist at the meteo institute of Norway (MET Norway). I live in #Oslo . I work on #satellite, #climate and #SeaIce, with various institutions like #ESA and #EUMETSAT.
The banner pic of my profile is an artist view of a satellite flying above our Earth. This is the European CIMR satellite that will fly in the early 2030s.
I am trying to be better at #OpenScience, #music, and #Bass / #BassGuitar .
I post in English, French, and Norwegian.
I am @lavergnetho on Loops too. 
Sea ice extent in the Bering is at the highest of the season but remains below the 1991-2020 median. Southward expansion of the ice likely slow the past week in spite of the cold weather and north winds due to above normal sea surface temperatures south of the ice edge. #akwx #Arctic #SeaIce @Climatologist49 @ZLabe

=D cool hat! *gg*)
...so a paper covering a lot of work I did in Norway is out:
http://dx.doi.org/10.1002/gdj3.70001
It is an interesting one - done after my contract ended, I was surprised to be included.
"But you got a free paper!"
uh uh. Nope. I'm second author on all my own work.
...which acknowledges my technical work, and also removes acknowledgement of my strategic research thinking.
Anyway, I'm happy it is out now.
Sea ice extent in the Bering Sea increased slightly in the past week but remains below the 1991-2020 median. Bristol Bay remains ice-free. NWS Alaska Region sea ice analysis shows a larger area of moderate concentration ice in the Bering Sea than is typical for mid-March. @ZLabe @Climatologist49
Multi-satellite derived ice thickness around Alaska for the week ending March 13 relative to the previous 14 years (so very much a "modern era only" baseline). Bering Sea and near-shore Beaufort Sea the ice mostly thinner than usual. Chukchi Sea ice in better shape. #SeaIce #Arctic #akwx @ZLabe @Jdnome @Climatologist49
Over the whole month of February, average temperatures around the North Pole (80-90 degrees North) were around 12°C above the 1951-1980 average!

Global #seaice hit record low in February
The combined area of #ice around north and south poles hit new daily minimum in early February and stayed below previous record for rest of the month, reports EU's Copernicus #ClimateChange Service. "One of the consequences of a warmer world is melting sea ice," said deputy director, Samantha Burgess. "The record or near-record low sea ice cover at both poles has pushed global sea ice cover to an all-time minimum."
