Sea ice extent as of March 30 in the Bering Sea is almost exactly at the 1991-2020 median and 30 percent higher than the end of March last year in NSIDC data. Ice loss in Kuskokwim and Bristol Bays has been notable in the past week, while in the central Bering Sea, the ice edge has been pushed south a bit by moderate north winds. #akwx #Arctic #SeaIce #Spring2024

Being Sea 2024 maximum sea ice extent has been reached in NSIDC data. The max extent almost exactly the same as last year but occurred a month later. The max extent was about 14 percent below the 1991-2020 average and was the latest since 2016. #akwx #Arctic #SeaIce #climate

Bering Sea ice extent is now at or very close to the seasonal maximum in NSIDC data. The pack ice edge is not far northeast of St. Paul Island in Pribilof Islands. However, the cold north wind pattern is ending and sustained south to southeast winds and much milder temperatures will spread over the central Bering Sea early this week, pushing the ice edge back north. #akwx #Arctic #SeaIce

Sea ice extent in the Bering Sea as of March 2 is the highest so far this season in NSIDC data. Extent is now higher than this date last year and is typical for the first week in March. The ice edge remains well to the north and northeast of the Pribilof Islands. Reports in recent days from Nome to St. Lawrence Island note poor ice quality with ice appearing thin and weak. #akwx #SeaIce #Climate #Arctic

Sea ice extent in the Bering Sea remains a bit below the 1991-2020 median in NSIDC data There's been only limited variation in the position of the ice edge the past four weeks due to the frequently changeable winds. Maximum ice extent is typically reached in March, so there's still time for expansion, though with significant storm likely in the western Bering Sea later this week, bringing south to southeast winds, the clock is ticking. #akwx #Arctic #SeaIce

Sea ice extent in the Bering Sea has decreased a bit in the past week due to storminess and southeast winds. Current extent is about 17 percent below the 1991-2020 median in NSIDC data. There is still plenty of time for ice to expand: the maximum ice extent in the Bering Sea is typically reached between late Feburary and late March. #akwx #Arctic #SeaIce

Bering Sea sea ice extent increase stalled in the past week in NSIDC data due to a change in the weather pattern, with more storminess north of 60°N. NWS Alaska Region analysis shows sea ice has been almost completely lost in Bristol Bay. Upcoming week will be stormy but effects on sea ice extent in the Bering will depend on details of the storm tracks.

The Chukchi Sea, northwest of Alaska, is now almost completely iced-up, i.e. there is very little open water remaining. From NSIDC data, open water was reduced to less than 5 percent of the basin as of December 15. This is very much in keeping with recent years' timing of ice-over but a far cry from the 1980s. In the 46 years of satellite data, the average date of ice-over in the Chukchi Sea has increased by nearly four weeks. #akwx #Arctic #SeaIce #ClimateChange

The Yale Program on Climate Change Communication has released the autumn 2023 update to their "Global Warming’s Six Americas", documenting US attitudes toward climate change. From this graphic, it's perfectly clear that attitudes are locked in, spite of all that has happened in the past five years. 😢

Sea ice near Alaska is slowing increasing but remains below even recent years typical levels. Chukchi Sea #SeaIce extent is well below last year at this point is the 7th lowest for December 2nd in 46 years of NSIDCI data. Open water at 72ºN (NW of Utqiaġvik) less than 3 weeks from winter solstice is just sad. Bering Sea ice extent is also below typical levels but finally starting to see growth on the Chukotka coast. #akwx #Arctic #Climate

Sea ice in October 2023 north of Alaska and the Russian far northeast coast was less extensive than last year and of course far below typical late 20th century typical levels. The Pacific side of the #Arctic is a very different place environmentally in the autumn than it was even 30 years ago. #akwx #Climate #Autumn2023

Sea ice extent near Alaska remains below even modern era typical levels for this point in the season. The Beaufort Sea is still more than 50 percent open water in NSIDC data, only the second time in the 45-year satellite era there's been so much open water so late in the season. Chukchi Sea #SeaIce extent is not as extremely low but still well below normal. South winds returning to the Chukchi this week, so could even be some ice retreat. #akwx #Arctic #Climate

Utqiaġvik back in the day usually did not go three weeks in a row in the summer without the temperature falling to freezing or below, and in some summers not even a week. All that has changed. The average length of the freeze free season at Alaska's northernmost community has tripled since the 1940s. #akwx #ClimateChange

Sea surface temperatures around Alaska are now almost entirely near to above average in NOAA/PSL/ESRL data for the week ending October 6. This is a big change in the eastern Bering Sea, where #sst were below average all summer. Complete lack of sea ice driving the positive departures in the Beaufort Sea. Northern Gulf of Alaska slightly above the 1991-2020 average. #akwx #Arctic #Oceanography

Sea ice extent near Alaska has reached the low point for the year. The minimum combined Beaufort and Chukchi Seas ice extent in NSIDC data was reached on Sept 20 and is the second lowest in the 45 years of satellite observations. Sept 23 NWS Alaska Region ice concentration analysis shows no significant ice within ~250 miles (400km) of the Alaska coast. Prior to the 1990s, in some summers, #SeaIce would never entirely clear the northern Alaska coast. #akwx #Arctic #Climate
