The autumn 2023 average temperature for the Arctic land area (land north of 60°N) was the highest since 1950 (and almost certainly a very long time before that). The trend since the early 1990s an astonishing 1.6F (0.9C) per decade.This follows the warmest summer on record. For the combined land and sea north of 60°N this was the third warmest autumn.

Update to the 50-year seasonal temperature changes in and around #Alaska (ºF), now for 1974-2023, all from ERA5 courtesy of ECMWF/Copernicus. The incredible warming in the autumn across northern Alaska is driven by the loss of sea ice. The comparatively modest warming in summer in part reflects the unimportance of snow and ice in that one season. Spring slight cooling in the southeast Interior stands out. #akwx #Arctic #Climate #ClimateChange

Columbidae is a bird family consisting of doves and pigeons. In English, the smaller species tend to be called doves and the larger ones pigeons, but this distinction is not always consistent and scientifically there is no separation between them. Pigeons and doves are distributed everywhere on Earth, except for the driest areas of the Sahara,...
Hot off the digital press:
September through November 2023 temperature departures from the 1991-2020 baseline around the Arctic. Northern Canada, northern Alaska and parts of western Siberia especially mild. Only Scandinavia and Fram Strait region significantly cooler than average. Overall this ranks as the third mildest autumn since 1950 for the #Arctic (poleward of 60N).

Hope you have a great week! Here's your Monday ice update - #Arctic sea ice extent is currently the 7th lowest on record (JAXA data)...
• about 140,000 km² below the 2010s mean
• about 680,000 km² below the 2000s mean
• about 1,370,000 km² below the 1990s mean
• about 1,830,000 km² below the 1980s mean
Alaska and vicinity 50-year changes in December average temperature (top) and total precipitation (bottom). The massive increase in both temps and precip in the western Chukchi Sea south through the Bering Strait is tied to radically decreased sea ice. Decreased precip in NW British Columbia and parts of SE Alaska coupled with increases in SW Alaska look like multi-decade variations in prevailing the storm track. #ClimateChange #Alaska #Arctic
Nerd alert: That great buster of early winter temperature forecasts, the dreaded "black stratus", is creeping south toward Fairbanks. So called because, as you can see, on old-school gray scale infrared satellite pixs, these low clouds appears darker than than surrounding land because the cloud tops are warmer than ground. Where/when these clouds move over, valley temperatures can rise 10 to 20F in a few hours while hills might even cool a little. #Arctic meteorology fun. #akwx @Climatologist49
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
"“If they close the border, it will be unbearable.” What Russians think about the last open checkpoint"
Sea surface temperatures relative to the 1991-2020 normal in the eastern Bering Sea have increased in recent weeks while the western Bering has cooled (relative to normal). It's going to take a while to dissipate ocean surface heat and get sea ice growth underway. Above normal ocean temperatures north of the Bering Strait outline areas without significant sea ice. Little change in the Gulf of Alaska where #sst remain near to above normal. #akwx #Arctic

Prudhoe Bay area, Alaska warmest November on record. The Deadhorse Airport (North Slope, Inupiat county) reported a November 2023 average temperature of 13.0F (-10.6C). That’s more than 11F (6C) above normal. The previous mildest November was 2017 with an average temperature of 11.1F (-11.6C). Climate observations in the Prudhoe Bay area since late 1968. #akwx #Arctic #Climate #Autumn2023
Utqiaġvik, Alaska autumn 2023 ties for the second warmest (Sep-Nov) in the past 103 years. This follows the warmest summer of record. The autumn trend since the early 1990s is stunning: a change in the average temperature of a bit over 10F (6C) in 30 years, most of which is attributable to the collapse of autumn sea ice near Alaska, especially the Chukchi Sea. #akwx #Arctic #ClimateChange #ClimateCrisis

In a position paper issued just before the start of a major international #ClimateChange conference, the #Inuit #CircumpolarCouncil listed 5 major recommendations for ways that the “stark warnings” that the #Indigenous people of the #Arctic have been issuing for decades can be addressed. The council includes #Inupiat and #Yupik representatives.
The avg temp for the entire arctic region is an astonishing 6.8oC above the avg for the date - astonishing because the arctic is such a large area; it is quite common to have heat or cold waves over smaller areas

Sea ice extent in the Bering Sea is highly variable early in the season and depends mostly on the weather and timing of storms. The total extent as of Nov 26 is below the 2006-2022 average. Shallow bays and near river mouths are the first areas to freeze, hence the ice in Norton Sound and near the Yukon River delta. The Gulf of Anadyr usually freezes later than the Alaska coast but near complete absence of #SeaIce this late in the fall is unusual.

It's chilly in Denmark today but there is a massive warm anomaly over #Greenland and the North American part of the #Arctic.
At this time of year, that often means heavy #snow, and sure enough @polarportal 's #weather page shows a long filament of moist air stretching from the mid-latitudes to SW Greenland - surely one of the wetter corners of the planet.- where it is nourishing the #IceSheet.
Sea surface temperature departures from 1991-2020 average for the week ending November 24 around Alaska are near to above normal. The southern Bering Sea is especially "warm". The remaining sea ice free areas in the Chukchi Sea also stand out with significantly above average #sst. Data from NOAA/PSL/ESRL.

Sea ice concentration analysis for Wednesday and the same date last year from the National Weather Service Alaska Region Sea Ice Program. Much less ice in the southern Chukchi and Bering Seas currently than this date last year. November 15 and effectively no ice in Kotzebue Sound is especially shocking, even by recent norms. #akwx #Arctic #SeaIce #Climate

Sea ice is gradually expanding in the seas north and west of Alaska. Very unusually for this late in the season, there's still some open water in parts of Beaufort Sea, while Chukchi Sea ice extent remains below the 1991-2020 median in NSIDC data. Nearshore Bering Sea #SeaIce is typical for recent years for the second week in November. Ongoing storminess will likely slow down/reduce ice for a few days in the Chukchi and Bering Seas. #akwx #Arctic #Climate
Sea surface temperatures departure from average around Alaska for the week ending November are almost entirely above normal, with the western Bering Sea especially warm compared to the 1991-2020 average. This will change in the north as #SeaIce forms but still, considerable ocean heat in the southern Chukchi and northern Bering Seas will slow down ice formation. Data courtesy NOAA/PSL/ESRL. #akwx #Arctic #sst
Very large portions of the #Arctic observed temperatures more than 5°C above the 1981-2010 reference period last month! This was especially prominent in areas of missing sea ice.
