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.

Time series plot of the autumn (September-November) average temperature each year across all land areas north of 60N 1950 to 2023 and an estimate of the time varying average. There was no significantly trend in autumn temperatures until the early 1990s but has been increasing rapidly in the 21st century.

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

Four panel graphic showing the 50-year change in seasonal average temperature 1974 to 2023 in and around Alaska. Upper left, winter; upper right, spring, lower left, summer and lower right, autumn. Temperatures changes are generally largest in north and northwest Alaska, reflecting the importance of sea ice changes.

Not much of a display last night but I finally got the gear out for some time lapse. #Nunavut #Arctic #Aurora

A time lapse of a starry night. The camera pans to the right and follows the stars as they sweep across the sky. A small amount of aurora appear twice in the clip.

✧ Columbidae ✧

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

Plots: https://zacklabe.com/arctic-sea-ice-extentconcentration/

Line graph time series of 2023's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2023 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between October and January.

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
@Climatologist49

Top: change in the December average temperature (ºF) between 1973 and 2022 in and around Alaska. Bottom: change in December total precipitation (percent) in and around Alaska between 1973 and 2022.

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

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

November 2023 #Arctic sea ice extent was statistically tied for the 7th lowest on record...

This was 1,040,000 km² below the 1981-2010 average. November ice extent is decreasing at about 4.73% per decade. Data: https://nsidc.org/data/seaice_index

Line graph time series of Arctic sea ice extent for every November from 1978 through 2023. There is interannual variability and a long-term decreasing trend.

#ColonialViolence in #Scandinavia countries and the religious and economic war on #Indigenous #Sami populations are the stories of such #books as Stolen by Ann-Helén Laestadius, The End of Drum-Time by Hanna Pylväinen, and Forty Days Without Shadow by Olivier Truc. I just finished #reading Truc's book. Like the Americas, #Australia and everywhere else subjected to #colonialism, the #racism, #misogyny and #greed all look the same and have same outcomes.

#Arctic sea ice has been unusually slow to reform across the Hudson Bay (Canada) so far this freeze season...

Each line represents one year from 1979 (purple) to 2022 (white). 2023 is in red. Data from https://nsidc.org/data/seaice_index

Line graph time series showing daily Arctic sea ice extent in the Hudson Bay for 2023 compared to each year from 1979 to 2022. There is a large seasonal cycle on this graph and a long-term decreasing trend for days during the melt season from June to December.

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).

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

#ClimateCrisis #Weather #Arctic #Heatwave
The astonishing heatwave in the far North of Canada, Nov 2023, continues

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

Hope you have a great weekend! Here's your Friday ice update - #Arctic sea ice extent is currently the 4th lowest on record (JAXA data)...

• about 280,000 km² below the 2010s mean
• about 770,000 km² below the 2000s mean
• about 1,470,000 km² below the 1990s mean
• about 1,980,000 km² below the 1980s mean
