Reconstructing October #Arctic sea ice extent since 1850... Data from @nsidc.bsky.social at doi.org/10.7265/jj4s...

Line graph time series of October Arctic sea ice extent for every year from 1850 through 2026. Two datasets are compared in this time series. The Walsh et al. 2019 reconstruction is shown with a solid blue line. The NSIDC Sea Ice Index v3 is shown with a dashed red line only for the satellite era. There is large interannual variability and a long-term decreasing trend over the last few decades.

Friday ice update - #Arctic sea ice extent is currently the 5th lowest on record (JAXA data) • about 460,000 km² below the 2010s mean • about 1,240,000 km² below the 2000s mean • about 1,860,000 km² below the 1990s mean • about 2,140,000 km² below the 1980s mean More: zacklabe.com/arctic-sea-i...

Line graph time series of 2026'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 purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2025. 2026 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 December by looking at the decadal average line positions.

My monthly #Arctic temperature graphics are now updated for data through October 2026. Warmer than average conditions were found over the entire Arctic Ocean during the month. Check them out at: zacklabe.com/arctic-tempe... #DataViz #SciComm #OpenScience #OpenData

This is from the north of Finland, a region experiencing a tourism boom (on fossil fuels of course) for snow and Santa Claus. Some tourists cancel their trip last minute, if there is no snow on the ground. Meanwhile, the #Arctic is warming multiple times faster than the rest of the world.

Auch 135 km nördlich des Polarkreises sind Snowfarmer am Werk.

Zwei Pistenraupen präparieren eine schmale, künstlich beschneite Skipiste, die sich durch eine ansonsten schneefreie, braune und felsige Landschaft zieht. Die Piste verläuft leicht geschwungen einen Hang hinab. Entlang der Strecke stehen mehrere Masten. Im Vordergrund und an den Seiten ist deutlich der Kontrast zwischen dem weißen Schnee und dem braunen Untergrund zu erkennen. Am rechten Bildrand sind Social-Media-Symbole und Zahlen eingeblendet.

Sea ice extent is increasing in the Chukchi & Beaufort Seas. Chukchi Sea ice extent is well above the 1991-2020 median in NSIDC data, mostly from increases north of Chukotka. Ice-over of the Beaufort Sea will occur this week. Meanwhile, still hardly any ice in the Bering Sea. #akwx #Arctic #SeaIce

Sea surface temperature difference from the 1991-2020 baseline average around Alaska for the week ending November 6. Gulf of Alaska notably warmer than average. Western and central Bering Sea cooler than average. Mixed in the eastern Bering Sea. Data courtesy NOAA/PSL/ESRL. #akwx #Arctic #SST

Map centered on Alaska showing sea surface temperatures (ºC) for the week of October 31 to November 6 as the difference from the 1991-2020 average.

October 2026 was warmer than the 1991-2020 baseline average over more than 90 percent of the Arctic (land & seas poleward of 60°N) in ERA5 reanalysis courtesy @copernicusecmwf.bsky.social. For the Arctic this was third warmest October; only 2020 & 2025 had a higher average temp. #Arctic #Climate

🐻‍❄️ It’s the last day of Polar Bear Week. @polarbearsinternational.org runs live cams from Churchill during the fall migration, so you can watch the bears waiting on the shoreline. 📸 : Can Geo Photo Club / Shaun Antle #PolarBearWeek #PolarBears #Churchill #HudsonBay #Arctic

Two polar bears are resting closely together on a dark, textured ground. Their white fur contrasts with the surrounding landscape.

A large polar bear stands on rocky terrain, with a young polar bear peeking out from underneath. The background features a mix of snow and earth.

A polar bear sits on a rocky outcrop, gazing at a rusty, abandoned ship in the Arctic sea under a cloudy sky.

The seeds of a novel are there long before you recognize them. I recently found a dream fragment from ±10 years ago: salmon, trains, young people, the North. Years later, those threads found their way into Rail: A High Speed Adventure. www.mkbcstudio.com #Arctic #BookSky #Ecofiction #Salmon #Writing

🔥 Arctic fires leave the ground warmer After fires, the land surface in boreal forests warmed by 0.53 K on average, and in tundra by 0.44 K. Fire in the far north adds its own heat to a region already warming fast. 🔗 doi.org/10.1029/2026gl125479 #Arctic #Wildfire #Climate 🧪
