And now we know that the volume of #Arctic sea ice also dropped to a record low in October (zacklabe.com/archive-2025/).

It's been a historic fall in the #Arctic, which is already a season of rapid climate change. Not good.

The Chukchi Sea is now iced-over and attention turns to the Bering Sea. Recent cold and windy weather has driven a rapid increase in sea ice extent in NSIDC data. Total extent is the highest for Dec 6 since 2021. Upcoming weather pattern change will slow ice extent increase. #akwx #Arctic #SeaIce

Ice-over of the Chukchi Sea (northwest of Alaska) on December 3 as open water area dropped to under 5 percent of the basin in NSIDC data. Similar timing to last year but earlier than most autumns 2013-2023. Of course, still later than most years before 2002. #akwx #Arctic #SeaIce
Bar plot of the first date in the autumn 1978-2025 when less than 5 percent of the Chukchi Sea basin (as defined by NSIDC) was still open water. Also show is a smoothed 11-year centered average.

The incredible tragedy for #ArcticScience of NOAA shutting down their #methane monitoring data. 5th May 2025 is the last data we'll ever get.

Friday ice update - #Arctic sea ice extent is currently the 6th lowest on record (JAXA data)

• about 330,000 km² below the 2010s mean
• about 1,490,000 km² below the 2000s mean
• about 2,370,000 km² below the 1990s mean
• about 2,580,000 km² below the 1980s mean

Line graph time series of 2025'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 2024. 2025 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 August and November by looking at the decadal average line positions.

Sea ice extent in the Chukchi Sea (northwest of Alaska) in September was lower than last year but higher than most years since 2007 in NSIDC data. Nonetheless, the decrease since 1980s is dramatic. #akwx #Arctic #SeaIce #ClimateChange

End of an era and a sad day for those that care about Arctic work done in the best ways possible. 😢 Nonetheless "… the goal of broadening participation in Arctic-focused research, education, and policy is still an important mission to achieve." #Arctic
A Final Message from the Arctic Research Consortium of the U.S. (ARCUS) After nearly four decades of service to the Arctic research community, the Arctic Research Consortium of the United States (ARCUS) has now reached its sunset. This will be our final message to the community. On behalf of the ARCUS Board of Directors and all ARCUS staff, we want to thank you for the many years of collaboration, support, and partnership that made ARCUS possible. We have enjoyed working with this community immensely and believe that the goal of broadening participation in Arctic-focused research, education, and policy is still an important mission to achieve.
