Monday ice update: The #Arctic and #Antarctic are more than two standard deviations below average (1981-2010). Both are also about 1.5 million square kilometers less than that baseline period.

Last month was the 2nd lowest #Antarctic sea ice extent on record for the month of October.

This was 1,760,000 km² below the 1981-2010 October average. Data from the @nsidc.bsky.social at nsidc.org/data/seaice_...

I'm up in Churchill with @polarbearsinternational.org keeping a close eye on the start of the freeze-up this year. No ice yet, and climate change is pushing this later & later into the season. This means polar bears have to spend more time on land before they can return to the sea ice to hunt seals.
Line graph time series showing daily Arctic sea ice extent in the Hudson Bay for 2026 compared to each year from 1979 to 2025. 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.

In less than a month the Arctic sea ice area has dropped 14 places to be 4th lowest which combined with the Antarctic's lowest causing global sea ice area to be the second lowest on record for the date.

Antarctic Sea-Ice Update:

As of October 27, Antarctic sea-ice extent is second lowest on record for the day, 3.98 standard deviations below the 1991-2020 average, and about 145,000 km² above the record daily low set in 2023.

Antarctic Sea Ice Decline Is Triggering Global Ocean Changes - Inside Climate News
A key layer of water around Antarctica is getting saltier, potentially shifting storm tracks and accelerating sea-level rise, new research shows.

“The shift reverses decades of freshening and echoes ocean changes usually associated with major global climate shifts over millennia but is now happening in just a few years.”

Check this out! These maps show temperature anomalies averaged by decade in the #Arctic for the month of October. This month is one of the fast warming for Arctic amplification trends. Heat is being transferred back into the overlying atmosphere from newly open water.

Data: doi.org/10.24381/cds...
Four polar stereographic maps showing Arctic near-surface air temperature anomalies for the month of October in 1986-1995, 1996-2005, 2006-2015, and 2016-2025. Most all areas are observing long-term warming, which is largest at the edges of the Arctic Ocean on the Atlantic and Pacific facing marginal seas.

September #Arctic sea ice extent since 1850 - comparison now updated through 2026

Please note that the reconstruction (SIBT1850 v2) is for the 15th of September, while the NSIDC is a monthly mean. You can read more about this data set at doi.org/10.7265/jj4s... via @nsidc.bsky.social.
Line graph time series of September 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.

Breaking News!
Code UFB!!!

As of October 13, Antarctic sea-ice extent is more than 5.0 standard deviations below the 1991-2020 daily average.

Under "normal" circumstances, the likelihood of this happening just by chance would be about 1-in-5,800,000.

Line graph time series of 2026's daily Antarctic sea ice extent compared to 1981-2010 climatological statistics. The graph shows the seasonal cycle, and ice-free conditions are indicated at 1 million square kilometers. Sea ice is currently below average for early October.
