Clear losses of #Arctic sea ice concentration are found in October. Some of the largest declining trends extend from parts of the East Siberian Sea to the Chukchi Sea, as well as the Kara Sea.

I'm up here in Churchill with Polar Bears International (https://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 and 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.

The last three months really highlight just how widespread the unusually warm sea surface temperatures are found. In addition El Niño, there are several large marine heat waves, with one of the largest departures still across the North Pacific.

Another season of tracking freezing degree days in the high #Arctic has ended. This is a simple measure of relative cold integrated with time. This past year was quite anomalous again, consistent with a rapidly warming Arctic system.

Also news - 2026 observed the 3rd lowest annual maximum #Antarctic sea ice extent on record. This was reached earlier in the year than average.

Since the maximum, ice extent has rapidly tumbled to close to record low levels for the date!

This is pretty wild... the average global sea surface temperature (outside of the polar regions) is still above 70°F (21.1°C) through the end of September. This is significantly above the prior record.

We'll cover this in our October climate briefing: https://climatecentral-org.zoom.us/webinar/register/5817787808929/WN_xagcAeAWQqqSZ04Z-knJRA

Despite the persistent Beaufort Sea ice earlier in the summer, there were some pretty large departures by September. This pattern of negative anomalies is very consistent with years since the mid-2000s.

Wednesday El Niño update - The explanation for why sea surface temperatures are still at record high levels in the Niño 3.4 region is because of both climate change plus El Niño.

Far-reaching El Niño-Southern Oscillation (ENSO) teleconnections are more dependent on temperature gradients, and relative sea surface temperatures are actually more in line with other strong events.

The extent of global sea ice has been the 3rd lowest on record for the date (satellite-era) over the last couple of weeks. This was especially due to unusually low ice cover in the Antarctic.
