Another dataset confirms that last month was the warmest October on record in the #Arctic. The previous record was 2024. This is already a month with a very large increasing temperature trend (i.e., Arctic amplification). Not good.

Trends in November #Arctic sea ice thickness over the last four decades. Unsurprisingly, ice is thinning across the entire Arctic Ocean.

My #Arctic temperature graphics have just been updated for October 2025. New records were reached in my High Arctic and Atlantic Arctic regional sectors and close as well around the Greenland sector.

Here's a look at the extent of the "warmth" across the #Arctic in October. This map uses my normal anomaly scaling for each month, but it clearly doesn't work for something this extreme.
