Record high temperatures are currently being set across the northernmost portions of the #Arctic. In fact, it is effectively ice-free on the Atlantic side of the Arctic all the way up to about 85°N latitude! This includes record low sea ice around Svalbard.

Happy October 1st and start to spooky season (though for me, that begins in early September 😅).
It's my favorite time of year, so I thought I would kick it off with something pretty scary!

Sadly impressive.
It's been extremely warm (again) over global land areas so far this year. Here's a comparison against every other average January-August period since at least 1850...

All latitude bands were warmer than average over the last 3 months. This was particularly notable across the Antarctic around the South Pole (austral winter).
Plot shows zonal-mean temperature anomalies, where latitude = y-axis (not scaled by distance). GISTEMPv4 data using their 1951-1980 baseline

To complement my plot of yearly temperatures, I added a new graph showing changes in annual precipitation averaged across the contiguous United States (CONUS) from 1895 through 2024.
I will update this visualization each year at zacklabe.com/climate-chan.... Data is from NOAA NClimGrid.

Yes, Antarctic sea-ice extent has been crashing, with the 3-year running average recently setting a new record low, down nearly 20% from its 2016 peak and more than 10% from its long-term average.
The 3-year running average smoothes out short-term anomalies and tells the story:

April data for "total column precipitable water" just came in from ECMWF, and, you guessed it, yet another record high for the 36-month running average, while April 2025 was the third highest April since 1940.
Information overload summary: a hard rain's a-gonna fall.

NOAA Regional Climate Centers’ contracts are lapsing, and they are shutting down. The administration wants Congress to eliminate the NOAA office of Oceanic and Atmospheric Research, which supports thousands of employees and university research. It’s up to you to advocate against these cuts!
