November Global Temperatures Were 3rd Warmest On Record

November, 2025 was the world's third warmest on
record. As usual, it was hard to find the few
cooler than normal areas (in blue)

 Continuing a trend that started half a year ago, the world had its third warmest November on record, according to NOAA's National Centers for Environmental Information. 

 This was the sixth month in a row that the world had a third warmest month, in each case just behind 2023 and 2024. 

The warmest places relative to normal were in the Arctic, most of the Northern Hemisphere land areas, eastern Antarctica, southern Africa and eastern Europe. 

As always in this age of climate change, November cool spots were hard to find. Those few relatively chilly areas included northeastern Russia, parts of the central an eastern tropical Pacific Ocean, bits and pieces of Australia, and a persistent cold blob south of Greenland. 

We do the following every month to show how entrenched climate change has become: If you under age 49 you have never seen a month that globally was even a tiny bit cooler than the 20th century average. 

Depending upon how the December figures come out, 2025 will either be the third hottest year on record, to it will tie with 2023 as second hottest. Last year was the globe's hottest since people starting keeping reliable records in the 1850. 

The warm November contributed to a year that's messing with a key climate goal the United Nations set nearly a decade ago. 

The UN in 2016 adopted a legally binding compact -- the Paris Agreement -- that aims to keep global temperatures no more than 1.5 degrees Celsius above the 20th century agreement.

As Yale Climate Connections reports, it looks the warmth of this year will mean the three-year average temperature, 2023 -2025 will end up warmer 1.5 degree Celsius. 

Does that mean the Paris Agreement is violated? Depends on who you ask, because nobody really defined the parameter of what 1.5 degrees mean in the real world. But my opinion, yes. 

The World Meteorological Organization's 2024 State of the Global Climate Report states that they've convened a panel of experts to determine how exceeding the 1.5 degrees would be defined and tracked. 

We probably will have a few more years that average less than 1.5 degrees below the 20th century average, but they will become  increasingly rare.

Elsewhere, climatologists also like to keep an eye on Arctic and Antarctic sea ice, as those are a key indicator of the planet's climate health. 

The news from the top and bottom of the world was not good. Arctic sea ice in November was the second lowest on record for this time of year. Once we got into December, Arctic sea ice ran neck and neck with 2016 as the least on record. 

Antarctica sea ice was the fourth lowest on record, at least since satellites started keeping track of it in 1978. Only 2016, 2023 and 2024 had less ice way down under. 

UNITED STATES

November in the Lower 48 of the United States was the fourth warmest on record. 

November in the Lower 48 of the U.S was the
fourth warmest on record States in darkest 
red had their warmest on record November. 

The warmth was especially strong in the western United States. Idaho, Nevada, Oregon, Texas and Utah had their hottest November on record. Utah shattered the record by more than a degree, which is a really impressive

New Mexico had its second warmest November. Colorado, Oklahoma and Wyoming each had their third warmest November. 

When the western part of the nation is warm, more often than not, the eastern part is cool. That was true in November, 2025. But the eastern chill was not nearly as extreme as the western balminess. 

The state-by-state rankings go back 131 years. The "coldest" state in the rankings, was New York, which had its 67th warmest, (or 64th coolest) November on record. Here in Vermont, we had our 62nd warmest November out of the past 131. So pretty much in the middle of the pack.  

The Lower 48 had its 26th driest November out of the past 131 years. Dry weather was well distributed around the nation, but the southeast corner of the U.S. was especially arid. South Carolina had its second driest November, and in Florida, it was third driest. 

Only three states - Arizona, California and South Dakota were noticeably wetter than average, but were not nearly soggy enough to threaten any records. 

Meteorological autumn- September 1 through November 30, was the third warmest on record in the Lower 48. This autumn, all states in the Lower 48 except the Carolinas were at least 1 degree warmer than the 20th century average. 

Seven states - Idaho, Nevada, New Mexico, Oregon, Texas, Utah and Washington - had their warmest autumn on record.  Remarkably, everyone west of the Mississippi Rivet had one of their top 10 warmest autumn on record. All those states except California had one of their top five hottest falls. (California only had its tenth warmest. 

For the record, Vermont overall had its 23rd warmest autumn out of the past 131 years.
