A U.S. map titled “Winter Warming Since 1970 (°F)” shows nearly all regions shaded in red, representing rising winter temperatures. The Upper Midwest and Northeast stand out as the fastest-warming areas, with average winter increases between +4°F and +6°F. Source: NOAA/NCEI Climate at a Glance.

Winter isn't what it used to be.

It's actually the fastest-warming season for much of the U.S.

Since just 1970, winters (December - February) have warmed in 98% of 244 U.S. cities analyzed by 3.9°F on average.

Do you wanna build a snowman with few of the details? 🧵

Demain jeudi, le seuil de chaleur (25°C) pourrait gagner jusqu'à la région Centre alors que l'effet de foehn devrait se maintenir près des Pyrénées où les 30°C pourraient à nouveau être approchés.

🌡️ L'avez-vous senti ? Une douceur remarquable touche le pays ce mercredi, avec des températures 5 à 8 °C au-dessus des normales.

📈 Attention, le vent de Sud se renforce : on attend 120 à 130 km/h, localement plus, dans la nuit de jeudi à vendredi.

Les températures observées cette après-midi sont tout simplement délirantes : les 30°C ont été approchés mi-novembre. Je répète au cas où : mi-novembre.

Boosté par un vent de foehn dans un air surchauffé par le changement climatique, on a atteint 29.8°C à Trois-Villes et 29,5°C à Aicirits

Breaking News!

It appears that the UN is now using the method Richard Betts proposed and I use to compute the "long-term" global temperature with respect to the Paris Agreement. Which means the planet will be breaking 1.5C in 2026 or 2027 at the latest.

Line graph time series of monthly mean surface temperature anomalies for the Antarctic region only. Every month is shown from 1940 to 2025. There is a long-term warming trend in all months of the year, but less obvious than the other regions.

Average temperature departures by month in the #Antarctic since the year 1940.

Green line graph time series of average sea surface temperature anomalies for each October from 1900 through 2025. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline.

The three-year running mean for the global surface temperature anomaly now exceeds 1.50°C over the pre-industrial baseline, as of November 8, 2025.

Are you there, COP 30? It's me, the Paris Agreement.

The past 3-years were on average +1.5°C, while the Relative Oceanic Niño Index was on average -0.19.

The Paris agreement is dead and buried.

What impact will this have on the negotiations in Belém at COP30?

Four polar stereographic maps showing Arctic near-surface air temperature anomalies for the month of November in 1985-1994, 1995-2004, 2005-2014, and 2015-2024. Most all areas are observing long-term warming, which is largest along the Eurasian coast.

Polar stereographic map of 2-m air temperature anomalies in the Antarctic for October 2025. Red shading is shown for warmer anomalies, and blue shading is shown for colder anomalies. There is a sharp gradient in temperature anomalies across the continent. Anomalies are calculated relative to a 1981-2010 baseline.

Here is a map view of the record high temperatures in October 2025 across the #Antarctic. Compare this blob of anomalies greater than 5°C with the Arctic from my earlier post. Yikes!

Green line graph time series of average sea surface temperature anomalies for each October from 1850 through 2025 for only the midlatitude region of the North Pacific Ocean. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline. 2025 is a record high.

Record high ocean temperatures continued across the North Pacific in October 2025, with recent warming really amplifying since the early 2000s.

This graph shows the average for a band across the midlatitudes for every October from 1854-2025 using

Polar stereographic map showing 2-m air temperature anomalies in October 2025 for the Arctic Circle with red shading for warmer anomalies and blue shading for colder anomalies. Most areas are warmer than average. The baseline is a 1981-2010 reference period using ERA5 data.

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.

Data from doi.org/10.24381/cds...

For those enjoying the race to the bottom, Arctic sea-ice extent is second lowest on record for the date, as of Nov. 8, 2025, just over 100k square kilometers above the record low, set in 2016.

<personal pronoun> <verb> f&%king <past participle>.

If our years ran from November to October, 2025 would be the second warmest year on record.

Probably in >100,000 years and potentially much longer.

Sea Surface Temperatures are now likely already higher than during the Eemian warm period, when global sea levels were ~7.5m higher!

Lowest global sea ice extent for November 6 on record.

Ignoring the tropics because of El Niño/La Niña, the past 12 months show record Sea Surface Temperatures for both hemispheres.

And the acceleration of warming over the Northern Hemisphere is painfully obvious:

Line graph time series of 2-m air temperature anomalies for the Arctic in every October from 1979 to 2025. There is a long-term warming trend, and 2025 is the warmest on record in this time series. Data is from ERA5 with a 1981-2010 climate baseline used for calculating the anomalies.

It's not every day that both poles set new monthly temperature records (see my earlier post). Last month also observed the warmest October on record for the #Arctic Circle. Not great!!
