This decoupling is quite apparent. Here are the sea surface temp anomalies from 1940 to present, with 2023, 2024, and 2025 highlighted.

I phrased my question incorrectly. What I meant to say was that in late December, 2023 had the highest sea surface temperatures of all years in the data set. This is from the Copernicus site, where I could easily highlight the years.

I was looking at the global sea surface temperatures from the climatereanalyzer.org The most global data I found was from 60°S to 60°N. If I'm reading the chart correctly, 2023 had the highest temperatures ever recorded in the data set. Where is the error? Thanks.

Daily data fix! 21 Jan global mean surface air temp was 0.80°C over the 1991-2020 average. With the offset of +0.96°C, that makes 21 Jan 2025 1.76°C over pre-industrial.

Daily data fix! From pulse.climate.copernicus.eu The global surface mean air temp for 19 Jan was 0.88°C above the 1991-2020 average. Adding the offset of 0.96°C, 19 Jan 2025 is 1.84°C above pre-industrial.

Daily data fix! (Copernicus back up, my earlier post had an error). 18 Jan. global mean surface temp was 0.87°C above the 1991-2020 average. Adding the offset of 0.96°C, we find that 18 Jan 2025 is 1.83°C above pre-industrial. Not good.

Anyone like me, who can't get enough weather data? Go to climatereanalyzer.org and play around. Here is the NAM model (North American Mesoscale) at a resolution of 3km. This particular model is computed every 6 hours and gives temperature forecasts hourly up to 60 hours in the future.

because the normals are different (1981-2010 vs. 1991-2020), we see that the global mean surface air temp (black line) is forecast to be ~0.7°C over 1991-2020 as that the normal used for Copernicus data. With the offset, the next 7 days are forecast to be ~1.65°-1.7°C over pre-industrial.

Daily data fix! For 13 Jan, the global surface mean temp was 0.71°C above the 1991-2020 average. The offset for 13 Jan is 0.96°C, so 13 Jan was 1.67°C above pre-industrial.

Daily Data fix! Copernicus had a problem with their data for almost a week, but its all fixed now. 10 Jan had a global mean surface air temp 0.80°C above the 1991-2020 average. With the +0.96°C offset, 10 Jan was 1.76°C above pre-industrial. The first 10 days of Jan are ~1.71°C > pre-industrial.

Yeah I know, I'm here to spoil the party. While the "hole" may be the lowest in record with a hole being defined as <220 Dobson Units (measurement of how much UV reaches the ground), the severity of the hole was much worse 30 years ago, with the minimum being 88 DU We are nowhere that close today

This is the 7am balloon sounding in Nashville, TN. The columns are pressure in mb, height in meters, temp in °C, and dew point in °C. You can see it is below freezing at the surface, but above freezing at ~1000 meters, This "warm nose" of air may change the snow to rain or sleet later.
