UAH Satellite-Inferred Global Temperature Anomaly: Down Slightly For December After Record High During 2024

Our proposition bet has the UAH figure falling from +0.95°C the day we announced the bet, May 2, 2024 (three days later the April figure was announced, +1.05°C, not very good timing on the part of yours truly) to +0.45°C by the termination date:

Here's a prop bet for you. By May 15, 2026 we will see the satellite-measured -inferred global lower atmospheric temperature anomaly decline by at least 1/2 degree C.

The two keepers of the satellite record are Remote Sensing Systems in Santa Rosa CA and the University of Alabama-Huntsville.

Here's the temperature graph from UAH:....

And from Dr. Roy Spencer at the University of Alabama-Huntsville, January 3, 2025:

UAH v6.1 Global Temperature Update for December, 2024: +0.62 deg. C

2024 Sets New Record for Warmest Year In Satellite Era (Since 1979)

The Version 6.1 global average lower tropospheric temperature (LT) anomaly for December, 2024 was +0.62 deg. C departure from the 1991-2020 mean, down slightly from the November, 2024 anomaly of +0.64 deg.

The Version 6.1 global area-averaged temperature trend (January 1979 through December 2024) remains at +0.15 deg/ C/decade (+0.22 C/decade over land, +0.13 C/decade over oceans).

As seen in the following ranking of the years from warmest to coolest, 2024 was by far the warmest in the 46-year satellite record averaging 0.77 deg. C above the 30-year mean, while the 2nd warmest year (2023) was +0.43 deg. C above the 30-year mean. [Note: These yearly average anomalies weight the individual monthly anomalies by the number of days in each month.]....
