Satellite-Inferred Global Temperature Anomaly Higher Again In March

Eleven days late getting to this, in part due to pain aversion* induced by getting so close to our prop-bet target, only to have victory snatched away with just 1/100 of a degree C to go. 

From the keeper of the record at the University of Alabama - Huntsville, Dr. Roy Spencer, April 3:

UAH v6.1 Global Temperature Update for March, 2025: +0.58 deg. C 

The Version 6.1 global average lower tropospheric temperature (LT) anomaly for March, 2025 was +0.58 deg. C departure from the 1991-2020 mean, up from the February, 2025 anomaly of +0.50 deg. C.

The Version 6.1 global area-averaged linear temperature trend (January 1979 through March 2025) remains at +0.15 deg/ C/decade (+0.22 C/decade over land, +0.13 C/decade over oceans).

The following table lists various regional Version 6.1 LT departures from the 30-year (1991-2020) average for the last 15 months (record highs are in red)....

March 4, 2025 - Satellite-Inferred Global Temperature Anomaly Reversed Downtrend in February

Last month's temperature was within 1/100 of a degree C of our prop bet target and an unfamiliar flash of brilliance, easily suppressed, came to mind:

0.01°C away from the target.

If I was smart I'd just declare victory today, a full 15 months ahead of schedule and let the bet melt into the noise of the internet but as they say at the better science schools: Homie don't roll that way.

And now the decline has turned higher....
