The UAH temperate dataset is maintained by former NASA scientist Dr Roy Spencer and his University of Alabama in Huntsville colleague, climate scientist Dr John Christy.
Since 1979, NOAA satellites have been carrying instruments which measure the natural microwave thermal emissions from oxygen in the atmosphere. The intensity of the signals these microwave radiometers measure at different microwave frequencies is directly proportional to the temperature of different, deep layers of the atmosphere. Every month, Dr Spencer and Dr Christy update global temperature datasets that represent the piecing together of the temperature data from a total of fifteen instruments flying on different satellites, know colloquially as ‘the UAH’.
The UAH is the best unbiased temperature dataset we truth-seekers have left. No, it should not be taken as gospel, but with the datasets custodians –Spencer and Christy– not bought and owned by the AGW Party, it will at least be free from agenda-driven manipulation.
EARTH’S AVERAGE TEMPERATURE DROPS TO 30-YEAR BASELINE
The Version 6.0 global average lower tropospheric temperature (LT) reading for February, 2022 has come in at 0.00 deg. C vs the multidecadal average, continuing the overall downward trend since 2016’s peak, now down approx. 0.71C deg. C since then.
In other words, it’s get harder and harder for the politicized ‘catastrophic global heating’ narrative to be maintained.
A continuation of this downward trend is probable over the coming months (with the odd bump along the way: climate is ‘cyclic’, after all) as low solar activity, La Nina, and the aftereffects of Hunga Tonga’s monstrous ‘mesospheric’ eruption continue to influence our climate.
According to the 15x NASA/NOAA AMSU satellites that measure every square inch of the lower troposphere (where us humans reside), planet Earth was actually warmer back in 1983:
Next are the various regional LT departures from the 30-year average for the last 13 months. Note that all regions logged a below average reading in Feb, 2022 (excluding NHEM at 0.01C), with AUST seeing the largest anomaly at -0.50C.

I’ll end it there for today; but not before taking a look at the late-season polar outbreaks threatening to descend into North America, Europe, and northern Asia/Russia simultaneously, outbreaks potentially tied to a SSW event developing above the Arctic.
