The Version 6.0 global average lower tropospheric temperature (LT) anomaly for May, 2022 was +0.17 deg. C, down from the April, 2022 value of +0.26 deg. C.
The linear warming trend since January, 1979 still stands at +0.13 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).
Various regional LT departures from the 30-year (1991-2020) average for the last 17 months are:

The young trees in our garden are all taking a battering this summer because it has been so cold with the wind chill factor. We even had frost a few days ago. I am still waiting for the warm weather that the weather bureau promised a couple of months ago.
Here it is not one solar cycle that is important, but a clear downward trend of the solar magnetic field. This is not a matter of 11 years, but at least 22, because that is the solar magnetic cycle.

Shouldn’t we screen out the effects of La Nina and El Nino to get a more accurate picture of temperature change? Also, doesn’t the temperature graph depict two periods of temperature change? It would seem the period shown is actually from two temperature change periods. One from about 1975 until about 2005 (or the highest temperature thereabout) and one from about 2005 until the present. This would better show the pause-warming pattern seemingly established in the longer temperature record since the 1880’s.
Unless you’re trying to control for ENSO it is best to leave the data as reported by UAH. Likewise no one would try to screen out the effects of solar, volcanic, tropical cyclones, snow/ice cover, or any of the other of the multitude of factors that modulate the UAH TLT temperature unless they are specifically wanting to isolate those factors.
I should have been clear that I meant in discussion of the graph, not in presentation of the graph.
I was speaking in regards to general discussions.
The point I’m making is that the discussion masked the substantial reduction in the slope of the warming curve at about 2004 where a pause period would begin if the established pattern of equal length periods of pause and warming was continuing.
