The Version 6 global average lower tropospheric temperature (LT) anomaly for August, 2024 was +0.88 deg. C departure from the 1991-2020 mean, up slightly from the July, 2024 anomaly of +0.85 deg. C.
Persistent global-averaged warmth was (unusually) contributed to this month by the Southern Hemisphere. Of the 27 regions we routinely monitor, 5 of them set record-warm (or near-record) high monthly temperature anomalies in August, all due to contributions from the Southern Hemisphere:
Global land: +1.35 deg. C
Southern Hemisphere land: +1.87 deg. C
Southern Hemisphere extratropical land: +2.23 deg. C
Antarctica: +3.31 deg. C (2nd place, previous record was +3.37 deg. C, Aug. 1996)
Australia: +1.80 deg. C.
The linear warming trend since January, 1979 now stands at +0.16 C/decade (+0.14 C/decade over the global-averaged oceans, and +0.21 C/decade over global-averaged land).
The following table lists various regional LT departures from the 30-year (1991-2020) average for the last 20 months (record highs are in red):

I have been saying this now for as long as Scientist kept claiming, that man and his input is the cause of Global warning! This claim is totally untrue and can be proven beyond a shadow of doubt! i.e. Temperatures on the earth surface has been changing for millions of years now, which is not caused by man and his automobiles and other alleged contributors of Co-2 contributions that man has caused to the earth! For the record, Therefore, all the Governments trillions of dollars of regulations they implement upon the earth in efforts to control CO/2 is totally wasted!
