The global mean lower tropospheric temperature (LT) anomaly for the August 2024 version 6 is +0.88 degrees. C deviates from the 1991-2020 average and is slightly above the July 2024 anomaly of +0.85 degrees. C.
This month's sustained global average temperatures are (unusually) caused by the Southern Hemisphere. Of the 27 regions we regularly monitor, five had record-warm (or near-record) monthly abnormally high temperatures in August, all contributed by the Southern Hemisphere:
Global land: +1.35 degrees C
Southern Hemisphere land: +1.87 degrees. C
Temperate lands in the Southern Hemisphere: +2.23 degrees. C
Antarctica: +3.31°C (2nd place, previous record was +3.37°C, August 1996)
Australia: +1.80 degrees C.
The linear warming trend since January 1979 is currently +0.16 C/decade (global mean ocean +0.14 C/decade, global mean land +0.21 C/decade).
The following table lists the deviation of regional LT from the 30-year (1991-2020) average over the past 20 months (historical highs are shown in red):
