The Version 6 global average lower tropospheric temperature (LT) anomaly for November, 2023 was +0.91 deg. C departure from the 1991-2020 mean, statistically unchanged from the October, 2023 anomaly of +0.93 deg. C.
The linear warming trend since January, 1979 still stands at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.19 C/decade over global-averaged land).
Various regional LT departures from the 30-year (1991-2020) average for the last 23 months are:
