UAH Global Temperature Update for March, 2023: +0.20 deg. C

April 3rd, 2023 by Roy W. Spencer, Ph. D.

The Version 6 global average lower tropospheric temperature (LT) anomaly for March 2023 was +0.20 deg. C departure from the 1991-2020 mean. This is up from the February 2023 anomaly of +0.08 deg. C.

The linear warming trend since January, 1979 remains at +0.13 C/decade (+0.11 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 15 months are:
