The Version 6 global average lower tropospheric temperature (LT) anomaly for June 2023 was +0.38 deg. C departure from the 1991-2020 mean. This is statistically unchanged from the May 2023 anomaly of +0.37 deg. C.

The linear warming trend since January, 1979 remains 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 18 months are:
