The tropospheric temperature (LT) anomaly is -0.04 degrees below the Edition 6 global average for January 2023. C comes from the meaning 1991-2020. This is down from the December 2022 anomaly of +0.05 degrees. C.
The linear warming trend since January 1979 is now +0.13 C/decade (+0.11 C/decade for the global average oceans and +0.18 C/decade). for the global land average).
The regionally different LT departures from the 30-year (1991-2020) average over the past 13 months are:
