The global average lower tropospheric temperature (LT) anomaly of version 6.0 for April 2021 was -0.05 degrees. C, after the value of -0.01 degrees from March 2021. C.

REMEMBER: We changed the 30-year averaging period from which we calculate anomalies from 1991-2010 to 1991-2020. This change does not affect temperature trends.

The effects of the global cooling of the current La Nina are now fully realized at global tropospheric temperatures.

The linear warming trend since January 1979 remains at +0.14 ° C / decade (+0.12 ° C / decade over the globally averaged oceans and +0.18 C / decade over globally averaged land).

Various regional LT deviations from the 30-year average (1991-2020) over the last 16 months are:
