+0.20 levels C – watts with that?

Reposted from Dr. Roy Spencer’s blog

August 2, 2021 by Roy W. Spencer, Ph. D.

The global average lower tropospheric temperature (LT) anomaly of version 6.0 for July 2021 was +0.20 degrees. C, compared to the value from June 2021 of -0.01 degrees. C.

REMEMBER: We have changed the 30-year averaging period from which we calculate anomalies from the old period 1981-2010 to 1991-2020. This change does not affect temperature trends.

The linear warming trend since January 1979 has remained at +0.14 ° C / decade (+0.12 ° C / decade over the global oceans and +0.18 ° C / decade above the global land average).

Various regional LT deviations from the 30-year (1991-2020) average of the last 19 months are:
