The Version 6.0 global average lower tropospheric temperature (LT) anomaly for March, 2021 has come in at -0.01 deg. C below the 30-year baseline, down from the February, 2021 value of +0.20 deg. C, and down substantially (approx. 0.6C deg. C) from where we were around a year ago.
A continuation of this downward plunge is highly probable over the coming months (with the odd bump along the way–climate is cyclic after all) as low solar activity and La Nina conditions persist.
According to the 15x NASA/NOAA AMSU satellites that measure every square inch of the lower troposphere (where us humans reside), planet Earth was actually warmer back in 1983:
REMINDER: We have changed the 30-year averaging period from which we compute anomalies to 1991-2020, from the old period 1981-2010. This change does not affect the temperature trends. [www.drroyspencer.com]
In addition, the global average oceanic tropospheric temperature anomaly is -0.07 deg. C–the lowest since November 2013. Also, the tropical (20N-20S) departure from average is -0.29 deg. C–the coolest since June of 2012. While Australia, at -0.79 deg. C, is the coolest reading since August 2014.
Bottom line, the Grand Solar Minimum is intensifying — and fast.
Sunspots (a great barometer for solar activity) have remained sparse in 2021, even at a time when the next the next solar cycle (25) should be firing-up.
The Solar Minimum of cycle 24 began bottoming-out way back in late-2017, and went on to develop into the deepest minimum of the past 100+ years — and it is still proving reluctant to release its grip:
