The UAH lower troposphere temperature trends are turning south as the weaker Solar Cycle 25 continues into the Modern Solar Minimum.
The full UAH Global Temperature Report, along with the LT global gridpoint anomaly image for February, 2021 should be available within the next few days here.
The global and regional monthly anomalies for the various atmospheric layers should be available in the next few days at the following locations:

The high frequency solar minimum between Solar Cycle 24 and 25 happened in December 2019, when the 13-month smoothed sunspot number fell to 1.8. Solar Cycle 25 with peak sunspot activity expected in July 2025.
Solar Cycle 24 had the 4th-smallest intensity since regular record keeping began with Solar Cycle 1 in 1755. It was also the weakest cycle in 100 years. Solar maximum occurred in April 2014 with sunspots peaking at 114 for the solar cycle, well below average, which is 179.
Solar Cycle 25. Solar Cycle 25 is forecast to be a fairly weak cycle, the same strength as cycle 24. Solar maximum is expected in July 2025, with a peak of 115 sunspots.
