The GISS V4 land/ocean temperature anomaly was 0.86°C in January 2021, up from 1.10°C in December. TempLS however reported little change. Jim Hansen notes that it was much cooler than last year, being only the sixth warmest January in the record.
As usual here, I will compare the GISS and earlier TempLS plots below the jump.

January global surface TempLS same as December (cool).
The TempLS mesh anomaly (1961-90 base) was 0.62deg;C in January, also 0.62°C in December. That followed a large drop from 0.877°C in November. There was a small 0.0008°C rise in the NCEP/NCAR reanalysis base index.
The prominent feature was a cold band through Siberia, extending into central Asia. The corresponding parts of N America were very warm. Eastern Europe was warm, extending into N Africa. Antarctica was cold.
Here is the temperature map, using the LOESS-based map of anomalies.
As always, the 3D globe map gives better detail.
