The GISS V4 land/ocean temperature anomaly was 1.21°C in January, up from 1.35°C in December. This fall is similar to the 0.165°C fall reported for TempLS.
As with TempLS, January was still by a small margin the warmest January in the record - next was 1.18°C in 2016.
As usual here, I will compare the GISS and earlier TempLS plots below the jump.
