The GISS V4 land/ocean temperature anomaly was 0.82°C in April 2022, down from 1.05°C in March. This drop is rather more than the 0.146°C fall reported for TempLS. While Templs returned to about February temperature, GISS was rather lower (Feb 0.89°C)
As usual here, I will compare the GISS and earlier TempLS plots below the jump.

April global surface TempLS down 0.15°C from March.
The TempLS mesh anomaly (1961-90 base) was 0.693°C in April, down from 0.843°C in March. That brings it back to the level of February, undoing the sudden rise to March. The NCEP/NCAR reanalysis base index fell by a very similar 0.163°C.
The most prominent feature is the coolness of N America (except SW) and E Europe. Central Asia was very warm, but unusually in recent times, the Arctic was not. The oceans were mostly warm except for the ENSO region.
Here is the temperature map, using the LOESS-based map of anomalies. As promised last month, you now have a choice of proections. Robinson shows by default, but if you click the buttons at the bottom, you can cycle through Mollweide and ordinary let/lon.
As always, the 3D globe map gives better detail. There are more graphs and a station map in the ongoing report which is updated daily.
