GISS April global temperature down by 0.07°C from March.

The GISS V4 land/ocean temperature anomaly was 1.32°C in April, down from 1.39°C in March. This fall is larger than the virtual tie reported here for TempLS.

As with TempLS, April was the warmest April in the record - next was 1.13°C in 2020.

As usual here, I will compare the GISS and earlier TempLS plots below the jump.

April global surface TempLS down 0.004°C from March, but still warmest April in record.

The TempLS FEM anomaly (1961-90 base) was 1.178°C in April, very slightly down from 1.182°C in March. It was still the warmest April in the record, ahead of 1.009°C in 2020. The NCEP/NCAR reanalysis base index fell by 0.077°C.



Here is the corresponding stacked graph, showing how much hotter recent months have been:


Here is the temperature map, using the FEM-based map of anomalies. Use the arrows to see different 2D projections.

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.
