GISS April global temperature down by 0.2°C from March.

The GISS V4 land/ocean temperature anomaly was 1.00°C in April 2023, down from 1.23°C in March. This fall is a little more than the 0.158°C fall reported for TempLS.

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

April global surface TempLS down 0.158°C from March.

The TempLS FEM anomaly (1961-90 base) was 0.859°C in April, down from 1.017°C in March. It was still the fourth warmest April in the record, and the second warmest month since October 2021. The NCEP/NCAR reanalysis base index fell even more by 0.332°C.

Almost all the world was warm, with cold spots just in Alaska, central Siberia down to India, and some of mid west USA. Nowhere was very warm, except a patch in Antarctica.

Here is the temperature map, using now the FEM-based map of anomalies.

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.
