CRUTEM4 is cooler than GHCN-V4

The October 2019 global temperature anomaly that I calculate based on the latest CRUTEM4 station data is 0.15C cooler than that using GHCN-V4 (0.79C asĀ  compared to 0.96C). The temperature series are calculated in exactly the same way and both … Continue reading

October temperatures rise 0.18C

October saw a large increase of 0.18C in the global average temperature (anomaly) since September. These results use a spherical triangulation of land (GHCN-V4) and ocean (HadSST3) temperature data with a baseline of 1961-1990. The methodology is described in this … Continue reading

September global temperature falls 0.04C

These results use a spherical triangulation of land (GHCN) and ocean (HadSST3) temperature data with a baseline of 1961-1990. Since August I have been forced to update to GHCN-V4 land temperatures since GHCN-V3 has been discontinued. September shows a small … Continue reading
