GHCN V4 warming (updated 2/8)
In this post I investigate what has changed in global temperatures moving from GHCN-V3 to GHCN-V4, and in particular why V4 gives higher temperatures than V3 after 2000. Whenever a new temperature series is released it inevitably shows an increase … Continue reading
May global temperatures fall 0.16C
The global averaged surface temperature for May 2019 was 0.66C using my spherical triangulation method merging GHCNV3 with HadSST3. This is a significant drop of 0.16C from April 2018. The baseline used is always 1961-1990. I also applied the same … Continue reading
Changing temperature anomaly baselines
I wanted to check whether the choice of baseline can affect the calculation of global temperature anomalies from station data. Each temperature index (GISS, Berkeley, CRU) uses different normalisation periods for calculating weather station temperature anomalies. I was surprised to … Continue reading
