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

June Global Temperature falls 0.04C

The global averaged surface temperature for June 2019 was 0.62C using my spherical triangulation method merging GHCNV3 with HadSST3. This is a further drop of 0.04C from May 2018. The discrepancy with GHCNV4 is however growing. V4C calculated in exactly … 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
