July global temperature anomaly unchanged from June at 0.79C

Posted on August 14, 2020 by Clive Best

My 3D calculation of the global temperature anomaly for July 2020 using GHCN-V4 and HadSST3 is 0.79C (baseline 1961-1990), the same value as for June. However the spatial distribution has changed significantly. Here are the monthly trends and the annual … Continue reading →

GHCN V4 warming (updated 2/8)

Posted on July 31, 2019 by Clive Best

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

Posted on July 27, 2019 by Clive Best

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 →
