Global Temperature Anomaly updated for June 2020

The global temperature for June 2020 was 0.79C based on my spherical triangulation method. Here are the monthly results based on the latest GHCN-V4 and HadSST3 data as compared to those from original V3C station data.

The temperature peaked in February at 1.1C and has since been falling. The Northern Hemisphere also shows a notable hotspot across Siberia as shown below.

Half way through 2020 we can also calculate the annual temperature anomaly. This gives an average value for the first 6 months of 0.98C. For comparison I also show the results based on HadCRUT4.6 up to 2019. CRUTEM4 station data is not yet available for June 2020.

2020 looks set to become the warmest year to date, although the monthly trend still appears to be dropping.

    There was an upward bump last year, due mostly to a spike in NH ssts. Unless there is a repeat of that in July and August, or an unlikely El Nino apprearance, I don’t see 2020 beating 2019. But we call her Mother Nature because she often surprises.

      Interesting. Ocean temperatures surely are the main driver. However the change from V3 to V4 has also increased slightly the global temperature. HadCRUT4 is essentially equivalent to V3 but it is not available yet for June.
