The December 2019 temperature was up by 0.12C from November at 1.01C relative to 1961-1990. This completes the annual global average temperature for 2019 making it the second warmest year at 0.86C. This is just 0.015C cooler than 2016. All these values are calculated using GHCN-V4 and HadSST3 and spherical triangulation.
Here is the temperature distribution for December
Notice in particular the warmer than average temperatures across Australia, parts of the US and Northern Europe plus the ocean hot spot west of New Zealand.
Here are the final trend results for 2019
and the Annual trends showing 2019 slightly cooler than 2016.
So 2019 ended with a warm December and Australia suffering terrible bush fires. I will be there in 3 weeks time and was planning to first visit the Blue Mountains.
