From Clive Best:
My preferred method for calculating the global average temperature anomaly for HADCRUT4.6 is by triangulating the measurements over the surface of a sphere. This gives almost identical results to those of Cowtan & Way but is a far simpler and faster method. Here is my update for July 2018.
Here is a the detail for the Northern Hemisphere
Finally here is the Southern Hemisphere (their winter) which shows cooler than normal temperatures over the tip of South America.
I do wish that graphical and image presentations using anomalies would include the actual value of the perceived normal. (ie: what is the actual temperature of the 0.0 anomaly?). Is it now a standard temperature across all presentations? Or what?
