The contrasting directions are a result of the fading influence of polar warming. Basically, NOAA was down in November because it included the Siberian cold, but not the complementary Arctic warmth, while GISS was high then. The split in
TempLS variants was similar, and BEST also dropped by about 0.06, similar to TempLS mesh. The drop in GISS was a little larger than I expected. HADCRUT 4 rose by about 0.07°C, under the same influence as NOAA and TempLS grid.
As noted in my
earlier post today, GISS, NOAA and HADCRUT 4 did set records in 2016, GISS by a larger margin.
I'll show the regular GISS plot and TempLS comparison below the fold
Here is the GISS map for the month

Ah, yes, thanks, fixed.
DeleteIt was a busy night down under. It seems Sou and I were both tapping away at about 4am - well, I was. Sou is much faster. This post came much later, so I really have no excuse.
