A gem from James - HADCRUT4 also says 2010 was the Best In Show for bad temperature news

Two months old, but hasn't had much play that I've seen.  The HADCRUT global surface temperature dataset, often preferred by climate denialists who play at such things, got an upgrade with more Arctic coverage.  Like other datasets, that Arctic climate amplification is enough to put HADCRUT4 2010 over the top of previous record holders 1998 and 2005.  I guess the denialists won't play with it as much now.

I have no idea if the difference for 2010 is statistically significant, but that's not an adverb that denialists care about.
