I just found this little chart (I really like charts and graphs) on the NCDC site. It shows global land/ocean temps since 1950, so obviously a relatively short record. BUT, what’s most interesting is how this past year’s La Nina had little effect on global temps, or at least less effect than in the past. In fact, 2011 was the warmest La Nina year during that period of time. Interesting eh? Of course we’re talking about all of 1/2 degree difference, but interesting nonetheless.
