I've been seeing a lot of people making the claim that global warming has "stalled" or stopped over the past few years (some say it stopped just last year). But I haven't seen any data yet.
So where is it? Which data shows a negative or absent trend over the past few years (be it ten, eight, five, or whatevs)? Is it GISS? HadCRU? NCDC? RSS? And also, perhaps more importantly, what level of significance can we assign to this trend?
Also, is there a physical basis for believing that this trend (if it is statistically significant) marks the end of 20th century warming?
