Roy Spencer has taken another cut at the data, and again the answer is about the same as what most thoughtful people have arrived at:  Perhaps half (or more) of past warming in the surface temperature record is likely spurious due to siting biases of surface measurement stations.

Again, there almost certainly is a warming trend since 1850, and some of that trend is probably due to manmade CO2, but sensitivities in most forecasts that get attention in the media are way too high.  A tenth of a degree C per decade over the next 100 years from manmade CO2 seems a reasonable planning number.

Spencer also looks at the global numbers here.
