“UAH Global Temperature anomaly published, 1998 still warmest year in the UAH satellite record“. Dr. Roy Spencer declares 2010 and 1998 to be a tie for “warmest year” in the UAH satellite record. So stop talking about the GISS surface temperature records.

Also, Dr. Spencer changes his comparison “base period”:

we have just switched from a 20 year base period (1979 – 1998) to a more traditional 30 year base period (1981-2010) like that NOAA uses for climate “normals”.

An entirely accidental effect will be that “because the most recent decade averaged somewhat warmer than the previous two decades, the anomaly values will be about 0.1 deg. C lower than they used to be.”
