Just for background in case of any questions, here's the GISS press release below. GISS has 2007 higher in rank than we do, just like 2005 - which they have top, instead of 1998. A quick look at their 2007 spatial map indicates why - their extrapolation of the warm Arctic coastal data across the Arctic Ocean. Despite the differences in base periods, the maps (our Fig 3a and their 1b) are quite similar over most of the world. Their extrapolation also makes Antarctica much warmer than it probably was.
