GISTEMP assumes that the Arctic is warming as fast as the stations around the Arctic, while HadCRUT and NCDC assume the Arctic is warming as fast as the global mean.

GISTemp will most likely show «statistically significant» global warming since October 1998.

Posts at RealClimate (here) and at SkepticalScience (here) looked on the paper as the second coming of... errr... Hansen's GISTEMP maybe, saying Cowtan and Way (2013) proved the UKMO HADCRUT4 data underreports by half the warming of global surface temperatures since 1997.
