Japanese Analysis of US Gov Data Indicates Warming … Stopped?

This from Anthony Watts, friend of PJM and occasional contributor:
Please have a look at this, and thank the Japanese.
BTW, in case it isn’t obvious, this find throws the “hottest ever” claims of NOAA/NCDC/NASA into serious question, since the temperature peaks of the last decade are well below that of the NOAA/NASA/Met office data set.
What are they going to say, that Japanese scientists “did it wrong” when they cite it in their own publications?
What we really need to see is the unadjusted CLIMAT data reports plotted prior to 2000. I’m betting NCDC will be loathe to do that, for obvious reasons.
Read the whole thing, but basically the difference between warming in US models and no-warming in the Japanese models comed from the systematic adjustments applied.
Just to be clear here, these data are not the result of a prospective, predictive sort of climate model; however, the way the raw data is combined into a curve and the adjustments applied are the result of a statistical model.
