What I get from this is that there is neither the accuracy nor the precision in the output of the models; so they homogenize the real world data into making the anomalies match the simulations. They disguise the meaningless of there system with fancy words to try and make it seem that they really know what they are doing.
The problem they have is Mother nature doesn’t give a hoot about the system, GCM’s theories and fancy words so they are left with models that say its supposed to be getting hotter and the real world that is not. The only good that can possibly come of this travesty is that sometime in the near future we will decouple science and engineering from politics!
Sorry for the rant but I’m of the generation that went to the moon and back using slide rules!
We recently presented and discussed modeled and observed global surface temperatures in absolute terms. See the post On the Elusive Absolute Global Mean Surface Temperature – A Model-Data Comparison. The WattsUpWithThat cross post is here. Yesterday, Willis Eschenbach at WUWT furnished EXCEL spreadsheets that included the outputs of climate model simulations of global surface temperatures in absolute terms. See Willis’s post CMIP5 Model Temperature Results in Excel.
Hot on the heels of those two posts comes a discussion at RealClimate of modeled absolute global surface temperatures, authored by Gavin Schmidt, the head of the Goddard Institute of Space Studies (GISS). Gavin’s post is Absolute temperatures and relative anomalies. Please read it in its entirety. I believe you’ll find it interesting. (Thanks, Gavin.)
