Ever wonder why everyone produces anomalies instead of absolute temperatures? You’ll have to read the references to get the whole story. Worth the effort.
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.)
