It was presented last May to the Natural Resources Committee of the U.S. House of Representatives by University of Alabama's John Christy.
It isn't the usual comparison between surface temperatures and climate forecasts. Instead, it shows the forecast and observed temperature of the middle troposphere. The troposphere is where the world's weather action is, from the surface on up to around 45,000 feet (depending upon latitude and season).
The red line is the average mid-tropospheric temperature in the 102 climate models used by the UN in its latest compendium of published scientific opinions on climate change. It's smoothed out by using running five-year averages, not a bad way to get rid of the year-to-year noise in annual data.
The green squares are the average of the two satellite-sensed temperature histories for the mid-troposphere. The blue dots are a completely independent measure of that temperature, which is the average of the four commonly-cited analyses of global weather balloon data. These are taken twice a day with extremely accurate sensors. Both of these datasets were subject to the same smoothing as the model predictions.
