Models are failing miserably at simulating the actual temperature rise in the earth’s lower atmosphere

See You Ought to Have a Look: Dr. John Christy’s House Testimony by Patrick J. Michaels and Paul C. "Chip" Knappenberger of Cato. Excerpts:

This concerns "Dr. John Christy’s written testimony before the U.S. House of Representatives Committee on Science, Space & Technology."

"The central element of his December testimony was that climate models are failing miserably at simulating the actual temperature rise in the earth’s lower atmosphere. The models produce about 2.5 times as much warming from human greenhouse gas emissions than has actually been observed by satellites and weather-balloons."

"Here are some of his zingers.

“It is a bold strategy in my view to actively promote the output of theoretical climate models while attacking the multiple lines of evidence from observations.”

“Investigations of us by congress and the media are spurred by the idea that anyone who disagrees with the climate establishment’s view of dangerous climate change must be on the payroll of scurrilous organizations or otherwise mentally deficient.”

“[T]hese models failed at the simple test of telling us ‘what’ has already happened, and thus would not be in a position to give us a confident answer to ‘what’ may happen in the future and ‘why.’”

“The information in this figure provides clear evidence that the models have a strong tendency to over-warm the atmosphere relative to actual observations.  On average the models warm the global atmosphere at a rate 2.5 times that of the real world.” 

“Because this result challenges the current theory of greenhouse warming in relatively straightforward fashion, there have been several well-funded attacks on those of us who build and use such datasets and on the datasets themselves.  As a climate scientist I’ve found myself, along with fellow like-minded colleagues, tossed into a world more closely associated with character assassination and misdirection, found in Washington politics for example, rather than objective, dispassionate discourse commonly assumed for the scientific endeavor.”"
