‘Official’ climate science response: claim satellite data is not reliable, and play shoot-the-messenger. Predictable, as the results obviously don’t fit theories of man-made warming.

Global warming has not accelerated temperature rise in the bulk atmosphere in more than two decades, according to a new study funded by the Department of Energy.

University of Alabama-Huntsville climate scientists John Christy and Richard McNider found that by removing the climate effects of volcanic eruptions early on in the satellite temperature record showed virtually no change in the rate of warming since the early 1990s.

“We indicated 23 years ago — in our 1994 Nature article — that climate models had the atmosphere’s sensitivity to CO2 much too high,” Christy said in a statement. “This recent paper bolsters that conclusion.”

In order to measure Earth’s radiation balance, accurate measurements of both incoming and outgoing radiation have to be made. NASA has been testing a new prototype satellite to measure outgoing radiation from Earth. Up until now, the error on this measurement is estimated to be around +/- 5Wm^2, which means any ‘global warming’ signal is lost in the error margin. This has meant scientists have had to rely on models for estimates.

Tony Heller, AKA Steve Goddard, has this new video up on youtube. It raises important questions about the way the global temperature record has changed over time.
