Dr. William Sprigg is research professor of atmospheric sciences at the University of Arizona and was head of the International Technical Review Panel for IPCC’s first report. The distinguished doctor slams the conduct of some of his global warming colleagues and accuses fellow IPCC scientists of “too much hubris.” He also told the Arizona conference, “climate data has been withheld and manipulated ”and that it is clear that “someone took out information.”

Here is a newly released video from the Heartland Institute, of Sprigg’s presentation to a packed audience of scientists at the 13th Annual Energy and Environment Conference, Phoenix, Arizona on Tuesday February 2, 2010

Although a non-skeptic, the esteemed former IPCC man is now on the campaign trail to restore the credibility of his profession. Still adamant that human carbon dioxide emissions are impacting the climate, the professor is deeply disturbed by what he has read in the leaked Climategate emails and calls for more respect to be shown to scientists who hold sceptical viewpoints.

Sprigg bemoans the fact that the IPCC has scorned any further reviews, and is unimpressed with the computer forecasts of climatologists calling their scenarios “tentative models.”

All scientists should applaud Sprigg for a clear show of honest principles so wanting of late at the IPCC. We commend Professor Sprigg’s honorable example and we hope that this leads to open sharing of data that needs to be placed in the public domain.
