Mann Made Science Faulted

Lawrence Solomon: Under oath, North faults Mann too
By Lawrence SolomonOf all the scientists who have come to Michael Mann’s defence, none have more impressive credentials than those of Gerald North, a former Head of the Department of Atmospheric Sciences at Texas A&M University. North, a physicist, has not only spent decades addressing the dangers of climate change, he has done so through his work in climate models and his knowledge of statistics, a suite of qualifications that make him particularly well qualified to comment on Michael Mann’s statistics-based work. Because of his background, and because Mann’s hockey-stick graph had become a source of great controversy, the National Academy of Sciences (NAS) asked North to chair a panel to investigate the statistical validity of the hockey stick graph. The NAS, like most national academies, backs the man-made global warming thesis.
…
But the story that North and other panel members relayed less than one month later, when they were required to testify under oath, showed the NAS report to be the opposite of what most had assumed. The setting was now not a press conference but formal hearings before the Energy and Commerce Committee of the U.S. House of Representatives. Because Mann had refused to provide other researchers with the computer code necessary to verify his work, because the credibility of the science surrounding the hockey stick had become a cause célèbre, and because federal government funds had financed the hockey stick study, the Energy and Commerce committee the previous summer had decided to hold hearings into the matter.
