MacLean’s magazine recently had a great article profiling Stephen McIntyre, a global warming realist who, along with Ross McKitrick, helped to break the so-called “smoking gun” of global warming, Michael Mann’s “hockey stick” graph.
Some excerpts:
The truth is that McIntyre, 62, little resembles the caricature of a wild-eyed climate-change “denier.” He is scrupulous about focusing his criticism on statistical procedures and disclosure practices. He is polite to, and about, climate scientists. He refuses to make grand categorical statements of the “Global warming is just commie horse puckey” type, preferring to remain agnostic, and he discourages such talk on his website, Climate Audit.
Spanish paleoclimatologist Eduardo Zorita of Germany’s GKSS Research Centre, who has clashed at times with both McIntyre and the climate-research elite, says that “in the realm of science, it doesn’t really matter by whom and why a study is criticized. It only counts whether or not the criticism is reasonably well-founded, is logical, and relevant for the final results.” [emphasis mine]
The world of mining [McIntyre worked for Noranda during its heyday as well as other smaller resource firms] is one in which everyone is constantly aware of how engineering results can be tampered with or misrepresented to rip off investors. And in 2003, when McIntyre first saw the hockey stick graph, it reminded him uncomfortably of some stock promoter’s over-optimistic revenue projection. McIntyre asked lead “hockey stick” author Michael Mann for the underlying data and was startled when Mann had trouble remembering where he had posted the files to the Internet. “That was when the penny dropped for me,” McIntyre says. “I had the sense that Mann was pulling together the data for the first time—that nobody had ever bothered to inquire independently into the hockey stick before.”
To McIntyre, a scientist’s data and code stand in the same relationship to a finished paper that drilling cores do to a mining company press release. “If you’re offering securities to the public,” McIntyre observed in a May 2008 talk at Ohio State University, “there are complicated and expensive processes of due diligence, involving audits of financial statements, independent engineering reports, opinions from securities lawyers and so on. There are laws requiring the disclosure of adverse results.” Peer review in scientific journals is good, he suggested, but it is limited and vulnerable to compromise. “There is far more independent due diligence on the smallest prospectus offering securities to the public than on a Nature article that might end up having a tremendous impact on policy.” [emphasis mine]
