I’m in Sweden for a couple of days, threading my way between the “refugees” at the railway station. More on that anon. Nonetheless, a prudent man does not neglect book-plugging duties for long. So I see Lynne Cohen has a review of my new tome:
Michael Mann needs no introduction. He is the Yale-and-Berkley-educated physicist and mathematician, now a climatologist at Penn State University. He is also the inventor/creator/discoverer of the (in)famous hockey stick graph, what Steyn calls “the single most influential graph in climate science. It leapt from the pages of a scientific journal to the posters and slides of the transnational summits, to official government pamphlets selling the Kyoto Protocol, to a starring role on the big screen in an Oscar winning movie [An Inconvenient Truth], to the classrooms of every schoolhouse in the western world.” Also, a version of the hockey stick featured prominently in the influential United Nation’s 2001 Report of the Intergovernmental Panel on Climate Change.
The hockey stick graph purports to demonstrate that, for about 900 years — represented by the long handle lying flat — the world experienced almost no climate variation. Then, the blade of the stick shoots straight up for about 120 years, from the start of the industrial revolution… The only problem is, the hockey stick has been almost completely discredited, which is the fundamental point of Steyn’s book.
To educate readers, Steyn quotes about 150 Ph.D. scientists from every corner of the earth. He even uses the statements of a few liberal scientists who actually believe in MMGW, but who have no trouble denouncing the hockey stick… Several of the hockey stick’s most obvious problems are easy to grasp. The 900-year long handle completely ignores two indisputable eras, the Medieval Warm Period, from about 950 to 1250 A.D. and the later Little Ice Age from 1300 to 1850. For proxy measures, Mann and his team used only a few trees, including one California bristlecone pine, which is certainly old, but whose rings cannot determine climate. As stated by Dr. Jeffrey Foss, author of the 2009 book Beyond Environmentalism: A philosophy of Nature: “tree rings are not a reliable proxy for temperature.” After more critical analysis, Foss concluded, succinctly: “wrong tree, wrong proxy, wrong location, wrong method.”
You will love the 12 chapter titles, written in Steyn’s proverbial acerbic inflection, among them: “Mann is an island,” “Mann of the hour,” “Mann o’war,” “Mann overboard,” and my personal favorite, “Mann boobs.”
