Climate Fraud: In an attempt to defend his role in the greatest scam of modern times, Climate-gate's poster child threatens to defend his tarnished reputation in court. First, hide the decline, then hide the deceit.
"Get lost" was National Review editor Rich Lowry's appropriate response to a threatened lawsuit by Penn State climate scientist Michael Mann.
NR printed a post by the great Mark Steyn, who graces these pages as well, calling Mann's famous hockey-stick graph "fraudulent." That it is indeed a fraud has been documented by many, including us.
Mann was at the heart of the Climate-gate scandal in 2009, when emails were unearthed from Britain's Climate Research Unit (CRU) at the University of East Anglia. In one email sent to Mann and others, CRU director Philip Jones speaks of the "trick" of filling in gaps of data in order to hide evidence of temperature decline:
"I've just completed Mike's nature trick of adding in the real temps to each series for the last 20 years (i.e. from 1981 onwards) and from 1961 for Keith's to hide the decline (in global temperatures)," the email read.
It was that attempt to "hide the decline" through the manipulation of data that helped bring down the global warming house of cards.
The graph created by professor Mann and his colleagues carefully selected and manipulated tree-ring data to supposedly prove that air temperatures had been stable for 900 years, then soared off the charts — in a pattern resembling a hockey stick — in the 20th century due to man-made greenhouse gases. Mann et al. performed the neat trick of making the Medieval Warm Period (about A.D. 800 to 1400) and the Little Ice Age (A.D. 1600 to 1850) statistically disappear.
The graph relied on data from trees on the Yamal Peninsula in Siberia. Here too the data were carefully selected. Data from just 12 trees from the 252 cores in the CRU Yamal data set were used.
A larger data set of 34 tree cores from the vicinity showed no dramatic recent warming, and warmer temperatures in the Middle Ages. They were not included.
Based on this documented record of scientific fraud, Steyn posted a stinging critique that included this quote from the blog of Rand Simberg: "Mann could be said to be the Jerry Sandusky of climate science, except that instead of molesting children, he has molested and tortured data in the service of politicized science that could have dire economic consequences for the nation and planet."
