Frequent PJ Contributor Christopher Horner and the American Tradition Institute have prevailed in a Freedom of Information lawsuit against the University of Virginia to force the release of retained emails from Dr Michael Mann.
Mann, currently at the University of Pennsylvania, was the primary author of the famous “hockey stick” report on paleoclimate data. The conclusion that Mann’s data indicates unprecedented anthropogenic warming has now been largely discredited by a National Science Foundation report.
The “hockey stick” was called by many a “smoking gun” proving that CO2-forced anthropogenic global warming was the primary cause of climate change observed over the last 1000 years. The chart is featured prominently in the Al Gore film, book, and presentation “An Inconvenient Truth.”
