Michael Mann Is A Liar and a Cheat. Here’s Why. | Power Line http://www.powerlineblog.com/archives/2014/05/michael-mann-is-a-liar-and-a-cheat-heres-why.php …
Michael Mann is one of the most partisan advocates for the catastrophic anthropogenic global warming theory. He is controversial for several reasons: he invented the “hockey stick” graph, which was intended to show that recent warming trends were unprecedented, and has since been exposed as a hoax that misrepresents historic temperatures. He has fought bitterly to prevent his own emails from being discovered in litigation, even though he is a public employee whose research is lavishly funded by taxpayers. He has participated in some of the dishonest “tricks”–their word–by which climate alarmists have kept billions of dollars in government money flowing their way.
Along with his other faults, Mann is litigious. He has sued National Review, the Competitive Enterprise Institute and Mark Steyn for criticizing him, a case he inevitably will lose.
It is generally believed in the scientific community, I think, that Michael Mann is a fraud and a liar, as well as a bully. To understand why, check out Steve McIntyre’s post at Climate Audit on Mann’s effort, along with others in the alarmist community, to bury the post-1960 tree ring data that contradicted Mann’s hockey stick.
Over the years, climate scientists have used tree rings–i.e., the width of tree rings in certain locations and in certain years–to reconstruct historic climates. Reliance on tree ring data is controversial, for obvious reasons: can we really determine temperatures 1,000 years ago by measuring rings in a particular tree, or group of trees, in a random location? Many are skeptical, but alarmists needed tree ring data to negate the overwhelming evidence of temperature variation in the past, e.g., the Medieval Warm Period. The problem was that the same tree ring data that the alarmists needed to smooth out past ups and downs in the Earth’s climate showed cooling, not warming, after 1960.
John Christy was a Lead Author of the Third Intergovernmental Panel on Climate Change, whose report was published in 2001. In Congressional testimony, he explained how a politically-motivated desire to promote the hockey stick caused Michael Mann and others to falsify data:
