Global warming scientist Michael Mann has lost a Canadian libel lawsuit he had filed against a skeptical scientist who had said that Mann “belongs in the state pen, not Penn State.”
More details here. The court also ruled that Mann must pay the defendant’s court costs. The key quote that proves Mann’s scientific work is either incompetent or fraudulent is this:
Dr Mann lost his case because he refused to show in open court his R2 regression numbers (the ‘working out’) behind the world-famous ‘hockey stick’ graph.
Mann is most well known for his hockey stick graph that eliminated any evidence of the well-documented Medieval Warming Period and thus made it appear global warming only began with the industrial age.
Many good scientists have questioned this graph, including Canadian scientist Dr. Tim Ball, the victorious defendant in this case. The court had demanded that to prove Ball’s statement was libel, Mann had to show everyone the legitimate scientific methods he used to create the graph. Mann refused to do so, and so the court ruled against him.
I should add that a number of different scientists have analyzed Mann’s hockey stick graph and have found that, based on the information in Mann’s own published papers, they could plug the data in and with his methods create any graph they wanted, essentially demonstrating that what Mann did was junk.
Does this prove human-caused global warming isn’t happening? No, it doesn’t. What it does demonstrate once again is that another one of the icons of that theory is either a fraud or incompetent, and that his work is not worth the electrons used to publish it. In the case of Mann, the evidence of his political biases and corrupt science practices has been evident for years, first exposed in his emails in the climategate emails. There, he actually worked to destroy the careers of any scientist who questioned his work, rather than debate the facts with them.
He tried to do the same this time with Dr. Ball, and has been soundly slapped down.
