Really?Muller's a liar when he calls himself a skeptic. Everything he says can safely be dismissed.
Lot's of flap yap and nothing at all to back it up. You are firing blanks, Davey Boy.
In a 2004 Technology Review article,[9] Muller supported the findings of Stephen McIntyre and Ross McKitrick in which they criticized the research, led by Michael E. Mann, which produced the so-called "hockey stick graph" of global temperatures over the past millennium, on the grounds that it did not do proper principal component analysis (PCA).[10] In the article, Richard Muller stated:Now tell us the AGW believer didn't say what he said.
McIntyre and McKitrick obtained part of the program that Mann used, and they found serious problems. Not only does the program not do conventional PCA, but it handles data normalization in a way that can only be described as mistaken.He went on to state "If you are concerned about global warming (as I am) and think that human-created carbon dioxide may contribute (as I do), then you still should agree that we are much better off having broken the hockey stick. Misinformation can do real harm, because it distorts predictions." Muller's statements were widely quoted on skeptical blogs, and his status as a believer in global warming made his criticism of the "hockey stick" particularly damaging. In response, Mann criticized Muller on his blog RealClimate.[11] Marcel Crok, a reporter for the Dutch popular science magazine Natuurwetenschap & Techniek, later did a story on the incident.[12]
Now comes the real shocker. This improper normalization procedure tends to emphasize any data that do have the hockey stick shape, and to suppress all data that do not. To demonstrate this effect, McIntyre and McKitrick created some meaningless test data that had, on average, no trends. This method of generating random data is called "Monte Carlo" analysis, after the famous casino, and it is widely used in statistical analysis to test procedures. When McIntyre and McKitrick fed these random data into the Mann procedure, out popped a hockey stick shape!
That discovery hit me like a bombshell, and I suspect it is having the same effect on many others. Suddenly the hockey stick, the poster-child of the global warming community, turns out to be an artifact of poor mathematics. How could it happen?[9]
Wow Dave -- That's really really sad news for Ole Roxy who's STILL to this day insisting that the Hockey Stick is absolutely correct..
