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. Suppose, for example, that future measurements in the years 2005-2015 show a clear and distinct global cooling trend (It could happen). If we mistakenly took the hockey stick seriously--that is, if we believed that natural fluctuations in climate are small--then we might conclude (mistakenly) that the cooling could not be just a random fluctuation on top of a long-term warming trend, since according to the hockey stick, such fluctuations are negligible. And that might lead in turn to the mistaken conclusion that global warming predictions are a lot of hooey. If, on the other hand, we reject the hockey stick, and recognize that natural fluctuations can be large, then we will not be misled by a few years of random cooling. A phony hockey stick is more dangerous than a broken one--if we know it is broken. It is our responsibility as scientists to look at the data in an unbiased way, and draw whatever conclusions follow. When we discover a mistake, we admit it, learn from it, and perhaps discover once again the value of caution.
So junkscience.com is right: Richard Muller was never a true AGW skeptic.
But they go beyond that point by claiming that he is a "Climate Profiteer"
profiting on AGW alarmism. Of course, this is much like calling Home Depot and Lowe's disaster profiteers because they warn people to be prepared for disasters while at the same time selling just what those same people need to prepare for (or repair) damage from disasters.
Thanks a bunch for finding this Ody - I've been hunting it since the subject arose. I knew I had Muller on the alarmist list but I could not find the evidence.
