Prof. J. Scott Armstrong, of the Wharton Business School, has challenged Al Gore to a $10,000 bet on temperature change over the next ten years. Dr. Armstrong is a pioneer of the theory of forecasting and he says (full text as pdf) that the IPCC report on global warming violates the basic principles of how a good forecast should be made. Actually, he says that Chapter 8 of the IPCC report contains 73 violations.
One of Prof. Armstrong's students has set up a blog devoted to the bet. Al Gore has not been willing to debate on the issue of global warming. Will he accept a bet?
