Yet another money quote:

[Director of the Potsdam Institute for Climate Studies in Germany Hans-Joachim] Schellnhuber acknowledges the difficulty of interpreting the IPCC's temperature-increase predictions for the end of the century, which range from 1.4 degrees centigrade to 5.8 degrees. "There is a certain arbitrariness," he says. "Two Japanese models, one showing a 9-degree warming and the other showing zero warming, were thrown out because they were felt to be too far outside the range. So you take all these models and average them out, and you get a 3- or 4-degree warming. What does it mean?" He shrugs. "If one model is operating on wrong principles, all of them are off."
