Dr. Vincent Gray is a member of the IPCC, and has been since it's inception. He thinks the IPCC is corrupt and should be disbanded. Here are his comments on problems with the IPCC. (I have come to think that the temperature record used by the IPCC is bogus, and have long thought that the global circulation models used to project future temperature increases are flawed based on my own experience with large thermal models which showed that validation of the models with test is necessary. The projections made by the IPCC mdels 20 years ago have simply not come true.)
