I was at a meeting earlier this week and was talking to one of the coordinating lead authors of the recent IPCC working group 1 report on the physical science of climate change. He remarked that he was quite surprised that how little substantive criticism the IPCC Fourth Assessment Report had received since its release just about one year ago.

The reason, he thought, was that the skeptics were “in the room” with the writing team. What he meant was that the scientists writing the report knew that the denial machine would go over the report with a fine tooth comb looking for any “gotcha” mistakes to use to discredit the IPCC. Because of that, the IPCC report was extremely carefully worded so as to make virtually every statement in the report bulletproof.

In fact, it is quite amazing to me that essentially none of the IPCC documents produced over the last 18 years has been found to contain any substantive errors. The trolls, of course, will come out with their litany of “errors” that the IPCC contains (I suspect a few will appear in the comments to this post), but when you look closely, the trolls are almost always misrepresenting the IPCC’s statements.

In fact, that’s the most common attack on the IPCC: make the claim that the IPCC said something ridiculous (which it didn’t actually say), then disprove that ridiculous statement, and then use that as evidence that the IPCC’s reports cannot be trusted. “The IPCC says that 2 + 2 = 5, but that’s just hogwash. We know that 2 + 2 = 4. Thus, climate change is a hoax.” Yeah, right.
