I thought it was a very fair book that brought out the fact that popular science - which is essentially what global warming is - is a sort of Chicken Little rumor factory that has people believing the rumor despite all evidence to the contrary. The Great Population Explosion was an example of this.
However, when the sky does not fall and it all turns out to be a rumor, there is never any formal retraction of the "science" that led to this, but simply a shift to the creation of another rumor.
I liked the book a lot, btw, and I found it a real page turner!
I thought it was a page turner too. My favorite Chrichton book was "The Great Train Robbery," I think. I liked the movie, with Sean Connery alot also.
