"Avoid Michael Chricton like the plague. Don't read things sponsored by the American Enterprise Institute or anything by any other "think tank""
Michael Chricton is no conservative and he admits that he never set out to write a book about the environment. In several interviews he said that he stumbled in to some of the conflicting data and started researching his confusion. He never wrote the book he was doing research for and instead wrote his envro-whacko hit peice.
Still, he's a novelist. Don't get science from Novels, and I won't Steven Hawking if I want fiction. Seems a fair deal
