Michael Crichton's new book "State of Fear" addresses this very issue. Good read.
Also have a look at Jack DuBrul's "Deep Fire Rising" from about a year ago.
Bought the book for my wife for Christmas and I'm into the fourth or fifth chapter. I can hardly wait to hear (what I expect will be) the guy from MIT explaining to the billionaire donor how bogus the whole idea of human responsibility for "global warming" is.
