How about this, and let me know if it's fair:
I'll watch Al Gore's An Inconvenient Truth, if you read Michael Crichton's State of Fear.
I know a book takes a little more time (and maybe money if you can't borrow it), but I think it would be interesting for us both to come back to one another afterwards and debate it in a new thread.
Obviously, if you've already read the book, I'll go ahead and watch the movie.
PS. I realise Crichton's work is officially fiction (as opposed to Gore's), but it does contain loads of referenced facts, which you're welcome to check up.
