I think the real problem here is that BB just doesn't like Al Gore very much and resents the attention Al is getting these days... ;-) It is your resentment of Al Gore which keeps drawing you back to this thread to argue, BB, that's my opinion. It's a similar phenomenon to the way many of us are drawn to various threads to attack George Bush...because we resent him. It's irresistible.

By the way, I think you're right in much of what you say. Obviously there are a number of reasons for global warming, and human-based CO2 emissions are not the only one.
