Why Won’t Al Gore Debate?

Avery is an agricultural yst and Lord Monckton is a publisher. Neither has actual credentials to be called an expert on this topic. While Gore is not a scientist, he has been involved with the topic for thirty years now, has done a lot of research, and actually listens to those scientists best qualified to understand the situation. I feel he would be more willing to debate legitimate climatologists who feel there is not man-made component to climate change. Finding them is the problem.
