Blind faith and superstion combined with distortions amd lies cannot stand up in a reasoned debate. The Goracle won’t debate because he knows that he would loose badly, badly enough that some cult members would drop out of the Church Of Man-made Climate Change.

1) He believes he’s too important to stoop to debating
2) He’s such a glassy-eyed zealot he thinks debating about this is like debating about whether the sky is up
3) He knows he’d get crushed in any sort of scientific debate where he wouldn’t be able to lie, distort, and use old failed data without question like a movie or a speech

And that’s probably the biggest reason of all
