I issued a public challenge to John Coleman back in early November. I posted my challenge here on my blog, but I also sent an email directly to him at the Heartland Institute. They responded by asking if I was the same Christopher Keating that did the Global Warming Skeptic Challenge and I told them I was. This shows they received my challenge, but I have not heard anything from them since.
This is just one more example that confirms my belief John Coleman is nothing more than a fraud. It's fine for him to go around making unsupported claims as long as he doesn't have to defend them. But, there is no way he will go into a public forum where he could be forced to justify his statements.
In any event, if you happen to figure out where he's hiding, let him know I'm still available.
