Truthiness in action

John Coleman a.k.a. the guy who founded the weather channel is sure that global warming isn't happening. Personally, I really don't see how these people can justify this. Sure there is a possibility that global warming isn't happening...or we aren't causing it...or it's a scam brought on by eco-terrorists, but the fact there is a chance we are causing it makes it actionable. Let's put it in different terms, if you think there is a 50% change that a airplane you are about to board has a bomb on it...do cancel the flight...or wait until every scientist is 100% sure that there is a bomb before you take action. I'm for canceling the flight.
