These people are no different than Young Earth Creationists (wouldn't be surprised if there was some overlap.). That is to say their views lead them to reject science rather than science informing their views. They should be learning to accommodate the science within their views. Denying reality leads to disaster.
Here's the thing instead of funding a campaign to sow fear, uncertainty, and doubt, why don't they fund actual science? Left and right should be debating on what to do about human caused global warming and not whether or not it is happening.
