You will never have 100% consensus on any scientific issue. There is too much hay to be made on a margin for a denialist. There are scientists who believe that HIV doesn't cause AIDS, either. It doesn't mean they are anything less than ill-informed whackjobs.
It's not a coincidence that an overwhelming majority of Americans believed in man-made climate change a decade ago, and now only half do. That decade has corresponded with one of the most aggressive anti-science movements in the history of the country.
Die, Steckel. Die.
