Follow the money. The denialists like to say that climate scientists only say what they say for the money, but truth be told, the money is orders of magnitude larger on the energy provider side. They stand to have invest billions in new technologies, if AGW is accepted as fact. So, it is about the money, but dcn't get fooled by the denialist sleight of hand about who profits the most. Their spokes"scientists" get paid millions and don't even have to do any research to prove their contentions, unlike those who work on government grants at 1/10 the salaries.
