I think that climate change absolutely is faith based and political. And we shouldn't be afraid of that. Lots of changes in human behaviour have a faith and moral component. Just think about hand washing. People don't need to understand microbiology to wash their hands. They need social pressure and a sense of morals.
Climate change deniers see environmentalism as a faith based political movement. Well it is. Even if you believe in climate change, there is nothing that says we have to do anything about it! It is perfectly reasonable to just shrug your shoulders and not do anything. The drive to protect the planet is a matter of conscience. And that is how people need to be pursuaded. Science is just not very convincing in everyday life, even among educated rational people.
