It's because the majority of the people who believe in climate change as chanted by the enviro-nazis are sheep. The data is inconclusive as to whether something is on a true trajectory of climate warming vs just a fluctuation that happens in a normal cycle. The people who stand to gain the most aren't in it for the money. It's the power. Climate change crisis = government regulation, just like shooting tragedies = government regulation, just like a lack of birth control pills = government regulation, ad nauseam.
