Years ago, there were shysters that claimed to be able to cause rain by boiling off various vapors into the atmosphere, and actually got paid for it, iirc. Nowadays, we have shysters who claim that other people's boiling fumes don't just cause a storm, they change the whole planetary climate. But other things remain equal — they still get paid, and they're still shysters.
Not only do they get paid, but I understand some of these shysters win academy awards, noble prizes,have even been Vice Presidents and actually have been taken seriously as a potential President of the United States.
I like to think that the American people are not that gullible.
