The grift is even bigger than that. Scapegoating a naturally occurring gas for all of the world's problems is a huge opportunity for grifters, greenwashers, & con artists. I wonder if theres a study of scientists who add "the effects of global warming on..." to their paper titles for some career sustaining $$$. Don't get me wrong, there's plenty of great work out there...however the incentives seem to invite unethical behavior.
