I did like the theory that if you believe in human-contributed climate change and actively work to delay or prevent this, but in the end your belief was wrong, the worst thing you're doing is altering lifestyles that can again be changed and theoretically making the world a better place in the process, but for no real reason. If you don't believe and keep going as current, and you are wrong - you've actively helped kill the world. It's like when you bet against the Jerks, if they lose as predicted at least you have a form of win, but if they win you lose your money but they've won so you're happy. Working on the human-contributed climate change theory/belief is the lowest risk, highest gain path to take here - I haven't seen much to convince otherwise.
