I agree we shouldn't wait, but maybe the people who aren't on board would be more receptive to "the world is ending we're all going to die" doomsday preacher style I see so often.

I really think thought it really comes down to economics. Even if they do believe it's happening and it's urgent, the people's livelihoods who are threatened by elimination of carbon are going to come up with an infinite amount of rationalizations to put it off. It's also easy when it's not your job/money on the line to say "yeah we should fix this".
