Thirty years from now, climate issues won't even be a concern, and we'll all fondly remember when we worried about it, much as we old folks all remember when global cooling was a major crisis.This will happen because (a) we'll have figured out cheaper, more efficient, carbon-free ways to generate electricity and move vehicles, and (b) we'll have figured out a way to turn carbon into something valuable instead of the silly notion that we exhale poison.
