It's fine to worry about CC, I do myself, but the hard bottom line reality is the "we" globally are NOT going to do nearly enough to stop it.
My real hope is that the models are wrong, and not in the bad way.
This idea the US can spend money to do "something" will make more than a tenth of a degree difference is just technically incorrect. We're behind the curve already. This is why you never see a realistic PLAN to make a real change. There isn't one.
