If I were king of the world, I could've fixed global warming in the 70s. It would cost a lot, there might've been a few more nuclear accidents, but it would be done by now - we'd be talking about how great our electric cars are going to be. Which is to say: we have the technology, if we're willing to pay for it, to fix this problem entirely by multiple means today (solar, wind, batteries, nuclear etc.). It'll cost a lot less then "we must fundamentally reshape humanity". But that's the problem with big problems: everyone uses them as a bandwagon for whatever unrelated issue they want to dump on it. So many people who practically want an apocalypse so they can "tut-tut" their neighbor who doesn't quite do recycling they way they think they should or whatever.
