Continuing as we are is equally devastating to not only humanity but the ecosystems of the entire planet. What’s worse? We take a huge hit and leave something for when humanity recovers or drive everything into catastrophe and there’s nothing left, especially not us? It’s not whether we can’t run air conditioners anymore, it’s that the entire tropics will be uninhabitable, the seas belching jellyfish into the streets of flooded cities, and every human left will have fought countless marauders to keep one tiny bit of inhabitable space. It’s game over already for a lot of things. Why not try to stop some of the worst of it before we lack the technical capacity to engineer a stop? Invest everything, and I mean everything to the effort. Take the hit. Figure a lot of us won’t make it. Apologize to everything.
