Wizards and prophets face off to save the planet
Wizards typically favor something like solar radiation management, which is essentially sprinkling tiny reflective spheres in the upper atmosphere to bounce back a little of the sunlight, just enough to buy us more time. It would actually be cheap and efficient; it’s kind of horrible to put it that way because nobody in their right mind would be enthusiastic about it. You just need a couple of airplanes sprinkling stuff up there, and it could be done for a couple billion dollars a year. So in a country like Indonesia, which is at risk of losing significant territory to sea rise, and has something like 60 billionaires — you could imagine it right? An individual billionaire might just choose to do this. Prophets see this as crazy, as fighting pollution with pollution.
