    The trouble with geoengineers “hacking the planet”

    To be sure, I can actually imagine a world in which a small and strictly limited amount of albedo modification could sensibly be deployed as a complement to strong and largely successful efforts to bring carbon dioxide emissions towards zero, accompanied by successful deployment of technologies for actively removing the gas from the atmosphere. But that would be a world with a truly exceptional level of international agreement, fact-based decision-making, and cooperation towards shared goals. A world where somebody like Donald Trump can become president of a superpower is not that world.
