In fact, increasing Earth’s albedo by pumping certain types of chemicals into the higher layers of the atmosphere has been proposed as a possible geoengineering solution that could slow down global warming.

I wouldn’t be surprised if the entire project was architected as a way to completely sidestep regulatory approval and test geoengineering theories before climate change really starts to pop. Elon and his fellow plutocrats are undoubtedly sociopathic enough to do that.
