I'm not convinced that geoengineering is feasible when we can't even seem to stop churning CO2 into the atmosphere. It's far easier to stop the fossil fuel burning than to scrub the atmosphere or set up huge space mirrors, so why do you think that we'll manage to fix the climate? Far more likely is a massive population die off and a collapse of our modern society. At least some people made a lot of money from burning our future.

It's far easier to start doing stratospheric aerosol injection than to stop burning fossil fuels.

		However, we don't know the best substance to use and we certainly don't know what kind of side effects it would have. Historically, humans have been very bad at predicting bad side effects (e.g. cane toads in Australia) so I am sceptical, especially when businesses will be trying to make profit from it. It seems to me like the start of a dystopian sci-fi story with humanity retreating from the surface as acidic rain destroys all plant life.
