And cause health problems, acid rains and much more. It is not a solution.
With complex systems touching a variable impacts a lot of places, something that may become obvious in hindsight. Undoing how we triggered climate change, that is first drastically reducing emissions and then capturing the excess of greenhouse gases, looks like a less disruptive way to effectively solve the problem.
My prediction is that at some point in the next 50 years the problems of SO2 will be considered an acceptable tradeoff for the cooling. At least one major world government (or perhaps sufficiently wealthy oligarchs) will begin intentionally pumping SO2 into the atmosphere.
It is kinda nihilist statement. But most efficient tool against climate change is population reduction in places that produce most emissions per capita.
