I hear that argument lot, but the perspective that seems missing to me are the secondary effects - right now, we have a lot of self-reinforcing loops from rising temperatures, like melting permafrost emitting even more greenhouse gases. At least those should stop if the earth is artificially cooled down, no? If so, then it could be considered a form of preemptive removal - stop it from getting into the atmosphere in the first place. Not sufficient on its own, but a bandaid that would buy some time (which has its own risks, given our record of dealing with problems too late).
