Isn't the consensus from climate scientists that emission reductions are totally necessary, and there is no solution which is solely based on capture of greenhouse gases or cooling technologies? Even if reducing emissions is not enough, I thought it was clear that it needs to be done - and the economic impact is a necessary evil, since in reality we are just seeing the reversal of economic benefits obtained at the cost of planetary temperatures.

I haven't seen an analysis of stratospheric aerosol injection that suggested it couldn't solve the problem. We know it works because it happens naturally via volcanoes, and if we do it ourselves we can do it almost entirely without the other bad effects volcanoes cause. The opposition I've seen to it has been on moral or ethical grounds, or misunderstandings.
