We are already doing some geo-engineering. That’s what putting megatonnes of greenhouse gases up the atmosphere is. We’re just too stupid and shorts-sighted to do it in any useful way.

That said, piling more geo-engineering on top of the problem will not solve it. It will just create more issues with unforeseen consequences and instability. What we really need to do is to reduce emissions. It’s much simpler and cheaper than any form of geo-engineering you could think of to mitigate the consequences.
