The Sulfur Shade Solution

Paul Crutzen Proposes Temporary Global Warming Relief
by Injecting Sulfur Into The Atmosphere.
He doesn't suggest this as alternative to reducing global warming polution.
Rather, he says progress on that front is going too slowly to stave off disaster.
Putting a "sulfur shade" up in the sky would buy us time to get our act together.
Or would it mess things up ever further? I'm thinking the "Don't Mess with Mother Nature" adage would apply here, but it might be a last ditch effort if things get really bad.
