Couldn't one try to at least limit the feedback loop by spreading sulfur over the affected regions by plane? (Simulating a volcanic eruption that reflects sunlight)

We will almost certainly be spraying sulfur dioxide (and dealing with the acid rain) in the next few decades. It will be too little too late though.

Why simulate a volcanic eruption? We could just bury some nukes in some volcanoes and blow the tops off. Instant cooling!

Also, I hear nuclear winter is really 'cool'. We could always start a war in Korea...
