Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Your point makes sense, but there's a question of what "a better predicted outcome" means. Obviously, an option with a better mean outcome could be worse overall than another, if it has considerably more uncertainty. (I'm just noting the effect of risk aversion here, and the meaning of "better" and "worse" could simply include this.)

In the present case, however, there's no conflict between expectation and risk. As best I understand it, the negative effects of unchecked warming also produce what seem to be far greater risks -- setting positive feedback loops in motion, changing weather patterns, possibly switching off the Gulf Stream...

...would presumably be done before anything of the magnitude of a massive SO2 release went forward.  

As it happens, we already know the consequences (smog, acid rain, global temperature drop if scale is large enough) of a massive SO2 release, as you have pointed out.  So the modeling should not be too fraught with uncertainties.  

Carbon sequestration, which is on everyone's lips these days, is a most likely a problem with more uncertainties--how carbon dioxide will affect subterranean rocks and soils; question of leakage and release after a few hundred years, etc.

Yes, but this wouldn't be a massive SO2 release: it would be a small release (by global emission standards), but in a more effective place, well above typical jet cruising altitudes.
