Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
We know almost nothing...

...and therefore we shouldn't be doing anything?  That's not a rational decision.

Assuming there are only two options (do nothing or put up an SO2 sunscreen), and both options are poorly understood, then it is still the rational thing to go through with the option where the better outcome is predicted.  No matter how large the uncertainties are.
