I think this would be a great market for suborbital space transports.

Interesting, Rand. Interesting enough that I
have filed it away. However, the first stage of
an orbital sytem might be more appropriate
than a "suborbital" system--at a least suborbital
system that is designed to go to 100 km.

Our carrier stage could lift about 200 tonnes
to 30-40 km for under $1 million per flight.
The volcano equivalent--10 million tonnes--
would require require perhaps 50,000 flights.
At that rate, cost per flight should come down
quite a bit. $100,000 per flight would cost
$5 billion. However, it may, or may not, be
more cost-effective than sun-synchronous or
other shading/deflection--or, as Joe Strout,
suggests, balloons.

Emissions controls--carried to extremes--could
prove the most costly and least practical.
