Who does Al Gore sue?

TORONTO - A volcano has erupted on a tiny island off the coast of Yemen, spewing
lava and ash hundreds of feet into the air, a Canadian naval vessel near the
island in the Red Sea reported Sunday. There were no immediate reports of
deaths, but at least eight people were missing.

So starts the AP story. Now with a volcano spewing out tons of sulfur dioxide and other nasty stuff into the air, who do we sue for the release of greenhouse gasses and other pollutants?

Al Gore call your office we need you to tell us who is going to pay for this blatant pollution problem.
