i'm just wonderin'-- the last time there was such an eruption was Toba nealy a century ago-- about the same time the Ice Age started. So here's my question--should a supervolcano erupt, will we die as it might cause another Ice Age?

No. Ice Ages are caused when two things happen at the same time. When once every tens of thousands or hundreds of thousands years the earth is farther away from the sun than at at time previously in its orbit and the tilt of the earth is such that the suns rays must pass through too much of the atmosphere on an angle to warm the earth. Generally volcanoes which release greenhouse gases are thought to actually warm the earth up over time. There was a theory called snowball earth where it is suggested the entire planet was covered in snow and ice and volcanic activity eventually melted all the snow and ice and caused the planet to heat back up again.

There are a lot of volcanos that never have been discovered on the ocean floor. Think about it-the crust is much thinner under the ocean and 2/3s of the surface is under water so is it not reasonable to assume there are a lot more volcanos on the seabed than we see on the land? They come and go so it is quite logical that heat from this has an effect on iceages and everything else don't you think?
