There's also a theory that Mt. Toba, a really big volcano on Sumatra, erupted during the ice age, and the resulting "nuclear winter" killed off everyone, except for a few thousand Neanderthals. I don't know about that, but if Mt. Toba blows in our lifetime, it's safe to say that we'll never have to worry about global warming again!

Never mind Toba... I've read and seen a few items recently that there is a potential supervolcano under Yellowstone, just waiting to go.

It has been determined that the Yellowstone super volcano erupts about every 600,000 years. It has been 640,000 year since it last erupted. Ahem, prepare now.
