Great! Something else to worry about!

[VanShuyten]

Nah, too small. If you want to worry, Google Earth Toba. That huge lake in Sumatra is the result of a big blast about 75,000 years ago.

However, even this did not seem to affect the length or depth of the ice age that was going on at the time. Although the temperature did drop at that time, the temperature pattern doesn't really differ much from the previous ice age. So maybe, be happy, don't worry.
