Geologists have decided to worry about the odds of a "super-volcano" erupting. "Experts weigh super-volcano risks" reports that they think these happen in the range of once per 100,000 years. They think that this could devastate food production and communication, causing starvation that would far outstrip the recent tsunami. Oh, and it would drop global temperatures 5 to 10 degrees Celsius, or about 9 to 18 degrees Fahrenheit. Could this be a cure for global warming then? ;-)
