Previous studies have suggested that Indonesia's Toba supervolcano, when it erupted about 74,000 years ago, triggered a 1,000-year episode of ice sheet advance, and also may have produced a short-lived "volcanic winter," which drastically reduced the human population at the time. Researchers have now found that none of the models to simulate the supervolcanic eruption initiate glaciation.
