It was the biggest bang in human history. Around 75,000 years ago, the Toba supervolcano exploded on the Indonesian island of Sumatra, blasting enormous volumes of gas and ash into the air. Yet a new analysis suggests it had little impact on the climate, or on humans. So could such vast eruptions be survivable?…Geophysicist Alan Robock of Rutgers University in New Brunswick, New Jersey, isn’t convinced. Robock studies volcanoes’ effect on climate, and agrees Toba probably didn’t cause a 1000-year chill. But the short-term cooling would still have been devastating, he says, and might have been too brief to show up in Lane’s temperature record.
