`Auckland University scientists have revealed that eruptions of supervolcanoes powerful enough to change the climate and cause mass-extinction can be worse than previously thought. [..]
Such large eruptions of greater than 100 cubic kilometres of magma are generally rare and random events worldwide.
But geologist Darren Gravley of Auckland University and his colleagues have shown that one of the largest supervolcano eruptions on record, at Taupo 250,000 years ago, was twice as big as previously thought.’
Maybe I’m a bit stupid, but I don’t see how much worse than mass-extinction it could get. [shrug] It’s not like we’re going to be thinking “Oh, I’m glad it wasn’t any worse” once we’re already dead. 🙂
