"Estimates of future impact hazards, which rely upon inaccurate impact-dust loadings, are greatly overstated."
-- Kevin Pope, Geology, February 2002

"Based on the old, inaccurate dust numbers, which erroneously suggested that a medium-sized asteroid (1-2 km in diameter) could cause global climate change and famine, scientists calculated that one's chance of getting killed by an asteroid impact were about the same as dying in a plane crash. My new impact dust estimates indicate that death by an asteroid is far less likely and that such medium-sized asteroid impacts would not have catastrophic global effects. But of course the regional effects would still be devastating."
