Segura (University of Colorado) and her colleagues argue that hot ejecta produced by the very largest impacts might have affected the entire planet, creating enough heat to vaporize or melt the polar caps and near-surface ground ice, produce widespread rainfall, and maintain surface temperatures above freezing for as long as 1,000 years.
Instead, he notes, the small amount of water "may just be very local melting of near-surface ground ice," warmed by the planet's internal heat or perhaps by the sun during periods when the north or south pole is tilted closer to the sun.
