Did a 'forgotten' meteor have a deadly, icy double-punch?

A team of Australian researchers suggests that a 2.5 million-year-old meteor impact in the Pacific Ocean may have generated a mega-tsunami and plunged the world into the Ice Ages. The Eltanin meteor, up to two kilometers across, crashed into deep water, potentially destabilizing the planet's climate system.
