Giant meteorite crater bigger than Paris found beneath Greenland’s ice sheet

Impact could have ‘drastically altered the climate and led to serious consequences for life on Earth at the time’, scientists say. A giant crater that was formed when a meteorite smashed into Earth, has been uncovered deep below Greenland’s ice sheets. The 31-kilometre-wide cavity was discovered by an international team of scientists who believe it was caused by a “rare” meteorite that struck Earth as recently as 12,000 years ago.
