A Massive Impact Crater Has Been Detected Beneath Greenland's Ice Sheet (gizmodo.com)
An anonymous reader quotes a report from Gizmodo: An unusually large asteroid crater measuring 19 miles wide has been discovered under a continental ice sheet in Greenland. Roughly the size of Paris, it's now among the 25 biggest asteroid craters on Earth. An iron-rich asteroid measuring nearly a kilometer wide (0.6 miles) struck Greenland's ice-covered surface at some point between 3 million and 12,000 years ago, according to a new study published today in Science Advances. The impact would've flung horrific amounts of water vapor and debris into the atmosphere, while sending torrents of meltwater into the North Atlantic -- events that likely triggered global cooling (a phenomenon sometimes referred to as a nuclear or volcanic winter). Over time, however, the gaping hole was obscured by a 1,000-meter-tall (3,200-foot) layer of ice, where it remained hidden for thousands of years. Remarkably, the crater was discovered quite by chance -- and it's now the first large crater to be discovered beneath a continental ice sheet.
It also caused climate change. We should outlaw asteroids, perhaps a bunch of world leaders could fly to Paris and sign an agreement saying that no more asteroids are allowed to hit the earth, or the US should pay for damages if one does.
Scientific credibility is akin to dinosaurs not having feathers for the last 150 years of science and then *poof* magically being discovered to have had feathers.

Isn't 12,000 --3,000,000 years a pretty big window?? Or is that par for the course?
