Scientists Find Evidence For A 60 Mile Wide Comet That Plunged Into Earth Just 13,000 Years Ago

At the end of the Ice Age some 13,000 years ago, the northern hemisphere seemed to be hotting up as glaciers were retreating and grasslands spreading. But then something happened: there was a sharp drop in temperatures and a return to glacial conditions for another thousand years.
This sudden cooling event is known as the Younger Dryas, and the causes behind aren’t fully understood. Now a new study is claiming to have found further evidence for the argument that the onset of this cold period occurred after Earth was bombarded with comets that set off vast wildfires.
