A comet or asteroid that landed at Quebec, Canada, might have led to the drastic climate change about 12,900 years ago, according to a new study.

The study was conducted by researchers at Dartmouth College and their colleagues. Their research challenges the idea that the Younger Dryas stadial or the Big Freeze was caused by rise in meltwater from the North American ice sheet. According to them, an object from space, a comet or asteroid was behind the dramatic shift in climate across the world.
