About this video
Did you know that a massive ancient flood triggered a thousand year ice age? 13,000 years ago, North America seemed to be thawing from a 2.6 million-year ice age. Then, a huge swath of Earth was suddenly plunged back into the cold for 1,000 years. To understand why, join Stefan Chin and Blake De Pastino for today's episode where they'll unpack megafloods.
