submitted by Huzzaz on 12/01/17 1

We don't need a time machine to learn from the past (but let us know if you find one)! Air bubbles trapped in ice for millennia and ancient pollen grains can tell us a lot about climate shifts hundreds of thousands of years ago! We're conducting a survey of our viewers!
