The dustiest place on Earth is not surprisingly in the middle of the world's largest desert, the Sahara. More surprising is that crocodiles live there too, hundreds of miles from their nearest kin. How did they get there? Both facts have a common origin from a time when the Sahara’s climate was wildly different than today thanks to the effects of plants.
The 20 million years when earth was an ice planet
Dr. Kristin Poinar (Assistant Professor, Department of Geology, University at Buffalo)
As long as humans have been on the planet, glaciers have sat in Antarctica, Greenland, and sometimes Canada and Europe. Long before humans, planet Earth got stuck in a strange situation: glaciers entirely covered the earth, from the poles all the way to the equator. From space, earth would have looked like a big white snowball. Join us to find out what earth was like during this extreme climate, how it got there, and how our planet eventually broke free of
