A Warning From the Past

4 out of the past 5 extinctions were likely NOT caused by asteroids hitting the Earth. They were rapid climate change events. In this one hour lecture, Dr. Andrew Glikson of ANU Australia explains our real past. And why we are hurtling toward a cliff of mass extinction as we pollute a fragile atmosphere.
