Episode 49 :: Jeff Severinghaus: How 800,000 Year Old Antarctica Ice Confirms Earth's Changing Climate & How to Respond
Geoscientist Jeff Severinghaus is rigorously committed to saying neither more nor less on climate change than what science can determine. With unassuming presence, which comes through in the interview featured on this episode, he presents the results of his field work extracting cores of ice from the Antarctica. From ice that dates back up to 800,000 years, he can tell what the atmosphere was like then and compare it to what is happening today. He answers the question: How much climate change is cyclical and how much of what’s happening today is different from anything in the history of our species? He also shares his hopes for humanity coming together in new cooperative ventures in the face of the challenge.
