Clip: Season 5 Episode 6 | 4m 56sVideo has Closed Captions
Physical evidence of earth's climate swings.
For years some scientists have hypothesized about the existence of the earth’s natural climate cycles. Now, some researchers believe there is physical evidence to support this. Dennis Kent, an expert in paleomagnetism, the study of magnetic fields in rocks, has co-authored a study that analyzes rocks to show how the earth’s climate is dictated by cycles. He joins Hari Sreenivasan to discuss.
