Episode 3: The Great Cooling

Created and narrated by Professor Dagomar Degroot of Georgetown University, The Climate Chronicles reveals how climate change has shaped humanity’s past—and what history can tell us about the future of global warming. With clear, dramatic storytelling, each episode brings history to life through gripping narratives and cutting-edge science.

 

In our third episode, the second of our first season, Becoming Human, Professor Degroot takes listeners through the dramatic cooling of our planet that began some 45 million years ago. He explains how climate change influenced evolution - including the evolution of our distant ancestors in a drying Africa. 

The Climate Chronicles is really an audio book. The first season gives a unique overview not only of how climate change may have created our species, but also of the history of science that revealed our origins, and the creative detective work that climatologists, archaeologists, and geneticists use to dive into the deep past.
