The Climate Chronicles
Today’s global warming has no precedent in Earth’s history. Yet long before we started overheating the planet, natural climate changes shaped our past. In the Climate Chronicles, Dagomar Degroot, one of the world’s leading historians of climate change, explains how climate change influenced humanity’s history, from the evolution of our species to the onset of today’s climate crisis.

Created, narrated, and produced by Professor Dagomar Degroot of Georgetown University, The Climate Chronicles reveals how climate change has shaped humanity’s past, and explores what history can tell us about the future of global warming. With clear, dramatic storytelling, each episode brings history to life through vivid storytelling and cutting-edge science.In the fifth and final episode of our first season, Becoming Human, Professor Degroot tells the epic story of how climate change spurred the evolution of the last hominin species - including our own. He explains how ancient DNA is uncovering previously hidden chapters in this remarkable tale. He shows how industrialization and famine originally brought it to light. And he closes the season by considering the implications of the deep histories we've explored in the past five episodes. The Climate Chronicles is really an audio book. The complete 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.

In the fourth episode of our first season, Becoming Human, Professor Degroot explores how our hominin ancestors learned to cope with, and even exploit, the wildly fluctuating climate of the Pleistocene. He uses the extraordinary migration of a hominin species named Homo erectus to introduce the concept of resilience: a key but contested term that can help us understand our fate on a warming world.

In the third episode of our first season, Becoming Human, Professor Degroot touches on everything from Noah's Flood to nuclear submarines in telling the strange, three-century-long history of the discovery of the Ice Age. Then, he explains why rapid climate changes of remarkable intensity threatened our ancestors in the world of the late Pleistocene Epoch.

In our second episode, the first of our first season, Becoming Human, Professor Degroot introduces the far-fetched possibility that humanity might not be the first intelligent species to overheat the Earth. By investigating this idea, Degroot explains how scientists piece together the deep history of climate change on Earth.

In our introductory episode, Professor Degroot uses one of the great adventure stories of the seventeenth century - the tale of fourteen desperate men deserted on two tiny Arctic islands - to explain why the history of climate change matters so much today. Along the way, he shows what climate change actually is, describes how we can trace it into the deep past, and reveals why it's so hard to identify its influence on human history. The effort to recover climate's past is all about creative detective work - the kind that can uncover how a small group of men survived, and died, centuries ago, in some of the extreme environments on Earth.
