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 the fifth and final episode of our second season, Escaping the Pleistocene, Professor Degroot reveals how an extraordinary rise in sea levels, about 10,000 years ago, overwhelmed ecosystems and human populations from Europe to Australia. He evaluates whether ancient myths and legends, including the story of Atlantis, preserve traumatic memories of early Holocene flooding. And he provides some broad reflections on the 100,000 years of human and climate history covered in this season. Season two of The Climate Chronicles is an immersive journey through the extreme climate shifts that influenced some of the most important events in the history of our species, from a wave of extinctions that transformed ecosystems around the world to the emergence of agriculture. The season also explores the history of the sciences that have revealed how climate change shaped our deep past.

In the fourth episode of our second season, Escaping the Pleistocene, Professor Degroot unpacks concepts such as radiocarbon dating and climate vulnerability to explore the ingenious and diverse ways in which our ancestors coped with the Pleistocene's final, and in many ways most spectacular, climate changes. He explains how everything from asteroid impacts to volcanic eruptions may have triggered the dramatic breakdown in ocean currents responsible for the most recent of these changes, a thousand-year cold snap known as the Younger Dryas. Finally, he surveys cutting-edge research that suggests we might soon face a similar breakdown—with profound implications for our modern world.

In the third episode of our second season, Escaping the Pleistocene, Professor Degroot provides different explanations for what may be the ultimate climate change disaster: the extinction of our closest relatives, the Neanderthals, a hominin species that may have been as smart as us. He shows us how new computer models can help us understand the possible causes for the disappearance of the Neanderthals, and considers whether their extinction provides a warning for our future.
