In the Shadow of the Sabertooth A Renegade Naturalist Considers Global Warming, the First Americans and the Terrible Beasts of the Pleistocene

Our climate is changing fast. The future is uncertain, probably fiery, and likely terrifying. Yet shifting weather patterns have threatened humans before, right here in North America, when people first colonized this continent. About 15,000 years ago, the weather began to warm, melting the huge glaciers of the Late Pleistocene. In this brand new landscape, humans managed to adapt to unfamiliar habitats and dangerous creatures in the midst of a wildly fluctuating climate. What was it like to live with huge pack-hunting lions, saber-toothed cats, dire wolves, and gigantic short-faced bears, to hunt now extinct horses, camels, and mammoth? Are there lessons for modern people lingering along this ancient trail?

The shifting weather patterns of today—what we call "global warming"—will far exceed anything our ancestors previously faced. Doug Peacock's latest narrative explores the full circle of climate change, from the death of the megafauna to the depletion of the ozone, in a deeply personal story that takes readers from Peacock's participation in an archeological dig for early Clovis remains in Livingston, MT, near his home, to the death of the local whitebark pine trees in the same region, as a result of changes in the migration pattern of pine beetles with the warming seasons.

Doug Peacock is the author of Grizzly Years, Baja, and Walking It Off: A Veteran’s Chronicle of War and Wilderness. His latest book, co-written with Andrea Peacock, is The Essential Grizzly: The Mingled Fates of Men and Bears. A disabled Vietnam veteran and Green Beret medic, Peacock was the real-life model for Edward Abbey’s George Washington Hayduke. He has published widely on wilderness issues ranging from grizzly bears to buffalo, from the Sonoran desert to the fjords of British Columbia, from the tigers of Siberia to the blue sheep of Nepal.
