What Really Happened During the Younger Dryas?

The Younger Dryas period, beginning around 12,900 years ago, marked one of the most dramatic climate shifts in Earth's recent history. In this episode, Randall Carlson examines the evidence for a sudden, global-scale catastrophe that may have triggered the extinction of megafauna, disrupted early human cultures, and initiated a centuries-long return to Ice Age conditions.

Drawing from geological records, impact proxies, and global flood myths, Carlson explores how a possible cosmic impact — or series of impacts — could have caused widespread wildfires, meltwater pulses, and atmospheric disruption. The conversation also touches on the limitations of the archaeological record and the possibility that earlier advanced civilizations were lost in the aftermath of this catastrophic reset.
