Randall Carlson, the Younger Dryas, and the science behind catastrophic climate shifts.

In this episode of The Lost Civilizations, we examine Randall Carlson’s views on catastrophism, cyclical risk windows, and the controversial Younger Dryas Impact Hypothesis. Often associated with Ancient Aliens, Carlson does not argue for extraterrestrial intervention. Instead, he explores whether Earth’s history includes abrupt climate shifts, megafloods, and possible cosmic events that reshaped early human civilization.

We review the evidence for and against the impact hypothesis, including platinum anomalies, proposed impact markers, and competing explanations such as disruption of the Atlantic Meridional Overturning Circulation (AMOC). We also explore why complex, interdisciplinary ideas are frequently polarized or misrepresented in public discourse.

Are catastrophic events cyclical? Is this about probability or prophecy? And how should we approach scientific uncertainty without collapsing into speculation?

This episode examines geology, climate history, and the politics of complexity — not apocalypse narratives.
