Professor Ted Bryant discusses geomorphology and climatology evidence for catastrophic changes to earth's surface. Bryant examines geological evidence for mega-tsunamis and catastrophic flooding events in earth's history. The conversation explores climate patterns and evidence that rapid dramatic changes have occurred repeatedly. Bryant discusses asteroid impacts, volcanic eruptions, and other catastrophes that reshaped continents and climate. The discussion addresses whether earth is overdue for catastrophic events and what warning signs exist. Bryant examines evidence that civilization-ending catastrophes have occurred within human history. The broadcast explores the relationship between climate change and geological catastrophes. Bryant discusses whether current climate shifts presage another period of rapid dramatic change. The conversation addresses humanity's vulnerability to natural catastrophes and whether civilization could survive mega-disasters. Bryant examines what geological records reveal about earth's violent past and the cyclical nature of catastrophe.
