12,800-Year-old Microspherules/Cometary Dust Suggest Younger Dryas Impact w/ Marc Young

Join us for an exclusive interview with Marc Young, a PhD candidate in Geoarchaeology at Flinders University and co-author of the groundbreaking paper published in PLOS One (August 6, 2025). In this fascinating discussion, Marc dives into the Younger Dryas Impact Hypothesis, exploring new evidence from Baffin Bay ocean sediments that suggests a comet impact 12,800 years ago may have triggered a dramatic global cooling event. Discover how his team’s advanced analysis uncovered geochemical clues, including microspherules and metallic dust particles, that point to a cosmic event potentially reshaping Earth’s climate. Marc shares insights on the research process, the significance of these findings, and the ongoing quest to confirm whether this extraterrestrial encounter caused the Younger Dryas cool-off. Don’t miss this deep dive into a pivotal moment in Earth’s history!
