Roughly 12,800 years ago, three things happened simultaneously: an abrupt cooling of up to 20°F in Greenland within years, the extinction of roughly 35 genera of North American megafauna, and the total collapse of Clovis toolmaking culture. The mainstream meltwater explanation accounts for the temperature shift but nothing else, and Wallace Broecker spent decades searching for physical evidence of the flood mechanism without conclusively finding it. The 2007 comet hypothesis, proposed by Richard Firestone, Allen West, James Kennett, and George himself, never required a crater: an airburst over the two-kilometre-thick Laurentide Ice Sheet, comparable to Tunguska's 1908 blast that flattened 2,000 square kilometres without leaving a crater, explains the physical evidence at more than 50 sites across four continents, including nano diamonds, shocked quartz matching the standard used to validate the Ries impact crater in Germany, and a platinum spike first identified in Greenland ice cores.
The volcanic counter-hypothesis rests on two papers that disagree with each other on which eruption caused it, Locher C versus an unidentified Icelandic eruption, and neither has located matching tephra or ash to confirm a real event. George details a specific, checkable controversy: researcher Marc Young's rebuttal citing a whistleblower who provided the complete Hall's Cave dataset, revealing a missing sample with platinum concentration more than four times higher than anything in the published paper, sitting exactly where the boundary layer would be expected. He also notes the asymmetry in how each side has been treated: the Comet Research Group faced formal retraction of two papers in February 2026, while Sun and colleagues have offered no on-record response to Young's specific claim after nearly a year.
George's conclusion is deliberately unresolved: both hypotheses have real evidence and real gaps, and what would settle it is independent blind replication of the disputed proxies by labs with no stake in the outcome, a study he confirms is now underway, funded by a philanthropist, and we will keep you posted right here on the channel.
