Claim summary · not a verbatim quotation
Ice core samples find high levels of iridium in many areas from approximately 11,000 years ago.
The finding
What the evidence shows
Joe describes high iridium in ice cores as undeniable evidence for a Younger Dryas impact around 11,000 years ago. The 2013 GISP2 study found a platinum anomaly near the boundary around 12,800 years ago and explicitly no prominent iridium anomaly. Its authors considered an extraterrestrial source but could not positively identify it. That is distinct from proving a civilization-destroying impact.
