The Younger Dryas impact theory suggests a catastrophic event around 12,800 years ago abruptly ended a warming trend, plunging Earth back into glacial conditions for 1,300 years. This event may have triggered mass extinctions, wiped out megafauna, and reset early civilizations, reshaping the planet’s history. | The Randall Carlson

The Younger Dryas impact theory points to a cataclysm 12,000 years ago... an event powerful enough to end the Ice Age, wipe out entire species, and reset human civilization. After a period of natural warming driven by Milanković cycles, the planet suddenly plunged back into deep glacial cold for 1300 years. Something far more abrupt than orbital geometry had to be involved. | The Randall Carlson
