Younger Dryas: The 12,800-Year-Old Layer and the Story of a World Reset
Around 12,800 years ago, Earth was warming after the Ice Age when the climate of the Northern Hemisphere reversed sharply. Temperatures in Greenland dropped, ice returned to many regions, growing seasons shrank, and cold conditions lasted roughly 1,200 to 1,300 years. Geologists call this period the Younger Dryas. It is not a legend: ice cores, pollen, lake sediment, and isotope records all preserve the climate reve…
