Ice Age return, comet impact hypothesis, and the catastrophe that may have erased an advanced civilization 12,800 years ago.
The Younger Dryas is one of the most dramatic climate events in Earth's recent history — a sudden return to Ice Age conditions approximately 12,800 years ago that lasted about 1,200 years. Its cause and consequences remain intensely debated. ## What Was the Younger Dryas? Between roughly 12,800 and 11,600 years ago, global temperatures plunged suddenly after a period of warming following the Last Glacial Maximum. In the Northern Hemisphere, temperatures dropped by 7-8 degrees Celsius within decades — possibly within a single human lifetime. The Younger Dryas takes its name from Dryas...
