jan 1, 12000 BC - Yonder Dryas, 12k BCE
Description:
The Younger Dryas, which occurred circa 12,900 to 11,700 years BP, was a return to glacial conditions which temporarily reversed the gradual climatic warming after the Last Glacial Maximum (LGM), which lasted from circa 27,000 to 20,000 years BP. The Younger Dryas was the last stage of the Pleistocene epoch that spanned from 2,580,000 to 11,700 years BP and it preceded the current, warmer Holocene epoch. The Younger Dryas was the most severe and longest-lasting of several interruptions to the warming of the Earth's climate, and it was preceded by the Late Glacial Interstadial, an interval of relative warmth that lasted from 14,670 to 12,900 BP.The Younger Dryas did not affect the climate equally worldwide, but the average temperature changed drastically. For example, slight warming occurred in the Southern Hemisphere and some areas of the Northern Hemisphere, such as southeastern North America.
