Younger Dryas - The end of the Younger Dryas

The Younger Dryas stadial, named after the alpine / tundra wildflower Dryas octopetala, and also referred to as the Big Freeze [1], was a brief (approximately 1300 +/- 70year [1]) cold climate period following the Bölling/Allerød interstadial at the end of the Pleistocene, and preceding the Preboreal of the early Holocene. In Ireland, the period has been known as the Nahanagan Stadial, while in the U ...

Measurements of oxygen isotopes from the GISP2 ice core suggest the ending of the Younger Dryas took place over just 40 - 50 years in three discrete steps, each lasting five years. Other proxy data, such as dust concentration, and snow accumulation, suggest an even more rapid transition, requiring a ~7 °C warming in just a few years [2],[3],[6],[7], [8]. The end of the Younger Dryas has been dated to around 9600 BC (11550 calendar years BP, occurring at 10000 radiocarbon years BP, a "radiocarbon plateau") by a variety of methods, wit ...

Although the Younger Dryas had the greatest effect in Europe, it was noted throughout the world including: Replacement of forest in Scandinavia with glacial tundra (which is the habitat of the plant Dryas octopetala). Glaciation or increased snow in mountain ranges around the world. More dust in the atmosphere, originating from deserts in Asia. Drought in the Levant, perhaps motivating the Natufian culture to invent agriculture. The Huelmo/Mascardi Cold Reversal in the Southern Hemisphere began sligh ...
