  • Younger Dryas | Definition, Causes, Termination | Britannica
    Younger Dryas, cool period between roughly 12,900 and 11,600 years ago that disrupted the prevailing warming trend occurring in the Northern Hemisphere at the end of the Pleistocene Epoch (which lasted from 2 6 million to 11,700 years ago)
  • What caused the Younger Dryas frigid spell: case closed?
    At 12,870 years ago the warming and sea-level rise were reversed for 1,170 years in the Northern Hemisphere: an episode of near-full glacial conditions known as the Younger Dryas (YD)
  • The Younger Dryas Period: the Last Time the Earth was Changed
    Our climate is changing rapidly, but not for the first time There may be lessons we can learn from the last period of rapid change, known as the Younger Dryas

  • The Younger Dryas Period: A Sudden Global Freeze
    The Younger Dryas period left a mark on Earth’s ecosystems, influencing plant and animal life The event is named after Dryas octopetala, an arctic wildflower whose pollen became prevalent in European sediment layers, indicating a widespread return of cold, tundra-like landscapes
  • Abrupt Climate Change - the Younger Dryas - Columbia University
    Dryas octopetala is a flower in the Rosaceae family, typical of cold, open, Arctic environments In the nineteenth century, the leaves and fruits of this plant were found in Scandinavia layers atop tree macrofossils, indicating that an abrupt climate shift to cold conditions took place
