Younger Dryas - Wikipedia The Younger Dryas is named after the alpine – tundra wildflower Dryas octopetala, because its fossils are abundant in the European (particularly Scandinavian) sediments dating to this timeframe
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 Is the Younger Dryas and Why Does It Matter? The Younger Dryas was a sudden cold snap 12,900 years ago that reshaped ecosystems, wiped out megafauna, and may have redirected human civilization
The Big Freeze: Rapid Cooling During the Younger Dryas It was named after the vast quantities of pollen from tundra flower species, Dryas octopetala, found in sediment deposited at the time It’s also called the Big Freeze for obvious reasons
The Younger Dryas What caused the Younger Dryas? The Younger Dryas occurred during the transition from the last glacial period into the present interglacial (the Holocene) During this time, the North American, or Laurentide, ice sheet was rapidly melting and adding freshwater to the ocean
Younger Dryas Research Home This shows that the magnitude of fresh water forcing is of importance to reconstructing the Younger Dryas climate The simulation without freshwater forcing is comparable to the present-day ocean circulation
Understanding the Younger Dryas: Causes and Characteristics Dryas octopetala, known by names such as mountain avens and white dryas, is a flower associated with Arctic and high-elevation areas It thrives in cold climates and was widespread during glacial periods but retracted significantly during interglacials and interstadials
Younger Dryas | Earth and Atmospheric Sciences - EBSCO The Younger Dryas, occurring 12,900 to 11,600 years ago, was a well-defined climatic event during which cool temperatures returned and ice sheets reformed The term “Dryas” denotes the arctic-alpine herb, Dryas octopetala
