What caused Bolling allerod?
What caused Bolling allerod?
Causes. In recent years research tied the Bølling–Allerød warming to the release of heat from warm waters originating from the deep North Atlantic Ocean, possibly triggered by a strengthening of the Atlantic meridional overturning circulation (AMOC) at the time.
When did the Younger Dryas start?
between roughly 12,900 and 11,600 years ago
Younger Dryas, also called Younger Dryas stadial, 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 a Bolling allerod period?
A period of warm climate beginning abruptly approximately 14 700 years ago, following the end of the Pleistocene, and extending to approximately 12 700 years ago. This warm period ended with a return to cold conditions during the Younger Dryas.
What caused the Antarctic Cold Reversal?
Ancient sea ice loss spurred Antarctic cold reversal 15,000 years ago. June 22 (UPI) — A mysterious period of climate change, known as the Antarctic cold reversal, was triggered by the rapid loss of sea ice nearly 15,000 years ago, according to a study published Monday in the journal Nature Geoscience.
When’s the next ice age due?
Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1,500 years.
Was the Younger Dryas triggered by a flood?
It is widely believed that this cold event was triggered by a flood of fresh water that poured into the northern Atlantic (1) and disrupted the thermohaline ocean circulation (2).
When was the Antarctic Cold Reversal?
14,700 to 13,000 years ago
Antarctic ice cores show that a millennial-scale cooling event, the Antarctic Cold Reversal (14,700 to 13,000 years ago), interrupted the last deglaciation1,2,3.
