Allerød Oscillation

From Freepedia

The Allerød period is a part of a temperature oscillation towards the end of the last Ice Age in Europe, where temperatures in the Northern Atlantic region rose from glacial to almost present day level in the Bølling and Allerød periods and returned to glacial levels in the Younger Dryas period before the climate warmed and the present interglacial period started. Many ages estimates of Allerød can be found, but Greenland ice cores date Allerød to roughly 14,000 - 13,000 years before present. It is named after the type site of Allerød in Sjælland in Denmark where deposits created during the period were first identified in 1901 by Hartz and Milthers.

It is a substage of the Devensian Late Glacial Period and a similar weather change also took place in North America where it is known as the Two Creeks Interval. It is sometimes called the Windermere Interstadial in Britain, and the Woodgrange Interstadial in Ireland.
