Allerød oscillation
The Allerød oscillation (Danish: Allerødtiden) was a warm and moist global interstadial that occurred c.13,900 to 12,900 BP. It was preceded by the Older Dryas and followed by the Younger Dryas cold periods. The Allerød was nearly at the end of the Last Glacial Period. It raised temperatures in the northern Atlantic region to almost present-day levels, before they declined again in the Younger Dryas, which was followed by the present warm Holocene.

The Allerød period was named after a type site in Furesø Municipality in Sjælland, Denmark (near Copenhagen), where deposits created during the period were first identified in work published in 1901 by Hartz and Milthers. This Blytt–Sernander period corresponds to Pollen zone II.
