The Younger Dryas has been known since the mid-twentieth century as a distinctive climatic phenomenon of Late Glacial Europe; but by the 1990s, it had gone global. Evidence across the northern hemisphere, along with a few hints from the southern hemisphere, seemed to indicate this was a widespread, abrupt, and possibly quite severe cold snap that ...

The Younger Dryas in the Eastern Mediterranean
Quaternary Science Reviews, 1995The Younger Dryas period is traced in pollen diagrams of the Eastern Mediterranean by means of radiocarbon dates. The biostratigraphy in terms of pollen assemblages is compared with the absolute time scale. The Younger Dryas as a pollen assemblage zone is at best vaguely visible in those parts that at present carry steppe or other open vegetation.

The mysterious onset of the Younger Dryas
Quaternary International, 2011Abstract The 1300-year-long Younger Dryas cold reversal (12,900–11,600 cal BP) is seen most clearly in Greenland ice cores. Contemporaneous changes of climate and environment in more southerly regions were variably expressed. The precise timing of the abrupt Younger Dryas onset is still uncertain. It was linked to a sudden increase in 14C manifest as

The Alleröd/Younger Dryas Boundary
1987From former cirque glaciers in western Norway, it is calculated that the summer (l.May to 30.September) temperature dropped 5–6°C during less than two centuries, probably within decades, at the Allerod/Younger Dryas transition, some 11,000 years ago. From the same data the Younger Dryas summer temperature is estimated to have been 8–10°C lower than at ...

Lake Agassiz during the Younger Dryas
Quaternary Research, 2013Lake Agassiz was ponded on the northward-sloping surface of the Hudson Bay and Arctic Ocean basins, as the Laurentide Ice Sheet retreated. The level of Lake Agassiz abruptly fell ~ 12.9 cal (11 14C) ka BP, exposing the lake floor over a large region for > 1000 yr.

Evidence of the younger dryas in Central America
Quaternary Science Reviews, 1995Abstract Three sites provide records that address whether the Younger Dryas was manifest in Central America. Marine records from Barbados and the Cariaco Basin are discussed, as well as possible climatic forcing mechanisms. Sequences from montane La Chonta Bog, Costa Rica, and lowland Lake Quexil, Guatemala, record a temperature decline of 1.5–2.5°C ...
