Scientists are fairly certain that the last two abrupt coolings seen the Greenland ice core, the "Younger Dryas" event and the "8200 years before present" event (Figure 1), both occurred when huge North American glacial melt-water lakes flooded down the St. Lawrence River into the North Atlantic when the ice dams restraining the lakes broke.

The Younger Dryas cold event, a rapid reversion to glacial climate conditions at the Pleistocene‐Holocene transition, has generally been attributed to the release of meltwater from the Laurentide Ice Sheet to the North Atlantic or Arctic oceans.

URL consultato il 9 giugno 2009 (archiviato dall'url originale il 23 agosto 2007). Since 1916 and the onset and then the refinement of pollen analytical techniques and a steadily-growing number of pollen diagrams, palynologists have concluded that the Younger Dryas was a distinct period of vegetational change in large parts of Europe during which vegetation of a warmer climate was replaced by that of a generally cold climate, a glacial plant succession that often contained Dryas octopetala. The Greenland ice-core records provide an exceptionally clear picture of many aspects of abrupt climate changes, and particularly of those associated with the Younger Dryas event, as reviewed here. The ice cores show that the end of the Younger Dryas interval involved: 5–10°C warming and a doubling of snow accumulation in central Greenland; a large drop in wind-blown materials, indicating reduced wind speed and other changes in distant source regions or between source regions and Greenland; and a large increase in methane, indicating expansion of global wetlands, probably … The Younger Dryas is clearly recorded in Greenland ice cores (Fig. Copyright © 2021 Elsevier B.V. or its licensors or contributors.
