THE warming at the end of the last glaciation was characterized by a series of abrupt returns to glacial climate, the best-known of which is the Younger Dryas event1. Oxygen isotope data from Greenland ice cores2–4 suggest that the Younger Dryas ended abruptly, over a period of about 50 years; 1. Bard, E. & Broecker, W.

Nanodiamonds, such as these in the black layer of sediment at the Murray Springs archaeological site in Arizona, may explain the extinction of large animals, the disappearance of the Clovis culture and the climate change of an epoch known as the Younger Dryas. Scientists have long blamed climate change for the extinctions,

The Younger Dryas (YD) was the most significant rapid climate change event that occurred during the last deglaciation of the North Atlantic region. Previous ice core studies have focused on the abrupt termination of this event [ Dansgaard et al., 1989] because this transition marks the end of the last major climate...

5.3.2.1. The Younger Dryas Event The Younger Dryas cooling event may have been caused by meltwater-induced changes in the atmosphere-ocean circulation. During the early stages of deglaciation, Unfortunately, evidence of CO2 reduction during the Younger Dryas (Stauffer et al., 1985) remains inconclusive.
