Abstract
The first late-glacial lake sediments found in Greenland were analyzed
with respect to a variety of environmental variables. The analyzed
sequence covers the time span between 14 400 and 10 500 calendar yr
B.P., and the data imply that the conditions in southernmost Greenland
during the Younger Dryas stadial, 12 800–11 550 calendar yr B.P., were
characterized by an arid climate with cold winters and mild summers,
preceded by humid conditions with cooler summers. Climate models imply
that such an anomaly may be explained by local climatic phenomenon
caused by high insolation and Föhn effects. It shows that regional and
local variations of Younger Dryas summer conditions in the North
Atlantic region may have been larger than previously found from proxy
data and modeling experiments.
