Abrupt millennial climatic terrestrial changes from western European eolian records during the last glaciation?

High expectation has been focussed on the massive iceberg discharges in the North Atlantic, Heinrich events, during the last glaciation, and their worldwide terrestrial counterparts. However these events are particular episodes among more regular cyclic events named Dansgaard-Oeschger events in ice-cores or Bond cycles in marine cores. Here we examine grain-size, d13C, and susceptibility data from Nussloch, one of the most complete West European eolian sequence. These indices indicate that, at least during the 19-31 kyr interval which is highly documented in this terrestrial series, millennial variations of the environment (moisture and vegetation) associated to oscillations in the wind dynamics match the low-high dust content in the atmosphere over Greenland. Height soil-loess successions repeat during this interval as well. Our study thus shows that the abrupt climatic changes expressed by the cyclic Dansgaard-Oeschger events are at least either recorded in the west European loess sequences. This implies a global atmospheric dynamics linking, not only temperature, but also the dust deposition over Greenland and Europe.
