      abstract     = {To gain insights into the mechanisms of abrupt climate
                      change within interglacials, we have examined the
                      characteristics and spatial extent of a prominent,
                      climatically induced vegetation setback during the
                      Holsteinian interglacial (Marine Isotope Stage 11c). Based
                      on analyses of pollen and varves of lake sediments from
                      Dethlingen (northern Germany), this climatic oscillation,
                      here termed the "Older Holsteinian Oscillation" (OHO),
                      lasted 220 years. It can be subdivided into a 90-year-long
                      decline of temperate tree taxa associated with an expansion
                      of Pinus and herbs, and a 130-year-long recovery phase
                      marked by the expansion of Betula and Alnus, and the
                      subsequent recovery of temperate trees. The climate-induced
                      nature of the OHO is corroborated by changes in diatom
                      assemblages and delta O-18 measured on biogenic silica
                      indicating an impact on the aquatic ecosystem of the
                      Dethlingen paleolake. The OHO is widely documented in pollen
                      records from Europe north of 50 degrees latitude and is
                      characterized by boreal climate conditions with cold winters
                      from the British Isles to Poland, with a gradient of
                      decreasing temperature and moisture availability, and
                      increased continentality towards eastern Europe. This
                      pattern points to a weakened influence of the westerlies
                      and/or a stronger influence of the Siberian High. A
                      comparison of the OHO with the 8.2 ka event of the Holocene
                      reveals close similarities regarding the imprint on
                      terrestrial ecosystems and the interglacial boundary
                      conditions. Hence, in analogy to the 8.2 ka event, a
                      transient, meltwater-induced slowdown of the North Atlantic
                      Deep Water formation appears as a plausible trigger
                      mechanism for the OHO. If correct, meltwater release into
                      the North Atlantic may be a more common agent of abrupt
                      climate change during interglacials than previously thought.
                      We conclude that meltwater-induced climate setbacks during
                      interglacials preferentially occurred when low rates of
                      summer insolation increase during the preceding terminations
                      facilitated the persistence of large-scale continental
                      ice-sheets well into the interglacials. (C) 2012 Elsevier
