Outline of Final Research Achievements

Millennial-scale climate variability and its biological response during the early to the mid last glacial period is well documented from marine and continental records. Here we reconstruct hydrological variability (river input and the chemical weathering intensity) using two independent sedimentological and geochemical proxies at Lake Baikal in southern Siberia. We find that the millennial-scale hydrological variability during the late last glacial period (31-11.5 cal ka BP) is associated with solar activity changes, with wet (dry) climate conditions in the Siberian region corresponding to solar maxima (minima). Millennial-scale biological response to hydrological change resulting from solar activity during the last glacial period is also observed. Our results indicate that the solar-induced millennial-scale hydroclimate variability appears to control Eurasian biological change during the late last glacial period.
