Complex use of the geochemical features of bottom deposits and pollen records for paleoclimate reconstructions (with lake Teletskoe, Altai Republic, as an example)

The delayed response of taiga and steppe biomes to climate changes has been detected with Lake Teletskoe as an example. A paleoreconstruction has been made on the basis of the integral use of geochemical features of bottom sediments and pollen records. It showed 100-year mean temperatures to a time depth of 4000 years with the isolation of the assumed boundaries of climate reconstructions in the 14th and 4th centuries B.C. and the 13th and 20th centuries A.D. A comparison of the temperature reconstruction for Lake Teletskoe with the temperature chronologies for the Northern Hemisphere and northeastern Europe has been carried out.
