Abstract
The delayed response of taiga and steppe biomes to climatic changes was detected on the example of Lake Teletskoye. On the basis of the complex use of geochemical features of bottom sediments and pollen records a paleoreconstruction was made. It showed average 100-year temperatures at the depth of 4000 years with the isolation of the assumed boundaries of climatic reconstructions in XIV, IV centuries B.C. and XIII, XX centuries A.D. The comparison between temperature reconstruction for Lake Teletskoe with temperature time series for the Northern hemisphere and North-Eastern Europe was carried out.
