AB: Results of an estimation of deviations of river runoff from their modern values within the largest rivers of Russian plain (Volga, Don, Dnieper) and Siberia (Lena) observed during the period of the Late Atlantic Optimum of the Holocene (5-6 thousand years ago) and probable at global climate warming in the XXI century caused by growth of atmospheric content of greenhouse gases of an anthropogenic origin are presented. A scenarios of climatic changes are based on results of experiments on global models of the general circulation of atmosphere and ocean, included in the international programs of comparison of results of paleoclimate modeling (Paleoclimate Modeling Intercomparison Project – PIMP) and future climate (Intergovernmental Group of Experts on Climate Change – IPCC) have been used. For estimation of hydrological changes macroscale model of monthly water balance developed in Institute of Geography of the Russian Academy of Science (Georgiadi, Milyukova, 2000; 2002; 2006) especially for study of hydrological consequences of global climatic changes in large river basins is used. Research was executed at support of Russian Fund on Basic Research 07-05-12085-ofi and 05-05-64499a.
