Аннотация: Oxygen isotope variations in ice wedges firstly used as indicators for winter temperature changes. 25 of yedoma exposures, from Yamal Peninsula to Chukotka, and 18 of middle Holocene ice wedges have been studied. Concept of the horizontal and vertical sampling of ice wedges for isotopic determinations is designed. The modern relationship between δ18O composition of ice-wedge ice and sum (total) winter temperatures is calculated and used as a base for reconstruction. For the first time created a map of the δ18O distribution of modern ice wedges formed during last 60-100 years for the whole territory of Siberia. For the first time created a maps of the total winter temperatures distribution for the whole territory of Siberia during three time intervals: 30-25 ka BP, 22-14 ka BP and 10-5 ka BP. Firstly it was shown that during the Late Pleistocene cryochron - 40-10 ka BP paleoclimate was stable throughout the territory of Siberia, and in the Holocene Optimum (10-5 ka BP) winter temperatures were even slightly lower today.
