Palaeotemperature reconstruction for the period of 20−18 ka BP in Siberia is based on δ¹⁸O analysis and ¹⁴C dating of large syngenetic ice wedges of yedoma exposures from Yamal Peninsula to Chukotka. The modern relationship between δ¹⁸O composition of ice-wedge ice and winter temperature reveals Pal...
