It was demonstrated that the studied ice wedges located 2000 km apart were formed during the last 2-3.5 ka and continue to grow at present. Variations of δ18O values of the ice of both ice wedges do not exceed 2-3.5‰. Based on the oxygen isotope variations is has been calculated that mean winter air temperatures did not change by more than 3oC during the Late Holocene.</p></abstract><kwd-group xml:lang="en"><kwd>permafrost</kwd><kwd>oxygen isotopes</kwd><kwd>14С-dating</kwd><kwd>ice wedge</kwd><kwd>winter palaeotemperatures</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Buntgen U., Esper A.J., Frank D.C., Nicolussi K., Schmidhalter M.
