- Аннотация: Ice wedges, as they are formed by snow melt, have a direct connection to the atmosphere and hence, are excellent recorders of past climate conditions, specifically of the winter season. However, quite a few Radiocarbon dates were needed to be able to use ice wedges as climate archives in more than a millennial-scale resolution. Moreover, a bit of luck was necessary to identify three key study sites, one in Barrow, Alaska, one in the Lena Delta, and a third at the Siberian Oyogos Yar coast that allowed for a precise up to sub-centennial scale 14C-dated Holocene and Late Pleistocene winter climate reconstruction. Understanding winter temperature change is of particular importance as the current Arctic warming is strongest in winter.
