The Arctic currently experiences a pronounced and likely unprecedented warming. This highly dynamic response on changes in climate forcing and the global impact of the Arctic water, carbon and energy balance make the Arctic a key region to study past, recent and future climate change on different spatial, temporal and seasonal scales. Ice-wedge isotopic composition records (δ18O, δD) from the Oyogos Yar coast (72.7°N, 143.5°E) in the Northeast Siberian Arctic that cover the past two millennia are presented. We discuss the chronological approaches as well as the paleoclimatic findings.
