Аннотация доклада:
In this contribution we seek to summarize Holocene ice-wedge 18О based temperature information from the Northeast Siberian Arctic. We consider the stable-isotope composition of wedge ice, ice-wedge dating and chronological approaches as well as the stratigraphic context of the studied ice wedges in terms of suitability for reconstruction of high-quality records. Our Mid to Late Holocene ice-wedge _18O records show a marked variability with long-term increasing trends and an unprecedented recent maximum. The derived winter temperature records are discussed considering other Arctic paleoclimate records, climate forcing factors as well as climate-model results
