The Arctic currently experiences a pronounced warming. This highly dynamic response on changes in climate forcing and corresponding feedbacks and the global impact of the Arctic water, carbon and energy balance make the Arctic a key region to study past and future climate changes. Recent proxy-based Arctic-wide temperature reconstructions exhibit long-term cooling trends over the last two millennia that have been reversed by the ongoing Arctic warming. However, most records are based on proxies that record summer information. Hence, the reconstructions are assumed to be seasonally biased towards the summer. Moreover, there exist only a few records from the Russian Arctic. Consequently, this region is significantly underrepresented in Arctic-wide reconstructions and a comprehensive picture of Arctic climate variability is challenging. Here we present glacier and ground ice records from the Russian Arctic that are related to the research project “Eurasian Arctic Ice 4k” funded by the German Research Foundation. They add valuable information for a better spatial and seasonal understanding of Holocene climate variability in the Arctic.
