ИСТИНА

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. The high-resolution Akademii Nauk 18O ice core record (Severnaya Zemlya) proves the Late Holocene cooling trend and the unprecedented warming after 1800. It shows neither a pronounced Medieval Climate Anomaly nor a Little Ice Age but gives evidence of several abrupt warming and cooling events in the last centuries. These are probably related to the internal variability of the Arctic climate system, i.e. atmosphere-sea ice feedbacks in the Barents and Kara seas region.
