Reconstruction of climate changes in East Siberia (Russia) from 1500 AD to the present based on tree-rings records

ABSTRACTThis paper describes variability in trends of tree growth at tree-line locations of the Kolar and East Sayan Ridges in the high latitudes of Eurasia (East Siberia), providing a wide regional comparison over a 500-year period. The study focuses on the nature of local and widespread tree-growth responses to the Little Ice Age and Recent Warming climate changes. We found that tree-growth in studied areas mainly depended on June temperatures. Changes in June temperature were more pronounced in the Kolar Ridge compared to the East Sayan Ridge. In general, summer temperature regimes were more unstable during the Recent Warming, compared to the Little Ice Age.
