Long-term temperature trends and tree growth in the Taymir region of northern Siberia
The northernmost conifers in the world are located well above the Arctic Circle in the Taymir region of northern Siberia and have been recording the thermal environment for centuries to millennia. Data from annual tree-ring widths are used
during the formation of older generation ice wedges were lower than Holocene winter temperatures, indicating that they developed in the Late Weichselian. The presence of syngenetic ice wedges strongly suggests that the coast of western Taymir was not ice
