Аннотация: A major focus of the study described here is an attempt to reveal the nature of local and any widespread tree-growth responses to the recent warming seen in the instrumental observations. Namely, this chapter discusses spatial variation in the trends of radial tree-ring growth in Siberia and the Far East during different periods of the 18th to 20th centuries. That distribution of trends is compared with spatial NDVI trends and temperature changes in the northern hemisphere over the past 20 years. A new classification approach is described to associate different spatial-temporal samples of tree-ring trends with recent tendencies of Siberian vegetation activity. Obtained shot-term tree-growth tendencies for the eighteenth twentieth centuries are characterized by a common decrease of trend values from West to East with highest values for southern latitudes of Siberia and comparable to NDVI trends. But a recent spatial sample of tree-growth trend is described by highest variation for the last 250 years which can be explained by the most significant recent warming in the context of 2,000 years.
