Rapid greening of tundra discovered in large area of West Siberia

04 Jun 2012: Rapid Greening of Tundra Discovered in Large Area of West Siberia Across a large area of western Siberia, shrubs are rapidly growing into trees more than six feet tall , a process that is expected to further increase temperatures in this rapidly warming part of the Arctic, according to a new study. Relying on satellite images and fieldwork, scientists from Oxford Oxford University University and Finland found that in 8 to 15 percent of a 36,000-square-mile region in western Siberia, willow and alder shrubs had turned into trees over the last 30 to 40 years as temperatures have climbed. Oxford scientists said their research showed that the growth of shrubs could be an even more important factor in the greening of the tundra than the migration of trees northward from the boreal forest. The rapid growth of trees is expected to further warm the Arctic for two reas...
