Thawing Permafrost: The Speed of Coastal Erosion in Eastern Siberia Has Nearly Doubled


Oct. 29, 2013 — The high cliffs of Eastern Siberia -- which mainly consist of permafrost -- continue to erode at an ever quickening pace. This is the conclusion which scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research have reached after their evaluation of data and aerial photographs of the coastal regions for the last 40 years. According to the researchers, the reasons for this increasing erosion are rising summer temperatures in the Russian permafrost regions as well the retreat of the Arctic sea ice. This coastal protection recedes more and more on an annual basis. As a result, waves undermine the shores.
