Exogenous Challenge in Yakutian Permafrost Areas: Analysis and Forecast
Abstract The paper discusses exogenous processes and dangers associated with their intensification on the plains and in the mountains of Yakutia in the XXI century. It has been established that these processes result from natural and climatic anomalies caused by changes in the climate. The first wav...
