Patterns of frozen ground formation accompanying recent climate changes

Abstract

Beginning in the mid‐1960s a universal air temperature increase has been observed in the North. The warming of the upper horizons of the cryolithozone, recorded at observation stations during the last 15–20 years, in some cases is related to an increase in air temperature, but in others to an increase in snow depth. A scenario of moderate climate warming in northern Russia by 2020–2025, which will not result in a substantial restructuring of frozen ground conditions, is examined.
