Abstract
Alpine and arctic karst regions arc characterized by low temperatures and generally low amounts of vegetation and CO2. Most are also associated with past or present glaciation. Despite the greater solubility of CO2 at low temperatures, the reduced rates of solution and vegetal production of CO2 make the average chemical denudation rate in arctic regions less than that of warmer humid regions. Chemical denudation rates in alpine karst exceed the average for other humid karst areas only where the amount of precipitation is also greater. The main value of arctic and alpine karst studies is the clear evidence they provide for past climate changes and glaciation. Solutional caves can also provide a subsurface view of the hydrology of existing glaciers.
