Changes in hydrogeologic regimes in permafrost regions due to climatic change

The general and specific effects of predicted climate change on groundwater systems in permafrost regions are summarized. Besides a general decrease in the thickness and areal distribution of permafrost, a large unfrozen near‐surface aquifer with perennial groundwater flow might develop. Recharge an...
