IMPLICATIONS OF MODULATING GLACIERS AND SNOW COVER IN MONGOLIA
Mongolia’s cryosphere (glaciers and snow cover) drives ecosystem services and in turn, supports emerging economies in the water-restricted country. However, as Mongolia experiences long-term drought conditions and an increase in annual air temperatures at twice the global rate, the potential adverse...

Mongolia’s cryosphere (glaciers and snow cover) drives ecosystem services and in turn, supports emerging economies in the water-restricted country. However, as Mongolia experiences long-term drought conditions and an increase in annual air temperatures at twice the global rate, the potential adverse effects of the changing cryosphere during a period of climate uncertainty will have cascading implications to water availability and economic development.
