Eustatic sea level rises threaten to contaminate groundwater, affecting drinking water and agriculture in coastal zones. Increased evaporation will reduce the effectiveness of reservoirs. Increased extreme weather means more water falls on hardened ground unable to absorb it - leading to flash floods instead of a replenishment of soil moisture or groundwater levels. In some areas, shrinking glaciers threaten the water supply.
Higher temperatures will also increase the demand for water for cooling purposes.
In the Sahel, there has been on average a 25% decrease in annual rainfall over the past 30 years
