Abstract
A critical review on climate changes and g roundwater has been made from the point of view of global studies on groundwater. Groundwater recharge, groundwater discharge, effects of sea level rise, groundwater storage, effects on groundwater quality and subsurface temperature, and methodologies have been discussed. International projects such as GRAPHIC (Groundwater Resources Assessment under the Pressures of Humanity and Climate Changes) project are also introduced for global studies on groundwater.
