How much of Earth’s freshwater is stored in ice sheets and glaciers?

Ice sheets and glaciers are the primary reservoirs of Earth's freshwater. Together, they contain approximately 69 percent of all the freshwater found on the planet.1

Other estimates indicate that glacier ice stores about three-fourths of the world's total freshwater. When considering the total volume of water on Earth, ice caps, glaciers, and permanent snow account for roughly 1.74 percent of all water, while approximately 72.5 percent of the planet's total freshwater is currently frozen. The vast majority of this glacier ice—about 99 percent—is held within the Antarctic and Greenland ice sheets.2341
