The Antarctic
ice sheet, which is 1.5 miles thick in some places, contains over 90
percent of the world's fresh
water.
But scientists do not know how global warming may affect Earth's two major
ice sheets, in Greenland and Antarctica, which hold 77
percent of the world's fresh
water — enough to potentially raise the sea level approximately 225 feet (70 meters).
Using climate models, Radic found that these smaller mountain glaciers and
ice caps may contribute more than 4.5 inches (12 centimeters) to world sea level rise by the beginning of the next century, even though they contain less than one
percent of all
water on Earth bound in glacier
ice.
Ninety - eight
percent of the GOES grid points had
ice water paths no greater than 60 g m − 2, as compared with 74 % for MM5.

percent of MM5 points had
ice water content > 200 g m − 2, as compared with 0.07 % for GOES retrievals.
(A third of summer sea
ice in the Arctic is gone, the oceans are 30
percent more acidic, and since warm air holds more
water vapor than cold, the atmosphere over the oceans is a shocking five
percent wetter, loading the dice for devastating floods.)
«
Water is seen on part of the glacial
ice sheet that covers about 80

97
percent of the
water on Earth is salt
water, contained in the planet's oceans, seas, and inland salt
water bodies, 2
percent of it (fresh
water) is locked in the polar

percent is the fresh
water we use everyday.
