Did You Know: Glaciers & Ice Sheet Hold 69% Off World’s Freshwater

A glacier can vary in length from the equal of a football field to extra than 100 miles. They are formed because of snowflakes over a long duration of time. New layers of snow appear every winter, creating the glacier huger and denser.

Glacial ice often occurs blue when it has become very thick and free of bubbles. Years of contraction slowly make the ice thicker over time, forcing out the tiny air pockets between the crystals.
When glacier ice becomes much dense, the ice consumes a small quantity of red light, leaving a bluish shade in the reflected light, which is what we observe. When the glacier ice appears white, that usually implies that there are several tiny air bubbles yet in the ice.

In Washington State, which is the state with the largest area of glaciers in the adjacent United States, melting glaciers contribute 1.8 trillion liters of water every summer season.

Antarctica’s Lambert glacier is the largest glacier on the earth. It is 60 miles broad and about 270 miles tall and is named after, former Australian director of national mapping, Bruce P Lambert. who enabled chart out the area during the 1950s.

Glaciers comprise approximately 69 percent of the world’s fresh water supply. In comparison lakes, streams, marshes, and related bodies can only claim a combined 0.3 percent water.

If every glacier and ice sheet on Earth unexpectedly melts, then global sea levels would increase by over 260 feet. Glaciers over the world have been melting for at least the last 50 years, and the proportion of melting is speeding up. Many glaciers in Alaska and other portions of the US have diminished dramatically.
