Melting glaciers

Greenland's ice sheet is the second largest ice mass on Earth after the Antarctic ice sheet. It contains 10 percent of the world's glacial ice, and it's melting at a whopping 8000 tons per second.

More than two-thirds of Earth's fresh water is stored in glaciers. The loss of all the ice from melting glaciers will affect the global water cycle and considerably impact water supply and quality, energy generation, and incidences of extreme weather.
