On Thin Ice

Greenland is the world’s biggest Island where around 80 percent of the surface is covered with ice. The ice in the current ice sheet is as old as 110,000 years. Positioned in the Arctic, Greenland is especially vulnerable to climate change and has experienced record melting in recent years and is likely to contribute substantially to sea level rise as well as to possible changes in ocean circulation in the future. Around 10 percent of the Earth is covered with glacial ice, including glaciers, ice caps, and the ice sheets of Greenland and Antarctica. The glaciers around the wold store about 75 percent of the world’s fresh water and if all land ice melted, sea level would rise approximately 70 meters worldwide.
