Greenland Ice Sheet – Greenland
The Ilulissat Icefjord was declared a UNESCO World Heritage Site in 2004. The majority of Greenland’s Ice Sheet is inaccessible, providing a natural form of protection.
The Greenland Ice Sheet is the second largest body of ice in the world and comprises an area of nearly 650,000 square miles. Its ice ranges between 1-2 miles thick and is estimated that some is 100,000 years old. The transition from green land to a large mass covered in ice began about 3 million years ago as a result of a decline within the area’s atmospheric carbon dioxide.
The ice sheet, consisting of layers of compressed snow from the past 100,000 years, contains invaluable records of past climates and attracts climatologists and researchers world-wide. Many scientists who study ice depletion in Greenland consider that an increase in temperature of two or three degrees Celsius would result in a complete melting of Greenland’s ice, raising global sea levels by 24 feet.
