The Greenland ice sheet is the second biggest glacier in the world. It is a glacier that covers 80 percent of the country of Greenland. The total ice area of the ice sheet is 1.799 million square kilometers and the total ice volume is 2.99 million cubic kilometers. The thickest ice is 3,488 meters. Greenland actually used to be green and warm before being covered with ice. Ice started to form and cover Greenland about 3 million years ago. The ice sheet has been there for the past 2 to 3 million years. Scientists came to the conclusion that the ice sheet that formed was due to the changes within the area’s atmospheric carbon dioxide. The area had high levels of carbon dioxide and climate change caused it to drop low enough to allow the ice sheet to begin forming. The ice of the ice sheet is both new and old because the ice has been recycled many times due to melting and refreezing. The Greenland ice sheet is still there today and is part of the Kingdom of Denmark. The glacier is still occuring over Greenland and it is currently slowly melting due to global warming and climate change. The sea levels are slowly rising due to the ice melting into the ocean. It is predicted that by the year 2100 that 5 percent of the Greenland ice sheet will melt off thus making the sea levels rise up to 21 inches. If all the ice of the ice sheet were to melt then the ocean’s sea level would be raised by 24 feet. In early September of 2017, the southern part of the ice sheet melted by 15 percent due to rising temperatures. After 3 days, the temperature returned back to normal. The type of glacier that covers Greenland is an ice sheet. An ice sheet is a mass of glacial ice that covers a huge part of land. Ice sheets form when snowfall does not completely melt and the layers of snow slowly pile up over time. The snow falls into layers that thicken into ice when new snow compresses with old snow that is in an older layer. An ice sheet remains stable as long as it continues to gain more ice and snow than it can melt off into the ocean. Greenland and the Antarctic ice sheet contain 99 percent of frozen freshwater on Earth. Another name for ice sheet is ice cap. Greenland used to be a land that was capable of allowing life that could live in a warmer climate, but after the ice sheet formed that wasn’t possible anymore. The country is now more suitable for life that would prefer to live in  a much colder climate such as polar bears, walruses, and reindeer. I picked this particular glacier because it looked interesting. I have always wondered why the country Greenland was called Greenland even though it was covered in ice. Doing research on the ice sheet has increased my knowledge on the subject.
