Greenland ice sheet is the single largest body of freshwater ice in the Northern Hemisphere, covering roughly 80% of the surface of Greenland. Second in size after Antarctic ice sheet, Greenland ice sheet extends about 1.7 million square kilometers (656,000 square miles) – three times the size of US state of Texas. Recently, researches carried on the Northern ice sheet show that it could be more vulnerable to the global temperature rise, than previously estimated. According to scientists, the ice sheet contains enough water volume to raise sea level by 7 meters, putting at risks many coastal cities. Learn more about Greenland ice sheet, its history, global warming impact as well as the effects of its potential melting – in this book.
