Entire Ice Sheet of Greenland About to Disappear From the Earth

A panel of scientists told Congress the entire ice mass of Greenland will disappear from the world map if temperatures rise by as little as 2C –3.6 degrees Fahrenheit, with severe consequences for the rest of the world.The fall-out would be felt thousands of miles away from the Arctic, unleashing a global sea level rise of 23 feet. Low-lying cities such as New Orleans would vanish.

The Greenland ice sheet  is a vast body of ice covering  660,235 sq mi, roughly 80% of the surface of Greenland. It is the second largest ice body in the World, after the Antarctic Ice Sheet. The ice sheet is almost 1,500 mi long in a north-south direction, and its greatest width is 680 mi at a latitude of 77°N, near its northern margin.  The thickness is generally more than 1.24 mi; 1.86 mi at its thickest point. It is not the only ice mass of Greenland – isolated glaciers and small ice caps cover between  29,344 and 38,610 sq mi around the periphery. The ice in the current ice sheet is as old as 110,000 years.

 Scientists believe  global warming may be about to push the ice sheet over a threshold where the entire ice sheet will melt in less than a hundred or so years. If the entire 683,751 cu mi of ice were to melt, it would lead to a global sea level rise. This would inundate most coastal cities in the World and remove several small island countries from the face of Earth, since island nations such as Tuvalu and Maldives have a maximum altitude below or just above this number.

 'Goodbye  World,' as we know it. 'Hello Seaworld.'
