Glaciers in Greenland can raise global sea levels by about 1.3 meters



Glaciers in Greenland melt faster than expected which make raising sea levels.

New research warns that the three largest glaciers in Greenland could melt faster than previously predicted.  These glaciers hold water that can raise global sea levels by about 1.3 meters.

According to AFP news agency, research released on Nov 17 showed that the three largest glaciers in Greenland including Jakobshavn Isbrae, Kangerlussuaq and Helheim - with melting ice is capable of raising the global sea level to about 1.3  meter - is melting faster than worst forecast.

 A team of researchers based in Denmark and England used past images and a host of other data to estimate the amount of ice lost from these glaciers in the 20th century.

 They found that the Jakobshavn Isbrae glacier lost more than 1,500 billion tons of ice between 1880 and 2012, while the Kangerlussuaq and Helheim rivers lost 1,400 billion tons and 31 billion tons of ice between 1900 and 2012, respectively.

 Melting ice sheets have caused global sea levels to rise by more than 8mm, the team said.

 Mr. Shfaqat Abbas Khan, a researcher at the Technical University of Denmark, told AFP News Agency: "Historical measurements in the 19th and 20th centuries may not show important information that could lead to significant improvement of our future forecasts ".

 The United Nations Intergovernmental Panel on Climate Change (IPCC) forecasts global sea levels will rise by 30-100cm by 2100, depending on emissions.

Meanwhile, according to a study in Nature published in September, if the greenhouse gas emissions continue not to decrease, the Greenland ice sheets will be discharged into the sea by about 36,000 billion tons this century,  enough to raise the global sea level by 10cm.
