Sea level rise abnormally

Global sea levels are rising at an unusual rate as the Greenland ice sheet begins to melt after a sustained effort.

The temperature in the area is warming, leading to a level of melting in the level of concern in the Greenland Northeast.

According to an international team of experts, the ice shelf has lost about 10 billion tons of ice each year from April 2003 to April 2012.

Greenland is said to be one of the 'powers' that contribute to sea level rise over the past 20 years, accounting for 0.5mm out of 3.2mm of sea level rise each year.

Earlier measurements and satellite images showed that the Northeast Greenland ice sheet seemed to remain stable for 25 years, until 2003, according to AFP.

Professor Jonathan Bamber of the University of Bristol (UK) said that this time the group has expanded the survey to more than 600km deep on the ice, the farthest level ever studied.

The main tool to help record changes in Greenland is a system of 50 GPS sensors located along the Greenland coast.
