Ice sheets in Greenland and Antarctica were to melt with a faster acceleration than previously thought. This was revealed by the latest findings by the United States space agency NASA.As quoted from Physorg sites, which use traditional research satellite imagery was found that the Greenland and Antarctic ice sheet thinned three times faster than the depletion that occurs in glaciers and icebergs.
Ice sheets in Greenland and Antarctic mass loss of as much as 475 gigatons each year. One gigaton is equivalent to one billion metric tons. This volume is enough to raise world sea levels to average as high as 1.3 millimeters per year.
The study itself, using two different measurement techniques, ie using data from interferometric synthetic aperture radar and a regional atmospheric climate model data from the Utrecht University, as well as observations from NASA satellite data / Gravity Recovery and Climate Experiment (Grace), Germany for eight years.
