Global sea levels have risen 0.55 inches since 2003 due to ice melt in Antarctica and Greenland driven by climate change according to new data measurements from several NASA satellites.
Scientists found that Greenland's ice sheet lost an average of 200 gigatons of ice per year and Antarctica's ice sheet lost an average of 118 gigatons of ice per year. One gigaton of ice can fill 400,000 Olympic-sized swimming pools.

Last year, Greenland's ice sheet, the biggest in the world, contributed to a sea level rise of about 1.5 millimeters in adriven by hotter temperatures. The country has seen a significant amount of coastal glacier thinning, with some glaciers losing up to 20 feet of elevation each year as hotter temperatures melt ice and warmer ocean temperatures erode the ice at their fronts, according to the study.
