The Greenland ice sheet plays a crucial role globally weather , locally, impacting the surface energy budget , climate , contributing to current future sea level rise. Figure 1 shows the cumulative number of days that the Greenland Ice Sheet experienced greenland surface greenland melting during ( right image) for, along with comparison images for the record year for melt days. The Greenland ice sheet ( Danish: Grønlands indlandsis Greenlandic: Sermersuaq) is a vast body of ice covering 1, 000 square kilometres greenland ( 660, 710, 000 sq mi) roughly 80% of the surface of Greenland. In addition we assessed mass changes from 78 monthly volume Gravity Recovery Climate Experiment ( GRACE) solutions. If that mass of frozen freshwater should melt altogether it would raise global sea level by approximately 7 meters. For a few volume days in July of, it was so hot in the Arctic that nearly the entire surface of the Greenland ice sheet turned to slush. The total ice volume change of the entire ice sheet amounts to − 205. Greenland Ice Sheet Danish Indlandsis, glacier covering about 80 percent of the island of Greenland , also greenland called Inland Ice, greenland single ice cap , the largest ice mass in the Northern Hemisphere second only in size to the Antarctic ice mass.

Ice melt across Greenland is accelerating , the volume of meltwater running into the ocean has reached greenland levels that are probably unprecedented in seven eight millennia. However the general evolution of the GrIS volume remains similar in the scenario starting with an ice- free Greenland in that starting from a full ice sheet. The ice sheet is.

The Greenland ice sheet is a major contributor to global sea level rise and plays a crucial role in the surface energy budget, climate and weather of the Arctic. Estimates of the spatial extent of melt across the Greenland ice sheet ( GrIS) are obtained from brightness temperatures measured by the Special Sensor Microwave Imager/ Sounder ( SSMIS. 2) Calculate the volume of each ice sheet, by multiplying the ice- sheet areas by their average thicknesses, all provided in Table 2, obtaining ice sheet volumes of 2, 604, 142 cubic kilometers and 29, 315, 965 cubic kilometers for Greenland and Antarctica, respectively. Ice Sheets Data from NASA' s GRACE satellites show that the land ice sheets in both Antarctica ( upper chart) and Greenland ( lower) have been losing mass since. Both ice sheets have seen an acceleration of ice mass loss since. Ice volume calculated anew Date: February 12, Source: ETH Zurich Summary: Researchers have provided a new estimate for the glacier ice volume all around the world, excluding the Greenland and.

Although Greenland is extremely remote, a vast island lying at the northern end of the Atlantic Ocean, the sheer volume of ice covering it means its fate could have global repercussions. A new NASA study says that an increase in Antarctic snow accumulation that began 10, 000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers. The Greenland Ice Sheet is a vast body of ice covering roughly 80% of the surface of Greenland.
