Ice Melted In Green Land:
Greenland is a massive island and autonomous Danish territory between the North Atlantic and Arctic oceans. Much of its land surface is covered in ice. But heatwave over Iceland is melting the Ice sheet over Green land and it is raising the sea level over 0.5 mm. According to the Danish Meteorological Institute 10 Billion Tonnes Of Ice Melted in Green Land.
An extraordinary melt event that began earlier this week continues on Thursday on the Greenland ice sheet, and there are signs that about 60% of the expansive ice cover has seen detectable surface melting, including at higher elevations that only rarely see temperatures climb above freezing.

July 31 was the biggest melt day since at least 2012, with about 60% of the ice sheet seeing at least 1 millimetre of melt at the surface, and more than 10 billion tons of ice lost to the ocean from surface melt, according to data from the Polar Portal, a website run by Danish polar research institutions, and the National Snow and Ice Data Center. Thursday could be another significant melt day before temperatures drop to more seasonable levels.
According to Ruth Mottram, a climate researcher with the Danish Meteorological Institute, the ice sheet sent 197 billion tons of water pouring into the Atlantic Ocean during July.
This is enough to raise sea levels by 0.1 millimetres, or 0.02 inches, in a one-month time frame, said Martin Stendel, a researcher with the institute.
