Enough ice melted on Greenland this week to cover Florida in a half foot of water

It’s been a summer of record heat in the Northern Hemisphere, which scientists say would have been virtually impossible without the effects of human-caused climate change. Records have been shattered this year along the West Coast of North America, but the latest hot spot is in the far northeast corner of the continent, where Greenland is experiencing another major melt.

The Danish Meteorological Institute, along with the nation’s other Arctic research centers, report that “massive melting” is underway this week on the Greenland Ice Sheet, which covers much of the vast, frozen Danish territory.

“After a rather rainy summer so far, stable high pressure and warmer conditions (are) bringing high melt to the Greenland Ice Sheet this week,” explained Danish Meteorological Institute climate scientist Ruth Mottram on Twitter.

Mid-summer is prime time for melting on Greenland. While the current event is not as extreme as it was in 2019 in terms of the total gigatons of ice being converted to water, scientists say the total area seeing melting is larger this year and the volume “still would be enough to cover Florida with two inches (5 centimeters) of water.” A gigaton is 1 billion metric tons. 

Data from the Danish Meteorological Institute and Polarportal.org show that the Greenland ice sheet saw about 8 gigatons of melting on both Tuesday and Wednesday. In total, more than 26 gigatons have melted this week so far. That would easily be enough to put the Sunshine State under 6 inches of water.
