NASA: Greenland Glacier Melting Rapidly

A giant glacier in Greenland is rapidly melting, according to NASA.

A recent study in the journal Science notes that the glacier, Zachariae Isstrom, initially came loose in 2012—ending a period of glacial stability and ushering in years of rising waters.

It drains an area roughly the size of five percent of Greenland's entire ice sheet.

If the glacier melted completely, it would raise ocean levels over 18 inches all on its own.

And now, according to NASA, it's "on a crash diet" and is "losing 5 billion tons of mass every year"—all into the northern part of the Atlantic Ocean.

Jeremie Mouginot, one of study's authors, said, "The shape and dynamics of Zachariae Isstrom have changed dramatically over the last few years. The glacier is now breaking up and calving high volumes of icebergs into the ocean, which will result in rising sea levels for decades to come."
