THE GREENING OF GREENLAND

Did you catch the story in yesterday's media about the unprecedented ice melt occurring in Greenland this summer?

Just last week, a giant  iceberg twice the size of Manhattan Island  broken away from the end of Greenland's Petermann glacier. Now we are learning that a  heat-dome that moved over Greenland on July 8 caused surface melt to soar from 40% to an unprecedented 97% in just four days.

In a typical summer less than half of Greenland's surface ice melts.

Apparently, this kind of melting does occur once every 150 years on average, scientists have just never witnessed it before.

Greenland is changing very fast as its ice sheet as a whole is shrinking, melting, and reducing in size as the result of globally changing air and ocean temperatures.

Glaciologists are not panicking, but they are worried about Greenland's worrying potential to stoke sea levels in the coming decade.
