‘Heat Dome’ Linked to Greenland’s Biggest Melt in 30 Years

Last week there were the pictures of an iceberg twice the size of Manhattan breaking off Greenland’s Petermann Glacier.

Now there are NASA images showing that in four days earlier this month, Greenland’s surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations.

The space agency adds that nearly the entire ice cover of Greenland, from its thin, low-lying coastal edges to its two-mile-thick center, experienced some degree of melting at its surface, according to measurements from three independent satellites analyzed by NASA and university scientists. The changes happened from July 8 to July 12.

NASA says "this extreme melt event coincided with an unusually strong ridge of warm air, or a heat dome, over Greenland. The ridge was one of a series that has dominated Greenland’s weather since the end of May.
