Wed July 25, 2012 '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."
Wired writes that "while no one event can be blamed on climate
change, the mel
