Blink, it's gone: Greenland's surface ice melted 2 weeks ago
Posting in Energy  Staggering satellite photos from NASA reveal
that nearly all of the top layer vanished from July 8 through
12. Blame fossil fuels? One NASA boss advocates nuclear power to
stop global warming.  What a difference four days make.

Almost all of Greenland's surface ice melted in a 4-day period
earlier this month, NASA satellite photos reveal.  From July
8-12, 97 percent of the top ice melted. Normally, Greenland
loses about 50 percent of the layer over the course of a summer,
much of which quickly refreezes.  A NASA press release notes,
For several days this month, Greenland's surface ice cover
melted over a larger area than at any time in more than 30 years
of satellite observations. 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...On average in the summer,
