Second giant ice island set to break off Greenland glacier http://apocadocs.com/s.pl?1314904862
New photographs taken of a vast glacier in northern Greenland have revealed the astonishing rate of its breakup, with one scientist saying he was rendered "speechless."
In August 2010, part of the Petermann Glacier about four times the size of Manhattan island broke off , prompting a hearing in Congress.
Researcher Alun Hubbard, of the Centre for Glaciology at Aberystwyth University, U.K., told msnbc.com by phone that another section, about twice the size of Manhattan, appeared close to breaking off....
In 2009, scientists installed GPS masts on the glacier to track its movement. But when they returned in July this year, they found the ice had been melting so quickly -- at an unexpected 16-and-a-half feet in two years -- that some of the masts stuck into the glacier were no longer in position....
"I'm very familiar with the glacier. It's very hard to sort of envisage something so big not being there ... to come back and basically see an ice shelf has disappeared, which is 20 kilometers across (about 12 miles) ... I was speechless and started laughing because I couldn't sort of believe it," Hubbard added, speaking to msnbc.com.

I thought Greenland was too big to fail.
