Below is some "news" about the Greenland ice sheet:
The Greenland ice sheet is poised for another record melt this year, and is approaching a "tipping point" into a new and more dangerous melt regime in which the summer melt area covers the entire land mass, according to new findings from polar researchers.
The ice sheet is the focus of scientific research because its fate has huge implications for global sea levels, which are already rising as ice sheets melt and the ocean warms, exposing coastal locations to greater damage from storm surge-related flooding.

Greenland's ice has been melting faster than many scientists expected just a decade ago, spurred by warming sea and land temperatures, changing weather patterns, and other factors. Until now, though, most of the focus has been on ice sheet dynamics — how quickly Greenland's glaciers are flowing into the sea. But the new research raises a different basis for concern.
The new findings show that the reflectivity of the Greenland ice sheet, particularly the high-elevation areas where snow typically accumulates year-round, have reached a record low since records began in 2000. This indicates that the ice sheet is absorbing more energy than normal, potentially leading to another record melt year — just two years after the 2010 record melt season.
“In this condition, the ice sheet will continue to absorb more solar energy in a self-reinforcing feedback loop that amplifies the effect of warming,” wrote Ohio State polar researcher Jason Box on the meltfactor.org blog. Greenland is the world's largest island, and it holds 680,000 cubic miles of ice. If all of this ice were to melt — which, luckily won't happen anytime soon — the oceans would rise by more than 20 feet.
Just one teeny problem; The 2012 figure (black line) in the graph above looks like it's heading off in a different direction from all the other years (see the bottom of the graph). But the guys the author took that graph from show something quite different:
The black line is not dropping relentlessly at all. It's moving off in the same direction as the other years. Nothing to see here. Move along! Is there such a thing as an honest Greenie?
Also note that the misquoted article says: "accurate records began in March, 2000", and Warmists are usually emphatic to say that a 10-15 year period is too short to allow any generalizations about climate trends!
