The Greenland ice cap IS melting, but that's just the tip of the iceberg

Politics - World - s.f. bayarea forums - craigslist: "The Greenland ice cap IS melting
This has been well documented for years, e.g.,
'Greenland's ice sheet could disappear within the next 1,000 years if global warming continues at its present rate, a report in Nature magazine suggests.
Jonathan Gregory and colleagues from the University of Reading, UK, say their studies forecast an 8C increase in Greenland's temperature by 2350.

They believe that if the ice cap melts, global average sea level will rise by about 7m (23ft).
Even if global warming was halted the rise could be irreversible, they say. '

The really, REALLY bad news:

It's rapidly creating moulins through the ice which will accelerate the process by a couple of orders of magnitude. (By comparison, the Larsen B ice shelf, all 7000' feet thick and 20 miles across, melted suddenly and unexpectedly in the summer of 2002 in just 35 days flat.)

'Ice is melting in Greenland faster than we
ever thought possible, fast enough that it?s alarming,?
Box believes. ?What controls the speed of a
glacier?s advance toward the sea is what?s going on
down at its bed. Adding liquid water to the bases
of glaciers via meltwater lakes that flow into moulins
is making these glaciers race along.
?What we have in Greenland is nothing short
of galloping glaciers.'

When (not if) Greenland finally goes, sea level will rise over 20' REAL FAST.
