As for how long it takes for it to melt, here's
an article to
ponder from Science Daily, "Ancient Glacial Melting Shows That Small Amount
of Subsurface Warming Can Trigger Rapid Collapse of Ice Shelves". And here's
a video from 2005, from the NY Times Science reporter Andrew Revkin that
ties into the article regarding speed of melting. "You can see it happening,"
one scientist tells Revkin. And
here's a video from a day or so ago, showing
ice from a glacier falling off Greenland and causing a huge wave. [ Reply to This | Parent | # ]

Not that one should minimize this, but do note that it was only the surface of
the ice that was melting.
OTOH, lakes that suddenly disappear down a hole in the ice to who knows where
are quite worrying. Water is much better at distributing heat flow than ice,
and it also lubricates the flow of ice over rock.
I think the wrong pieces of that article are being emphasized. (I'm *assuming*
it's the same one I read earlier.) Much of the ice that flows off of Greenland
is still ice when it hits the water. It doesn't need to melt until later.
What's been worrying glaciologists in the articles that I've read is water
flowing around at the base of the glaciers.[ Reply to This | Parent | # ]

Actually, I'm in favor of Global Warming. Without it, I don't see how we can
feed the population of the world in one to two hundred years. Death by
starvation will be a much greater factor than today. Global Warming will be
necessary to the survival of great numbers of the great great great
grandchildren of today's population.[ Reply to This | Parent | # ]
