Why the Greenland and Antarctic Ice Sheets are Not Collapsing

Why the Greenland and Antarctic Ice Sheets are Not Collapsing
Global warming alarmists have suggested that the ice sheets of
Greenland and Antarctica may collapse, causing disastrous sea
level rise. This idea is based on the concept of an ice sheet sliding
down an inclined plane on a base lubricated by meltwater, which
is itself increasing because of global warming.
In reality the Greenland and Antarctic ice sheets occupy deep
basins, and cannot slide down a plane. Furthermore glacial flow
depends on stress (including the important yield stress) as well
as temperature, and much of the ice sheets are well below
melting point.
The accumulation of kilometres of undisturbed ice in cores in
Greenland and Antarctica (the same ones that are sometimes used
to fuel ideas of global warming) show hundreds of thousands of
years of accumulation with no melting or flow. Except around the
edges, ice sheets flow at the base, and depend on geothermal heat,
not the climate at the surface. It is impossible for the Greenland
and Antarctic ice sheets to 'collapse'.

you're not seeing the full picture.

RE: Why the Greenland and Antarctic Ice Sheets are Not Collapsing
Is the sea level rising? Does Greenland have more ice than when the Vikings lived there and called it Greenland? Did all the polar bears die during that period or did they hibernate floating on their backs?
But I digress, it is you who are not seeing the full paper, clicking the link I posted above causes the pdf file to be downloaded.

RE: Why the Greenland and Antarctic Ice Sheets are Not Collapsing
I am reading the paper.
"relative infancy":
http://concen.org/forum/showthread.php?tid=32290&pid=186555#pid186555
my point is, as maybe illustrated here in this quote from the paper linked in the original post:
Quote:Greenland differs from Antarctica in that the ice sheet spills out
through gaps in the mountain rim, and the glaciers overlie deep
narrow valleys. According to van der Veen and others such valleys
have higher than usual geothermal gradients, so it might be
geothermal heat, rather than global warming, that causes some
Greenland glaciers to have higher than usual flow rates.
emphasis added.

There is no discussion in this paper about ongoing research into geo-basal pressure from The Greenland Ice Sheet in conjunction with geothermal heat together precipitating increased volcanic activity. It's scope is relegated to the subject of global warming.

Also, of note, is the relatively "low" degree of Glacial 'disturbance' needed to affect the Earth's rotational equilibrium were it to hypothetically be trouble in Greenland as oppose to Antarctica, as the ice mass is set off from the true magnetic pole in the former case. QED?
