So you are saying that Greenland is a 2000+ metre-high iceberg.

It's only just occurred to me that this mountain of ice had to get
there somehow to have the effect it is having on the region from
Newfoundland to Norway and Siberia.

To lift all that water from the oceans and pile it two miles high on
top of the Greenland mountains required a lot of energy. since the
Arctic region was covered with snow and ice during the last ice age,
where did all that energy come from?

You have proof of this ice age or is it some vacuous spin drift to aid
the lamentable in search of the unprofitable?

None the less the fact remains to be seen how any ice got there
bearing in mind before such ice ages there was one presumes 6 months
daylight at a time as per usual r is there some proff of things going
otherwise?

The top link is a set of weather charts from November/December 2008.
But any set of weather charts will reveal the overall progress of Low
and High pressure cells across the USA.

Any that leave the east coast far enough up the coast to reach the
North Atlantic (that is: most of them) will become entangled in the
system that holds them to a nearly parallel course west to east at 60
degrees north.

When there is slack pressure in the system they may go further north
to the Davis Straight between Canada and Greenland. What stops them
doing so is that there is a high mountain of ice on top of Greenland
and it affects the weather.

Once it affects that part of the weather it affects it for the whole
world because it is out of the Davis Straight that not only most of
Arctic icebergs float but also almost all of the world's cold water
leaves the Arctic too.

There is a weir across the Arctic Ocean that runs from Russia to the
Mid Atlantic Ridge.

Once surface water (forced over to the western reaches of the Arctic's
surface by the weather*) cool enough, the water drops down (at 4
degrees centigrade it is heavier than freezing water and much heavier
than ice.) This relatively warm water fills the bottom of the sea as
far as that dike will allow.

Any further falling water pushes the heaviest stuff out of the ocean
altogether. It then makes its way down to the Weddel Sea in
Antarctica. From there is begins to feed all the fish in all the
world's food chain.

I don't know how tall the mountains are in Greenland but I do know
that they must be nearly as high as the top of the ice or the ice
couldn't form on it, could it? It would behave as all wind-drifted
masses behave and fall into the sea on the east coast of the country -
as a giant dune, top first.

Or wouldn't it?
