There's a lot of argument about the speed with which the Antarctic and
Greenland ice sheets are going to slide off into the ocean. I'm not
planning any investments in waterfront property.

Neither are 'sliding' anywhere. The calfing of icebergs is NORMAL !

Sure, it's just that there is more of them these days.

The production of icebergs varies from year to year. The AGWists pick the years when
production's higher to make their invalid point.


Neither are likely to melt either. The average temp in Antarctica is -20C ! It's pure
catastrophism (and junk science) to suggest they're melting.

They don't have to melt - at least not in the Antarctic - to raise the
water level. The floating ice shelves around the Anarctic are already
breaking up,

The melting of floating ice doesn't increase sea level (other than minutely).


which means that ice is flowing off the Antarctic
mainland appreciably faster than it used to.

It *may* mean that. It also probably means that more ice is being formed in Antarctica.
Hence the extra weight of ice is causing it to flow faster. Increased ice formation in the
Antartic Ice Cap is to be expected as more humid air (from a warmer atmosphere) leads to
greater precipitation as snow and resultant formation of ice.


The arguments are mostly about what further global warming will do to
the rate that at which the ice slides across Greenland and Antarctica.
It doesn't have to melt in place to create a problem.

It slides only because of its weight. Increased sliding suggests more weight = MORE ice.
