What the prior poster is referring to is not a melting event, but an ice
slippage. The arctic icecap is pretty much all already floating so it's melting
won't raise sea level. The situation is different in antarctica. Much of the
antarctic ice mass is not floating, but instead is supported by rock that is
below sea level. Some of this non-floating ice is thousands of feet above sea
level. It is possible, though not certain, that a relatively small rise in sea
level could reduce the frictional forces that hold this ice in place just enough
that large chunks of it could slide into the sea and begin floating. A rapid
change from non-floating to floating of a large ice mass would a) cause a
monstrous tidal wave and b) raise global sea level very rapidly indeed. Whether
the rise would be imperceptible or than a foot would depend on the volume of ice
that switched from being above sea level to below sea level.

You should read the two new reports, look at the
charts, and then comment. Otherwise, you are
not expressing anything of value. Thanks.[ Reply to This | Parent | # ]

A rise of one foot in an ocean that is not in motion is one thing, but in an
ocean that is in constant motion, it becomes almost meaningless.
A rise of even a couple inches, although it may not cover as large an area,
could have huge effects on tides and surf patterns, particularly the farther you
get from the equator.[ Reply to This | Parent | # ]
