Water expands as it freezes. That's why your pipes can burst in your home during a hard freeze.

Conversely, water contracts when it warms up and liquifies.

Now, the enviro-NAZI's want us to believe that global warming will cause the polar ice caps to melt and RAISE the level of our oceans.

But is that actually possible? Most of the ice on our two poles resides above water, not land. The only water that will add to the volume of our oceans (even if global warming were true) would have to be that from ice above ground (a miniscule amount). Even if a large portion of all polar ice was above ground instead of water, the volume that said ice melting would contribute to our oceans would be greatly offset by the contracting volume REMOVED from our oceans by the melting of ice that is above water, and that's in a scenario in which ALL ice on this planet melts away.

Ice contracts when it melts. How likely is that fact going to contribute to RAISING our sea levels?!

Try this experiment: Add fresh water ice to a pitcher of salt water and mark the water level. Wait until the ice melts and then mark the water level. I won't spoil the suspense or prejudice your experiment by giving the results.

Exactly. Only the significant melting of many large glaciers over land would cause any measurable rise is sea level. The antartic glaciers would be key in this. Ooops! They're expanding, as noted in this article - some of the ice pack may be breaking off, but that's because the glaciers over the Antartic land mass are expanding, pushing more ice out over the ocean, which then breaks off.

How right you are, the sea level will actually fall as the ice melts.However,due to the mass of water this drop would hardly be noticed.

The "Melons" (green on the outside,red on the inside) love these natural events and use them in their propaganda.

Archimedes principal requires that the volume of fresh water displaced by ice exactly equal the volume of the melted ice, so by that standard, you are correct. The ice resting on the earth's hard surface, even below sea level, distorts the earth's elastic shell, which floats on a sea of liquid rock (magma). As this ice moves into the sea, as ice or water, the land underneath will spring up, slightly and land else where will sink very slightly, the entire configuration seeking the lowest total potential energy.

Floating icepack near the shores forms a stopper which prevents the ice on the antartic continent and northern land masses from flowing into the oceans and buoys up the other continents.

That's how losing the antartic ice cap could "raise water levels".

That notwithstanding, globaling warming and ice shelf scares in the popular press are, IMHO, hogwash.
