But we don't live in a glass of iced water do we, and also hotter water also
takes up more room. Its not just the ice. I'm probably wasting my time
replying to this, but it is an interesting subject, nonetheless.
The current situation is that the ice is also stuck in a place and when it
melts is is free to flow to other places, and as although ice takes up more
room than water due to its crystalline form, the fact that much of it is not
actually in the sea has to be borne in mind here. A glassier is a frozen
river flowing to the sea after all, and if it thaws that water will get to
the sea faster.
Of course evaporation has a part to play in the opposite direction, but as
sea levels are rising, I think the trend has to be for this to continue to
places in the world where land is low lying.
End of waffle.

Essentially you are correct. Assuming nothing happens, like a nuclear
war, that makes a fundamental change in the population and the
atmosphere, the earth will get warmer. The science is certainly
looking that way right now. If we are going to blame CO2 levels, it
needs to be pointed out that when you track CO2 for the last 10,000
years, it tracks world population as closely as any other metric, That
can easily be explained by agriculture. They cut down forests and plow
up grasslands to grow crops. The plants they grow are harvested as
soon as they are mature so they are not much of a CO2 sink.
Any global warming plan that is not going to scrub a few billion off
the population is simply snake oil sold by hucksters like Al Gore who
wants to make billions from a carbon tax by selling worthless
"credits" for that money.
Different scenario. Some of the melting ice is sitting on land and will
be added to the sea in the form of water.
Repeat your experiment filling the glass with ice, add water to the rim.
Now set a couple more cubes on the rim of the glass. That is closer
to what may eventually happen.
Icebergs are not glaciers -- they are pieces of glaciers which fell off.
When they melt they will not raise the level of the ocean but when they
fell into the ocean in the first place they _did_ raise the level. If you
don't believe that, fill your hypothetical glass to the brim and then, very
gently, place an ice cube into it and see what happens.
Unless you've actually been there you would not believe the amount of ice
covering the land in Greenland. When it melts, whether in the form of
icebergs or not, you better believe that the level of the ocean will rise.
And Greenland has a fraction of the amount of ice that Antarctica does.
Now do this again, but substitute a good whiskey or other hard liquor
for the water. Now put a mark at the "whiskey" level and wait until the
cubes all melt. I'll bet that the level in that glass will have gone
down at least 75%, and you'll be seeing TWO glasses!
What this proves:
If we fill all the oceans with booze, we'll have nothing to fear!
(except possibly liver damage) :)
