Default Will sea levels really rise if the glaciers melt?

I posting this here because there a good analytical minds here.

An experiment: Fill a tall clear glass half-way with ice cubes. Then
add enough water so the bottom cubes no longer touch the bottom
(i.e., they are all floating). Now put a mark at the water level and
wait until the cubes all melt. Did the water rise above your mark?

In my case, it didn't.


Here is an alternate, and probably more appropriate, test that you could
try.

Start with a rectangular fish tank. Place dirt and rocks in it such that
the dirt and rocks are high up on one end and have the dirt and rocks slope
down toward the other end to where they are at zero height on the other end.

Then, fill it half way with water and place ice in the water and also on the
dirt/rock "hillside" that is above the water line. That would more
accurately replicate the way that glaciers are on earth -- meaning that the
glaciers are both on top of the ground/dirt/rocks and also partially in the
ocean where the ocean meets the ground/dirt/rocks.

Wait until the ice in the fish tank melts. Let us know if the water level
rises in the fish tank as the ice melts.

Wanna take a guess as to what will happen to the water level?


Yeah, The water level will drop.

There will be two reasons:

1. Some of the water will be absorbed by the ground/dirt/rocks.

2. Some of the remaining water will evaporate because Al Gore says it
will eventually get so friggin hot because of global warming that the
water will cause that to happen. Not to mention that California
congress woman, Barbara Lee, says that same global warming will force
women to become prostitutes.
