brim, allowing the ice to melt, will the glass over flow(?) I know the answer is no, then how is it, we are told that if the polar ice caps melt (Antartica land mass is quite a small percentage of its area) we will find sea levels rising?

The flaw in your arguement is that you started off with the ice in the water. Fill the glass, and suspend the ice over the top - now what happens?
The Greenland and Antarctic ice sheets are both on land, not water. I'm not sure where you have picked up the view that "Antartica land mass is quite a small percentage of its area". That is completely wrong, and the ice is two miles thick.

No, the glass will not overflow because the ice cube is already displacing its volume in the water. That's why there would be no change in sea levels if the north polar icecap were to melt; it is already displacing the sea that it is floating in. The ice on Greenland and Antarctica, however, is supported by a land mass and if it melts, the sea levels will rise.

It relies upon upon the temperature of the water. Water is maximum dense at 4 C, so if the water you upload is hotter than that, it is going to really shrink because the ice cools it. If the water is already cooler than that, or on the same temperature (basically taken out of the refrigerator for example), then it is going to improve because the ice cools it and could overflow the glass. After the ice has melted and the water has heated decrease back as a lot as 4 C back, the water element will be slightly below the top of the glass, when you consider that that it at the same time as that's maximum dense. Then at the same time as it heats up further it is going to initiate to improve and the point will upward push, yet probable not adequate to overflow a 2d time.

The water will not overflow because the ice cubes are already displacing the water as they are below the surface. However, if you got a giant stick of ice and put it in the glass like a straw, so that alot of the ice was above the water level, the glass would indeed overflow as the ice stick melted.
This is comparable to what you are talking about as alot of the ice is above sea level.

if the north pole melts there will be no rise in water level because the ice is already in the the water, the problem is is if the south pole melts. beacuse antartica is a land mass and the ice is on top of it. if that water get in the the system the water level will rise a lot.

A more proper analogy to answer your question would be - fill your glass with water till it is nearly full - then dump several large chunks of ice cubes in it. The water overflows because of the displacement value.
Polar Icecaps melting is EXTRA water volume, not already remeasured - nor will it regulate how it melts in the face of global warming. Its not just Antarctica Ice caps that pose a threat ya know. Do some research.

Surely if 2/3 of the ice "cubes" are underwater they will already contribute to the sea levels (however I wonder if their decreased density and therefore increased volume affects anything...?). The 1/3 ice above sea level surely does not contribute to it so regardless of whether the icebergs/sheet is on land, if a portion of the ice is above sea level when it melts it will increase the sea levl will it not?

A lot of the ice isn't in the water before it melts (is above the water as with icebergs or is on land).
