'Cos if its about the same surely even if all the worlds ice did melt the change would be much smaller than predicted...

The worst global warming predictions I have heard call for a 20 foot sea level rise. Compared to hundred foot and more variations in sea levels over geologic time, this seems small to me. Still, at 20 feet, all of New Orleans and Venice, much of Holland, southern Florida and parts of New York City, to name a few places, would be flooded.

Just over 2% of the world's water is tied up in glaciers (floating ice).
Antarctic ice sheet (continental ice) makes up 80% of the world's ice. Nearly 2/3 of the fresh water. Covers almost 1.5 times the area of the U. S.
If all the ice melted, the Sea level would rise 60 to 70 meters ( ~197 to 230 feet).

Antarctica holds about 90% of the world's fresh water. Most of its ice is not floating. If all of it were to melt it would raise ocean levels about 70m or about 230 ft.
Ice melting is not the only cause of sea level rise. As you heat water it expands. That is also a significant cause of sea level rise due to global warming.
