Think about it.
Yep, Archimedes noticed something like that! OK, another science lesson. When you dump ice into water (or any liquid) it will displace water (think of it as making room). Once the ice already in the water melts, there is NO change in level.

The melting of ice in the Arctic has no effect on rising ocean levels. Ice melting that is located on continents do. Melting Greenland ice raises ocean levels as does Antarctica (an actual land continent).
