What about that melting ice?

As I remember from geology. There has been several ice ages. After the last one melted back the great lakes were formed. As the ice retreated towards the North pole area the land which was once covered lost a lot of weight. As I remember the land raised up to balance out from the loss of 1 mile of ice on it. Just wonder what's going to happen when the ice melts at Greenland, will the whole land mass lift up, will other areas sink? It's all floating on the earths mantel and that's all in balance. Just a thought, if Greenland goes up then some other areas will go down. Of course there must be some earthquake associated with that too. The crust which behaves like a plastic still will get cracks. Just wonder what areas that will effect.
