If the Polar Ice Caps Melt what would happen?
The melting of the north polar cap would not appreciably increase the volume of water in the oceans, since the north polar cap is resting on the water and not on the land. It would decrease the salinity of the oceans, however, and this would cause some serious problems. The melting of the south polar cap, which rests on the continent of antarctica, would add a great deal of water to the oceans and help to raise sea level, as well as contributing to lower salinity. The melting of the glaciers of Greenland would also significantly raise sea level.
