You are correct with respect to floating ice that melts. Actually, ice floats in water with 89 percent of the ice being below the water surface, and 11 percent being above the water level. This is true with floating icebergs in the ocean. But, not all ice in nature is floating. A lot of glaciers are actually located on the ground and are not floating in water. So, when they melt, the water level will rise significantly.
