>>22291849Melting an ice cube in a glass of water would not change the water level. Ice is less dense than water and so occupies a larger volume (which is why glass bottles burst if you freeze them).
However, you can't apply that to the ice caps. A lot of the ice on Earth doesn't
float.It melts, and breaks off or slides down a land mass or whatever, after which it melts. That's extra water.
