Indeed, nothing.
Achimedes' law says that the mass of the ice cube is equal to the volume of the part of the ice cube that is below the water surface, multiplied by the density of the water. So when ice melts, the melting water will occupy exactly the same volume as the "hole" in the water that the ice cube leaves.
Two minor modifications:
- Archimedes' law is based on the assumption that the density of air is zero. If you are an astronaut you may like to repeat the experiment on some planet with a very high air pressure, such as Venus, and see that the water level will actually fall a little. Otherwise, try this experiment: Make the glass half full, put an ice cube into it, and fill the glass with oil. You may notice that the water/oil line falls a little as the ice melts, because the "atmosphere" (now consisting of oil) has a non-neglible density.
- The melting ice may lower the temperature of the water, and thereby causing the water to contract (or expand if it's near the freezing point already).

Nothing so long as the water is above 4 C,
below this temperature the water will expand so the ice cube will cause the glass to overflow as it lowers the temperature of the water. The level of the water in the glass will drop as it contracts when approaching room temperature.

Ice takes up more space than liquid, so the water will be lower in the glass.
So, if all the ice melts at the north pole, will the ocean level drop?

Some of each ice cube is above water level, so when the ice melts, a tiny amount should overflow from the glass. But the property of surface tension may prevent this happening. Depends on how accurately you fill the glass.

Frozen water occupies more space than liquid water due to its crystal molecule arrangement. If you did that, then the water level would be a tiny little bit lower when the ice melts.
Tysavage2001: the droplets are from condensation of humidity in the air. The glass doesn't "sweat" liquid from within.

nothing would happen. Actually the water will be less when it melts as the ice takes up more space than the actual water in liquid form.

particular, that's a great thought. Rabbits tolerate chilly climate rather plenty yet can quite get warmth stroke and die. you additionally can fill empty water or soda bottles and freeze them and lay them interior the cage for the rabbit to lie next to to relax off. and since the different poster stated, misting the rabbit's ears with cool water will help cool the bunny off in very heat climate.

Nothing, it stays the same except the ice melted

The level will drop since water expands when it freezes, so when it melts it will contract.

it will be lower as water is larger as a solid than a liquid
