When sea ice melts, the sea levels go lower. (The reason why ice floats is that it is less dense than water, melt it and it becomes more dense and takes less space and levels go down. Try it in a glass with ice and water and leave the ice to melt.)
I'll challenge you on that one. I think when floating ice melts the water levels do not change. The volume of the ice does reduce as it turns to water , but that is exactly compensated for by the ice originally above the waterline melting into the water.

Land based ice melting will obviously increase water levels.
