  1. I raised the issue of the melting ice about two years ago and my comments were summarily ignored. In simple terms the vast majority of a lump of ice floating in water is actually displacing water (by being underwater). When it melts, the volume and displacement is less, so (even taking the tip of the iceberg into consideration) if anything, the water level would go down.

  2.  British Brexit Confusion  If you have water in a pipe and the water freezes, it (potentially) bursts the pipe because it expands. It's therefore only rational that when it returns to a liquid state, it shrinks. This is an extract from Wikipedia on ice. "When water freezes, it increases in volume (about 9% for fresh water).[11] The effect of expansion during freezing can be dramatic, and ice expansion is a basic cause of freeze-thaw weathering of rock in nature and damage to building foundations and roadways from frost heaving. It is also a common cause of the flooding of houses when water pipes burst due to the pressure of expanding water when it freezes".

  3.  British Brexit Confusion  The weight in itself isn't the issue. As I recall, there's about 9% loss of volume when water goes from ice to liquid, so it makes sense that when you consider about 90% of an iceberg is underwater, there would be about 8% less displacement when the iceberg melts.
