Sea Levels Rising Fast on U.S. East Coast - NationalGeographic

7. OK, several misconceptions here.

First, the density of liquid water changes very little with temperature, from 999g/cm^3 to 995g/cm^3 , so I dont think that is a large effect.
Secondly, melting icebergs will not raise the water level at all. Archimedes, a few thousand years ago, proved a floating body displaces a weight of water equal to its own weight. Thus, when the ice melts into water, its weight does not change, and the water level does not rise.
Glaciers are above sea level, their melting will cause a significant sea level rise.
