The Settled Science in a Glass of Ginger Ale

While having a soft drink jammed with ice it came to me after some time elapsed and the solid had made its way to a liquid that the level of the drink was less. The displacement caused by the ice was greater than it was when it turned to water. Then it was I realized one of the first pieces of settled science I knew as a kid with a ginger ale and ice cubes bobbing wonderfully at the surface. This is the kind of science every kid knows before he has had common sense schooled out of him. I'm surprised that with all the angst about the levels of ocean rising no one has seemed to have recalled this! Why have not the popular scientists of the NY TIMES and HUFFINGTON POST and other such scientific organizations acknowledged this great catastrophic anomaly? Why shouldn't they wonder of such misbehaving physics? Shouldn't they see it just the other way---the water levels dangerously decreasing and the sands of coastline expanding? Why, I can just envision it! Even at high tide one might have to walk miles just to get one's toes wet. This explains at least partly, I think, why the Obamas weren't afraid to buy their 15 million dollar cottage on the globally warmed shores of Martha's Vineyard.
