The Antarctic ice sheet contains an estimated 7.0 million cubic miles of ice. If the entire ice sheet melted, how many feet would the average global sea level rise? The density of ice is about 0.90 g/cm^3. The density of water is about 1.0 g/cm^3. The total area of the world's oceans is about 134 million square miles.

  1. Well, If one considers the ice to be floating, then like magic when it melts, the water level does not rise. Think on that.

    Fill a glass with ice to the above the brim. Add water to the absolute rim of the glass. Now let the ice melt and see if the melted water overflows. (It doesn't).

    Why is this? Think about archemedes principle and the density of ice.

    Now your question: this melting ice sheet is an urban myth. The increase of sea levels will not result from floating ice, but rather from land ice /snow, or ice that is resting on the bottom of the Arctic ocean (which there is little of that, mostly around Canada shore). look at the words and pictures here; http://express.howstuffworks.com/ask-mb-ice-melt.htm

    they show a picture of floating ice! Your exeriment with the ice water will debunk that.

    However, they are right about greenland, and glaciers melting, and land ice, and ice resting on the bottom of the Arctic Ocean.

    Many folks in this world live by the idea that if you say something enough, people will believe it, and cite it as references in a paper.

    Few actually do the experiment.
