l to show wha- Question #8 (10 points) Dr. Fudgefactor of the Heartland Institute argues that the melting of glaciers in the Arctic Ocean will have no effect on sea level rise, it's a natural process and besides sea ice is on the water, so no big deal he adds, "does melting ice in your cocktail make your glass fuller?" Do you agree with him, that there will be no eustatic sea level rise if all the Arctic ice melts? Please explain the reasons for your answer - Yes or no is not sufficient. The "de-icing" of the Arctic is having a positive feedback on Arctic warming. Why is this?Explanation / Answer
We know that the density of ice is less as compared to the density of water and hence we can say that water occupy less volume than ice, therefore if the water melts and remains in the system only and the system is isolated the there won't be any increase in the volume of ice + water. Even the combined volume of water and ice would be less if all the ice melts as the volume occupied by the melted water would be less as compared to the ice which cause this added water. A real life example of this can be seen when a bottle completely filled with water is kept freezer and it burst when it freezes as the volume of ice in more.
If we talk about the Arctic case then we can say that de-icing is having a psoitive feedback as the melting of the arctic ice will require heat and thus this process takes a large amount of global heat so that the continents are not heated to the extreme extent.
