Rise in Sea Level If the global climate were to warm significantly, the Arctic ice cap would melt. It is estimated that this ice cap contains the equivalent of 680,000 cubic miles of water. Over 200 million people currently live on soil that is less than 3 feet above sea level. In the United States, several large cities have low average elevations, such as Boston (14 feet), New Orleans (4 feet), and San Diego (13 feet). (Sources: Department of the Interior, Geological Survey.)

(a) Devise a plan to determine how much sea level would rise if the Arctic cap melted. (Hint: The radius of Earth is 3960 miles and 71% of its surface is covered by oceans.)

(b) Use your plan to estimate this rise in sea level.

(c) Discuss the implications of your calculation.

(d) Estimate how much sea level would rise if the 6,300,000 cubic miles of water in the Antarctic ice cap melted.
