Climate Change Scenario
MTH/215 Version 2

Climate Change Scenario
Most of the world’s ice that can melt into the oceans occurs in two regions: Antarctica and Greenland.
Your goal is to determine the effects of global ice melting on the earth’s oceans, (i.e., what if all that ice
melted).
There are three main roles in this project. Select a role and complete the task listed under the role.
Role #1 Satellite Photo Analyst 1
Use the satellite photo of Antarctica from NASA, scale, and your own research to answer the following
questions. You may want to research geometric formulas for area and volume to help you in your
calculations.
a) Research the average thickness of the ice in Antarctica in kilometers. 2.45
b) Using any geometric formula you feel is appropriate and the photo below, find the
estimated area of Antarctica. What is the volume of ice in Antarctica? 11,965,700
c) If the volume of water is approximately ⅚ of the original volume of ice, what volume of water
would be added to the oceans if all the ice in Antarctica melted? Give your answer in cubic
kilometers, cubic meters, and gallons.
d) If the volume of the oceans combined is about 1,350,000,000 cubic km, by what percent would
the volume of the oceans increase if all of the ice in Antarctica melted? 13.55 %
e) Include your sources, calculations and results.

Role #2 Satellite Photo Analyst 2
Use the satellite photo of Greenland from NASA, scale, and your own research to answer the following.
You may want to research geometric formulas for area and volume to help you in your calculations.
a) Research the average thickness of the ice in Greenland in kilometers.
b) Using any geometric formula you feel is appropriate and the photo below, find the estimated
area of Greenland. What is the volume of ice in Greenland?
c) If the radius of the earth is about 6400 kilometers and the oceans cover about 71 percent of
the Earth’s surface, what is the surface area of just the oceans on earth? Give your answer
in square kilometers..
d) If the volume of the oceans combined is about 1,350,000,000 cubic km, by what height with
the oceans increase if all of the ice in Greenland melted? Give your answer in kilometers,
meters, and feet.
e) Include your sources, calculations and results.

Role #3 Oceanographer
Research how fast the ocean levels are rising in meters per year and the average depth of the oceans in
meters. Then answer the following questions:
a) How fast would that rate be in feet per decade?
b) How long would it take for the ocean levels to rise by 20 feet?
c) What is the growth rate of the ocean heights per year (in %)?
d) If we are able to reduce the rate of ocean levels rising by 40%, how long would it take for the
ocean levels to rise by 20 feet?
