GEOG 3390 D01 Assignment # 1 1 CLAYTON H. RIDDELL FACULTY OF EARTH, ENVIRONMENT, AND RESOURCES DEPARTMENT OF ENVIRONMENT AND GEOGRAPHY GEOG 3390 INTRODUCTION TO CLIMATE CHANGE AND ITS CAUSES ASSIGNMENT # 1: REVIEW OF CLIMATE SYSTEM INTRODUCTION Two important concepts with regards to climate change are the radiation laws that govern incoming and outgoing radiation from a body in space, as well as the concept of the greenhouse effect, as applied to outgoing radiation from Earth. The g reenhouse effect is vital to, not only the radiation budget, but also life on Earth. The purpose of this assignment is to: (i) apply the basic laws of physics to the radiation from planetary objects; (ii) understand the radiation budget of the Earth and Su n; and (iii) appreciate your personal emission of greenhouse gases and its effects on the greenhouse effect NOTE : the quality of your presentation (neatness, spelling, grammar, etc.) is an important component of your grade for this assignment. Make sure t o provide answers in complete answers. Failure to use complete sentences will result in a grade of 0 for that question. Provide all answers to the following questions in one document (do not submit handwritten paper assignment) ASSIGNMENT SECTION I: Application of Laws of Physics (10 marks) Mars is the fourth planet in our solar system. The surface temperature of Mars is -62 C. For t his assignment, assume that Mars is a blackbody and has the same properties of the Earth (i.e. size, atmosphere, etc.). Answer the following questions using the equations discussed in the lectures and textbook (make sure to include calculations for full marks): Question 1: What is the energy emitted per surface ar ea of Mars ? (2 marks) Question 2 : What is the wavelength of maximum energy emission of Mars ? (2 marks) Question 3 : What is the type of radiation calculated in question 2 ? (i.e. mic rowave , infrared, ultravi olet, etc.) (1 mark ) Question 4: How does the total emitted energy and wavelength of maximum energy emission of Mars compare to those for the Sun (6000K) and Earth (300K)? Why are these values different? (3 marks) Question 5: If the temperature of Mars is increasing, what d oes this tell us about Ein and Eout ? (2 mark s) GEOG 3390 D01 Assignment # 1 2 SECTION II: Energy Budget (10 marks) The Sun is a 6000 -K blackbody. Question 5: a. How much power per unit surface area (P/a) is the Sun radiating? (2 marks) b. If the surface area of the Sun is 6.07 x 10 18 m2, what is the total power emitted by the object ( in Watts) (2 marks) Question 6: Imagine that the Sun had a radius twice as large as it does at present, but the Sun emitted the same total amount of energy. What temperature would the Sun have to be? (2 mark s) Question 7: What happens to the Earth’s solar constant and surface temperatu re if the radius of the Sun doubles? (2 mark s) Question 8: Would the percentage of solar radiation that is reflected and absorbed by the Earth’s atmosphere change if the radius of the Sun doubles? Explain and justify your answer . (2 marks) SECTION III: Carbon Footprint (10 m arks) In this part of the assignment, I would like you to gain an appreciation for the amount of carbon dioxide produced by everyday activities. To do this , you are asked to calculate your carbon footprint. Go to following website to calculate your carbon footprint: https://www.carbonfootprint.com/calculator.aspx . Un der the Welcome t ab, make sure to enter your Country and Province . Once you have completed entering that data, work through the various tabs . If a tab does not apply, do not include the information. If you are not sure, you can estimate the values (e.g. if you have not flown since COVID -19, you can should use information prior to the pandemic). Y ou should be as accurate as possible as to the amount of dollars for each of the categories . Before moving onto the next tab, make sure to click on Calculate Household Footprint. Question 9: What is your total carbon footprint in metric tons of CO 2e? Also i nclude the metric tons for each of the categories listed (house, flights, car, motorbike, bus & rail, and secondary) . (2 marks) Question 1 0: Describe how your footprint compare s to the country average and world average? Has this comparison surprised you? Why or why not? Include the graphic that compares the three footprints. (4 marks) Question 1 1: Using the information provided on https://www.carbonfootprint.com/mi nimisecfp.html , describe three cost saving actions that you can use to reduce your carbon footprint . In your answer, explain how these can be applied in your situation. (4 marks)
