Global+Warming+Assignment

** Global Warming Assignment (20 points) ** We looked into global warming as an issue earlier in the year (chapter 36). Now that we have studied photosynthesis and cell respiration we can see the carbon cycle in the biosphere as a natural give and take between producers and consumers. The greenhouse effect is the way the Earth’s atmosphere traps heat. This effect has given organisms the climates to which they have adapted. We recognize that some organisms are adapted to live in the desert, others in the tundra, //et cetera//. Recall that climate is loosely defined in our class as the average annual temperature and precipitation (rain, snow) in an area. Through this exercise you will read background on global warming and climate change. You will be challenged to think about the impact this may have on humans and other organisms. Last you will be given the chance to consider solutions and their pros and cons.

Use the links provided to find the article you need to read so you may answer the questions correctly. The bold headings are covered by one page but separate links are provided for the articles that address the questions.

Questions #1 – 8 are worth 1 point each. Answer on a separate sheet of paper. Science [] 1. What is the greenhouse effect? 2. What was the contribution to climate science made by Svante Arrhenius? 3. What are two ways the Earth can cause changes in global temperatures?

Causes [] 4. What are the top three greenhouse gases? 5. What are the sources for these gases mentioned in the article?

Effects [] Consider the effects of global warming listed as “already happening,” and the ones listed as “could happen later this century.” 6. Are any of these similar? Predict what might the impact of these effects be on: 7 a) food production? 7 b) public health? 7 c) our economy?

Solutions [] 8. What are three ways mentioned in the first link that will reduce greenhouse gases? ** The three parts to question 9 are worth 10 points! ** 9. Select either carbon sequestration or the stabilization wedges strategy to reduce greenhouse gases. Use either link below, or your own, to discuss the positive and negative parts; the pros and cons.

Your answer must state the following: 9a) At least two positives and two negatives to the strategy (name it, too), 9b) Do you think the strategy will work? 9c) Why do you think it will, or will not work?
