GEOG 170AAssignment 2: Climate Change ResearchPart I. Climate Change BasicsStep 1: Read the IPCC Summary for Policy Makers, especially sections SPM 3.2, 3.3, and 3.4,found on pages 17 26.Step 2: Answer the following questions.a. Explain in your own words what the term ppm of CO2-equivalent concentration(CO2-eq) means.b. What ppm CO2-eq concentration is believed necessary in 2100 to make it likely thatglobal average temperatures will not rise more than 2 degrees Celsius above 1850 1900global average temperatures?c. Emissions in 2050 of CO2-equivalent greenhouse gases will have to be reduced bywhat percent compared to observed 2010 emissions to keep CO2-eq concentration at orbelow this range?d. What percentage in 2100 of observed 2010 emissions of CO2-equivalent gases isallowable to keep CO2-eq concentration at or below this range?Part II. Climate and Energy ChallengesTo meet the target limit of 2 degrees Celsius of increase in global average temperature in 2100,significant changes in our energy system for agriculture, transportation, and electricity generationwill be needed. Also, further scientific research is needed (and currently underway) to betterunderstand feedback loops, and the potential climate system impacts of continued increases ingreenhouse gas concentrations in the atmosphere. Choose a topic for your own furtherexploration, from amongst Option A or Option B prompts.Step 1: Choose a research topic.Option A: Investigate and report on one potential change in our energy use that could contributeto meeting the target limit. Some examples: a renewable energy source, electric cars, expandingpublic transport, local or no-till agriculture, etc.Option B: Investigate and report on one area of current scientific research with regards topotential climate system impacts. Potential topics include: glacial ice sheet retreat and warmerair/ocean temperatures; oceans as a sink/source for carbon; pollution and clouds.Step 2: Write a short research paper, a summary and analysis of your findings on the topic youchose. Cite your sources appropriately, and include a separate Works Cited page of your citedreferences. Use APA style. Your paper should be 4-5 pages – double-spaced, Times New Romanfont, 12 point type. You will be graded on content, but writing is also evaluated. Your researchpaper will be reviewed for writing organization, style, grammar and you will be given detailedfeedback on it.
