Final comprehensive take-home exam – worth 200 points
Research paper – ~15 page paper worth 100 points
Research Paper:
This course requires an in-depth library/web-based research paper on some aspect of global climate change. Some examples might include an update of the “cool-tropics paradox”, the causes and consequences of the late Paleocene thermal maximum, or the role of the Southern Ocean in regulating glacial-interglacial variations in atmospheric carbon dioxide levels. Alternatively, the paper may instead be focused on current climate trends such as the role of sulfate aerosols on greenhouse warming or of how CFC concentrations in the atmosphere are influencing stratospheric ozone levels. I expect the papers to be approximately 15 pages in length (single spaced), well written and fully referenced. Diagrams, figures and tables are encouraged. The topic of the paper is due on February 5, 2004. I expect a brief 1-paragraph summary of the topic that you expect to research. The 1-paragraph summary is worth 10 of the 100 points.
If the paper is not turned in on February 5, you will
lose 10 points. I will exercise the option to approve or not approve/modify
the topic.
