This Week: Carbon Cycle
This is the start of our first part of the lecture series on the Carbon Cycle. I have attached a powerpoint on the basics of this process. Please peruse them and work on the two deliverables for the week: Discussion and Work Paper #1.
Earth Research System Laboratory http://www.esrl.noaa.gov/research/themes/carbon/
Read through this primer on Carbon Cycle Science.
Greenpeace Documents on Carbon Cycle: A Counter-Perspective.
Read the transcripts of the House of Representatives Hearing on Carbon Cycle. Critique on three different issues discussed in the hearing. Provide some evidence to support your assertion or dissent to this question.
Please use peer-reviewed journals and follow APA-formatting. Main response: Monday at 11pm (150 to 200 word count). 2 reply posts to other peer comments with substantial comments (100 to 150 word count) due on Wednesday at 11pm. Participate here.
Rebalancing the carbon cycle [electronic resource] : Hearing before the Subcommittee on Energy and Resources of the Committee on Government Reform,
House of Representatives, One Hundred Ninth Congress, Second session, September
Carbon Cycle: Work Paper 1
Run the Carbon Cycle Simulation found in this link:
Answer the following questions:
1.If only one half of the flora in the world existed in 2100 (perhaps due to
deforestation), what do you predict the atmospheric carbon level would be ? How would you change the simulation to reflect this?
2. What is the relationship between increased carbon in the ocean and increased carbon in the soil? How else might carbon be transferred to soil?
3. Using the data generated by the simulation, determine the mathematical
relationship between the percentage increase in fossil fuel consumption and the increase in atmospheric carbon. Is the relationship linear?
1. What is the relationship between an increase in fossil fuel consumption
and increased carbon in terrestrial plants? How might this change flora
populations? What impact could twenty years at this level of consumption have on
2.What is the relationship between an increase in total carbon concentration (the smokestack) and increased carbon in the ocean surface? How might this change marine life populations? What impact could fifty years at this level of
emissions have on marine fauna? On marine flora?
3. In addition to circulating through the carbon cycle, where else might
excess carbon be found? In fifty years, where would you be most likely to see
4.Which areas are most highly (and quickly) affected by an increase in carbon emissions (and increase in fossil fuel consumption)? How would these effects manifest themselves? What are the dangers/benefits to these areas?
