Global Carbon Dioxide Increase

Student Directions

Faculty will need to develop their own Directions as a modification of the ones on "Carbon Dioxide Assignment" at


Give/show students the Keeling Curve. As a minute paper, homework etc. ask the following (part or all).

  • This is the familiar Keeling Curve showing carbon dioxide data collected in Hawaii from 1958-2006. If the data had been collected in the southern hemisphere of the earth as opposed to the northern hemisphere, how would be figure look different? Why?


  • Draw a concept map of the metabolic processes? that combined together result in the changes we can see in the Keeling Curve. Include the following scales: atomic/molecular (e.g. CO2), individual organism (e.g. a tree), ecosystem (e.g. forests), and global (northern or southern hemisphere).
