View the global temperatures graph on this website: http://www.antarcticglaciers.org/glaciers-and-climate/ice-cores/ice-core-basics/, and the current carbon dioxide (CO2) concentration at: http://keelingcurve.ucsd.edu

Compare current CO2 levels to the highest concentrations from the past 450,000 years. Based on the information found on these websites and in the textbook, answer the following questions:

  • What is the current CO2 concentration in parts per million (ppm)?
  • Is this higher or lower than the highs over the past 450,000 years?
  • From which three sources do humans add CO2 to the atmosphere?
  • Which two sources take CO2 out of the atmosphere?
  • How does deforestation contribute to the global warming process?
  • Based on the data, are humans contributing to global warming, or is it strictly a natural part of the cycle? Defend your answer. You must weigh all of the data and use them to formulate your conclusion.

Your paper should meet the following requirements:

  • Be 3-4 pages in length (not including title & reference page)
  • Cite 2-3 outside sources in APA format
