Discussion:
View the global temperatures graph on this website: https://www.planetseed.com/sciencearticle/global-climate-change-and-energy, and the current carbon dioxide (CO2) concentration at: https://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
• Cite 1-2 outside sources
