View the graph found at: https://www.antarcticglaciers.org/glaciers-and-climate/ice-cores/ice-core-basics/, and the current CO2 concentrations found at: https://keelingcurve.ucsd.edu. Also, read the section on global warming in Chapter 11 of your textbook.
Compare current CO2 levels to the highest concentrations from the past 450,000 years. Based on data from these websites and 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 be 3-4 pages in length and conform to CSU-Global Guide to Writing and APA Requirements. Include at least 1-2 outside references. The CSU-Global Library is a good place to find these references. It is strongly recommended that you submit all assignments to the TurnItIn Originality Check prior to delivering them to your instructor for grading. If you are uncertain how to submit an assignment to TurnItIn, review the TurnItIn Originality Check - Student Guide for step-by-step instructions.
