Carbon Dioxide Lab

Carbon Dioxide Lab
This week’s readings included a discussion surrounding the ongoing debate of whether or not to add carbon dioxide to the list of air pollutants regulated by the EPA (p. 546). Regardless of current policy, research shows that carbon dioxide is one of the central gases responsible for global climate change and its increase over time can be attributed to multiple environmental concerns. The following lab will illustrate the dangers of carbon dioxide emissions and provide an introduction to modeling of future outcomes. To complete the lab for this week, follow the steps below:

First, download the Carbon Dioxide Lab Reporting Form. All data will be reported and questions answered directly on this form.
Secondly, open the Carbon Dioxide Lab Instructions, and follow the steps indicated.

When completed, save the Carbon Dioxide Lab Reporting Form as a Word document. No title page or headers are necessary; however, should you utilize any outside resources to complete the questions they should be properly cited according to on the reference page.

ATTACHED IS THE Carbon Dioxide Lab Reporting Form. ALSO THE Carbon Dioxide Lab Instructions,

EVERY PART OF THE CHART MUST BE FILLED AND EVERY QUESTION ASKED MUST BE ANSWERED!!!! ATTACHED IS THE GRADING FOR THIS ASSIGNMENT SO YOU KNOW WHAT IS EXPECTED!!!! ALSO ATTACHED ARE THE RESOURCES NEEDED!!! THE LAB NEEDED IS IN THE RESOURCES!!!! ATTACHED IS PAGE 546 CONCERNING THE EPA !!!! REMEMBER TO CITE WORK

1. If only one half of the terrestrial plants in the world existed in 2100 due to deforestation, what do you predict will happen to the atmospheric carbon levels? Why would you predict this?

Answer =

2. In your simulation, carbon levels between 2010 and 2100 are increasing in most of the pools. Which pool(s) show a decline in carbon over this period and why?

Answer =

3. What is the relationship between an increase in fossil fuel consumption and increased carbon in terrestrial plants? How might this change flora populations?

Answer =

4. What is the relationship between an increase in atmospheric carbon concentration and increased carbon in the ocean surface? How might this change marine life populations?
