5. Who is Charles David Keeling, and what did he measure and describe?
6. Why does the Keeling Curve rise and fall annually?
7. Why are scientists concerned about the loss of glaciers?
8. How do scientists measure atmospheric CO2 concentrations and obtain estimates of temperature from periods up to many hundreds of thousands of years ago?
9. Is there a correlation between atmospheric CO2 concentration and temperature? If so, scientists must describe whether or not there is causation. Describe any known factor(s) about these variables that provide supporting evidence of causation.
10. Give at least two pieces of evidence (supported by data) that support the hypothesis that Global Warming is occurring.
11. Describe the relationship between oceanic water temperature and the wind velocity and water content of storms.
12. How might climate change affect different regions of the planet almost paradoxically in different ways?
13. Describe the environmental consequences of the loss of permafrost.
14. Why are arctic ice caps melting so quickly? How might ocean current conveyors be affected by the rapid loss of ice caps?
15. Where is the Larsen B Ice Shelf, and what happened to it in 2002?

17. From the data of the United States DOE Energy Information Administration, which country has the largest carbon emissions per person per year?
18. When a random sample of 928 peer-reviewed scientific journal articles on climate studies was taken during a study published in Science, how many of these were found to be in disagreement with the global consensus that greenhouse gas pollution has caused most of the warming of the past 50 years?
19. List at least four things you can do to reduce your individual contribution to carbon emissions.
20. Despite your answer to question #3, do you consider this documentary to be an overall reliable source of information about Global Warming? Why or why not?
