11. Are the years with the highest and lowest temperatures the same on both graphs? If not, how much do they differ (i.e., how much time is there between them)?
12. Are the decades with the highest and lowest average temperatures the same on both graphs? If not, how much do they differ (i.e., how much time is there between them)?
13. On average have global temperatures risen or fallen since 1900, and how much have they changed? Does the global data suggest that this trend will continue? Explain your answer.
14. How does the overall pattern in global temperature changes compare with changes in atmospheric CO2 levels?
Part C: The Effects of Global Warming Use whatever resources you have to investigate the biological and environmental impacts of a warming planet. How will species be impacted? Will extinction rates increase? Will precipitation patterns around the globe be altered? 19. Present two changes predicted to occur as a consequence of climate that you think are most significant. Explain what the changes are, and the reason for their importance (in your mind). Provide evidence to support your answer (5 points for each change, 10 points total).
