a.Determine the net change in growth rate between 1975 and 2008. Compare this figure to the slope of the trendline. Explain why the slope of the trendline is different than the actual net change in growth rate between 1975 and 2008.
b. Use the trendline to predict the mean CO2 growth rate for 2050, assuming global trends in CO2 emissions at Mauna Loa do not change. Describe two likely consequences to Earth’s environment if your prediction reflects global trends through 2050; at least one consequence should emphasize changes to Earth’s biodiversity.
c. Identify and describe two factors that likely added CO2 to the global atmosphere during the time period shown on the graph. One factor should be natural and one factor should be anthropogenic. Identify and describe two factors that likely removed CO2 from the global atmosphere during the time period shown on this graph. One factor should be natural and one factor should be anthropogenic.
d. Identify a treaty or piece of legislation relevant to atmospheric CO2 and explain how this treaty or piece of legislation helps slow or reverse trends such as those shown in this graph.
