Image of a graph showing the Mauna Loa CO2 Concentrations. Please have someone assist you with this.

This graph of the CO2 data from Mauna Loa has two notable features; a general rise in CO2 concentration of about 14% from 1958 to 1995 and an annual cyclical variation superposed on the rising curve. Many sources have been proposed to account for the features of the CO2 data, including industrial pollution, volcanic eruptions, seasonal changes in vegetation, and biomass burning (natural and human-caused). This set of activities provides the information you need to evaluate the importance of some of these sources of CO2 in accounting for the observed CO2.
