The increase of atmospheric CO2 is one of the most publicized potential culprits causing global warming. One of the best records of atmospheric CO2 has been taken continuously since 1958 at the summit of Mauna Loa on the big island of Hawaii. This site, at an elevation of nearly 14,000 feet and far from possible local contamination, is considered one of the most favorable in the world for measuring regional atmospheric CO2 concentrations.
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 (both natural and human-caused). This set of activities provides the information you need to evaluate the importance of some of these sources of CO2 concentration data.
