The graph shows atmospheric CO2 levels recorded by the Mauna Loa observatory in Hawaii. The graph also shows three major volcanic eruptions between 1960 and 2000. Aerosol stratospheric optical thickness is a measure of volcanic activity. a graph showing a steady rise in CO2 levels measured at Mauna Loa, Hawaii, from 1960 through 2000 and a graph showing volcanic activity, including three major eruptions, during the same time frame Based on the data in the graph, do you think that these volcanic eruptions were the main contributor to the change in overall CO2 levels at the station? Explain your answer.
