The following figure shows that the amount of carbon dioxide released into the atmosphere by human activities (grey line) and the observed annual increase in atmospheric carbon dioxide (black line) since the 1960's. Which of the following explanations best describes why the observed atmospheric CO2 is so much lower than the emissions? a. the observed CO2 is lower because some of the CO2 emissions escape the atmosphere into space b. the observed CO2 is lower because some of the emissions are absorbed by the ocean and plants c. the emissions line is including other greenhouse gases in addition to CO2 which the data is not accounting for d. the emissions are higher than the observed atmospheric CO2 because it is including volcanic eruptions and wildfires
