- Which of the following is correct about the carbon cycle? Three hundred years ago.the amount of CO_(2) flowing into the atmosphere was equal to the amount flowing out of the atmosphere. Today the amount of CO_(2) in the atmosphere is increasing because the ocean and plants currently absorb about half of the CO_(2) from human activities. The removal of CO_(2) gas from the atmosphere resulted in increased global temperature since 1980. Today more CO_(2) is coming out of the atmosphere than is going into the atmosphere. Today burning forests reduces the amount of CO_(2) gas released into the air. Three hundred years ago human activity contributed to a large amount of CO_(2) flowing into the atmosphere.
