Humans are actually producing more carbon dioxide than natural sources can absorb. That means the atmosphere is not at a steady state. Scientists and engineers are researching ways to remove carbon from the atmosphere faster than the current rate. This process is called carbon sequestration. If humans increase their rate of carbon emissions but also increase the rate of carbon sequestration by the same amount, what effect will that have on the residence time of carbon dioxide in the atmosphere? What effect will it have on the total amount of carbon dioxide in the atmosphere?
