What is the fate of CO2 produced by fossil fuel combustion? part of Quantitative Skills:Activity Collection
The carbon dioxide concentration in the atmosphere is increasing as a result of combustion of fossil fuels. However, the observed atmospheric CO2 increase rate is only ~60% of the CO2 loading rate due to fossil fuel combustion. Why? We will answer this question using a box-model to simulate the earth's carbon cycle. The model will hindcast the atmospheric CO2 increase during the industrial era and compare it to the historic observations of atmospheric CO2 concentrations. The model will then be used to forecast future concentrations of atmospheric CO2 during the next century.
