Hi I need to calculate how long it would take to reestablish the world from its 2020 polluted atmospheric carbon dioxide levels to its state 100 years back. I used a simple formula (CO2 removal rate (bmt/year) = (initial CO2 emissions - final CO2 emissions) / time period (in years) however, my teacher says it is too little math, the IA needs more. I don't know what formula or calculation I can use. Can someone help me please.
