If the atmospheric burden of CO2 increases by 18.0 Gt (gigatonnes, 1Gt= 1 x 1012 kg) over a given period of time, starting now, and the current atmospheric CO2 is 408.3 ppm, what will the concentration of CO2 be (in ppm) after this increase? (Assume a total atmospheric mass of 5.10 x 1021 g and an average molar mass for air of 29.0 g/mol)
