Hi

How do you convert, rather calculate the rise in atmospheric concentration of CO2 by emission of 1GtCO2 (=gigatonne). Is the below approach correct, I am not sure. Could anybody advise, please. I think what I have done below is wrong.

1PPM CO2= 2.12 GtCarbon ( IPCC and Gilbert Masters)

Therefore IGt Carbon= 1/2.12= 0.47ppm CO2

1 tonne Carbon=3.66 tonne CO2

therefore 1tCO2=1/3.66=0.27 tonnes carbon ( conversion factor)

so 1Gt CO2=0.27 GtCarbon

1 GtCO2 emission =0.27/2.12=0.127 PPM of CO2 rise in atmosphere
