If we’re adding 8 Gt/yr of C to the atmosphere, and the atmosphere reservoir size is 800 Gt, what is the per year increase in pCO2 (in ppm)? Remember, present pCO2 is 400 ppm A)  10 ppm per year B)  8 ppm per year C)  6 ppm per year D)  4 ppm per year E)  2 ppm per year If we’re adding 8 Gt/yr of C to the atmosphere, and the atmosphere reservoir size is 800 Gt, what is the per year increase in pCO2 (in ppm)? Roughly… 800 Gt = 400 ppm. Therefore 1 Gt = 0.5 ppm. 8 Gt/yr * 0.5 ppm/Gt = 4 ppm/yr If we’re adding 8 Gt/yr of C to the atmosphere, and the atmosphere reservoir size is 800 Gt, what is the per year increase in pCO2 (in ppm)?
