Quantify with precise percentages the amount of carbon in the atmosphere that is directly attributable to the increase in human population?
Not sure about the first question, but the second question is answered easily enough. It is estimated that the oceans contain 37,400 billion tons (GT) of suspended carbon dioxide, land biomass has 2000-3000 GT, the atmosphere contains 720 billion tons of CO2, and Mankind contributes 6 GT. That's 8/10s of 1 percent caused by Mankind.
