I have a related question. You say that the oceans and plants can only absorb 40% of the "human caused" CO2. Presumably then, they are reabsorbing all the other sources of CO2, and are then nearly saturated. Now I often read statistics that quantify the amount of CO2 humans are adding as "X number" of tons of CO2, and planting trees is a popular way to boost the capacity of that carbon sink. But how much CO2, in "X number" of tons (pounds?), does a tree, or a thousand trees, absorb? Do we know?
