How can you add 550 to something but it only increases by 15?

I have no overview over numbers. But the CO2 houshold is a dynamic thing. We do not only have sources of CO2 (natural and human), we also have consumers that take CO2 out of the atmosphere.
The difference between both amounts to the increase of CO2 in the atmosphere. As largest consumer of CO2 there is to count the algal life in oceans. They bind huge amounts of this gas. Far smaller but also significant is also the storing of CO2 in trees.
