This extra carbon dioxide is lowering the oceans ph, through a process called ocean acidification. Every time you breathe, you are part of the carbon cycle because you are exhaling co2.
The conversion of carbon dioxide is started by the fixation of carbon. If we add to our steady state model the co 2 emission history for the last 100 years, we should end up with a carbon cycle in a state very similar to todays.

Carbon enters the atmosphere through natural processes such as respiration and industrial applications such as burning fossil fuels. No wonder the natural cycle of carbon reactions here on earth has become of such great importance. In all four processes, the carbon dioxide released in the reaction usually ends up in the atmosphere.
Through following the carbon cycle we can also study energy flows on earth, because most of the chemical energy needed for life is stored in organic compounds as bonds between carbon atoms and other atoms. Carbon dioxide is also the gas we exhale, since it is the product of respiration, whereby oxygen atoms are used to burn oxidise the foodstuffs to release the energy necessary to sustain life.
