The carbon model is the flow and the movement of the carbon and its compound in the atmosphere. Climate change is the limitation of the carbon model. 
<h3>What is climate change?</h3>
A climate change is a variation in the weather and the climate pattern due to a change in temperature and other atmospheric factors. It will lead to a transformation in the flow of carbon in the environment.
Increased carbon in surroundings increases temperature and results in a change in seasons and humidity levels, leading to changes in the rainfall. 
Therefore, climate change is the limitation of the carbon model.
