Only two?? There are quite a few. Two of the largest ones are volcanic eruptions and decaying vegetation. The main anthropomorphic one is burning hydrocarbons.
Explanation:
The atmospheric concentrations of carbon dioxide have changed over time, and drastically over geologic time! Equilibrium (changes resulting in a perceived steady state) shifts between different stable configurations. Venus and Mars as well as Earth have a particular state of equilibrium with respect to CO2 in their atmospheres.
