Venus and earth have equal amount of CO2 Earth incorporated CO2 into rock Venus is 30% closer to Sun which is critical point. because it has oceans and carbon dioxide cycle On earth, it is cool enough for water to rain down to Venus is all in the atmosphere because it make oceans in which CO2 dissolved and locked into rocks. As a result, atmosphere left with less CO2. has no oceans and thus no carbon dioxide cycle On Venus,
