The colder oceans are notable natural CO2 absorbents, plus we have to mention the effects of life itself: photo-synthesizing plants and unicellular creatures. Like the historical ones that fixated enough carbon to create today's wast coal, oil and methane fields.

As I recall, there is a group of creatures that may did the first big wave of carbon fixation at the beginning of life, binding CO2 and releasing the important O2 that enabled the appearance of complex life forms, but I can't remember it's name.
