I think that this mechanism is mostly CO2 being slowly weathered out of the atmosphere and disposed of, mostly via limestone formation. This takes a very long time and is very slow, so it can only catch up if you stop pumping it out.
- agapos 12y agoThe 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.
