Answer:

Around 25-30 gigatons.

Explanation:

Although natural processes do produce much more carbon dioxide than humans, its a delicate balance and all of that carbon dioxide is absorbed back. However, when humans arrived, they disrupted that balance, and even with the relatively small amount it is creating big problems.
