The total annual CO2 budget of the earth is tremendous; less than 5% of CO2 emissions each year into the atmosphere are from humans. Volcanism, photosynthesis, and other natural sources outweigh humans by far. In numbers, ballpark 730gigatons from natural sources and about 30gt from humans.
If you look at the amount the CO2 levels increase each year in the atmosphere, you'll find that they net increase by 16gt per year or so.
Implying that if we ceased all human CO2 emissions, the atmospheric levels would start recovering at around half the rate they're currently increasing.
