I don't know about Mother Nature, but silicate rich (or carbonate rich) rocks weather by sucking C02 out of the atmosphere (or oceans) and it can apparently be accelerated by spreading crushed rocks on fields or beaches.

I wonder how many tons of biomass in foliage regrows every single year. All that plant matter is primarily carbon by mass, and most of it probably comes from the atmosphere.
