Over time it would gradually remove CO2 since not all of it goes back, but stuff like this isn't even a rounding error compared to the amount of CO2 we'd need to remove.

Planting billions and billions of trees would pull a lot more, but still would only make a small dent. Greening large desert regions with large scale water and local climate engineering projects, ocean seeding, etc. would also pull more but still only make a dent.
