It is called "carbon cycle" for a reason.

No amount of trees or other biomass can revert what we have done or even make a significant dent.

Currently, all biomass on Earth equals about a decade of our emissions from carbon we dug out. Even doubling all biomass, which is impossible to do, would only be roughly equal to pausing our emissions for a decade.

That is, assuming all that biomass does not revert into carbon through fires and other ways.
