The problem is that as I understand it the atmosphere has multiple zones or layers. The CO2 gets up into the higher layers where it will not easily be cycled down to where trees can reach it for hundreds of years. And as someone else noted more wildfires plus the release of deep ocean methane sheets which are going to front-load a lot of the heating for climate change but be gone significantly ahead of the time the carbon starts to cycle out. Replanting trees while good is nowhere near enough. We must get carbon emissions massive down and not in 15 years but in less than 10. All planting trees can do is slightly delay the entry of more carbon into the atmosphere to buy a little more time but you'd have to plant a lot for little effect and the developed countries that are reckless enough to continue spewing CO2 at high rates with no plan for reductions are not going to be the ones spending hundreds of millions planting trees.
