Unfortunately this doesn't mean much for the practical problem, because most of that uptake is is dumped into the atmosphere again when the plant dies and rots.
It's like we've got a bathtub where the water level is rising, because we won't turn off the tap and the drain is only so big. We can lower the apparent water-level by throwing in a bunch of plant-sponges, but we can't just keep adding more indefinitely.

If that's true, there would seem to be no benefit to the climate in preserving or regenerating forests.
