Well, the study considers already existing forests. Is it feasible to eg. increase global forestation by 100% to offset 60% of emissions? Not sure. Also, it considers a limited timespan. While it is not that relevant for undisturbed forests that usually have a stable ecosystem (trees born and die gradually), it may be an issue with disturbed ones; trees will tend to have about the same age and the same duration; this will cause release spikes related to decomposition. Also, "planting trees" usually is a placeholder response that largely ignores the impact of monocultures in the soil, subterranean water reservations and propagation of forest fires, plus the fact that co2 tends to concentrate higher in the atmosphere, way above the average tree line. In summary: its not as bad as I thought when I wrote the previous reply, sure. But it is still far from feasible.
