Not really. A big part of the issue is fossil fuels. These are essentially vast amounts of carbon from millions of years ago that we are digging up and pumping into the atmosphere. Burying trees is not the answer, not digging up the old ones and not burning them would help a lot. Also, bury trees and you bury the nutrients they use to grow, locking them away from the next generation of trees and plants. To plant, grow, cut down and bury trees on any scale you also require machines ... that run on fossil fuels.
