The other thing with trees is that they aren't permanent carbon sinks in the way that coal underground is.
Wood will eventually rot or burn and release it's carbon.
Human beings have taken carbon in the form of hydrocarbons underground and released is into the C02 - O2 cycle in the air. The main way to solve this would seem to be putting it back into the ground. So, reverse coal-mining? Turning wood into charcoal and burying? These seem like necessary counter-parts to simply growing trees.
I think you're overstating the problem with carbon released from decaying wood.
Trees newly planted now will net-absorb carbon for the next 50-100 years, exactly the time period when we need to bring the carbon balance under control until we have our energy used cleaned up and other technologies developed. When the newly planted forest matures, trees fall and rot, but new growth takes their place. So it doesn't release a large amount of carbon, but enters a steady state roughly carbon-neutral.
