Biofuels like wood can be roughly carbon-neutral, since growing them absorbs atmospheric CO2, and burning them releases that same amount of carbon back into the atmosphere.

Though obviously this isn't the case if the wood comes from badly-managed forests that are not replanted. And there are other effects that can make wood fuel carbon-positive:

True, but it doesn't matter. After you burn the wood, you are adding carbon that doesn't need to be there. The physics don't distinguish between carbon that is produced by a short carbon cycle or a long one.
