Tree planting might be able to offset some several percent of fossil fuel use. For the rest, the only option is to not keep burning that fossil fuel. Apart from tree planting, technical processes of removing carbon from the atmosphere require a ridiculous amount of energy (and much more than the useful energy we got from burning the fossil fuel that released that carbon in the first place), and we're really going to need all that green energy for replacing fossil fuel usage, so carbon capture technology isn't really a serious answer either.
