Interestingly enough, a side effect of CO2 emissions IS reforestation. Earth is getting greener because of increased CO2 in the air. What is not obvious though, is if this is going to make the problem worse. For one, the green albedo is often darker than what was previously in place, and retains more heat. However, obviously a fair amount of that energy presumably goes towards photosynthesis. Trees also tend to bring a fair amount of water into the atmosphere, however, and water is actually one of the most aggressive greenhouse gasses in terms of its capability to retain heat. TL;DR, carbon capture is very important, and planting trees is probably a good thing, but there's a fair amount of debate.
