Well, maybe. If greenhouse gas emissions do not start coming down very soon, there will inevitably come a "point of no return" at which climate change enters a runaway feedback loop. If we haven't reached that point yet, then there is still a chance to bring carbon dioxide levels down, but it would need to happen through photosynthesis on a massive scale.
