The only carbon solution is figuring out how to not need fossil fuels for energy, because there's absolutely no way biological photosynthesis can make more than a tiny dent in that figure.
I'd also look at Canada's abject failure on the 'natural carbon sink' front. Their idea was that Canada's pine forests would somehow serve as an offset for Alberta tar sands fossil carbon emissions (among the highest in the world, as they use gas to melt the tar to process it into syncrude for refineries). Climate change however increased temperatures, leading to pine beetle outbreaks and fires, and those forests became net atmospheric carbon sources, not sinks:
