That's pretty much the problem, but I should also add that this doesn't mean we shouldn't do reforestation. It just means there isn't a single solution to a complex global problem (honestly, is anyone surprised? Why the fuck are people suggesting single solution answers to complex nuanced problems?).
We should be making larger forests, fill them with birds and animals (this is actually a difficult part if you look at huge man made forests like the one in China). But we should also use man made sequestration. We should also redevelop coral reefs around the world. Etc. A lot of people seem to be forgetting the heart of the problem. There is too much greenhouse gases in the atmosphere. It doesn't matter how we remove them, just that we do (assuming the removal process doesn't do more harm, of course). Doesn't matter if it is natural (i.e. forests & reefs) or artificial (CCS), it needs to be removed from the atmosphere (and ocean). There's no "one size fits all" solution.
