To prevent possibly catastrophic climate change we can't just bring C02 emissions to zero - we have to go negative, sucking the CO2 that's already there. The best tech is a billion years old: trees.

I wonder how much extra efficiency synthetic biology might achieve here. The basic cost-benefit already seems pretty good: 6 years CO2 (or 20ppm) for $300 billion is very inexpensive compared to (say) the EPA's estimate for the cost of the Clean Air Act in the US.
The article claims 205 GT is 2/3 all the CO2 generated by humans since the industrial revolution. I think they mean Carbon in CO2, not CO2. Seems like a pretty bad error, and I wonder what else is wrong in the SciAm article? Presumably not in the source.

Mmm. I haven’t read the sciam article and the original paper is queues for me to read later today, so I will look at those claims in more detail.
