BECCS is probably the most realistic option:

... because removing carbon from 99% pure flue gas is a lot easier than removing carbon at 400PPM from the atmosphere.
Even if every bit of farmland on the planet was growing sugarcane for BECCS, we still would only pull ~9GT/y out of the atmosphere, on par with our current net emissions.
Of course, solving climate change is not actually a difficult problem. A $50/ton carbon tax would make all of these things profitable, including CCS on existing natural gas plants.

- credit_guy 10y agoWhat is your take on phytoplankton?
- chris_va 10y agoUnfortunately I am not the right person to ask on phytoplankton, but the main concern I have is about geologic stability. Noteably the percentage of the bloom that actually stays out of the food chain. The models for this, when I spoke with some oceanography folks, were still really fuzzy.

- jsingleton 10y agoCarbon Capture and Storage (particularly on biomass) appears to be one of the more realistic solutions. So it was a huge shame when the UK Conservative government cancelled planned investment in CCS (breaking a manifesto promise in the process). It's not a technical or economic problem. It's a political and social problem. https://www.theguardian.com/environment/2015/nov/25/uk-cancels-pioneering-1bn-carbon-capture-and-storage-competition https://www.theguardian.com/environment/2015/nov/25/uk-cance... https://www.theguardian.com/environment/2016/jul/20/treasury-cut-carbon-capture-storage-cost-uk-30bn https://www.theguardian.com/environment/2016/jul/20/treasury...
