@jsalsman it is just a bandaid for carbon emissions though. It probably can't displace more than 50 - 100 gigatons / century continuously.

@DanielleFong the only non-bandaid I can think of would be http://talknicer.com/co2extraction.pdf … at $50/tonne (liquid phase much more efficient than air) -
@jsalsman CO2 extraction from seawater is rate limited by shallow water absorption rates. The other major problem is who pays for it. - 2 more replies

@DanielleFong what source are you using for numbers? Looking at http://www.foreignaffairs.com/articles/64829/david-g-victor-m-granger-morgan-jay-apt-john-steinbruner-and-kat/the-geoengineering-option … all carbon could be offset by two Stratotankers/day -
@jsalsman http://en.wikipedia.org/wiki/Stratospheric_sulfate_aerosols_(geoengineering)#cite_note-ReferenceA-6 … -- 20 years of grace period. That's about 500 - 600 gigatons total. But, lifespan only several years. - 1 more reply
