Can we really prevent all warming for less than 10B$ with the mostly side-effect free geoengineering technique of Marine Cloud Brightening? proposes using crushed olivine to capture carbon and reduce ocean acidification. It seems doable on a large scale and not very expensive.

Another comment [] claims that this would be relatively expensive. (reason for retraction: Occurred to me that I'm not sure how this compares in cost to other carbon capture and anti deacidification measures)
