As I understand it, the most efficient, scalable, and long-term effective climate solution remains olivine carbonation as proposed by efforts like Project Vesta [0]. I take the point that any and all solutions should be explored at this time of critical importance, but there's a risk that sexier, more high tech approaches gain disproportionate momentum for reasons separate from the science. Is there an obvious explanation for why this or other geoengineering schemes haven't taken a leading role either in the discourse or implementation of carbon capture and sequestration?
