I don't know about carbon capture, but I do think we should be researching sulfur aerosols and iron fertilization. See Oliver Morton's excellent book The Planet Remade.
I'm betting on sulfur aerosols. The energy requirements are modest, the impact is apparently relatively reversible, the side effects seem less potentially catastrophic than iron fertilization.
I look at the street outside my office and simply can't picture us deploying enough carbon capture machines to offset how much we're pumping into the air. I hope I'm wrong.
