The problem with most of these schemes is the power needed to take CO2 and do, well, anything really with it. Solar power need energy to build the panels, install them etc. Nuclear has its own issues. The best thing to do is plant forests. There is now a plan in motion to plant a line of trees along the border of the Sahara to stop desertification. This like of trees will do more than any of these other ideas, is cheaper, and has more secondary benefits.
