Unintended consequences are a bitch. How can people smart enough to "design" these types of projects be so arrogant?
Even removing the co2 that we've added to the atmosphere and sequestering it may not be free of negative consequences. That is the magnitude of uncertainty we need to be discussing and debating. At this point, blocking the sun is just crazy, and not because of feasibility, constructibility, or cost.
Edit: Look at the disaster of updating the Washington DC water system for a supposed "fully understood" lead mitigation project that went unbelievably wrong, because of bad assumptions and factors not initially considered to relevant (unknown unknowns). And there was no controversy over such a conservative "fix" (other than maybe cost given necessity).
