We need all-of-the-above. Yes, we need to cut CO2 -- to net zero. And that (likely) requires large-scale systemic change. The big step there is pricing carbon. Not the only step. http://www.nature.com/news/energy-policy-push-renewables-to-spur-carbon-pricing-1.18260

But it's also clear that solar geoengineering tackles aspects of the problem that cutting CO2 does not.
