I believe that a solution exists, if in fact CO2 induced global warming is sufficient to warrant it. The latest IPCC report has a range of possible warming which is innocuous at the low end. It's also not clear what the error bounds are on the published warming estimates.

I gave the concrete example of orbital sunshades, which are absolutely feasible given current engineering techniques. Another possible CO2 mitigation are iron-induced ocean algae blooms. Many other approaches have been suggested including nuclear powered CO2 sequestration in the Antarctic. I'm sure that many other innovative, technology based mitigations will be proposed over time.

I hope that clears things up for you.
