What's wrong is that we have no real reason to believe that he can, in fact, build a working lifeboat from scratch in time -- or that we can, in fact, intervene in the planet's climate on a vast scale without disastrous consequences -- yet right now, those benefiting from inaction are already using the idea of possible lifeboats as an argument against fighting the fire, so to speak, with the idea being that since cutting emissions is "unrealistic" it's good we have a back-up strategy.
This is not good science, and it's not good science policy. At very least, serious proponents of geoengineering need to acknowledge the severe limitations on our actual knowledge of geoengineering, and point out that emissions reductions are a far more certain and safe approach.
