I highly recommend reading about this first before reacting.
1. It isn't about using the ocean water to make clouds. It is specifically about using the salt as a cloud condensation nuclei (CCN)
2. The concerns about CO2 and noise are well-founded concerns. They aren't intractable, though. For instance, if this really worked, maybe solar powered zeppelins would be the way to go (oh, please let it be so)
3. Unless scientists conduct research like this, we won't be able to answer the rest of your questions. They are empirical in nature.
