Yes, but what about the ecological consequences? Algae blooms are
complicated things, and influence a lot of other systems. I think we have
to develop a new technology, ecoengineering, to deal with deliberate
modifications of ecology, climate and other aspects of the environment.
Maybe we could start algae blooms in the tropical "desert" seas, where
normally very little life lives?

Well, if you lived on Cuba you would probably think it was reasonable.
Besides, I got the impression the results were rather inconclusive.

My guess is that it is easier to influence systems with no strong
positive feedback loops, especially chaotic ones. Hurricanes seem to be
rather stable structures. Of course, if we can set up our own feedback
loops (as with algae blooms), then we can get interesting abilities.
