I can imagine growing massive hydrogen balloons in the sea. Using their solar energy and the day-night cycle, they pump small amounts of salt water to approximately 100m high, where the salt seeds cloud formation. Forming low clouds over dark blue oceans is very efficient.

If we do that kind of thing on a massive scale, we could use that not simply to reduce the global temperature, but to control the local weather, reducing area covered by deserts.

  Yeah, I think local weather control, say over melting permafrost, is a high priority.
