Thus would more sunlight be [snip] I once saw a program on cloud seeding. The best results appear to have been obtained downwind from a paper factory because the smoke released through the chimney contained salt particles which drifted up into the bottom of the clouds. IOW the method proposed above may only succeed in increasing rainfall from the clouds. If anything, the effect would be counter productive, shortening the life span of the clouds.
