In reality, controlling the weather is impossible. We can, however, influence it, and we've been attempting to do it for some time. Various efforts, from hail cannons to stopping hurricanes, have been tried or proposed over the years, to say nothing of the incidental effect of our use of fossil fuels. Perhaps the most popular attempt at geo-engineering, however, is cloud seeding.
Cloud seeding is the process of combining different kinds of chemical agents — including silver iodide, dry ice and even common table salt — with existing clouds in an effort to thicken the clouds and increase the chance of rain or snowfall. The chemicals are either shot into the clouds or released by flying near and into the clouds.
Cloud seeding is a process of aiming chemicals into clouds to induce more rain and snow to fall.
