Cloud seeding is accomplished by dropping particles of dry ice (solid carbon dioxide) from a plane onto super-cooled clouds. This process encourages condensation of water droplets in the clouds, which usually, but not always, results in rain or snow. From this passage, it's reasonable to assume that:

Cloud seeding could be used to end a drought.
Cloud seeding is prohibitively expensive.
Cloud seeding is rarely used.
Cloud seeding can be accomplished by using regular ice.
