Far beyond experimental but not widely reported, weather modification today is anchored not only in science but is an ever-growing practice, both here in the United States and a number of countries worldwide. From agricultural operations and ski resorts to water suppliers, the increasing application of weather modification tools to generate rain and other forms of precipitation has multiple environmental, economic, and policy implications. Amy’s presentation at the 2015 WaterSmart conference provided an overview of the history and science of weather modification, the scope of “rainmaking” today, and its future implications for water supplies and demand, among other issues.
