But until recently, the science didn’t quite back this practice up. In large part, that’s because operational cloud seeding programs don’t have the luxury of conducting controlled tests — they have an obligation to produce as much rain as possible for the people living under the clouds they seed. But there’s been a new breakthrough. In 2017, a major cloud seeding experiment in the mountains of Idaho showed that cloud seeding works; shooting chemical flares into the sky does produce more precipitation. As the world faces an increasing number of heat waves and droughts, banking water is becoming more and more important. And while we don’t know ...
