What is cloud seeding? Here’s what it can—and can’t—do to the weather
In the wake of disastrous floods in Texas, concerns about cloud seeding technology have run rampant. The technology sounds fantastical—like the doings of a comic book villain—but scientists say the real impact of the technology is less than nefarious. Today, cloud seeding is most common throughout the western United States. Research programs in mountainous states such as Wyoming and Colorado are focused on studying how seeding clouds can increase the odds of snowfall. … A 2017 research program, dubbed SNOWIE and funded by the National Science Foundation, was the first to quantify the effect of cloud seeding. It found that cloud seeding could successfully generate snow that might not have otherwise fallen. … Scientists remain adamant that this controversy is spurred by a misunderstanding of what particles introduced into clouds can do.
