ABC on ‘Cloud Seeding’ Boom: ‘We’ve Been Doing This Since the 1940s’

EXCERPT:

REPORTER: “Ginger, this is such a cool concept, but is it too good to be true? I mean, how do we know that the chemicals that they’re spraying from the air aren’t bad for us or the planet?”

ZEE: “The good news is we’ve been doing this since the 1940s and ‘50s. Other countries do it, and there have been a lot of research projects that have shown that the silver iodide, for example, is not found. It’s negligible once it gets down to ground level.”
