South Korea Floats Artificial Rain Project With China
President Moon Jae-in has proposed a joint effort with Beijing to tackle his country’s fine dust pollution by creating rain over the Yellow Sea. Dust pollution in Seoul has sparked alarm this week, reaching particle concentration levels four times higher than what the U.N. considers healthy. Some believe China is a significant source of that dust.
How will they make it rain? China already uses cloud-seeding, where water-attracting substances are injected into clouds, but it doesn’t always work: South Korea’s last such experiment in January failed.
