Back in 2018, an Iranian general put forth a theory about the country's drought: Israel was stealing Iran's clouds. He later walked back on the comments after Iran's own meteorological organization contradicted him, according to state media reports.

Social media posts with millions of views reference a "weather war" and point to dams being filled and highways blanketed in snow as proof of climate interference in the region.

The viral conspiracy theory focuses on a technology called cloud seeding and a facility in the United Arab Emirates called the Research Program for Rain Enhancement Science.

So what's the truth? Can a country really make it rain across borders?…
