Geo-engineering — the various processes by which the weather is intentionally altered — is a growing concern, not just here in America but across the globe. Many wonder if practices like cloud seeding, where silver iodide or dry ice is dispersed into clouds to induce precipitation, or solar radiation management, where aluminum oxides or sulfates are injected into the stratosphere to reflect sunlight and reduce global temperatures, risks meddling with cosmic forces we can’t even begin to fully realize.

“Geo-engineering really scares me because it seems like we're starting to play God,” says Glenn Beck .
