What the Evidence Shows
The claim that the Texas floods were a result of cloud seeding and weather manipulation is not supported by credible evidence. While Texas does issue cloud seeding licenses, scientific consensus and officials, including Senator Ted Cruz, have stated there is zero evidence that such processes can create or worsen storms or cause flooding. Multiple sources highlight that the conspiracy theories linking weather manipulation to the floods are false and have been spread amid political blame and misinformation.
The flooding was a natural disaster, and accusations of deliberate weather modification are unfounded. These conspiracy theories have been debunked by fact-checkers and news outlets, emphasizing that the floods were not artificially created or exacerbated by any known weather manipulation technology.
