Cloud Seeding

Cloud seeding has been the most commonly used technique in weather modification.  In addition to cloud seeding, many other terms are also used, including man-made precipitation enhancement, artificial weather modification, rainmaking and so on. Cloud seeding sprays small particles, such as silver iodide, upon clouds in order to increase precipitation. It has been used in a variety of drought-prone countries, including the United States, China, India and Russia. In the Rocky Mountains, Sierra Nevada and other mountainous areas of the United States, cloud seeding has been employed since the 1950s. China has had a perceived dependency upon cloud seeding in dry regions (see Section 7.4 for more details).

“The major hazards encountered in the use and handling of silver iodide stem from its toxicologic properties. Toxic by all routes (ie, inhalation, ingestion, and dermal contact), exposure to this odorless, light yellow, crystalline substance may occur from its use in seeding clouds for rain-making…”

The question is not that is cloud seeding harmful, but how harmful. It is obvious that it is significantly harmful. So far, programs such as PGCD have not provided effective monitoring and sampling to demonstrate that the silver concentrations in the water and soil caused by cloud seeding are at “safe levels.”
