Risks or concerns like unwanted ecological changes, ozone depletion, continued ocean acidification, erratic changes in rainfall patterns , rapid warming if seeding were to be stopped abruptly, airplane effects, to name a few, may just not be bad enough to override the imperative to keep temperatures down.
Vincent J. Schaefer , a self-taught chemist who invented cloud “seeding” and created the first artificially induced snow and rainfall, died on Sunday at a hospital in Schenectady, N.Y. He was 87 and lived in Rotterdam, N.Y. Mr.
One source has is that the son of King Sejong the Great , a member of the Choson Dynasty who reigned from 1418 to 1450, invented the first rain gauge. King Sejong sought ways to improve agricultural technology to provide his subjects with adequate food and clothing.
In the winter of 2018-2019, water managers in Colorado said their central mountains cloud seeding program produced between 80,000 and 90,000 acre feet of water at a cost of $2.70 per acre foot —a bargain in a region where prices per acre foot can reach $30,000.
Silver iodide or dry ice (solid carbon dioxide) is used to supply naturally deficient clouds with the proper concentration of ice crystals to increase rainfall through the ‘cold rain’ process.
Silver iodide, the material used in cloud seeding, is toxic to aquatic life . So precipitation from seeded clouds can harm the environment. In response to these concerns, scientists have tested nontoxic replacements for silver iodide. They have found calcium chloride to be effective.
The UAE oversaw more than 200 cloud seeding operations in the first half of 2020, successfully creating excess rainfall, the National News reported. There have been successes in the U.S., as well as China, India, and Thailand.

Cloud seeding is a weather modification technique that improves a cloud’s ability to produce rain or snow by artificially adding condensation nuclei
Find the average volume of rain = Depth x radius x radius x 3.14 . Find the area at the top of the bucket (this is the area over which the rain is collected). Divide the rainfall volume by this area to get the rainfall.

The first experiments with cloud seeding were conducted in 1946 by American chemist and meteorologist Vincent J. Schaefer, and since then seeding has been performed from aircraft, rockets, cannons, and ground generators.
