A Spectrum of Applications:
Despite the complexities, cloud seeding boasts a diverse range of applications:
The Ethical and Environmental Debate:
The Future of Precipitation Control:
Cloud seeding chemicals may be dispersed by aircraft or by dispersion devices located on the ground (generators or canisters fired from anti-aircraft guns or rockets). For release by aircraft, silver iodide flares are ignited and dispersed as an aircraft flies through the inflow of a cloud.
Does Cloud Seeding Have an Impact on Health and the Environment? So far, experts haven't found any harmful effects of cloud seeding with silver iodide on the environment. The concentration of silver in a storm from cloud seeding is far below the accepted limit of 50 micrograms per liter.
India, China, Thailand ,Indonesia are some of the countries trying this method.
Within the past two years, Idaho, Utah, Colorado, Wyoming, and California have expanded cloud seeding operations, with seeding a key plank in the Colorado River Basin Drought Contingency Plan
The silver ion is among the most toxic of heavy metal ions, particularly to microorganisms and to fish. The ease with which Ag forms insoluble compounds, however, reduces its importance as an environmental contaminant. Ag is not likely to concentrate to harmful levels through either terrestrial or aquatic food chains.
The scientist added: “The method can lead to acidification of the oceans, ozone layer depletion and an increase in the levels of atmospheric carbon dioxide. Silver is a heavy, toxic metal and it harms the health of plants, humans and animals. Cloud seeding is also a costly method.
What Are the Benefits of Cloud Seeding?
[1] Create more winter snowfall and lead to more mountain snowpack.
[2] Enhance the natural water supply to communities.
[3] Lessen hailstorms by reordering water vapor in clouds, which breaks down large hailstones.
A cloud seeding program in the region could cost $27 to $214 per acre-foot of water in a low cost scenario and $53 to $427 per acre-foot in a high-cost scenario. While the report's results might seem small, they are more promising and extensive than any other cloud seeding experiments have been before.
The problems and risks that may result from transitioning to a low-carbon world, such as unwanted ecological modifications, ozone depletion, continued ocean acidification, erratic rainfall patterns, rapid warming if seeding were to be halted abruptly, airplane effects, and more, are not necessarily severe enough to outweigh the need to keep temperatures down.
