Does cloud seeding have an impact on the environment? Experts haven’t found any harmful effects of cloud seeding with silver iodide on the environment so far. Some studies have shown an increase in cancer rates and birth defects in children born to mothers who were exposed to silver-containing dust during pregnancy. In addition, some researchers have suggested that silver may be harmful to the immune system. The benefits of using clouds to create rain are many.
For example, clouds can be used to increase the amount of sunlight that reaches the Earth’s surface, which in turn can increase crop yields and reduce the need for fertilizers and pesticides. Another benefit of clouds is that they can act as a barrier to harmful ultraviolet (UV) radiation that can damage the ozone layer, a protective layer of ozone that protects us from harmful UV radiation.

What does silver iodide do to the human body?
Prolonged exposure to iodides may produce iodism in sensitive individuals. Skin rash, running nose, and headaches could be symptoms. For at least 15 minutes, flush eyes with plenty of water, lifting the upper and lower eyelids occasionally. If symptoms persist, seek medical attention. Fluoride is a naturally occurring element in the earth’s crust. It is also found in drinking water and some foods.
(FDA) regulates the amount of fluoride that can be added to the water supply. States, water fluoridation is mandatory for all children under the age of 6, and for those who are at high risk of developing dental fluorosis, such as those with a family history of the disease.
How toxic is silver iodide?
The silver ion is among the most toxic of heavy metal ions, particularly to microorganisms and to fish. Ag is less important as an environmental contaminant because of the ease with which it forms insoluble compounds. Ag is not likely to focus on harmful levels in the aquatic environment. Ag is a major component of the earth’s crust.
Which chemical is used in cloud seeding?
Dry ice, also known as silver iodide or carbon dioxide, is used to supply naturally deficient clouds with the proper concentration of ice crystals to increase precipitation. (NOAA) and the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS) are the primary sources of weather data.
(NCDC) provides data on precipitation, temperature, humidity, wind speed and direction, and sea surface temperature (SST) for the contiguous 48 states. NCDC also provides monthly and annual averages of precipitation and temperature data for all 50 states and Washington, D.C.

What states use cloud seeding?
Within the past two years, idaho, utah, colorado, wyoming, and california have all expanded their cloud seeding operations, with seeding a key plank in the colorado river basin’s water management strategy. “We’re seeing more and more states looking at this as a way to improve water quality and reduce the amount of water that’s lost to evaporation and runoff,” .
Who invented cloud seeding?
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 New York City. His death was confirmed by his son, Vincent J., who said his father had been ill for some time. The cause was not immediately known.
When did cloud seeding start?
The first experiments with cloud seeding took place in 1946, and since then seeding has been performed from aircraft, rockets, balloons and satellites. (USDA) and the National Oceanic and Atmospheric Administration (NOAA) have been involved in the development of cloud-seeding technology since the 1950s. (NSF) is the primary funder of NSF-funded research and development activities in weather modification. For more information, please visit: www.nsf.gov.
What happens to silver iodide in cloud seeding?
When storm systems move through one of our cloud seeding project areas, a solution containing a small amount of silver iodide is burned from ground-based generators or released from aircraft. The silver iodide helps in the formation of cloud droplets when it reaches the cloud.
In addition to cloud-seeding, we are also working with the U.S. Department of Agriculture (USDA) and the National Oceanic and Atmospheric Administration (NOAA) to study the effects of climate change on cloud formation and precipitation. These studies will help us better understand the role of clouds in weather and climate.
Does Texas use cloud seeding?
One of the largest water conservation districts in Texas also conducts cloud seeding operations to enhance rainfall and, thus, augment groundwater recharge over the Ogallala Aquifer. (DSHS) and the Texas Water Development Board (TWDB) are the primary agencies responsible for managing the state’s water resources. DSHS administers the State Water Project (SWP), which is a statewide water management plan for Texas.
SWP is designed to improve the quality and quantity of water available for use by Texas residents, businesses, and agricultural operations.
