Is cloud seeding bad for the environment?
Is cloud seeding bad for the environment?
Impact on environment and health However, there have been several detailed ecological studies that showed negligible environmental and health impacts. The toxicity of silver and silver compounds (from silver iodide) was shown to be of low order in some studies.
What is cloud seeding and how does it work?
Cloud seeding involves modifying a cloud’s structure to increase the chance of precipitation. Cloud seeding adds small, ice-like particles to clouds. Unattached supercooled water vapour molecules in the clouds condense around these particles. Then, the condensed water vapour droplets group together.
Can man make it rain?
Yes, humans can actually modify the weather and it’s been going on for decades. Here’s the lowdown on how cloud seeding works.
Why don’t they cloud seed in Australia?
In Australia, these are usually orthographic clouds – formed by mountainous terrain forcing air upwards. So you need mountains to make it rain as well. And those mountains must be located in a pristine atmosphere, so cloud seeding to put out bushfires is also not an option.
What are the side effects of cloud seeding?
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.
What is Glaciogenic cloud seeding?
The idea behind glaciogenic seeding is you take tiny little drops of super-cooled liquid water that are not growing efficiently enough to become rain drops and you convert them to ice by adding silver iodide. This then helps the super-cooled water grow into snowflakes or raindrops ready to fall from the sky.
How effective is cloud seeding?
Other recent studies have used computer modeling to estimate the increase in snowfall from cloud seeding. A 2014 study across two Wyoming mountain ranges found that cloud seeding could increase snowfall by 5 to 15 percent — but only when the right conditions for seeding were met, or during 30 percent of snow events.
What chemicals are used for cloud seeding?
The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide) and Liquid propane.
What is the purpose of cloud seeding?
Cloud seeding is the process where substances like dry ice and silver iodide are put into clouds in an attempt to make precipitation fall. Cloud seeding has also been used to dissipate fog and weaken some storms.
Who invented cloud seeding?
Vincent J. Schaefer
How long does cloud seeding take?
How long after seeding before a treated cloud starts to change? Seeding effects can range from almost immediate to up to 30 minutes depending on the seeding delivery method (direct injection at cloud top, or base seeding – releasing seeding agent in the updraft below the cloud base).
What is artificial rainfall?
Rainmaking, also known as artificial precipitation, artificial rainfall and pluviculture, is the act of attempting to artificially induce or increase precipitation, usually to stave off drought or the wider global warming.
How do you attract rain?
How to (Try to) Make It RainSeeding the Sky. The most widely used weather-modification technique is probably cloud seeding, which involves priming clouds with particles of silver iodide. Rain Rockets. Airplanes aren’t the only way to seed clouds. The Atmosphere Zapper. Ice-Breaking Booms. Riding the Lightning.
Can rain be created?
Farmers have long wished they could control the rain, and now weather manipulation can do just that. Cloud seeding, the most common way to modify weather, involves shooting silver iodide or other chemicals into clouds to encourage precipitation. In other words, a silver bullet can make it rain.

What causes rain to fall?
Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
Do trees bring more rain?
They found that for more than 60 percent of the tropical land surface, air that has passed over extensive vegetation in the preceding few days produces at least twice as much rain as air that has passed over little vegetation.
What is rain made of?
Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth.
What exactly is rain?
Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud. Human life depends on rain.
Does rain have dirt in it?
Rain has to be dirty. Water droplets in clouds form when water vapour changes into liquid water around a condensation nucleus, such as a tiny particle of dust or soot, or a flake of salt.
