Making it rain: Why more and more countries are turning to cloud seeding

#Cloud Seeding #Weather Modification #Precipitation Enhancement #Water Security #Climate Crisis #Silver Iodide #Rainmaking #Atmospheric Water

📌 Key Takeaways

  • Over 50 countries worldwide are implementing cloud seeding programs to control precipitation
  • Cloud seeding can increase local precipitation by 5-15% but is limited in area and duration
  • Technological advances have renewed interest in cloud seeding by enabling real-time measurement of effectiveness
  • Cloud seeding costs between $1-10 per hectare-meter of water, making it cheaper than desalination

📖 Full Retelling

More than 50 countries across the globe, including the United States, China, France, Russia, India, and Saudi Arabia, are increasingly adopting cloud seeding programs as part of a push to control when and where it rains, driven by the need to boost water supplies amid the climate crisis and address various weather-related challenges. The World Meteorological Organization reports that these rain-making operations, which involve introducing tiny particles like silver iodide into clouds to enhance precipitation, are now active worldwide. For many nations, the embrace of cloud seeding stems from rising water demands, while others use it to disperse airport fog, tackle air pollution, reduce hail damage, or manipulate weather for major events like the 2008 Beijing Olympics. Despite an 80-year history, interest in cloud seeding declined in the 1970s and 1980s due to difficulties in accurately measuring its effectiveness. However, recent technological breakthroughs have renewed enthusiasm for the technology. Augustus Doricko, CEO of Rainmaker, a California-based cloud seeding company, notes that two factors are driving renewed interest: increasing climate volatility creating water scarcity, and improved measurement capabilities that can verify cloud seeding effects in real time. His company has grown rapidly from 19 employees at the start of 2025 to 120 today, reflecting the booming interest in this field. Despite its name, Rainmaker primarily focuses on snowmaking rather than rain production. While cloud seeding offers potential benefits as a relatively affordable water enhancement option—costing between $1 to $10 per hectare-meter of additional water compared to desalination—it is not without challenges and controversy. The technique depends on existing cloud conditions, faces attribution problems, and may raise geopolitical concerns about 'rain stealing.' Countries continue to invest heavily, with China reportedly spending $2 billion on its weather modification program between 2014 and 2021, and Saudi Arabia allocating $256 million in 2022 for its regional cloud seeding initiative. However, results remain mixed, with projects in India and Iran showing limited success due to unfavorable atmospheric conditions.

Cloud seeding

Weather modification that condenses clouds to cause rainfall

Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation, mitigate hail, or disperse fog. The usual objective is to increase rain or snow, either for its own sake or to prevent precipitation from occurring in days afterward. Cloud seeding is undertaken ...

Weather modification

Act of intentionally altering or manipulating the weather

Weather modification is the act of intentionally manipulating or altering the weather. The most common form of weather modification is cloud seeding, which increases rainfall or snowfall, usually for the purpose of increasing the local water supply. Weather modification can also have the goal of pr...

Deep Analysis

Why It Matters

Cloud seeding is gaining global traction as a tool to address water scarcity exacerbated by climate change. This matters because it represents a technological approach to managing water resources, but also raises environmental and geopolitical concerns that require careful regulation.

Context & Background

  • Cloud seeding uses particles like silver iodide to enhance precipitation from existing clouds
  • The technique has been used since the 1940s but interest declined due to measurement challenges
  • Countries like China, U.S., Saudi Arabia, and India have active programs
  • Recent technological advances allow better verification of results
  • Primary applications include water supply enhancement and pollution reduction

What Happens Next

More countries will likely adopt cloud seeding as water stress increases, driven by improved measurement technology. Research will continue to assess environmental impacts and address geopolitical tensions over water rights between neighboring regions.

Frequently Asked Questions

How does cloud seeding work?

Cloud seeding introduces tiny particles like silver iodide into clouds to improve their ability to produce rain or snow by providing nuclei for ice crystal formation.

Is cloud seeding effective?

Cloud seeding can increase local precipitation by 5% to 15% under the right conditions, but results are incremental rather than transformative.

What are the main concerns about cloud seeding?

Concerns include potential environmental impacts, geopolitical tensions over water rights, and legal issues regarding downwind effects on neighboring areas.

Which countries use cloud seeding?

China, United States, Saudi Arabia, Russia, India, France and others have active cloud seeding programs for various purposes including water supply and pollution control.

Countries across the globe are increasingly turning to a decades-old weather modification technique as part of a push to control when and where it rains. Alongside the U.S. and China, which boasts the world's largest weather modification program, France, Russia, India and Saudi Arabia are among a growing list of countries to have experimented with cloud seeding . For many, the embrace of rain-making operations stems from the need to boost water supplies as global demand continues to rise amid the climate crisis . Others have sought to use cloud seeding to disperse fog at airports, tackle air pollution, reduce hail damage or even to manipulate the weather for major events, such as the 2008 Summer Olympics in Beijing . Cloud seeding aims to improve a cloud's ability to produce rain or snow by introducing tiny particles, usually silver iodide . The process is limited both in area and duration and, over time, is estimated to increase local precipitation by 5% to 15%. The concept is not without controversy , however. Since first taking place in the 1940s, cloud seeding experiments have raised concern over potential environmental and ecological risks and stoked regional security tensions , with countries accusing each other of stealing rain . Augustus Doricko, CEO of Rainmaker, a California-based cloud seeding company, said there are two dynamics at play that seem to be rekindling people's interest in the technology — both in the U.S. and across the world. AFP | Getty Images "One is truly just circumstance, a lot of these countries and regions are suffering from more volatility in climate and precipitation patterns and their water supply, and so it's leading them through necessity to be more creative than they were in the past," Doricko told CNBC by telephone. "Two, and I think this is like the real meat and potatoes of why Rainmaker got started, it's because in the last few years there have been some fundamental breakthroughs in how to do measurements and attribution of ...
