Most studies focus on hygroscopic materials with high water vapor adsorbing capabilities as potential cloud seeding materials, and they are only effective at above -zero temperatures. However, studies on cloud seeding at subzero temperature (cold cloud seeding) have not seen much progress, with Agl as the most commonly used cold cloud seeding materials for decades, which is often associated with controversial environmental risk.

Observing the behavior of such a teensy, so to speak, black hole, Ms. Baldassare and her colleagues hope, will help them understand where the monstrous black holes found in regular galaxies come from and how they grow so big. Some astronomers speculate that they are seeded from giant clouds of primordial gas, or the collapse of gargantuan stars that inhabited the dawn of time, and then grew by merging with other black holes as galaxies collided during the rough and tumble days of the early universe. The RGG 118 black hole is like finding a preteenager on the verge of all this. In the fullness of cosmic time, it could grow into a true monster. —DENNIS OVERBYE ...

1 month ago - He's sceptical about what was shot into the clouds, and questions how safe it was for both residents and their habitat. "It doesn't appear that there was any downstream monitoring to verify that this silver iodide didn't impact the environment," he says. Freeman adds, "Having a company come in to do this seeding isn't going to solve our water woes, and it feels like a distraction from solving the urgent issues related to water conservation." Concerns are mounting about the challenges surrounding water security. United Nations Secretary-General António Guterres said in July "our world is using freshwater faster than it can be replenished", which echoes reports noting how the past five years have led to the driest period for global rivers in more than three decades. Cloud-seeding technology may be a drop in the bucket, as it doesn't create rainstorms.

Published Sep. 8, 2026at6:00am · Can drones carrying a few teaspoons of salt solve the public relations crisis around AI data centers? Some are betting that the controversial, 80-year-old practice of cloud seeding can make it rain for data centers — literally. Across the country, the push to build massive data centers to power the AI boom has run into growing resistance from locals and governments, who say the facilities are noisy and consume huge amounts of power and fresh water. The outcry is especially loud in drought-prone California. The Southern California cloud-seeding startup Rainmaker is in talks with Big Tech companies to stimulate rain near data centers and bring fresh water back to the ground, CEO Augustus Doricko told The Standard.

However, despite its good ice nucleating ability, AgI requires much lower temperature (−25° C.) to exhibit good ice-nucleating ability, in addition, it is associated with controversial environmental risk. However, they only display an initial high ice nucleation counts and cannot further increase the numbers with the reduced temperature. In addition, such bacteria-based materials demand high cost for mass production and are not widely used for cloud seeding applications at present.

August 19, 2022 - Despite its potential, the risks associated with cloud seeding are high, and there is significant danger that cloud seeding may do more harm than good. “Human consequences.” As early as 1965, the National Science Foundation called for urgent social science research into the impacts of weather modification, stating, “If the developing techniques of weather and climate modification are to be used intelligently, the human consequences of deliberate or inadvertent intervention need to be anticipated before they are upon us.” But these issues continue to be under-explored. Compared to other forms of geoengineering that have received greater attention and generated more controversy—such as expanding research on solar geoengineering—policy discussions about the use (and misuse) of cloud seeding are lacking, even though it has been widely deployed.

February 9, 2023 - This being said, cloud seeding is a controversial technology that sceptics caution needs more development and study: What are the consequences of introducing chemicals into the clouds that we get our drinking and bathing water from? How does this affect the natural environment, the plants and animals living there, and the food that we get from it? What happens when wind pushes seeded clouds to an area where it wasn’t intended, not needed, and unauthorised? Can making it rain in one region deprive another of theirs? And if it does, this could cause international conflict (i.e. one nation accuses another of having ‘weaponised the weather’) by violating the Convention on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques (ENMOD) When seeding clouds with dry ice, which is essentially CO2, is that not simply adding more to the greenhouse ...

Even though cloud seeding has been used for more than half a century and has proven its usefulness in certain circumstances, this cloud manipulation technique is controversial. It fulfills humanity's age-old dream of controlling the weather and using it to its advantage in weather-sensitive activities such as agriculture or organizing outdoor events. But it is not without consequences on the environment and the geopolitical balance of the planet. On one hand, silver iodide used to trigger precipitation is among heavy metals and constitutes a toxic substance for aquatic species, which has led scientists to seek alternatives like calcium chloride. On the other hand, we still do not know how to measure and control all the consequences of this technique, including the risk of triggering excessive rainfall and floods or the risk of drying out a neighboring region.

July 1, 2017 - Meanwhile, there are several major difficulties in promoting the seeding technology (Wu et al. 2018), which include the high cost of operation, the risk of pollution (Fisher et al. 2018; Korneev et al.
