What if I told you that humans have been doing this? control the weather For decades, or at least trying to? This is not science fiction, nor is it just a conspiracy theory. Cloud seeding is a real technology with a long and colorful history, and it's making headlines again as people speculate about its role in today's increasingly bizarre weather patterns.
First, what is cloud seeding? Cloud seeding is used to increase or suppress weather phenomena, especially precipitation. It is important to understand that this process, for better or worse, is human intervention in the weather. Moreover, this intervention can be carried out by plane or drone, but this is just one method of cloud seeding that has been developed in the history of this process.
There are some questions and uncertainties regarding the long-term effects and unpredictability of weather manipulation, not to mention the historical abuses in which this technology has already been used.
Scientifically speaking, cloud seeding introduces compounds or particles into a storm system that triggers rainfall. around earth.orgThe most commonly used compound is silver iodide (AgI), but others include sodium chloride (NaCl), calcium chloride (CaCl2), potassium iodide (KI), dry ice (solid CO2), and sulfur dioxide ( SO2), bismuth, etc. triiodide (BiI3), and propane (C3H8). Regardless of the compound, the released particles mimic the formation of ice crystals in clouds, allowing moisture to “stick” to these artificial compounds. The weight of these “nuclei” causes rain to fall from the cloud.
Silver iodide is the preferred chemical because its structure closely resembles that of natural ice crystals. Additionally, one gram of silver iodide can produce trillions of artificial ice crystals. This is an understandably popular compound, not only because it is structurally very similar to ice crystals, but also because it is very cost-effective.
Origin of cloudy weather
Vincent is credited with the formal discovery of cloud seeding techniques. Schaeffer and Bernard Vonnegut (yes, that's his brother) Kurt Vonnegut). They separately discovered two different methods around the same time. One is to use dry ice to change the heat of a cloud system, and the other is to use chemical manipulation of clouds to simulate the formation of ice crystals. But ultimately, cloud seeding is achieved both ways, attempting to manipulate ice crystals within clouds. General Electric discovered and developed these techniques. 1946. Both methods are used to this day and typically involve dry ice and silver iodide, respectively.
While many of the mainstream uses of cloud seeding are commonplace, the fact that this technology exists and has been used for decades is not. According to Earth.org, cloud seeding is used by governments to replenish water supplies in drought areas, combat extreme heat waves, suppress wildfires, and improve agricultural productivity. Meanwhile, ski resorts, insurance companies, and airports may employ the technology to increase snowfall, reduce hailstorms, and disperse fog, respectively.
Interestingly, not all applications of cloud seeding technology are so beneficial. For example, the U.S. military used cloud seeding techniques in the Vietnam War from 1967 to 1972 in a project known as Operation Popeye. According to new york times According to an article published in 1972, the project was intended to extend North Vietnam's monsoon season in order to influence military operations during the war, particularly along the Ho Chi Minh Trail. Increased rainfall during the monsoon season was expected to cause landslides and destroyed roads, disrupting North Vietnam's military supply chains and the movement of troops and weapons.
Additionally, the report showed that “many normally well-informed members of the Nixon administration were kept in the dark.” According to “highly qualified government officials,'' the operation was kept secret even within the government. [Kissinger] Information about it was limited to those who needed to know. ” This article suggests that Henry Kissinger played a direct role in this plan and its cover-up within the government.
According to Earth.org, cloud seeding for military use was stopped by a 1977 international treaty, but this historic example shows the technology's wide range of uses.
make it rain
In some experiments, new innovations appear to have streamlined the cloud seeding process. For example, it is reported “The United Arab Emirates has begun experimenting with the use of aerial drones for cloud seeding,” the article explains. It “zaps” clouds with laser beams, causing water droplets to coalesce and produce rain. ” The science behind this particular experiment is not very clear, but it shows that technology is improving and many countries are looking to refine this process. More broadly, we can conclude that this technology has been around for a long time, is explainable, and is in no way “magic.” But in true “Jurassic Park” fashion, there are, of course, ethical arguments that should supersede scientific investigation.
Cloud seeding can produce many positive effects. It could bring more water to arid regions such as the western United States and parts of China. They may also shape weather phenomena for less practical purposes. for example, China used this technology at the 2016 Beijing Olympics, claiming that it “cleaned the skies for the Beijing Olympics by making it rain earlier.” Ostensibly, it can stop hail from falling or reduce its size. It also has the potential to reduce harmful weather events such as hurricanes and monsoons.
However, cloud seeding can have negative consequences. First, the weather is obviously unpredictable, so while you can influence it, you cannot completely control it. According to the government formal Although he was familiar with Operation Popeye at the time, there were major errors in the experimental phase of the project. “We would fly around and look for specific cloud formations,” the official said. “And we made a lot of mistakes. Once, we dumped seven inches of rain in two hours on one of the special forces camps.”
Number 2, silver iodidecommon compounds used in the process of cloud seeding exhibit mild toxicity to humans over long periods of time. “Ingesting silver iodide can cause nausea, vomiting, and diarrhea. Prolonged exposure to silver iodide can cause argyria, a condition in which silver is deposited in tissues and turns them blue or gray. Most sources claim that the concentration of silver iodide in the water produced by this process is negligible. Even if we take these sources in good faith, we should be aware that our evidence likely reflects a small land area over a shorter period of time than is desired. In other words, the long-term effects of silver iodide in water in a large population like the United States are unknown.
It's amazing that this technology exists and seems to be somewhat effective. It is truly the result of human ingenuity. This technology has many potential benefits, and the hope is that companies with these capabilities will take advantage of them. We also need to learn more about the development of this technology in the future. There are some questions and uncertainties regarding the long-term effects and unpredictability of weather manipulation, not to mention the historical abuses in which this technology has already been used. These questions must be answered before this technology can be further utilized or expanded to larger scale operations. Let's hope that as more people become aware of this reality, there will be a stronger push for ethical discussions to develop alongside this amazing feat of science. If scientists have to “play God,” as some critics say, they should at least proceed very carefully.
