# Climate change mitigation through weather modification: cloud seeding as a global case study. Climate change mitigation through weather modification global case study..png"). Rain Enhancement, also known as cloud seeding, offers a sustainable source of fresh water by enhancing rainfall from specific clouds under specific conditions. Weather modification, specifically Rain Enhancement and cloud seeding technologies, plays a crucial role in the broader context of climate change mitigation and building climate resilience. By enhancing our capacity to optimize rainfall and manage water resources more effectively, we take strides toward addressing climate change-induced water scarcity. This event, hosted by the UAE National Center of Meteorology (NCM), will feature a diverse array of speakers, including experts and researchers from global entities like the WMO's Weather Modification Expert Team, the US Weather Modification Association, the European Geosciences Union (EGU), as well as NCM and its UAE Research Program for Rain Enhancement Science (UAEREP).

Based on its findings, Stanford University ecologist Jerry Bradley said: "I think you can squeeze out a little more snow or rain in some places under some conditions, but that's quite different from a program claiming to reliably increase precipitation." Data similar to that of the NAS study was acquired in a separate study conducted by the Wyoming Weather Modification Pilot Project, but whereas the NAS study concluded that "it is difficult to show clearly that cloud seeding has a very large effect", the WWMPP study concluded that "seeding could augment the snowpack by a maximum of 3% over an entire season.". In 2016, Jeff Tilley, director of weather modification at the Desert Research Institute in Reno, claimed that new technology and research has produced reliable results that make cloud seeding a dependable and affordable water supply practice for many regions. **^** "Weather Modification Association (WMA) Position on the Environmental Impact of using Silver Iodide as a Cloud Seeding Agent" (PDF).

* Federal reporting requirements may not include all information necessary to adequately monitor cloud seeding. 23) *For example, NOAA could use its existing authority to work with other government entities, researchers, and operators to update required data for reporting, and make changes to improve standardization of annual reports.* | * Better quality and transparency of information would improve broad understanding of cloud seeding. 24) *For example, government entities, industry associations, scientific societies, researchers, and operators could promote awareness of the distinction between long-term climate or geoengineering applications and short-term cloud seeding to alter local precipitation.* | * Better understanding of definitions and differences can inform debate about potential risks and benefits of cloud seeding. This report discusses (1) the emerging and current technologies for cloud seeding (and weather modification generally), (2) the potential benefits of cloud seeding, (3) challenges surrounding the use and development of cloud seeding, and (4) policy options that may help address challenges or enhance benefits of cloud seeding.

Cloud seeding is a physical process/Fundamentals/Chemical_Change_vs._Physical_Change) whereby a seeding agent comprised of minute particles is released into an **EXISTING** cloud formation with Supercooled Liquid Water (SLW). A seeding agent, most commonly Silver Iodide (AgI), is then released into the existing storm cloud by an aircraft and/or by ground-based generators. The Seeded and Natural Orographic Wintertime clouds: the Idaho Experiment (SNOWIE) utilized a full outfitted weather research aircraft to fly directly into clouds and release silver iodide plumes to detect and measure the impacts of seeding. An aircraft flies either through or above an ACTIVE storm cloud releasing a seeding agent (Silver Iodide) into the cloud that has favorable conditions for ice crystal formulation. Cloud seeding is the process of inputting a solid particle (nucleus) into an EXISTING cloud formation, that liquid water can formulate ice around, and essentially deplete the cloud by turning its water content into ice.

Desperate for water, several Western states have expanded decades-old programs to increase precipitation through cloud seeding, a method of weather modification that entails releasing silver iodide particles or other aerosols into clouds to spur rain or snowfall. In the U.S. West, the need for water is so acute and cloud seeding so cheap that even a very slight increase in precipitation is worth it, says Friedrich. Cloud seeding operators submit annual reports to states estimating additional precipitation caused by their efforts, often claiming hundreds of thousands of additional acre-feet, but “it’s kind of crude,” says Eric Hjermstad, who runs Western Weather Consultants, a cloud seeding company that manages several seeding operations in Colorado. Cloud seeding costs money, but the cost is relatively low compared to the value of water, even if the reports overstate increased precipitation, proponents say. “Cloud seeding may be putting the clouds back to a more efficient state where they may have been prior to humans,” he says.
