But conspiracy theorists aren't buying it. There's no evidence to suggest it played a role in the 2022 floods in southeastern Australia, either. Iran has already accused Israel of stealing its water by using cloud-seeding that reduces rainfall over its territory. Cloud is an effective and safe way to enhance rain and snowfalls above natural levels. 'I have known for years they have been using this technology!' 'I've been in Wagga Wagga for the last four days and the amount of chemtrails in the sky above the Riverina region is beyond comprehension,' the person commented. They say it's all part of a government plan to "weaponise" the weather against its own people - a popular conspiracy trope that has been around for years. 2022. Using this information is very good to compare the performance of different materials, and we did that extensively. A really strong storm, she explained, will already have a very strong updraft and windflow characteristics that help create the cloud to begin with. However, experts told AFP the floods were naturally occurring and cloud seeding cannot cause flooding. NOTE: Dry ice used for cloud-seeding = solid carbon dioxide = CO2. But Khan says the Brisbane flooding could easily have been much worse. Conversely, she said cloud seeding would not dramatically worsen clouds that are already forecast to produce severe weather. Clouds can be seeded from the ground using silver iodide generators. The flight lasted an hour and 34 minutes over the Upper Derwent catchment, targeting Lake Echo. Silver iodide helps rain drops and ice crystals grow larger and increases the amount of rain and snow that can fall from clouds. It involves manipulating existing clouds to try and help them produce more rain or snow. Immediately after the seeding is released, the electronic equipment, which are electronic optical cameras, will quickly take many, many photos to record the image while the seeding material's falling. According to Snowy Hydro, their Cloud Seeding Program increases precipitation by an average of 14 percent.
