Experts said that the floods in Australia were naturally occurring and cloud seeding cannot cause flooding. This show is available wherever you get your podcasts. Feast to Famine: Mass Floods and Australia's High-Speed Rail. She was awarded a grant by the UAE Research Program on rain enhancement science from 2016 to 2019. Dr. Zou: Yeah. The term 'rain bomb' was coined by Daily Mail Australia in 2017 to describe sudden and intense rainstorms, and has since been picked up by politicians and even the Bureau of Meteorology. So we can use them as input to develop one-dimensional and three-dimensional modeling of precipitation enhancement caused by cloud seeding, and the results prove quite successful. Some areas that flow into the river have had 300mm of rain in just six hours. 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. 'Surprisingly, they have talked about cloud seeding and weather manipulation on the mainstream media so it's coming from multiple sources now. Laurel: Then in the real world where we don't have this controlled chamber, it's not quite as easy necessarily to measure that kind of success. These small droplets and crystals usually form around even smaller particles of dust, salt and other aerosols floating in the atmosphere, which are called cloud condensation nuclei. Cloud seeding experiments began in Australia during 1947 after American scientists made the discovery in 1946. Despite the online claims, cloud seeding is not responsible for any of the east coast floods, said weather modification expert Simon Siems. Cloud seeding experiments began in Australia in 1947, shortly after the classic experiments of Schaefer (1946) in America showing that pellets of dry ice could rapidly glaciate a laboratory cloud. . Social media users are also sharing a separate example to baselessly claim that cloud seeding played a role in flooding that happened throughout February and March in Queensland and New South Wales, leading to more than a dozen deaths. There is no single cause for the intense rainfall Sydney has experienced in the last few days. There is no evidence to prove cloud seeding affected the flood. In Australia, a La Nia increases the likelihood of rain, cyclones, and cooler daytime temperatures. We call them UAEREP [United Arab Emirates Research Program for Rain Enhancement Science]. The technique has been around for decades. Is that correct? Reeling under the severe heatwaves and drought, some parts of Chongqing city in southern China welcomed the long-awaited rain as the southwestern . Play it now! Like: 'we have the pilots' names, we know where you live, you're going to pay for this,' kind of stuff," Handel told AFP. Copyright 2023 CBS Interactive Inc. All rights reserved. Dr. Zou: The conventional cloud seeding materials include mostly hydroscopic salt mixture, which can change from salt crystals into water droplets at the right condition. A Hydro Tasmania spokesperson told the AP that it has since stopped conducting cloud seeding. The pilot's aviation company said it was conducting aerial surveys for a . Given climate change is a background to all weather events, its hard to say that it does not play a role, he says.

In the U.S., studies have found a few percentage points of increase in precipitation. Prime inner-city areas including much of the South Bank precinct are underwater. But there is no evidence to suggest cloud seeding has anything to do with the current rainfall in Sydney. >$379 million (2022 USD) [1] Heavy flooding broke out in the Central Coast and Sydney areas of New South Wales, Australia, beginning in early July 2022. They vary in size. Figure 1: The area which is primarily targeted for increased precipitation from cloud seeding operations is shown in red (approximately 2110 km). in response calling the claims misinformation and denying that it conducts cloud seeding flights, stating that it only operates an aerial photography aircraft. Iran has already accused Israel of stealing its water by using cloud-seeding that reduces rainfall over its territory. Silver iodide helps rain drops and ice crystals grow larger and increases the amount of rain and snow that can fall from clouds. The information and techniques are out of date and their effectiveness is not well understood.. In their place, colder waters come up to the surface. Water vapour gathers around the particles and eventually falls as precipitation. Multiple posts on Facebook - as seen here, here and here - attempt to link Australia's floods with cloud seeding and possible government manipulation of the weather. A conspiracy theorist claims destructive rain and flooding in south-eastern Queensland and northern NSW are the result of man-made weather manipulation from "cloud seeding".. AP'S ASSESSMENT: False. Towards New Zealand, Domensino says, an area of high pressure known as a blocking high stops the system from moving away into the Tasman Sea. Of these four experiments, the Snowy Mountains saw statistically significant increases in rainfall during the experiment. China is developing a weather-modification system that aims to divert water vapour thousands of miles through the sky and bring rainfall to the country's driest regions. An independent investigation sought by Tasmania's parliament into the causes of the 2016 flooding found that cloud seeding, a process aimed at increasing precipitation, had no impact on the severe weather. (Photo: Flooding in Loganlea, Queensland on Feb. 28, 2022. A subtropical climate naturally suited to big rain events and a city and suburbs built beside rivers and creeks in front of mountain ranges. 'It is very obvious. Dr. Zou: The cloud chamber is a three-dimensional experimental environment. A high tide on Sunday evening pushes the river higher as the rising ocean water effectively holds back the freshwater. They remain as vapors in the air and move higher and further. THE FACTS: In recent months, Australias southeastern coast has experienced some of its, in more than a decade, leading some social media users to highlight a previous instance of flooding and spread false theories about what caused, Twitter users are sharing a clip from a 2016 news broadcast about flooding in Tasmania to claim it proves that. Source: Snowy Hydro. THE FACTS: There's no evidence to suggest that cloud seeding played a role in either flood, and an atmospheric research expert told the AP that cloud seeding would . History of cloud seeding in Australia 7.5 Americans made the discovery in 1946 that pellets of dry ice could induce precipitation from clouds. "They needed a shoulder to cry on and hear their story. [4] [5] The floods' damage was significant because rain fell on . At the moment, all possible solutions that could resolve the water shortage issue should be examined carefully. We know the oceans are getting warmer and that puts more moisture in the atmosphere, and a warmer atmosphere can hold more moisture.. Mr Bartolo's followers claimed aircraft leaving 'chemtrails' in the sky across NSW is how the cloud seeding process is being administered. 7.4 Cloud seeding from a plane uses silver iodide burners, dry ice pellets or hygroscopic flares. In just four days, the equivalent of eight months' worth of rain fell, paralysing certain areas of Australia's largest city. There is no evidence to prove cloud seeding affected the flood. Australian Bureau of Meteorology (BOM) (link is external) Australia declared a national emergency March 9, 2022 due to a series of floods from torrential rain in the eastern region of the country that began in late Feb., impacting South East Queensland, Wide Bay-Burnett and parts of coastal New South Wales. FILE - Buildings are surrounded by flood waters in Londonderry on the outskirts of Sydney, Australia, Thursday, March 3, 2022. A record-breaking and relentless deluge that lasted days and flooded towns and cities along Queenslands south-east coast, submerging thousands of homes and leaving at least nine people dead. A La Nia develops when strong winds blow the warm surface waters of the Pacific away from South America and towards Indonesia. Reuters quoted the Bureau of Meteorology, which said Sydney had received 1,227 mm (48 inches) of rain so far this year, more than its average annual rainfall of 1,213 mm adding that many coastal towns could see up to 180 mm (7 inches) of rainfall. Laurel: You've also developed another kind of technology, ice nucleating particles. Where did it go wrong. Cloud seeding. Cloud condensation nuclei can be introduced into the atmosphere naturally or artificially. Clouds can be seeded from the ground using silver iodide generators. Both those waterways flow freely into the Brisbane River below Wivenhoe, which is filling at an incredible rate. Flashes into the high RF appear on RADAR sometimes in the same geometric modulation patterns spoken about in HAARP research papers they appear coordinated with other stations, and not all stations in the same area produce the flash. Our topic today is cloud seeding to increase rainfall. 'Cloud seeding is being used to increase rainfall by corrupt governments to act on mother nature. The 'ice embryos' interact with the surrounding water droplets, and eventually grow to snowflakes. Today, that endeavor is making . Compared to the current flood, the factor is almost threefold. We will revisit our evidence and verdict and conduct additional research to verify new information. When doing so, please reference. Wivenhoe Dam Brisbanes main source of water and also a key piece of infrastructure to stop the city flooding starts rising rapidly from 58% capacity. Feast to Famine: Mass Floods and Australia's High-Speed Rail. Siems, a professor who leads a Monash University team studying clouds and precipitation, said the practice is not conducted in the Northern Rivers region and it cannot cause flooding. Sarah Tessendorf, a project scientist at the Colorado-based National Center for Atmospheric Research who leads the centers work on cloud seeding, told the AP that claims linking the process to flooding lack an understanding of how cloud seeding works. Conspiracy theorists claim the motive for'elites' carrying out a 'weather attack', which submerged communities around Byron Bay and Lismore, was to move people into 'smart cities'. That is about three Sydney Harbours worth of water. I'm your host, Laurel Ruma. Design thinking was supposed to fix the world. So, what is cloud seeding, how does it work and where is it used in Australia? In it, the newsreader reports on concerns by Tasmanian residents that the region's worst floods in 40 years could have been linked to cloud seeding. It's obvious when viewed on the radar.'. Using this information is very good to compare the performance of different materials, and we did that extensively. Laurel: That was Dr. Linda Zou, a professor of civil and environmental engineering at Khalifa University of Science and Technology, who I spoke with from Cambridge, Massachusetts, the home of MIT and MIT Technology Review, overlooking the Charles River. This means cloud seeding operations happen only during suitable cold weather systems, generally cold fronts between May and October. Another added: 'Absolutely nothing natural about the rainfall in the past 5 months. It will initiate from the thin water layer formed on the surface of the ice nuclease, and the ice will grow rapidly at the expense of the water vapor in the cloud. Read about our approach to external linking. CLAIM: A rain-enhancing process known as cloud seeding caused historic flooding in Tasmania, Australia, in 2016 and along Australias southeastern coast this year.
