Some of the natural sources include bushfires, volcanoes and dust storms, while artificial sources of condensation nuclei include industry emissions and cloud seeding operations. She added at $28-$34 per acre foot, cloud seeding is relatively cheap. Experts say no single factor can explain this extreme weather, pointing instead to warmer oceans and saturated soils as contributing factors. Nanotechnology can engineer material and design the material with well controlled size, shapes, and properties. Second, having the efficient seeding material for water droplet formation. Through a reverse image search, we found that 7News Melbourne posted the original broadcast on their Facebook page on June 10, 2016, with the caption: "Residents in southern Tasmania want to know why cloud seeding was conducted the day before severe flooding hit the region." The flight was collecting images for aerial maps provided to Australian mapping company NearMap, he said. Pictured: Local residents wade through floodwater in Lismore, NSW. Dr. Zou: Yes. ', Pictured: Military vehicles move through Lismore, NSW, with much of town now underwater, James Bartolo (pictured)says the weather event is 'not natural' and created by the government. Trials in Tasmania were also successful and since the 1960s, Hydro Tasmania has continued cloud seeding over the state. This shows us the risk is real to have two serious flood events in just 11 years is a pretty high frequency for a major city like Brisbane to have to deal with.. Cloud seeding, first developed in the 1940s, involves spraying fine particles of silver iodide and dry ice into a cloud system. Laurel Ruma: From MIT Technology Review, I'm Laurel Ruma, and this is Business Lab. Our topic today is cloud seeding to increase rainfall. The fact that the damage and loss of life were so great this time is due to the fact that many more people live in . On Tuesday morning evacuation orders are issued for South Ballina. Brisbane has two features that make it susceptible to flooding. , first developed in the 1940s, involves spraying fine particles of silver iodide and dry ice into a cloud system. Once such cloud encounters the ice nucleation particles, they rapidly form a large number of ice crystals and bypass the liquid water phase. Australia's path towards Agenda 2030. Hydro Tasmania, a hydroelectric corporation, published their analysis after the flood to say that a cloud seeding flight was undertaken on June 5, 2016, which had no measurable impact on rainfall. Conventional water resources such as rivers, lakes, and groundwater have become very limited, which is driving scientists and engineers to look for alternative water resources, says Dr. Linda Zou, a professor of civil and environmental engineering at Khalifa University of Science and Technology. A high tide on Sunday evening pushes the river higher as the rising ocean water effectively holds back the freshwater. The first three months of 2022 brought a year's worth of rain to Sydney. Some areas that flow into the river have had 300mm of rain in just six hours. The flight path of the Handel Aviation aircraft VH-JIL criss-crossing over flooded areas was also shared online by Australian fashion designer Alice McCall alongside claims it was dropping chemicals to "activate rain.". What are you working on now, and what are you thinking about next? Why doesn't Australia use the cloud seeding method? Companies covered in Cloud Seeding Market are RHS Consulting, Ltd North American Weather Consultants, Inc. As floods devastated Australia's east coast, social media posts accused a pilot of causing the disaster through cloud seeding, a weather modification technique that involves dropping a rain-inducing chemical into clouds. The Bureau of Meteorology warns that an area of low pressure over the south coast of Queensland is dragging in moisture from the Coral Sea to the north and then lifting it over the coastline. So they form super cool vapor and crystallize into ice particles. "The first stage of the project - an intensive data collection research component to improve the knowledge of cloud science in South-east Queensland, as well as a trial seeding component - commenced this week. Given climate change is a background to all weather events, its hard to say that it does not play a role, he says. A really strong storm, she explained, will already have a very strong updraft and windflow characteristics that help create the cloud to begin with. Ice nucleation is important. This is done by firing small particles (usually silver iodide) into clouds . It does not have the ability to suddenly produce all kinds of heavy rain and snow, Tessendorf said, adding, That process is just not really set up to take a cloud that may not be an effective precipitation producer and suddenly make it into the most efficient flood-producing cloud.. 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. 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. 2023 ACC TOURNAMENT SEEDING AS OF FEB. 26. The process works by shooting microscopic particles of silver iodide into existing clouds using land based generators or aircraft. In just four days, the equivalent of eight months' worth of rain fell, paralysing certain areas of Australia's largest city. Experimental cloud seeding technology does actually exist and has been used in places like China and the UAE. For general feedback and enquiries, please contact us through our Help Desk. My research work has been supported in their first cycle and received excellent worldwide exposure. Australia at present is in short supply of both, and even if more clouds begin to make an appearance in the Australian sky, chances are they will not be the right type. Unfortunately, such material is unpredictable, where and how much available. Seeding clouds as a way to change weather began its history as a serious science during WWII, originally as a way to interrupt severe storms or to produce rain and snow. reach out to us at [2] [3] Around 85,000 people were displaced by the flooding or requested to leave their homes by authorities. A pilot from Handel Aviation in Cessna 210N Centurion VH-JIL did a breakfast time cloud seeding run over Lismore South & Ballina today while sightseeing the massive flood below him, the post claimed without evidence, adding the names and contact information of employees at the company. 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. Cloud seeding is usually carried out by sprinkling particles from a plane. The comments below have not been moderated. The post's caption states, "There were no flood warnings for the area in Tasmania targeted by a cloud-seeding operation the day before floods devastated the town of Ouse." Electric vehicles have been available for decades. The flight lasted an hour and 34 minutes over the Upper Derwent catchment, targeting Lake Echo. (Audience submitted: David Bradley)"The extent to which cloud seeding has exaggerated the flood is still . These images are used to assess the damage caused by recent weather events.. Dr. Zou leads a groundbreaking research project using nanotechnology to develop cloud seeding materials. Learn more about fact-checking at AP. It involves manipulating existing clouds to try and help them produce more rain or snow. There's no evidence to suggest it played a role in the 2022 floods in southeastern Australia, either. 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. The river peaks overnight at the major flood level of 3.5m, falls slightly after the high tide, and goes higher to eventually peak on Monday at 3.85m below the 2011 peak of 4.46m. Mr Bartolo moved to the Gold Coast in November 2020 after he was charged with incitement for organising illegal protests during Melbourne's lockdown. Covered in this AustraliaOne Update -. Cloud seeding is a form of weather modification that mimics what naturally occurs in clouds but enhances the process by adding particles that can stimulate and accelerate the condensation process. Conspiracy theorists spread the false claims on social media after weeks of torrential rains led to deadly east coast floods over the past two months, engulfing homes and sweeping cars from the roads. Why have certain communities been targeted with geoengineered weather? What did you develop and how will it facilitate future research? At the moment, all possible solutions that could resolve the water shortage issue should be examined carefully. The flooding in October 2022 is the latest in a series of major floods to affect eastern Australia since unusually wet conditions began in early 2021. While scientists have blamed the. Cloud condensation nuclei can be introduced into the atmosphere naturally or artificially. There was a high degree of luck in terms of where we started from [with Wivenhoe Dam], he says, adding that the climate crisis will only raise the risk of future events. Nobody has ever seen this amount of rain in such a short period of time over our south-east catchment, says the Queensland premier, Annastacia Palaszczuk. Today, that endeavor is making . 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. In the 1950s, another scientist named Bernard Vonnegut proposed his cloud seeding idea in which he noted that clouds need other particles like bacteria or algae to produce precipitation. Cloud seeding: Making rain in desert. Domensino says while several features in the atmosphere combined to deliver the rain, climate change likely made the event worse. A rain-enhancing process known as cloud seeding caused historic flooding in Tasmania, Australia, in 2016 and along Australias southeastern coast this year. That hasn't stopped some TikTok users from denouncing "weather engineering". It was not written by MIT Technology Reviews editorial staff. The United Arab Emirates have been hit particularly hard by this season's sweltering heat, recording a 51.8C this June (that . Not since Charlemagne was crowned . Australia, March 30, 2022 in an image taken from video. THE FACTS: In recent months, Australias southeastern coast has experienced some of its worst flooding in more than a decade, leading some social media users to highlight a previous instance of flooding and spread false theories about what caused it and other floods over the years. The claim is false. After extensive testing, the CSIRO has determined that cloud seeding is unlikely to be effective in much of Australia. For more information about us and the show, please check out our website at technologyreview.com. Get browser notifications for breaking news, live events, and exclusive reporting. Could this all just be a . For cloud seeding to produce rain you need moisture to begin with. On March 30, 2022, BBC News reported that thousands of people had to evacuate their homes due to a severe flood on the east coast of Australia. Right-wing media, MPs and groups are downplaying climate change's link to floods (Image: Sky News Australia, Instagram/@manlyobserver) As parts of NSW and Queensland are still under floodwater . Others pointed to terms used in media coverage as proof the floods were part of an 'attack' and not natural. EPA. I used an eight cubic meter chamber with controlled humidity and temperature. that happened throughout February and March in Queensland and New South Wales, leading to more than a dozen deaths. After cloud seeding activities were carried out to bring precipitation, some parts of China's Chongqing welcomed long-awaited rains recently, but experts warned that the city and the region should prepare for possible flooding and landslides. Laurel: Certainly, a number of possible commercial ventures. Read about our approach to external linking. Laurel: Could you describe that weather chamber that you used in your experiments? Since the 1940s, scientists have studied ways to increase rainfall with the goal of increasing precipitation in arid and semi-arid climates. Dr. Zou: In the natural water cycle on the earth, the sun irradiates on the surface of our planet and the water on the surface is evaporated by the heat as the vapors. Conspiracy theorists . We know the oceans are getting warmer and that puts more moisture in the atmosphere, and a warmer atmosphere can hold more moisture.. The report did not find evidence to prove that the cloud seeding flight contributed to the flood. Brisbane suffered major flooding, along with the cities of Maryborough, Gympie, the Sunshine Coast, Caboolture, Toowoomba, Gatton, Ipswich, Logan City, the . The aerial images were commissioned after the flooding and were used to document the impact of the disaster on property and infrastructure, for government agencies, emergency services, insurance groups and others, according to the statement. Get in touch. "The idea that this is happening on a widespread scale, and that there is some motive to manipulate the weather is a complete myth," says Dr Ella Gilbert, a climate scientist at the British Antarctic Survey. The increased snowfall can also benefit ski resorts within the cloud seeding areas. This nanoengineered shell core structured material can be activated at much broader relative humidity conditions such as about 65%. Greta Thunberg joins activists' protest against a wind farm in Norway, Stronger hurricanes threaten homes even away from the coasts, Venice canals run dry as lingering weather system impacts tide cycles, Climate change is making winter weather warmer and "weirder". We designed and fabricated a porous nanocomposite of 3D reduced graphite oxide and silica dioxide nanoparticles. Mr Bartolo, a former bodybuilder who claims to be an army veteran, also promotes a range of other unhinged conspiracies including that vaccines and 5G are weapons, the world is flat, space is fake, the government is run by freemasons, and that the water supply is being poisoned. 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'. Then we can later analyze at what stage the droplets formed and at what number and size of the droplets. A flooded road is seen in Lismore, New South Wales, Australia, following heavy rains on March 2, 2022. Source: Snowy Hydro. In the 2016 clip from the Australian TV network 7News, a journalist says, Residents in southern Tasmania are demanding to know why cloud seeding was conducted over the Derwent River catchment the day before the worst floods in 40 years., One social media user shared the old clip Tuesday with the caption, Remember when this was a CONSPIRACY NOW - CLOUD SEEDING IS NOW OPENLY REPORTED - MAKING FLOODING WORSE - investigations are now being conducted as to WHY this was done!. The information and techniques are out of date and their effectiveness is not well understood.. What are conventional cloud seeding materials, and then how does nanotechnology come into play? The government can also provide flood insurance for the people. An independent investigation sought by Tasmanias 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. And yet, this myth seems to have found an audience on various social media platforms. Media reports estimated at least 22 . 4m ago. "Handel Aviation operates aerial photography aircraft only. As well as the rising river levels, the amount of rain falling locally causes flash floods all across the city and its outer suburbs as creeks swell, inundating areas that escaped the 2011 floods. Cloud seeding is a real thing. There has been torrential rain for two days and there is much more to come. The amount of snow or rain tied to cloud seeding has varied, with up to 14% reported in experiments in Australia. We were founded in 1899 at the Massachusetts Institute of Technology, and you can find us in print on the web and at events each year around the world. APS ASSESSMENT: False. Pictured: Local resident inspects floodwater in her street on March 31, 2022 in Lismore, NSW, Pictured: Debris from flood-damaged homes piles up in Lismore, NSW, Tuesday, March 29, 2022, Conspiracy theorist James Bartolo (pictured) claimsAustralia's east coast are part of a 'government weather warfare attack'. Cloud seeding is a real thing. This stored water can help ensure renewable energy generation and downstream water availability during future drier years, when inflows are lower. They've basically lost everything and then someone has then said here's your answer," Berko said. History of cloud seeding in Australia 7.5 Americans made the discovery in 1946 that pellets of dry ice could induce precipitation from clouds. A Hydro Tasmania spokesperson told the AP that it has since stopped conducting cloud seeding. At least 3,600 homes are flooded in Gympie. This is part of APs effort to address widely shared misinformation, including work with outside companies and organizations to add factual context to misleading content that is circulating online. As you know, cold clouds with sub-zero temperatures are also present in the atmosphere. Torrential rain hovers over the Brisbane region, feeding Wivenhoe Dam but also filling major rivers like the Bremer that winds through Ipswich and the Lockyer Creek. 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. This is a black-and-white photograph of a cloud-seeding operation over the Pacific Ocean near Sydney. Recent social media posts claim that the 2022 floods in Australia were caused or exacerbated due to cloud seeding. You can find out more about Snowy Hydros cloud seeding operations here. The natural occurring condensation nuclei are such as dust particles, volcano flash, or pollens. However, there is no evidence that cloud seeding was responsible for the flood. This will provide the people with a safety net to fall on, in the event of a flood. Social Credit? To be successful, scientists need the right air temperature, the right humidity, a surface that attracts water and keeps it, and then the correct size material to allow condensation to form on the particle. Dr. Zou leads a groundbreaking research project using nanotechnology to develop cloud-seeding materials. Additionally, silver iodide, a common agent . The pilot's aviation company said it was conducting aerial surveys for a . Australia One Party (A1) - Update March 3, 2022. The extra water produced from cloud seeding can sit in water storages for multiple years. Large areas of south-east Queensland are placed under a warning for intense rainfall and thunderstorms that will cause flooding. The colors depict the wetness percentile; that is, how the levels of groundwater compare to long-term records (1948-2012). We call them UAEREP [United Arab Emirates Research Program for Rain Enhancement Science]. Covid origin likely China lab incident - FBI chief. That's it for this episode of Business Lab. This means cloud seeding operations happen only during suitable cold weather systems, generally cold fronts between May and October. Dr. Zou: Yes. 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. Singapore should also build more drainage canals to effectively reduce the occurrence of . Unattached supercooled water vapour molecules in the clouds condense around these particles. They vary in size. Because the process is random and uncertain, the form and size of the particle cannot be controlled and most are probably too small to be effective cloud seeding materials. Despite the online claims, cloud seeding is not responsible for any of the east coast floods, said weather modification expert Simon Siems. Cloud seeding trials continued through the late 1950s and early 1960s by the CSIRO in the Snowy Mountains, in the New England district of NSW, the Warragamba catchment near Sydney and in the York Peninsula in SA. It's very promising to know more about the effects of this seeding material. Nearmap, which analyzes and distributes the companys photos, confirmed in a statement to the AP that the claims associating Handels recent flight with cloud seeding are false. Archives of Handel Aviations website dating back to 2008 show that cloud seeding services have never been mentioned or offered on its site and there is no evidence that the company has been involved with the process. And why has Queenslands capital flooded again just 11 years after the devastation of 2011? [4] [5] The floods' damage was significant because rain fell on . Water vapour gathers around the particles and eventually falls as precipitation. The conventional cloud seeding material can only be activated at a very high relative humidity in atmosphere in the cloud, such as greater than 75% relative humidity. Laurel: Dr. Zou, thank you so much for being with us here on the Business Lab. Dr. Zou's research interests include applying nanotechnology and membrane science to the development of low energy and high efficiency novel desalination and water purification solutions. Trains are cancelled, bus services limited, the main Bruce Highway is closed at multiple locations and 51,000 people are without power. Laurel: You've also developed another kind of technology, ice nucleating particles. The U.S. has a long history of cloud seeding, and gained a lot of attention in October of 1947 when it cloud seeded a hurricane. Cloud is an effective and safe way to enhance rain and snowfalls above natural levels. What are the challenges with then deploying the material out in the real world? Australian National Review is Australia's first real free and independent press, one with no editorial control by the elite, but a publication that can generate critical thinkers and critical debate and hold those . Dr. Zou: We want to move the materials, as I mentioned, from laboratory already and scale up, so it has a chance of reaching the market and to reach many different parts of the world as well, because there are so many countries worldwide that practice weather modification. This is done by firing small particles (usually silver iodide) into clouds . It was a wall of water. Silver iodide is an ice-forming agent, which causes supercooled water droplets to freeze in the clouds. Adkins said the crew involved in the seeding reported some effect . The condensation nuclei that give birth to clouds are extremely small, measuring around two micrometres, which is about 1/100th the size of a single cloud droplet. one wrote. In the midst of an historic megadrought, states in the American West are embracing cloud seeding to increase snow and rainfall. 15 February 2014. 7.4 Cloud seeding from a plane uses silver iodide burners, dry ice pellets or hygroscopic flares. AP'S ASSESSMENT: False. Design thinking was supposed to fix the world. Feast to Famine: Mass Floods and Australia's High-Speed Rail. There is no evidence to back up such theories, but this hasn't prevented falsehoods from reaching thousands of people online. The 2022 eastern Australia floods were one of the nation's worst recorded flood disasters with a series of floods that occurred from February to April in South East Queensland, the Wide Bay-Burnett and parts of coastal New South Wales. On the other hand, I am also dedicated to the scale up of the production, reduce the cost, and the application of the materials. BBC. 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. TOTT News March 8, 2022. Bartolo was handcuffed on his lounge room floor in a struggle seconds after the police broke inside. 2022 . To achieve this, we use the nanotechnology to deposit titanium dioxide nanoparticles as a shell layer and sodium chloride crystal core.
