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. There is no evidence to prove cloud seeding affected the flood. Queensland Premier Annastacia Palaszczuk has expressed her concern over the impact of the floods as the state is inundated by rain. Conspiracy theorists claim the floods devastating Australia's east coast are a 'government weather warfare attack' triggered by 'chemtrails' James Bartolo, former Melbourne anti-lockdown leader . A look at aerial and ground-based cloud seeding techniques. Some of those he contacted were surprised or angry, Berko said. Now theyve finally become mainstream. You are also pursuing funding initiatives at this point too, for your research. So it has a huge possibility to improve its efficiency. 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. We dont have that technology, she said. Media reports estimated at least 22 . Cloud seeding was first trialled in Australia in 1947 when the CSIRO got up in a light plane and released crushed dry ice into promising-looking clouds. Recent research suggests that the decades-old approach can be effective, though questions remain about how much water it can wring from the sky. The information and techniques are out of date and their effectiveness is not well understood.. 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. >$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. Covered in this AustraliaOne Update -. Farm Heroes Saga, the #4 Game on iTunes. Recent social media posts claim that the 2022 floods in Australia were caused or exacerbated due to cloud seeding. Cloud seeding. The costs are split among state agencies in Colorado, Utah and Wyoming, where the . CLAIM: A rain-enhancing process known as cloud seeding caused historic flooding in Tasmania, Australia, in 2016 and along Australia's southeastern coast this year. 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. As the trough is expected to move slightly east, computer models show that by Friday there is a bit of a bullseye over Brisbane, a BoM forecaster says. That aircraft was capturing images of the flood damage at the time, according to the statement. I'm your host, Laurel Ruma. 7.4 Cloud seeding from a plane uses silver iodide burners, dry ice pellets or hygroscopic flares. Unattached supercooled water vapour molecules in the clouds condense around these particles. (Photo: Flooding in Loganlea, Queensland on Feb. 28, 2022. 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. Hotter atmospheric conditions and oceans are driving much heavier rainfalls, scientists say. Nanotechnology can engineer material and design the material with well controlled size, shapes, and properties. APS ASSESSMENT: False. Clouds form when water vapor in the atmosphere cools and condenses to form tiny water droplets or ice crystals in the sky. The claims circulating online led to more than 100 threats being sent to Handel Aviation, despite it explaining the purpose of the flights on the contact page of the company's website.

One patent is filed on the titanium dioxide, sodium chloride material for warm cloud seeding, and another patent is filed for porous graphite oxide, silica dioxide, nano compensated for cold cloud seeding. But conspiracy theorists aren't buying it. Mr Bartolo's followers claimed aircraft leaving 'chemtrails' in the sky across NSW is how the cloud seeding process is being administered. But experts say the flooding has been worsened by climate change and a La Nia weather phenomenon. Compared to the current flood, the factor is almost threefold. A dangerous and bizarre conspiracy theory is circulating that the devastating floods which have torn through Australia's east coast are part of a 'government weather warfare attack'. Like: 'we have the pilots' names, we know where you live, you're going to pay for this,' kind of stuff," Handel told AFP. 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. This data describing my new seeding materials property and their interactions in atmosphere. For the third time this year, Sydney has been hit by major floods. The technique has been around for decades. Property damage. 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. out 'cloud seeding' - a weather . AN AUSTRALIAN AVIATION company says it has received more than 100 threats following an online conspiracy theory that its pilots unleashed a flooding disaster by cloud seeding. Here are the tales of two unsuccessful Queensland rainmaking experiments -Brisbane, 1882 Advertisement, The Brisbane Courier, January 31, 1882In January . 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. 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'. Brisbane has two features that make it susceptible to flooding. Could you explain in more detail how cloud seeding works? On the other hand, cloud seeding practice is to release artificial seeding materials as nuclei to initiate the water vapor in the cloud to condense into droplets and promote the formation of large droplets until they grow big enough to fall as rain. CBS News reported on April 8 that many Australian pilots and aviation companies received threats regarding false claims on social media about cloud seeding. We call them UAEREP [United Arab Emirates Research Program for Rain Enhancement Science]. Cloud seeding is a real thing. Australia, March 30, 2022 in an image taken from video. 2. As the water spreads to northern New South Wales, how did the so-called rain bomb develop? 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. Laurel: Your research signifies a milestone toward achieving greater water security in the world. Scientists blame intense rainfall on a combination of factors - but, on social media, unfounded allegations of "weather manipulation" have spread widely. Oct 15 (Reuters) - Floods caused by torrential rain are hitting large swathes of southeast Australia, inundating hundreds of homes and forcing authorities to urge thousands of people to evacuate . In Australia, water can be a scarce commodity, with variousareas of the country suffering through prolonged droughts at times. Fast forward to 2022 as Las Vegas, Nevada and the UAE are dealing with severe flooding which happened after acknowledged cloud seeding operations. Pilots get "really violent" threats after online rumors wrongly pin devastating floods on cloud seeding. The higher you move up to the atmosphere, quickly moving into subzero and very cold. Pictured: Large parts of Lismore in NSW are completely underwater after record rainfall, Hundreds replied to the post with messages claiming 'the government' is using experimental technology to carry out 'cloud seeding'. They remain as vapors in the air and move higher and further. Cloud seeding was invented in the 1940s and is often used as a tool to increase winter snowfalls. Cloud seeding experiments began in Australia during 1947 after American scientists made the discovery in 1946. 'Could also be the start of the universal basic income scheme for the displaced victims of this tyranny? 1. Some social media users are spreading false theories about what has caused multiple floods in Australia in recent years. The tiny vapors rise into the atmosphere without condensation nuclei, which are small particles. The previous record was 600.4mm in 1974. Dr. Zou leads a groundbreaking research project using nanotechnology to develop cloud-seeding materials. The report did not find evidence to prove that the cloud seeding flight contributed to the flood. Cloud seeding is the process of artificially generating rain by implanting clouds with particles such as silver iodide crystals. Atmospheric water is one such alternative resource. Since silver iodide and not elemental silver is the cloud seeding material, the claims of negative environmental impact are disputed by peer-reviewed research as summarized . Information supplied by Weatherzone based on data provided by the Bureau of Meteorology (BOM), Copyright 2023 Weatherzone | v6.5.8 (b498), Note to media: You are welcome to republish text from the above news article as direct quotes from Weatherzone. These fall to the ground as snow or raindrops, depending on the surface temperatures. The amount of snow or rain tied to cloud seeding has varied, with up to 14% reported in experiments in Australia. However, Dr. Zou explains, The cloud-seeding materials used today have been around for many decades. On the other hand, I am also dedicated to the scale up of the production, reduce the cost, and the application of the materials. 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. There's no evidence to suggest it played a role in the 2022 floods in southeastern Australia, either. , first developed in the 1940s, involves spraying fine particles of silver iodide and dry ice into a cloud system. Resources: https: . Silver iodide is an ice-forming agent, which causes supercooled water droplets to freeze in the clouds. Cloud seeding can also, in some cases, cause the cloud to grow larger and last longer than it would have without the modification. Conversely, she said cloud seeding would not dramatically worsen clouds that are already forecast to produce severe weather. This material can initiate ice nucleation followed by rapid growth starting from a temperature of minus 80 degrees. Conspiracy theorists spread the false claims after weeks of torrential rains led to deadly east coast floods over the past two months, engulfing homes and sweeping cars from the roads. The process works by shooting microscopic particles of silver iodide into existing clouds using land based generators or aircraft. 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. 15 February 2014. Cloud seeding involves adding small particles into existing clouds to help them grow. You took this on as part of your research. Is that correct? There has been torrential rain for two days and there is much more to come. Under NSW legislation, Snowy Hydro can only cloud seed when precipitation is likely to fall as snow to elevations below 1,400 metres. Prof Stuart Khan, an expert on water management at the University of New South Wales, says Wivenhoe gained about 1,450 billion litres of water, which all came in under three days. "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. For one of the planes, only the nose and part of the propeller are visible, and the photograph appears to have been . What are conventional cloud seeding materials, and then how does nanotechnology come into play? 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. In the open environment, it's more challenging. Do not sell or share my personal information. Unfortunately, such material is unpredictable, where and how much available. We also assess the Snowy Schemes reservoir storage levels to ensure additional snowmelt from cloud seeding will not contribute to flooding downstream, Snowy Hydro said. Cloud seeding got its start in 1947, with General Electric scientists working under a military contract to find a way to de-ice planes in cold weather and create fog to obscure troop movements. Hundreds replied to his post with comments claiming 'the government' was using experimental technology to carry out 'cloud seeding' - a weather modification process that theoretically alters the microphysical state of clouds, causing rain. Conspiracy theorists claim the motive for 'elites' carrying out a 'weather attack', which have seen communities around Byron Bay and Lismore underwater is to move people into 'smart cities'. In just four days, the equivalent of eight months' worth of rain fell, paralysing certain areas of Australia's largest city. Hydro Tasmania (HT)s cloud seeding activities on 5 June had no impact on precipitation, with this conclusion having a solid scientific basis, stated the June 2017 independent parliamentary, Hydro Tasmania also denied that its flights were to blame and said in a, shows the operation had no measurable impact on rainfall on that day., Sarah Tessendorf, a project scientist at the Colorado-based. So they form super cool vapor and crystallize into ice particles. Why Is the Government Cloud Seeding in NSW's Over the Areas That Have Just Been Ravaged by Floods? 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.". Why are you interested in this type of research? 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. 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. As the rain falls, the Brisbane River hits moderate flood levels. more time. Iran has already accused Israel of stealing its water by using cloud-seeding that reduces rainfall over its territory. An atmospheric research expert told The Associated Press that cloud seeding would not change the dynamics of a cloud enough to cause massive flooding. An amusement ride is seen inundated by floodwaters in Sydney. A few decades later, the US military brought cloud-seeding to the battlefield. Everything from wind speed, air movement and updraft, or a current of rising air, can affect a storms strength, Tessendorf said. We know the oceans are getting warmer and that puts more moisture in the atmosphere, and a warmer atmosphere can hold more moisture.. The global water shortage has continuously intensified by rapid population growth and economic development around the world. Mar 27, 2022 Cloud Seeding, . NSW's Snowy Mountains region. The flight was collecting images for aerial maps provided to Australian mapping company NearMap, he said. 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. About this record. Brisbane wakes up to major flooding. The pilot's aviation company said it was conducting aerial surveys for a . Often, a compound like Silver Iodine (AgI) is used as the particulate matter, as it is naturally occurring in the world in low concentrations. 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. Although cloud seeding has been around since the 1940s, climate change and population growth are driving scientists to take a closer look at the technology, which could offer a viable cost-effective supplement to existing water supplies, particularly in arid and semi-arid regions, like the United Arab Emirates. The language they are using such as "rain bombs" is clear enough for me,' a commenter said. "Cloud seeding is a . Cloud seeding aims to protect flood-hit Jakarta. This cloud seeding area spans over the high elevation areas of the Snowy Mountains within the Snowy Hydro water catchment area, covering approximately 2110 square kilometres. That's it for this episode of Business Lab. Wivenhoe has never dealt with that volume of water but it was lucky it was down at 60% at the start. Often they require minus 25 degrees or even lower. FILE - Buildings are surrounded by flood waters in Londonderry on the outskirts of Sydney, Australia, Thursday, March 3, 2022. Water vapour gathers around the particles and eventually falls as precipitation. Australia's 2022 floods have seen Brisbane's Southbank hit by a 'rain bomb'. Tuesday, March 7 (First round) Game 1: (12) Virginia Tech vs. (13) Georgia Tech | 2 p.m. | ACC Network . Laurel: Certainly, a number of possible commercial ventures. Cloud seeding is an artificial weather modification technique that involves introducing cloud condensation nuclei into the atmosphere, which enhances a clouds ability to produce rain and snow. March 28, 2022. Could this all just be a . 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. Mass Floods and Australia's High-Speed Rail. The area of cooler air in the upper atmosphere drifts into the low pressure trough and starts to deliver record-breaking downpours over Brisbane and its surrounds. Centrelink jobseeker overhauled with new 'point-based system' . The claim is false. 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.. Four police officers knocked down the former bodybuilder's door when he refused to open it, claiming they didn't have authorisation to be on the property. 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." In the midst of an historic megadrought, states in the American West are embracing cloud seeding to increase snow and rainfall. Unlock more weather data and layers options. Dr. Zou: The cloud seeding materials used today have been around for many decades. This temperature is much higher than most other known ice nucleate material. On social media, they blame the extreme rainfall on "cloud seeding" and "weather manipulation". that happened throughout February and March in Queensland and New South Wales, leading to more than a dozen deaths. Dr. Zou: Yes. It is not yet known whether these findings also apply to wild conditions. It involves manipulating existing clouds to try and help them produce more rain or snow. Of these four experiments, the Snowy Mountains saw statistically significant increases in rainfall during the experiment. 'It is very obvious. There is no single cause for the intense rainfall Sydney has experienced in the last few days. 'If you also know this, comment on your awareness of unnatural weather below. As Brisbane starts a long and costly clean-up, hundreds of cars are stuck on the main M1 highway to the south. one wrote. Published: 00:57 EDT, 31 March 2022 | Updated: 00:57 EDT, 31 March 2022. Handel said he tasked his operations manager, Anthony Berko, with responding to each email and calling people who provided their phone numbers. 4m ago. 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. Trains are cancelled, bus services limited, the main Bruce Highway is closed at multiple locations and 51,000 people are without power. To help advance the science, in 2015 the UAE government launched a new initiative, the UAE Research Program for Rain Enhancement Science. You can find out more about Snowy Hydros cloud seeding operations here. Were not altering the updraft of the clouds. At least 3,600 homes are flooded in Gympie. The image below shows how silver iodide can be used to create snow on the leeside of a mountain range. China, which already artificially alters its weather over major cities, plans to be able to modify weather over half its territory by 2025, to the alarm of neighbours including India.
