Laurel: Could you describe that weather chamber that you used in your experiments? AP'S ASSESSMENT: False. Cloud seeding adds small, ice-like particles to clouds. Through the advancement in nanotechnology and nanoscience, nowadays we are working to design and engineer cloud-seeding materials with optimal properties to ensure water vapor condensation will occur effectively and maximize the rainfall achieved, explains Dr. Zou. March 8, 2022 . For frequently asked questions, please check our Knowledge Base. This salt vapor then will recondense as very small particles. Cloud seeding programs in the upper Colorado River Basin, for instance, cost around $1.5 million each year. That aircraft was capturing images of the flood damage at the time, according to the statement. In the midst of an historic megadrought, states in the American West are embracing cloud seeding to increase snow and rainfall. To better understand the icons, colours and weather terms used throughout Weatherzone, please check the legend and glossary. 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. About as much as eight months' worth of rain has come down in just four days, bringing parts of Australia's largest city to a standstill. A decades old idea, with todays innovation, might be the answer to help drought-stricken countries and to fight climate change. There is no evidence to prove cloud seeding affected the flood. The extra water produced from cloud seeding can sit in water storages for multiple years. One reason for the wetness is likely La Nia, which for the first time this century has returned for three consecutive years. They remain as vapors in the air and move higher and further. Australia's path towards Agenda 2030. Were not altering the updraft of the clouds. 2023 BBC. 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. Handel said he tasked his operations manager, Anthony Berko, with responding to each email and calling people who provided their phone numbers. An atmospheric research expert told The Associated Press that cloud seeding would not change the dynamics of a cloud enough to cause massive flooding' (https://bit.ly/3NwnqJq). Most commonly used to increase precipitation as a drought management technique, cloud . In Australia, water can be a scarce commodity, with variousareas of the country suffering through prolonged droughts at times. Could you explain in more detail how cloud seeding works? 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. Usually, silver iodide particles are used. But a probe by the Tasmanian government found that cloud seeding did not contribute to or worsen the heavy rains - a conclusion since backed by independent scientists and experts. Laurel: Dr. Zou, thank you so much for being with us here on the Business Lab. Cloud-seeding is a weather-modification practice used to artificially create or promote additional rain/snow from existing clouds. 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. The floods have once again turned deadly, with the body of a man swept away by floodwaters in Queensland found by police this morning, bringing the state's death toll to 19 since January. Prof Bofu Yu, of Griffith Universitys Australian Rivers Institute, says in 2011 rainfall was concentrated in the west and not as widespread as the current flooding. However, Dr. Zou explains, The cloud-seeding materials used today have been around for many decades. "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. Resources: https: . However, some research has raised doubts about its longterm effects on the environment. Cloud seeding is the process of artificially generating rain by implanting clouds with particles such as silver iodide crystals. And why has Queenslands capital flooded again just 11 years after the devastation of 2011? The technique has been around for decades. But conspiracy theorists aren't buying it. This is done by firing small particles (usually silver iodide) into clouds . We designed and fabricated a porous nanocomposite of 3D reduced graphite oxide and silica dioxide nanoparticles. Showers and #thunderstorms will develop across eastern and central #Vic and parts of northern #Tas on Wednesday, continuing across the region until the weekend extending into eastern #SA and western Vic as well.Latest forecasts: https://t.co/EGP9Qynjs3 pic.twitter.com/4dZwkN8TKM.

There are scenes of devastation in low-lying suburbs, along creeks, and in the river itself where pontoons break free and ferry terminals are littered with smashed boats and debris. A Facebook post with over 23K views asserts this claim with footage from a news broadcast about cloud seeding before a severe flood in Southern Tasmania. . Source: Snowy Hydro. Artist depiction of cloud seeding drones. Top Stories. Cloud seeding experiments began in Australia during 1947 after American scientists made the discovery in 1946. 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." Scientists blame intense rainfall on a . "Those numbers tell us that this is an inexpensive way to help add water to the system. As the water spreads to northern New South Wales, how did the so-called rain bomb develop? 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. These images are used to assess the damage caused by recent weather events.. It's very promising to know more about the effects of this seeding material. NearMap confirmed to AFP the photos taken by Handel Aviation were commissioned to map disaster-affected areas for insurers and emergency services. There is no evidence to back up such theories, but this hasn't prevented falsehoods from reaching thousands of people online. This is a black-and-white photograph of a cloud-seeding operation over the Pacific Ocean near Sydney. Of these four experiments, the Snowy Mountains saw statistically significant increases in rainfall during the experiment. Cloud seeding can use either ground based generators and / or aviation for operations. "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," one widely shared post reads. 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. It involves manipulating existing clouds to try and help them produce more rain or snow. 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. Atmospheric water is one such alternative resource. Water that seeps deep into the soil can influence groundwater levels for months. 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. 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. The pilot's aviation company said it was conducting aerial surveys for a . Ouse in the Derwent River catchment was one of the hardest hit areas in this week's floods. Snowy Hydro also has other criteria for cloud seeding which includes; In addition to these atmospheric conditions, Snowy Hydro also takes into account the amount of water already in the landscape. 'Moving people into so-called 'smart cities' is likely, I think, considering the World Economic Forum openly talks about these things. 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. Silver iodide is an ice-forming agent, which causes supercooled water droplets to freeze in the clouds. Unfortunately, such material is unpredictable, where and how much available. 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. CLAIM: A rain-enhancing process known as cloud seeding caused historic flooding in Tasmania, Australia, in 2016 and along Australias southeastern coast this year. 'The Gold Coast and surrounds is currently under a government weather warfare attack,' he told his army of devoted followers. As the rain falls, the Brisbane River hits moderate flood levels. The amount of snow or rain tied to cloud seeding has varied, with up to 14% reported in experiments in Australia. A really strong storm, she explained, will already have a very strong updraft and windflow characteristics that help create the cloud to begin with. 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."

Singapore should also build more drainage canals to effectively reduce the occurrence of . 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. >$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. Cloud seeding. Snowy Hydro's Cloud Seeding Program boasts that it has been able to increase rain or snow by 14 percent over the colder months. 15 February 2014. On the other hand, I am also dedicated to the scale up of the production, reduce the cost, and the application of the materials. Social media users are also sharing a separate example to baselessly claim that cloud seeding played a role in. To achieve this, we use the nanotechnology to deposit titanium dioxide nanoparticles as a shell layer and sodium chloride crystal core. 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. Hotter atmospheric conditions and oceans are driving much heavier rainfalls, scientists say. The flight was collecting images for aerial maps provided to Australian mapping company NearMap, he said. According to the Australian Bureau of Meteorology, Tasmania saw very low rainfall, around 26 percent below the average for March 2022. Many of the accounts seen by the BBC posting this type of content have also shared other conspiracy theories involving global warming, Covid vaccines, and the Moon landings. 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. In just four days, the equivalent of eight months' worth of rain fell, paralysing certain areas of Australia's largest city. 1. There are up to 15,000 homes flooded in the city, with 1,544 people in evacuation centres in the south-east. Wivenhoe has never dealt with that volume of water but it was lucky it was down at 60% at the start. Laurel: Your research focuses on the cloud seeding material itself, specifically the nanomaterials as you mentioned, which is a more effective tool in generating rain from existing clouds. That's it for this episode of Business Lab. Dr. Zou: As we know, the global water shortage has continuously intensified by rapid population growth and economic development around the world. What could be the reason behind mass flooding down the east coast of Australia?

There is devastation in northern NSW as Wilsons River rises two metres above previous flood records, inundating the town of Lismore. A subtropical climate naturally suited to big rain events and a city and suburbs built beside rivers and creeks in front of mountain ranges. Cloud seeding gives these clouds a lot more ice crystals (or cloud nuclei). But others were distressed, telling the experienced pilot they had lost everything during the floods and thought the company was responsible. Unattached supercooled water vapour molecules in the clouds condense around these particles. Thanks for listening. 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. A dangerous and bizarre conspiracy theory is circulating that the devastating floods which have torn through Australia's . The silver iodide causes water droplets in the clouds to form ice crystals that become heavier and fall faster, releasing precipitation. Design thinking was supposed to fix the world. TOTT News March 8, 2022. Pictured: Local residents wade through floodwater in Lismore, NSW.
