The colors depict the wetness percentile; that is, how the levels of groundwater compare to long-term records (1948-2012). Some of the natural sources include bushfires, volcanoes and dust storms, while artificial sources of condensation nuclei include industry emissions and cloud seeding operations. 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. , first developed in the 1940s, involves spraying fine particles of silver iodide and dry ice into a cloud system.

Between 1967 and 1972, during the Vietnam War, it spent roughly $3 million each year on weather modification . Laurel: This is very critical because the cloud seeding materials go very high up into the atmosphere where it is very cold, correct? 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. Everything from wind speed, air movement and updraft, or a current of rising air, can affect a storms strength, Tessendorf said. 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. Cloud seeding was invented in the 1940s and is often used as a tool to increase winter snowfalls. 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.
