https://www.afinalwarning.com/494657.html (Natural News) Chinese researchers found an effective weather modification method to bring greater levels of rainfall. The method works by firing low-frequency sound waves at clouds to vibrate water droplets and increase the likelihood of them merging into larger droplets. In a paper published in the journal Science China Technological Sciences, the researchers reported that the method can increase the amount of rainfall by up to 17 percent. They noted that the technology still needs refinement but hopes it will help increase the amount of rainfall in drought-prone areas. But critics are concerned that the method is scientifically unfounded and generates noise pollution.
