For the third time this year, Sydney has been hit by major floods. Scientists blame intense rainfall on a combination of factors - but, on social media, unfounded allegations of "weather manipulation" have spread widely.
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.
Experts say no single factor can explain this extreme weather, pointing instead to warmer oceans and saturated soils as contributing factors.
But conspiracy theorists aren't buying it. On social media, they blame the extreme rainfall on "cloud seeding" and "weather manipulation".
There is no evidence to back up such theories, but this hasn't prevented falsehoods from reaching thousands of people online.
