The red dust storms that swept across eastern Australia were the worst in 70 years.
Dr John Leys, principal research scientist with the New South Wales department of climate change and water, told the Sydney Morning Herald that initial estimates showed the dust plume stretched 373 miles along the state’s coast from Sydney to the Queensland border, dumping up to 75,000 tonnes of dust an hour into the Tasman Sea. “It’s travelled about 1,500km to get to Sydney,” he said.
