The worst dust storm in 70 years swept across eastern Australia this week, as winds picked up millions of tonnes of red dust from Australia's drought-ravaged interior and dumped it on the coast. This week meteorologists predicted that many more major dust storms would occur if climate change leads, as expected, to deeper droughts
