A few days ago, Sydney was enveloped in dust. An enormous dust storm swept over thousands of kilometers in Australia and made the sky appear red. Longtime drought conditions paired with severe winds to create the storm.
Health department officals declared the air quality to be 20 times the
"hazardous" level.
According to this article, an enormous dust storm stripped several millimetres of topsoil from hundreds of square kilometres of farms across New South Wales. The result will be a loss of soil productivity.
The Australian bureau of meteorology reported that this was the worst dust storm since the
1940s, with particle pollution up to 10 times worse than the previous
record.
The swath of dust is impressive in this NASA satellite photo.
