A number of prominent scientists around the world said that Australia’s recent travails — prolonged drought, devastating fires and now dust storms, which blanketed Sydney last week — are linked to climate change, which is making an arid continent’s environment far more disaster prone. Some Australian researchers emphasized historical weather patterns. Conservationists, while calling for global action on climate change, also said that Australia needs to do more in its own backyard to protect land and water resources from agricultural, development and industrial interests.
What is the relationship of climate change to Australia’s problems? What is the lesson for the rest of the world?
