Climate change has parched Aussie farmers looking north

When the heavens open over the savanna flood plains and billabongs of northern Australia, it seems like it will rain forever. Great black storms march across the landscape, drenching the cattle ranches, national parks, and Aboriginal reserves which make up Australia's "Top End."

Thousands of miles to the south, however, in the most populous states of New South Wales and Victoria, the fields are parched, livestock are dying, and farmers face ruin as the worst drought in a century grinds on.
