A new report on the effects of climate change in Australia paints an alarming picture of life in the city of Sydney.
It warns that if residents do not cut water consumption by more than 50% over the next 20 years, the city will become unsustainable.
The Commonwealth Scientific and Industrial Research Organisation report also warns that temperatures could rise 5C above the predicted global average.
This would leave the city facing an almost permanent state of drought.
Heat-related deaths would soar from a current average of 176 a year to 1,300 [by 2070].
Sydney would come to resemble the harsh, dry and inhospitable conditions of remote inland towns.
