The current drought in Eastern Australia has focused the attention of all Australians on water but effective policy responses are missing in action. Isn’t it time to call it a water emergency? Quentin Grafton and John Williams report.
“Droughts are getting hotter because the planet is warming,” says Gergis, who spent a decade studying accounts and records of the country’s weather. “It’s not just natural variability that we are dealing with any more.”
In her book she also cites the CSIRO and the bureau’s Climate Change in Australia, that projects average temperature increases of about 4 degrees compared with the 1986-2005 baseline for much of eastern Australia by 2090 if global carbon emissions continue unabated. For Victoria, Tasmania and south-western WA, the temperate rise will be closer to 3.5 degrees.
