The Long term Solution for Perth Australia is likely desalination

I wrote in the last few months about Perth, Australia where Global Warming could theoretically turn it into a Ghost town. So, the likely long term solution there would be desalination for years it doesn't rain enough to sustain life in that City in the west of Australia.

Here is something from Wikipedia on it:

Begin partial quote from:

Desalination - Wikipedia, the free encyclopedia


Desalination is particularly relevant in dry countries such as Australia, which traditionally have relied on collecting rainfall behind dams for water.
According to the International Desalination Association, in June 2015, 18,426 desalination plants operated worldwide, producing 86.8 million cubic meters per day, providing water for 300 million people.[5] This number increased from 78.4 million cubic meters in 2013,[4] a 57% increase in just 5 years. The single largest desalination project is Ras Al-Khair in Saudi Arabia, which produced 1,025,000 cubic meters per day in 2014,[4] although this plant is expected to be surpassed by a plant in California.[6] Israel produces a higher proportion of its water than any other country, totaling 40% of its water use.[7]
