Sydney’s huge Warragamba dam was completed in early 1960 when the population was about one million. We have had rapic[sic] population growth and now, with no new storage facilities being built, we suffer occasional water shortages.

These water shortages are not caused by the population quadrupling. No way. They are really caused by fossil fuel induced AGW causing drought. No politician in Australia would seriously propose building anything as radical as a new dam. Instead, we are building a huge sea water filtration which might provide 10% of Sydney’s fresh water needs - if required. The recent torrential rain has reduced the urgency of the plant but population is still growing and it might get dry again at some time in the future.

The filtration plant will be powered by electricity from our coal burning power plants.

You couldn’t make this stuff up if you tried.

No you couldn't.
