You just have to Google "Tim Flannery desalination" to find lots of quotes from the great man. He has commented on the weather matching the IPCC predictions [sic] and mentions that the ground is so warm that any rain that does fall will not fill the reservoirs.
Australia has spent billions of dollars on desalination plants that are not actually required. Some have been moth-balled to save a few million a year in running costs. Remember, desalination plants are heavy users of energy and so produce expensive water so both environmentalists and consumers can see the problem.
That understanding of climate has already caused more damage because the Australian government then tried to keep the dams as full as possible, but when the rain came they could not absorb it in their reservoirs and they had to let it out which caused more floods down stream.
Following bogus climate information has real costs but the believers seem happy to sweep it all under the carpet.
