Australia's Prime Minister Kevin Rudd was recently quoted as blaming the state of the River Murray and its associated lakes Alexandrina and Albert on climate change.
I'm sorry, but this is arrant nonsense...rainfall in the river catchment area hasn't varied enough to cause the present situation. The root cause of the lack of water in the Murray is GREED. Irrigators are pumping out as much as they can suck while the water is there...meaning not a lot goes downstream. Where's this water going? A lot of it is used to unnecessarily irrigate vines resulting in a glut of cleanskins selling for less than the bottle (that they are contained in) costs. Remember too, that when Australia exports wine a lot of water goes overseas. Water that the driest continent needs to keep at home.
Add to that the complete idiocy of Mike Rann's South Australian Government who happily let 12 Gigalitres of rainwater flow out to sea during a recent bout of precipitation while complaining there isn't enough water in the Murray to supply Adelaide's needs. Twice as much water as Adelaide needs falls on the city every year, but instead of catching it and storing it, the government whines about the Murray and commissions a desalination plant.
