There is a hysterical op-ed (subscription required) in the Financial Review today by Chas Keys – former deputy-general of the NSW State Emergency Service.
So Barnaby Joyce and Tony Abbott want to tackle the flood problem by building more dams. This is a simplistic, pre-1950s solution to a problem that needs a considered, multi-faceted approach.
Do Joyce and Abbott realise how many dams would be required to store even a modest proportion of the water in the floods? Do they realise how little mitigation would actually have been achieved even with several more big dams?
This is a huge strawman. I don’t think anyone is suggesting that all rain falling from the sky be captured in a dam. Rather that dams be employed to reduce flood damage. There is evidence (HT: Bolt) that this could occur.
