Hiding under a gooseberry bush somewhere ? What about the rain that doesn't fall ? actually it is the water that fills the dams. Warragamba is nearly so full that it might flood West Sydney. Whatever happened to Mr Flannery's wonky "predictions" ?

Tim Flannery Did Not Say Australia’s Dams Would Never Fill Again

Denialists like Bolt claim that Flannery meant by this that our dams would never fill again at any time for any reason from the date Flannery was speaking. However, what Flannery was actually saying that climate trends at the time indicated a long-term outcome of normalized water shortage consistent with IPCC projections

Flannery’s comments were to the effect that Australia was at the time currently experiencing a 60% fall in run-off going into dams due to hotter soils and greater rainfall take-up by drought-stressed vegetation and that this would be indicative of what we could eventually expect as a consistent and normal outcome in the future.

He did not say that the dams would never fill again at any time from the date he was speaking, which is the thick-as-a-brick intentionally distorted view presented by Bolt and fellow travellers. Flannery was pointing to a long-term outcome of normalized water shortage based on current data and climate trends.

Flannery’s quote in context is:

We’re already seeing the initial impacts and they include a decline in the winter rainfall zone across southern Australia, which is clearly an impact of climate change, but also a decrease in run-off. Although we’re getting say a 20 per cent decrease in rainfall in some areas of Australia, that’s translating to a 60 per cent decrease in the run-off into the dams and rivers. That’s because the soil is warmer because of global warming and the plants are under more stress and therefore using more moisture. So even the rain that falls isn’t actually going to fill our dams and our river systems

Bolt knows, but pretends not to know, that Flannery was applying IPCC modelling and projections to (then) present circumstances in relation to reduced rainfall and that Flannery’s statement are in accordance with those. Bolt also knows that IPCC projections include intensified (i.e. more severe) but rarer flooding events, which of course would fill the dams.

so who's 'thick as a brick'? Cheesy

He said that. So the dams filled despite global warming drying out the soil and preventing run-off.

Actually the plants use less water because of increased CO2. That should translate to less stress.

But don't worry it is from an IPCC model, so it must be true.

"Rising CO2 Boosts Plant Water Use Efficiency

More CO2 Means Less Water Stress for Plants
Another major benefit of atmospheric CO2 enrichment is that plants exposed to elevated levels of atmospheric CO2 generally do not open their leaf stomatal pores - through which they take in carbon dioxide and give off water vapor - as wide as they do at lower CO2 concentrations. In addition, they tend to produce less of these pores per unit area of leaf surface at higher levels of atmospheric CO2. Both of these changes tend to reduce most plants' rates of water loss by transpiration; and the amount of carbon they gain per unit of water lost - or water-use efficiency - therefore typically rises, greatly increasing their ability to withstand drought. "

Or perhaps this -

" Plant growth can be stimulated by elevation of CO2; photosynthesis increases and economic yield is often enhanced. The application of more CO2 can increase plant water use efficiency and result in less water use."
