There is much comment in the Australian media about water shortages and prominent in this whole “debate” is the Wentworth Group, who are held out to be water experts and Professor Peter Cullen, of Canberra I think, often seems to speak for the Wentworth Group. I have just noticed a recent news item, copied below, where Prof Cullen commences by restating some popular mantras.
“Much of Australia seems to be drying and we are now facing real water scarcity for many of our cities and for rural areas. This crisis in The Murray-Darling Basin has been brought on by the climate shift and the serious drought..”.
The black trendline on this BoM rainfall history 1900-2006 for the Murray Darling Basin (MDB) shows the 1940’s were dryer than now and there is NO evidence in these data of a climate shift. It is perfectly clear that current dryer conditions are normal cyclic events to be expected and that planning of urban water infrastructure has failed to keep pace with population and consumption trends.
I agree with many of the other points in the article and fully expect that Wentworth Group people will dominate the “experts” group to be appointed under the Federal Governments new plans.
“On February 22nd, the Australian Government’s Bureau of Meteorology issued a “Neutral” three-month outlook for the country’s Northern Territories, writing, “The Northern Territory outlook for total March to May rainfall shows no strong swings in the odds toward wetter or drier conditions.” A few days later, one of the world’s largest producing uranium mines shut down because of heavy rainfall and flooding, ..etc”
The BoM prediction/forecast, whatever, could not hold for a week. Readers here may have seen my critique of years of failed BoM rainfall Outlooks at: www.warwickhughes.com/drought/ which could do with updating.
Premier Peter Beattie and his Deputy Premier Anna Bligh are whining in concert that the Federal Government is not doing enough to assist drought-stricken Queenslanders.
Within the last ten years the Queensland Govt. stood by and let Cubbie Station trap river flows at the border with NSW up to a scale of 600 GL per year (MDBC), about equal to the annual water consumption in Sydney. Continue reading Queensland Govt., stunning hypocrisy over water→
Recent news items copied below record the discovery of a 140 million year old trapdoor spider species in the SW of Western Australia. If is fascinating to read carefully the words from the Department of Environment and Conservation and ponder how they reveal exactly how Dark Green policy is formed that will impinge irrationally on the States population.
Here is a species that has survived since before the dinosaurs and in just the last million years has coped with four global ice ages, involving repeated climate changes through times that were most certainly, hotter than now, colder than now, wetter than now and dryer than now. Not to mention tens of thousands of years subjected to indigenous forest burning customs, followed by over a century of european logging.

Finally got around to assembling a rain history for the Brisbane River catchments. More to say at the above link.
This is the graphic.
I have more to say at the above link.
So much still to be discovered.
The Govt. is constructing a ~$400Mill seawater desalination plant to produce 45GL PA.
In 2005 May to October (the runoff season) Perth dam catchments which total 3500 squ. kms had circa 958mm of rain. This equates to about 3353GL water falling free into catchments of which approx. 115GL flowed into dams, meaning that catchment efficiency (yield) was 3.4%. One of these villages, Becchi, was to be the birthplace of one of the most powerful men in our Church. www.slovak-republic.org/residence/eea/ levitra price They buy cheap levitra have natural beauty rather than salon generated looks.

Kamagra first has been helping men with their battle against tablets viagra erectile brokenness (ED) since 2004.
My graphic at the Perth Water Users web site shows that up until the mid 1990’s catchment efficiency was 5.5 to 6%. Let’s just assume for a minute that our Governments had been sensible and maintained catchment management work, keeping yields this year at say 5.7%. An increase of 2.3% (5.7-3.4) in this years yield would have put an extra 75+ GL (2.3% of 3353 GL) into our dams, which is 160% of the projected production from the Kwinana Desalination Plant (KDP), where costs have already blown out to over $387Million.
