[AUS] Climate change could shift rainfall line

Rural communities have been mentioned as commenting that Rain seems to be passing them over, whilst snow falls freely and in heavy drops on the Ranges.

Perhaps attempts to make the National Water policy of Australia based on 'water recycling' of a rapidly diminishing WATER resources, accompanied by expressions of hope and faith in future rain fall, should be more solidly supporting processes (as example, desalination) that can produce water INFLOW to catchments.

As another example of 'blinkered realisations', it needs to be realise that in REALITY 'ground water' needs to fall somewhere as RAIN, and if the catchments of the Great Artesian Basin (holding in underground reserve 65 Million Billion litres) are noticed, the INFLOW on to the West indicates the N.T. wetlands influence, whilst the East is from the Great Dividing Range. So 'ground water' is INFACT only an expression of NATURAL CATCHMENTS that require RAIN, and the inflow of the GAB is only 300 Million litres per day.

As such 'groundwater' availability WILL be mediated by RAIN PATTERNING.

To example the issues being bullied away by a supposed 'greenhouse problem', consider another "Daily Telegraph' article that outlined a 'new' recycling plan for a section of NEW housing in the Sydney Basin. The scheme needs dual piping, as the recycled water will NOT be for drinking, so this excludes existing homes. The scheme (as mentioned) proposes that 27 BILLION litres will be treated per YEAR (eventually). Presently, with current population (growing still at around 1000 people per week however) the water SHORTFALL is ~10 BILLION litres per WEEK (*) drawn from catchment.

* See:- http://www.sca.nsw.gov.au/dams/bydate_index.html

Next, 'stage one' of the recycling plan will be produced by 2009. At the current average percentage decline however, catchments have the very STRONG likelihood to have ZERO % retention by 2009 also (*).

So, SOME OF the residence of Sydney will have been connected to a 'recycling system' just in time for ALL of the residence of Sydney to have NO WATER.

That is the problem with the 'blind faith' principle that has overrun so much of what is passed as an 'environmental management' concept (and perhaps training).

Years ago, it was realised that the 'river systems' of the plains regions of Australia had 'ghost courses' about the present river runs indicating that the drainage systems that these water courses represent had shifting sources and additions. This was then interpreted as indications that rainfall patterning was varying across the continent of Australia and on longer term oscillatory patterning's than the ~300 years 'white settlement' has been present. There was mention at the time of a 1500 and 1000 year cycle, with the possibility of 'river course shifts' progressing in one direction within the 1500 year oscillation, and reversing 'back to the start position' in the 1000 year oscillation. As I have been ill for over a decade, I realise also that this information is at least a decade in being known. At that time climate change was dealt with, and was being seen, as being in the manner of the natural progression that it is.

There are also more direct indications of the effect the building vast urban areas on the coast, in replacement of the usual photosynthetic mass coverage, is having on catchment, rain behavior and inland snow fall. Even now, the 'snow regions' of Australia seem to be getting good snow falls already.

In Sydney, the rain that has fallen is settling close to the coast, I also expect the Blue Mountains, part of the Great Dividing Range, to the west of the Sydney basin, to also see more snow this winter. This is as the sprawl of building within the Sydney Basin is able now to generate sufficient kinetic additions to the atmosphere above the Sydney Basin to suspend water vapor and as such it is continuing until precipitation is able to proceed. This will mean that only a heavy suspension of water will drop within the 'basin' (and thus into most of the catchments) whilst 'coastal showers' will continue. The majority of precipitation will be 'forced' by 'geographical features' and present more winter 'snow' over the mountains just to the west of the Sydney Basin.

Also there will be more snow inland. This is not so much (in Australia) due to 'sprawl' but to the natural rematerialing of the surface by drought. As I have mentioned, the 'Urban Jungle' is infact more the "Urban Desert' in as far as the presented surface 'kinetic energy induction' behavior is regarded.

Also there will be more snow falling 'inland'. This is not so much (in Australia) due to 'sprawl' but to the natural rematerialing of the surface by drought. Even now, the 'snow regions' of Australia seem to be getting good snow falls. Today I hear Falls Creek (Victoria) is getting very heavy snow, in early May. I also notice that the MONTHLY decline in the SCA water store is still ~2% with NIL rainfall over catchments in the past 7 days with hardly ever more than 5mm in the majority of weeks this year.

I was only mentioning this to an individual, also named Peter, within the SCA (Sydney Catchment Authority) within the past fortnight, whilst querying details within the information presented on their internet site. I have also mentioned this effect in 'near past' discussions with my local State and Federal Members offices.

This effect has been more noticeable every year for the past 3 or 4, perhaps longer but as I have been ill such things have not been 'noticed' by me for a time. Today I hear Falls Creek is getting very heavy snow, in early May. I also notice that the MONTHLY decline in the SCA water store is still ~2% with NIL rainfall over catchments in the past 7 days with hardly ever more than 5mm in the majority of weeks.

Rainfall patterning alterations, in Australia, you don't say?
