Thanks to Romanoz for alerting us to this fascinating research – see his comment #5. I now have the 20MB download – Antarctic Climate Change and the Environment – dated November 2009.
Under 220.127.116.11 Atmospheric data derived from ice cores
The last para on page 43 starts – Ice core sea-salt as a potential proxy for mid-latitude winter rainfall variability. The full text on p 43 & 44 is saved here if you click on “Read the rest of this entry” at the end of the post.
Fig 2.8 shows salt content of ice varying from 1300AD and the text says – [ The work in progress indicates that southwest Western Australia experienced periods of higher mean winter rainfall, with high interdecadal variability during 1300 to 1600 AD, followed by lower mean but less variable winter rainfall from 1600 to 1900 AD, which is similar to the past 50 years (Goodwin, in prep.).]
The text ends by saying – [This long record would be of enormous economic benefit to all water users in Western Australia.]
Fig 2.7 shows that in the phase illustrated in panel b, the SW of WA is affected by higher readings of MSLP (mean sea-level pressure) – more finer weather.
So WA water authorities and politicians should take note – there is evidence that pre-1975 SW WA rainfall was not some constant high-rain regime. The post-1975 lower rain regime may be a perfectly normal phase of long term cycles and nothing to do with Greenhouse as they have claimed ad nauseum – Chapter and verse for a decade or more.

I see it has been operating for 18 months and “…SA Water admitted the plant is likely to be mothballed in 2015 after its warranty period expires.”
Opposition Leader, Steven Marshall, says the Government should not have doubled the plant’s capacity from 50 to 100 gigalitres. “The original cost estimate for the 50 gigalitre site or infrastructure was going to be $500 million. We now find out the Government’s spent $2.2 billion,” he said.
“That of course is not money that the Government has paid. That’s money that every single water consumer in South Australia is going to be paying from now on.”
Sounds like another episode in the string of Australian desalination disasters and White Elephants.
I was looking for information summarizing the Adelaide water supply. This metro area map shows a lot of reservoirs and pipelines from the Murray River. However I can not find figures showing how much scheme water is sourced from rainfall around Adelaide and how much is from the river.
This story broke here in fanatasy-land a day or so ago but the roots go back two and a half years to October 2010 and earlier.
I have just faxed the ACT Chief Minister an open letter with ideas on reforming ACTEW. Here is the essential text.
Dear Chief Minister,
Re this ~$234K understating of one of the top ACTEW salaries.
Let us be clear here – this issue has been running for at least two and a half years.
I understood that the original +$600K figure (which was excessive enough) – came from a Canberra Times FOI request in 2010; if not under FOI then at least a persistent request for information that took months to be answered. Now we know the 2010 answer from ACTEW was wildly wrong and has stood until now.
Here is the 2010 story saved on RiotACT from two and a half years ago.
Mark Sullivan worth half a mil per year? – 8 Oct 2010
Clearly ACTEW needs major surgery and the following points might be just a start.
 Obviously they could source a replacement for less than half of what they are paying the current CEO. Review all salary scales and re-align with utilities from similar sized cities.
 ACTEW needs to be divorced from AGL in all areas.
 ACTEW should be pruned back to being an agency tasked to deliver the cheapest electricity and water to Canberra – prune back the top heavy ACTEW board and top management structure – sever non-core functions.
 Shut down their Civic offices and relocate to cheaper premises at depots in Fyshwick.
 ACTEW needs telling by Govt to cease all their “community sponsoring”. To the extent that worthy “community organisations” need financial help – a Minister should handle that task and make decisions to pay out taxpayers money through a Dept in an open and transparent process.
 ACTEW has wasted hundreds of $millions on gold plating our water supply while in the thrall of doomster climate change dogmas. A big contributor to blowing out the ACT debt.
 By “gold plating” I mean the unnecessary Murrumbidgee to Googong Water Transfer which should be put on “care & maintenance” at least cost to taxpayers.
 Your predecessor Chief Minister and Labor Governments contributed to ACTEW cost and debt blow-out by delaying construction of the no-brainer enlarged Cotter Dam.
And I have not started on wasteful Green power schemes – electric car scheme.
The BBC is reporting – New Zealand North Island hit by worst drought in 30 years. Curious to see some rainfall graphs I turned to KNMI Climate Explorer but it was not easy getting updated data. The GHCN V2 data assembled by NCDC in the USA has many data gaps post 2004 and ends anyway in March 2011 – see picture below. The CRU data ends at 2009. I wonder why – it still rains here and there – did somebody stop paying their salaries ?
So I turned to a shorter term partly satellite based data set from GPCP to bring the graph up to date at Dec 2012. The GPCP might reflect rain over both land and ocean – but that is what we have.
Note the grid area chosen misses out Southland and much of Otago west of 170°East. New Zealand should have rain data from say the 1860′s – if anybody has up to date station data please let me know – or please pass on URL’s to any published New Zealand rain history graphs.
This is a common feature when researching climate data – to find that recent data are worse than old data.
Perfect from 1900 to 2004 – then gaps abound.
It will be more interesting when the plan sees the light of day. When the Coalition makes it into Govt they will find entrenched water bureaucrats wedded too much to “Wentworth Group” ideas that would naturally oppose the vast majority of projects in this report. There has grown in Australia an influential group of interests in favour of more expensive water.
We are certainly paying in our water bills for the last 25 years or so when Green Anti-Dam dogmas have had too much influence. Anti-Dam sentiment allied with arm-waving arguments exaggerating the 2002-2009 drought have contributed to several uneconomic seawater desalination plants being constructed. Melbourne, Sydney and Brisbane desal projects are costing us multi-tens of $Billions and stand as huge “white elephants”.
Some things the Coalition could do without building a single dam.
First review all environmental flow specifications with a view to cutting them back. How crazy that the Thomson Dam for example has 35% of inflows wasted to the sea. Should add that on 5 Feb 2012 I posted – Possible Kimberley region nation building dam projects
Never used plans going back half a century.
I thought this marvellous anti-development beatup too good not to share – “CSG water may pose risk to coast: experts”
May we ask – and before 2002 they did not know that groundwater can seep to the sea ?
“Politics plugs rainwater plan” says the headline.
Completely missing the glaring issue that no matter how many residents spend their hard-earned shekels on rainwater tanks – no matter how many residents pay Mr Cameron $4000 for a rainwater collection system hoping for a smaller water bill – no matter how much this reduces their water usage piped from the water utility ACTEW which = the Govt. ACTEW will recover its costs in providing piped scheme water through water bills and rates to property owners, whether you use ACTEW water or not. Govt debt due to our water scheme has blown out by over a $1Bn in two years. Due to Labor and GreenLabor Govt mismanagement – Canberra now has a Rolls Royce water supply system – which property owners and residents will be paying for for generations with constantly increasing ACTEW charges. Property owners who feel the urge to install Green-fashionable feel-good water tanks – should check carefully before parting with their money.
