Fears Over Fukushima Radiation Overblown: Lawrence Solomon

By

“The immense suffering that the Japanese are enduring in the aftermath of their earthquake and tsunami is now compounded by torment over radiation releases from the Fukushima nuclear plant.

“While the torment is understandable, based on the reported amounts of radiation released, it is uncalled for. The evidence from Japan’s populace — inadvertent guinea pigs in the largest radiation experiment ever, in the aftermath of the atomic bombings of Hiroshima and Nagasaki in 1945 — indicates that fears over radiation can be overblown.

“Those who survived the immediate atomic blasts but were near Ground Zero died at a high rate from excess exposure to radiation. The tens of thousands more distant from Ground Zero, and who received lower exposures to radiation, did not die in droves. To the contrary, and surprisingly, they outlived their counterparts in the general population who received no exposure to radiation from the blasts.

A Land of Drought or Flooding Rains

By

EASTER Sunday in 1915 the community of Murrabit in the Central Murray Valley gathered for a picnic at a farm called Riversdale.   It had been so dry that the Murray River had run dry. 

 A photograph was taken of the buggies in the dry river bed. 

Today, March 9, 2011, I visited Riversdale and took a photograph of the Murray in flood.  

The third photograph shows me looking across to the exact spot where the buggies were parked in 1915. Water now extends for another 5 miles beyond the far river bank into the red gum forests.

Here is a clever video about what is wrong with government’s latest planning scheme for the Murray Darling Basin.

Interestingly Topher has quoted extensively from my 2003 monograph ‘Myth and the Murray: Measuring the Real State of the River Environment’.

‘Carbon Price’ Won’t Reduce Emissions from Power Stations

By

THE Australian government has announced plans to introduce a carbon price scheme forcing industry to buy a permit for each tonne of carbon dioxide emitted from July 1, 2012.  A trading system, with the carbon permit price set on a market linked to other schemes overseas, could follow in three to five years.  But the scheme is unlikely to achieve a reduction in carbon emissions from coal fired power stations.  Tony explains:

The Carbon Price and Coal-Fired Power:  A Note from Tony

We are being told that the introduction of this ‘Carbon Price’ will drive down the emissions of the offending greenhouse gas, carbon dioxide.

When those politicians stand at the podium and tell you this, it indicates only that they have no idea whatsoever of how electrical power is generated.

When I try and explain that what they say is incorrect, that is somehow perceived as my taking a political standpoint by disagreeing with the politics of either the Labor Government who are introducing this, or The Australian Greens Party, who are in fact driving the Labor Government on this matter.

To effectively understand what effect a ‘price on carbon’ will have on coal fired power generation, you need to understand how a coal fired power plant produces its electrical power, and once you can visualise this, then it becomes patently obvious that just placing a price on those emissions will not lower those emissions by any amount whatsoever.

Snowy Hydro tops up floods with environmental flow

By

WHILE residents of Wagga Wagga scrambled to save their belongings from rising flood waters there was a rumour circulating that the crisis was exacerbated by bureaucratic incompetence, in particular that Snowy Hydro was releasing environmental flow water into the already flooded Murrumbidgee River. 

I was angry at even the concept. It was inconceivable. I phoned Snowy Hydro early on December 10 to set the record straight.

I was put through to their media spokesperson, Paul Johnson, who assured me that Snowy Hydro would do nothing to exacerbate the flood crisis and in particular that no water was being released from Lake Eucumbene. The lake has a capacity nine times Sydney harbour, he said. It was only about 25 percent full because most of the rain had been falling below the Lake.

When I fed that reply back into the email stream from which the rumour originated, Ron Pike, a retired rice farmer and tireless advocate for agriculture, asked, “Why then have water levels in Lake Eucumbene been falling despite significant inflows?”

Perhaps water was being sent to the Snowy River, I thought, but surely not to the Murrumbidgee?

I phoned Mr Johnson back, to put that question to him, but he won’t speak to me anymore.  I phoned him back several times during the remainder of last Friday. His assistants initially assured me that he would return my call, but by 4pm, could only confirm that he was in his office and had received my many phone messages.

Earlier in the day I had asked to speak with Mr Johnson’s boss, David Harris, but was told he was unavailable. It was at about 1pm that I phoned around all the Snowy Hydro offices asking the same questions and leaving the same questions with the pleasant women who answer the phones. I hoped that someone knowledgeable would phone me back and explain why water levels were falling in Lake Eucumbene if no water was being released.

Eventually someone did ring me back, a Mr James Muddle from NSW Office of Water.  I said it was very kind of him to phone me, but that I really wanted to speak with someone from Snowy Hydro. He insisted that perhaps he could help. So I asked him, “Is Snowy Hydro releasing water from Lake Eucumbene?” He replied he couldn’t answer that question, that it would be an operational issue for Snowy Hydro whether any water was being released or not.  So I asked Mr Muddle what he did – wondering if I could ask him a question that he might be able to answer.  Mr Muddle replied that the NSW Office of Water was concerned with water policy issues.

“Ahh,” I thought and asked, “Is Snowy Hydro releasing water from Lake Eucumbene because of commitments to the NSW Office of Water to return water as part of its environmental flow obligations?” 

Mr Muddle replied that we don’t normally talk about environment flows when there are floods. So I asked, “No environmental flow releases are being made, that might be topping up the current deluge?”

“You are putting words in my mouth,” he replied.

After more questions from me, all of which Mr Muddle was unable to provide straight answers to, he suggested I phone Tony Webber at the State Water Corporation. And I did. He was not in, but his assistant Jane Urquhart, said she might be able to help and so I repeated my questions.

But alas, Ms Urquhart was unable to answer my questions. She did, however, promise to try and find out and emailed me back with a message from her “water delivery manager” that the information I was after could be found in the operating licence between Snowy Hydro and the NSW Office of Water on the NSW Office of Water website.

Well I went there to have a look, but where to start? The licence has a package of agreements, licences and other regulations and the current licence as at May 1, 2010, is only 102 pages long.  I started to read, but it was not easy going and the more I read, the more I doubted that I would recognise the answer even if I stumbled across it, because the document makes so many references to part three of schedule three then part four of schedule four, and in case of shortfall, in case of excess, in case of base passing flow, in this water year versus next dependent on how much water might be in which of the sixteen major dams at any one time.

So I sent some more queries back into internet world and all was finally revealed. A most reliable source and someone who recently attended a meeting with David Harris, the boss of Snowy Hydro, explained that somewhere in the range of 4,000 to 5,000 megalitres of water per day will continue to flow from the Snowy Hydro System, regardless of downstream impacts, because of environmental flow obligations in the Snowy Hydro operating licence.

Yep! Blowering Dam may be out of control, the water belting out of Burrunjuck, the Central Murray likely to go under again as early as Wednesday, but because of a formal agreement between NSW Office of Water and Snowy Hydro, involving an obligation to South Australia, approximately 500,000 megalitres, equivalent to one Sydney Harbour of water, must be released as soon as possible as environmental flow.

In short, senior bureaucrats have signed off on an agreement, which they are now honouring, which requires environmental flow releases into the already swollen Murray and Murrumbidgee Rivers. Of course these men in suits don’t live in the Murray Darling Basin and they will continue to receive a salary, paid into their Sydney bank accounts, regardless of how many extra wheat fields flood and extra homes are destroyed.

Inconceivable, but true.
