  • Ferguson pushes ALP toward nuclear


    This calls for rational debate: Mr Ferguson told parliament there needed to be a debate about whether Australia was "mature enough to select a site where we should store our low-level and intermediate-level nuclear waste".

    Party divided: The Labor frontbencher’s comments come only weeks after the deputy Labor leader Jenny Macklin, used an accident at the Lucas Height reactor in Sydney to campaign against nuclear reactors. "This accident is a stark reminder that things can go wrong with nuclear reactors," Ms Macklin said.

    Nuclear medicine needs fair hearing: But on 7 September, Mr Ferguson said in a debate about radioactive waste sites in the Northern Territory that the Australia, Nuclear Science and Technology Organisation, which runs Lucas Heights, played a vital role in nuclear medicine. "ANSTO is too often pilloried for their own political purposes by those who should know better," Mr Feguson said.

    No place for "fearmongering": "It is one thing to run an anti-nuclear campaign under-pinned by sound science logic and belief. It is quite another to stoop to ludicrous fearmongering about ANSTO and the Lucas Heights nuclear facility." He said the amendments dealing with ANSTO dealt with "the unavoidable consequences of nuclear medicine and nuclear technology in industry".

    Long running issue: The federal, state and territory governments have long debated the site of a low- to medium-level nuclear waste facility for radioactive material from medicine and research.

    "It’s time," says Ferguson: "It is time the games stopped at a state, territory and national level and at a political level," Mr Ferguson said.

  • US eyes Australia as carbon dump

    Aust project details:

    # Monash/Latrobe Valley: Paleogene-Eocene Latrobe group fluvial/deltaic sandstones
    # Gorgon: Jurassic Dupuy Fm. deep-water sandstones.

    Other potential test projects:

    North America:

    # Illinois/ORV: Cambrian Mt. Simon Sandstone.

    # GOM: Miocene Frio or Vicksburg Fms.; other Neogene shelf sands.

    # Rocky Mts: Mississippian Madison shelf carbonates or Pennsylvanian Tensleep/Weber eolian sandstones.

    # Alberta: Deep-water Triassic Viking Fm. Or Devonian/Mississippian reef complexes.

    Europe:

    # UK: DF1/Miller: Jurassic Miller Fm. deep-water sandstone.

    # Netherlands: K12B: Permian Rotliegende eolian sandstone.

    China and India:

    # China: Bohai: Eocene-Miocene Shahejie – Guantao fluvial-lacustrine sandstones.

    # China: Sichuan: Triassic Jialingjiang Fm., shelf carbonates.

    # India: Ganga: Eocene-Miocene Murree – Siwalik Fms. fluvial sandstones

    Huge return on investment claimed: The study says the value of information derived from large scale injection studies relative to their cost would be "enormous".

    US capacity questions would be largely answered: For the three projects suggested above in the US, the price tag would range between $300 -700 million over eight years. Five large tests could be planned and executed for less than $1 billion, and address the chief concerns for roughly 70 per cent of potential US capacity.

    Basis for regulatory decision making: The study continues: "Information from these projects would validate the commercial scalability of geological carbon storage and provide a basis for regulatory, legal, and financial decisions needed to ensure safe, reliable, economic sequestration."

    Aid for developing nations? It adds that on a global basis, the case for OECD countries to help developing nations test their most important storage sites is strong, though mechanisms remain unresolved and are likely to vary case to case.

  • GM farmers dying in India

    “A vice president pulled me aside,” recalled Kirk. “He told me something like, ‘Wait a second. What Robert Shapiro says is one thing. But what we do is something else. We are here to make money. He is the front man who tells a story. We don’t even understand what he is saying.’”

    Kirk felt let down. “I went in there with the idea of helping and healing and came out with ‘Oh, I guess it is just another profit-oriented company.’” He returned to California, still holding out hopes that the new technology could make a difference.

    Possible Toxins in GM Plants

    Kirk was developing the market in the West for two types of GM cotton. Bt cotton was engineered with a gene from a soil bacterium, Bacillus thuringiensis. Organic farmers use the natural form of the bacterium as an insecticide, spraying it occasionally during times of high pest infestation. Monsanto engineers, however, isolated and then altered the gene that produces the Bt-toxin, and inserted it into the DNA of the cotton plant. Now every cell of their Bt cotton produces a toxic protein. The other variety was Roundup Ready® cotton. It contains another bacterial gene that enables the plant to survive an otherwise toxic dose of Monsanto’s Roundup® herbicide. Since the patent on Roundup’s main active ingredient, glyphosate, was due to expire in 2000, the company was planning to sell Roundup Ready seeds that were bundled with their Roundup herbicide, effectively extending their brand’s dominance in the herbicide market.

    In the summer of 1997, Kirk spoke with a Monsanto scientist who was doing some tests on Roundup Ready cotton. Using a “Western blot” analysis, the scientist was able to identify different proteins by their molecular weight. He told Kirk that the GM cotton not only contained the intended protein produced by the Roundup Ready gene, but also extra proteins that were not normally produced in the plant. These unknown proteins had been created during the gene insertion process.

    Gene insertion was done using a gene gun (particle bombardment). Kirk, who has an undergraduate degree in biochemistry, understood this to be “a kind of barbaric and messy method of genetic engineering, where you use a gun-like apparatus to bombard the plant tissue with genes that are wrapped around tiny gold particles.” He knew that particle bombardment can cause unpredictable changes and mutations in the DNA, which might result in new types of proteins.

    The scientist dismissed these newly created proteins in the cotton plant as unimportant background noise, but Kirk wasn’t convinced. Proteins can have allergenic or toxic properties, but no one at Monsanto had done a safety assessment on them. “I was afraid at that time that some of these proteins may be toxic.” He was particularly concerned that the rogue proteins “might possibly lead to mad cow or some other prion-type diseases.”

    Kirk had just been studying mad cow disease (bovine spongiform encephalopathy) and its human counterpart, Creutzfeldt-Jakob disease (CJD). These fatal diseases had been tracked to a class of proteins called prions. Short for “proteinaceous infectious particles,” prions are improperly folded proteins, which cause other healthy proteins to also become misfolded. Over time, they cause holes in the brain, severe dysfunction and death. Prions survive cooking and are believed to be transmittable to humans who eat meat from infected “mad” cows. The disease may incubate undetected for about 2 to 8 years in cows and up to 30 years in humans.

    When Kirk tried to share his concerns with the scientist, he realized, “He had no idea what I was talking about; he had not even heard of prions. And this was at a time when Europe had a great concern about mad cow disease and it was just before the noble prize was won by Stanley Prusiner for his discovery of prion proteins.” Kirk said “These Monsanto scientists are very knowledge about traditional products, like chemicals, herbicides and pesticides, but they don’t understand the possible harmful outcomes of genetic engineering, such as pathophysiology or prion proteins. So I am explaining to him about the potential untoward effects of these foreign proteins, but he just did not understand.”

    Endangering the Food Supply

    At this time, Roundup Ready cotton varieties were just being introduced into other regions but were still being field-tested in California. California varieties had not yet been commercialized. But Kirk came to find out that Monsanto was feeding the cotton plants used in its test plots to cattle.

    “I had great issue with this,” he said. “I had worked for Abbot Laboratories doing research, doing test plots using Bt sprays from bacteria. We would never take a test plot and put into the food supply, even with somewhat benign chemistries. We would always destroy the test plot material and not let anything into the food supply. Now we entered into a new era of genetic engineering. The standard was not the same as with pesticides. It was much lower, even though it probably should have been much higher.”

    Kirk complained to the Ph.D. in charge of the test plot about feeding the experimental plants to cows. He explained that unknown proteins, including prions, might even effect humans who consume the cow’s milk and meat. The scientist replied, “Well that’s what we’re doing everywhere else and that’s what we’re doing here.” He refused to destroy the plants.

    Kirk got a bit frantic. He started talking to others in the company. “I approached pretty much everyone on my team in Monsanto.” He was unable to get anyone interested. In fact, he said, “Once they understood my perspective, I was somewhat ostracized. It seemed as if once I started questioning things, people wanted to keep their distance from me. I lost the cooperation with other team members. Anything that interfered with advancing the commercialization of this technology was going to be pushed aside.”

    He then approached California Agriculture Commissioners. “These local Ag commissioners are traditionally responsible for test plots and to make sure test plot designs protect people and the environment.” But Kirk got nowhere. “Once again, even at the Ag commissioner level, they were dealing with a new technology that was beyond their comprehension. They did not really grasp what untoward effects might be created by the genetic engineering process itself.”

    Kirk continued to try to blow the whistle on what he thought could be devastating to the health of consumers. “I spoke to many Ag commissioners. I spoke to people at the University of California. I found no one who would even get it, or even get the connection that proteins might be pathogenic, or that there might be untoward effects associated with these foreign proteins that we knew we were producing. They didn’t even want to talk about it really. You’d kind of see a blank stare when speaking to them on this level. That led me to say I am not going to be part of this company anymore. I’m not going to be part of this disaster, from a moral perspective.”

    Kirk gave his two-week notice. In early January 1998, he finished his last day of work in the morning and in the afternoon started his first day at chiropractic college. He was still determined to make a positive difference for the world, but with a radically changed approach.

    While in school, he continued to research prion disease and its possible connection with GM crops. What he read then and what is known now about prions has not alleviated his concerns. He says, “The protein that manifests as mad cow disease takes about five years. With humans, however, that time line is anywhere from 10-30 years. We were talking about 1997 and today is 2006. We still don’t know if there is anything going to happen to us from our being used as test subjects.”

    Update

    It turns out that the damage done to DNA due to the process of creating a genetically modified organism is far more extensive than previously thought.[1] GM crops routinely create unintended proteins, alter existing protein levels or even change the components and shape of the protein that is created by the inserted gene. Kirk’s concerns about a GM crop producing a harmful misfolded protein remain well-founded, and have been echoed by scientists as one of the many possible dangers that are not being evaluated by the biotech industry’s superficial safety assessments.

    GM cotton has provided ample reports of unpredicted side-effects. In April 2006, more than 70 Indian shepherds reported that 25% of their herds died within 5-7 days of continuous grazing on Bt cotton plants.[2] Hundreds of Indian agricultural laborers reported allergic reactions from Bt cotton. Some cotton harvesters have been hospitalized and many laborers in cotton gin factories take antihistamines each day before work.[3]

    The cotton’s agronomic performance is also erratic. When Monsanto’s GM cotton varieties were first introduced in the US, tens of thousands of acres suffered deformed roots and other unexpected problems. Monsanto paid out millions in settlements.[4] When Bt cotton was tested in Indonesia, widespread pest infestation and drought damage forced withdrawal of the crop, despite the fact that Monsanto had been bribing at least 140 individuals for years, trying to gain approval.[5] In India, inconsistent performance has resulted in more than $80 million dollars in losses in each of two states.[6] Thousands of indebted Bt cotton farmers have committed suicide. In Vidarbha, in north east Maharashtra, from June through August 2006, farmers committed suicide at a rate of about one every eight hours.[7] (The list of adverse reactions reported from other GM crops, in lab animals, livestock and humans, is considerably longer.)

    Kirk’s concern about GM crop test plots also continues to remain valid. The industry has been consistently inept at controlling the spread of unapproved varieties. On August 18, 2006, for example, the USDA announced that unapproved GM long grain rice, which was last field tested by Bayer CropScience in 2001, had contaminated the US rice crop[8] (probably for the past 5 years). Japan responded by suspending long grain rice imports and the EU will now only accept shipments that are tested and certified GM-free. Similarly, in March 2005, the US government admitted that an unapproved corn variety had escaped from Syngenta’s field trials four years earlier and had contaminated US corn.[9] By year’s end, Japan had rejected at least 14 shipments containing the illegal corn. Other field trialed crops have been mixed with commercial varieties, consumed by farmers, stolen, even given away by government agencies and universities who had accidentally mixed seed varieties.

    Some contamination from field trials may last for centuries. That may be the fate of a variety of unapproved Roundup Ready grass which, according to reports made public in August 2006, had escaped into the wild from an Oregon test plot years earlier. Pollen had crossed with other varieties and wind had dispersed seeds. Scientists believe that the variety will cross pollinate with other grass varieties and may contaminate the commercial grass seed supply­70 percent of which is grown in Oregon.

    Even GM crops with known poisons are being grown outdoors without adequate safeguards for health and the environment. A corn engineered to produce pharmaceutical medicines, for example, contaminated corn and soybean fields in Iowa and Nebraska in 2002.[10] On August 10, 2006, a federal judge ruled that the drug-producing GM crops grown in Hawaii violated both the Endangered Species Act and the National Environmental Policy Act.[11]

    A December 29, 2005 report by the USDA office of Inspector General, blasted the agriculture department for its abysmal oversight of GM field trials, particularly for the high risk drug producing crops.[12] And a January 2004 report by the National Research Council also called upon the government to strengthen its oversight, but acknowledged that there is no way to guarantee that field trialed crops will not pollute the environment.[13]

    With the US government failing to prevent GM contamination, and with state governments and agriculture commissioners unwilling to challenge the dictates of the biotech industry, some California counties decided to enact regulations of their own. California’s diverse agriculture is particularly vulnerable and thousands of field trials on not-yet-approved GM crops have already taken place there. If contamination were discovered, it could easily devastate an industry. Four counties have enacted moratoria or bans on the planting of GM crops, including both approved and unapproved varieties. This follows the actions of more than 4500 jurisdictions in Europe and dozens of nations, states and regions on all continents, which have sought to restrict planting of GM crops to protect their health, environment and agriculture.

    Ironically, California’s assembly, which has done nothing to protect the state from possible losses due to GM crop contamination, passed a bill on August 24, 2006 that prohibits other counties and cities from creating GM free zones. The senate is expected to vote on the issue by the end of their session on August 31st (see http://www.calgefree.org/preemption.shtml ). It is yet another example of how the biotech industry has been able to push their agenda onto US consumers, without regard to health and environmental safeguards. No doubt that their lobbyists, anxious to have this bill pass, told legislators that GM crops are needed to stop poverty and feed a hungry world.

    [Update 9/1/06:  The California Senate session ended without senators voting on the bill to prevent local jurisdictions from creating GM-Free zones. For the time being at least, California counties and cities may still enact GM-Free zones. Click here  to read the full press release.]]

  • U.S. Losing Control in Iraq

    "We are talking about nearly a third of the area of Iraq," Ahmed Salman, a historian from Fallujah told IPS. "Al-Anbar borders Jordan, Syria and Saudi Arabia, and the resistance there will never stop as long as there are American soldiers on the ground."

    Salman said the U.S. military is working against itself. "Their actions ruin their goal because they use these huge, violent military operations which kill so many civilians, and make it impossible to calm down the people of al-Anbar."

    The resistance seems in control of the province now. "No government official can do anything without contacting the resistance first," government official in Ramadi Abu Ghalib told IPS.

    "Even the governor used to take their approval for everything. When he stopped doing so, they issued a death sentence against him, and now he cannot move without American protection."

    Recent weeks have brought countless attacks on U.S. troops in Haditha, Ramadi, Fallujah and on the Baghdad-Amman highway. Several armoured vehicles have been destroyed, and dozens of U.S. soldiers killed in the al-Anbar province, according to both Iraqi witnesses and the U.S. Department of Defence.

    Long stretches of the 550km Baghdad-Amman highway which crosses al-Anbar are now controlled by resistance groups. Other parts are targeted by highway looters.

    "If we import any supplies for the U.S. Army or Iraqi government, the fighters will take it from us and sell it in the local market," trader Hayder al-Mussawi said. "And if we import for the local market, the robbers will take it."

    Eyewitnesses in Ramadi say many of the attacks are taking place within their city. They say that the U.S. military recently asked citizens in al-Anbar to stop targeting them, and promised to withdraw to their bases in Haditha and Habaniyah (near Fallujah) soon, leaving the cities for Iraqi security forces to patrol.

    "I do not think that is possible," retired Iraqi police Brigadier-General Kahtan al-Dulaimi from Ramadi told IPS. "I believe no local unit could stand the severe resistance of al-Anbar, and it will be the last province to be handed over to Iraqi security forces."

    According to the group Iraq Coalition Casualty Count, 964 coalition soldiers have been killed in al-Anbar, more than in any other Iraqi province. Baghdad is second, with 665 coalition deaths.

    Residents of Ramadi told IPS that the U.S. military has knocked down several buildings near the government centre in the city, the capital of the province.

    In an apparent move to secure their offices, U.S. Army and Marine engineers have started to level a half-kilometre stretch of low-rise buildings opposite the centre. Abandoned buildings in this area have been used repeatedly to launch attacks on the government complex.

    "They are trying to create a separation area between the offices of the puppet government and the buildings the resistance are using to attack them," a Ramadi resident said. "But now the Americans are making us all angry because they are destroying our city."

    U.S. troops have acknowledged their own difficulties in doing this. "We’re used to taking down walls, doors and windows, but eight city blocks is something new to us," Marine 1st Lt. Ben Klay, 24, said in the U.S. Department of Defence newspaper Stars and Stripes.

    In nearby Fallujah, residents are reporting daily clashes between Iraqi-U.S. security forces and the resistance.

    "The local police force which used to be out of the conflict are now being attacked," said a resident who gave his name as Abu Mohammed. "Hundreds of local policemen have quit the force after seeing that they are considered a legitimate target by fighters."

    The U.S. forces seem to have no clear policy in the face of the sustained resistance.

    "The U.S. Army seems so confused in handling the security situation in Anbar," said historian Salman. "Attacks are conducted from al-Qa’im on the Syrian border to Abu Ghraib west of Baghdad, all the way through Haditha, Hit, Ramadi and Fallujah on a daily basis."

    He added: "A contributing factor to the instability of the province is the endless misery of the civilians who live with no services, no infrastructure, random shootings and so many wrongful detentions."

    According to the new Pentagon quarterly report on Measuring Security and Stability in Iraq, Iraqi casualties rose 51 percent in recent months. The report says Sunni-based insurgency is "potent and viable."

    The report says that in a period since the establishment of the new Iraqi government, between May 20 and Aug. 11 this year, the average number of weekly attacks rose to nearly 800, almost double the number of the attacks in early 2004.

    Casualties among Iraqi civilians and security forces averaged nearly 120 a day during the period, up from 80 a day reported in the previous quarterly report. Two years ago they were averaging roughly 30 a day.

    On Aug. 31 the Pentagon announced that it is increasing the number of U.S. troops in Iraq to 140,000, which is 13,000 more than the number five weeks ago.

    At least 65 U.S. soldiers were killed in August, with 36 of the deaths reported in al-Anbar. That brought the total number killed to at least 2,642. (END/2006)

  • IMF the world’s viceroy

    The fund is a body with 184 members. It is run by seven of them – the US, Japan, Germany, the UK, France, Canada and Italy. These happen to be the seven countries that (with Russia) promised to save the world at the G8 meeting in 2005. The junta sustains its control by insisting that each dollar buys a vote. The bigger a country’s financial quota, the more say it has over the running of the IMF. This means that it is run by the countries that are least affected by its policies.

    A major decision requires 85% of the vote, which ensures that the US, with 17%, has a veto over the fund’s substantial business. The UK, Germany, France and Japan have 22% between them, and each has a permanent seat on the board. By a weird arrangement permitting rich nations to speak on behalf of the poor, Canada and Italy have effective control over a further 8%. The other European countries are also remarkably powerful: Belgium, for example, has a direct entitlement to 2.1% of the vote and indirect control over 5.1% – more than twice the allocation of India or Brazil. Europe, Japan, Canada and the US wield a total of 63%. The 80 poorest countries, by contrast, have 10% between them.

    These quotas no longer even reflect real financial contributions to the running of the IMF: it now obtains much of its capital from loan repayments by its vassal states. But the G7 nations still behave as if it belongs to them. They decide who runs it (the managing director is always a European and his deputy always an American) and how the money is spent. You begin to wonder why the developing countries bother to turn up.

    In principle, this power is supposed to be balanced by something called the "basic vote" – 250 shares (entitling them to $25m worth of votes) are allocated to every member. But while the value of the rich countries’ quotas has risen since the IMF was founded in 1944, the value of the basic votes has not. It has fallen from 11.3% of the total allocation to 2.1%. The leaked paper passed to me by an excellent organisation called the Bretton Woods Project (everything we know about the IMF has to be leaked) shows that the fund intends to democratise itself by "at least doubling" the basic vote. That sorts it all out, then – the 80 poorest countries will be able to claim, between them, another 0.9%. Even this pathetic concession was granted only after the African members took a political risk by publicly opposing the fund’s proposals. Doubtless the US government is currently reviewing their trading status.

    All this is compounded by an internal political process that looks as if it was contrived in North Korea, not Washington. There are no formal votes, just a "consensus process" controlled by the Dear Leaders of the G7. The decisions taken by each member state cannot be revealed to the public. Nor can the transcripts of the board’s meetings and the "working papers" on which it bases its internal reforms. Even reports by the IMF’s ombudsman – the "independent evaluation office" – are censored by the management, and their conclusions are changed to shift the blame for the fund’s failures to its client states. Needless to say, the IMF insists that the states it lends to must commit themselves to "good governance" and "transparency" if they are to receive its money.

    None of this would matter so much if it had stuck to its original mandate of stabilising the international monetary system. But after the collapse of the Bretton Woods agreement in 1971 the IMF more or less lost its mission to maintain exchange rates, and began to look for a new role. As a paper by the law professor Daniel Bradlow shows, when it amended its articles of asso-ciation in 1978 they were so loosely drafted as to grant the IMF permission to interfere in almost any aspect of a country’s governance. It lost its influence over the economic policies of the G7 and became instead the rich world’s viceroy, controlling the poorer nations at its behest. It began to micro-manage their economies without reference to the people or even their governments. Since then, no rich country has required its services, and few poor countries have been able to shake it off.

    This casts an interesting light on the decision – to be endorsed at the IMF’s meeting in Singapore next week – to enhance the quota for the four middle-income countries. After the fund "helped" the struggling economies of east and south-east Asia in 1997, by laying waste to them on behalf of US hedge funds and investment companies, the nations of that region decided that they would never allow themselves to fall prey to it again.

    They began indemnifying themselves against the fund’s tender loving care by building up their own reserves of capital. Now, just as China and South Korea have ensured that they will never again require the IMF’s services, they have been granted more power to decide how it operates. In other words, they are deemed fit to govern when – like the G7 – they can exercise power without reaping the consequences. The smaller your stake in the outcome, the greater your vote.

    None of this seems to cause any difficulties to the gatekeepers of mainstream opinion. On Saturday a leading article in the Washington Post observed that "to be legitimate, multilateral institutions must reflect the global distribution of power as it is now, not as it was when these institutions were set up more than half a century ago". What a fascinating definition that is, and how wrong we must have been to imagine that legitimacy requires democracy. Hurrah for corporatism – it didn’t die with Mussolini after all.

    I am among those who believe that the IMF is, and always will be, the wrong body – inherently flawed and constitutionally unjust. But if its leaders and supporters are to persuade us that it might, one day, have a legitimate role in running the world’s financial systems, they will have to do a hell of a lot better than this.

  • Climate change evidence in million year old bubbles

    However, existing levels of carbon dioxide and methane are far higher than anything seen during these earlier warm periods, said Eric Wolff of the BAS.

    "Ice cores reveal the Earth’s natural climate rhythm over the last 800,000 years. When carbon dioxide changed there was always an accompanying climate change," Dr Wolff said. "Over the past 200 years, human activity has increased carbon dioxide to well outside the natural range and we have no analogue for what will happen next.

    "We have a no-analogue situation. We don’t have anything in the past that we can measure directly," he added.

    The ice core was drilled from a thick area of ice on Antarctica known as Dome C. The core is nearly 3.2km long and reaches to a depth where air bubbles became trapped in ice that formed 800,000 years ago.

    "It’s from those air bubbles that we know for sure that carbon dioxide has increased by about 35 per cent in the past 200 years. Before that 200 years, which is when man’s been influencing the atmosphere, it was pretty steady to within 5 per cent," Dr Wolff said.

    The core shows that carbon dioxide was always between 180 parts per million (ppm) and 300 ppm during the 800,000 years. However, now it is 380 ppm. Methane was never higher than 750 parts per billion (ppb) in this timescale, but now it stands at 1,780 ppb.

    But the rate of change is even more dramatic, with increases in carbon dioxide never exceeding 30 ppm in 1,000 years — and yet now carbon dioxide has risen by 30 ppm in the last 17 years.

    "The rate of change is probably the most scary thing because it means that the Earth systems can’t cope with it," Dr Wolff told the British Association meeting at the University of East Anglia in Norwich.

    "On such a crowded planet, we have little capacity to adapt to changes that are much faster than anything in human experience."
