Search continues for radioactive Vermont Yankee leak
By Terri Hallenbeck, Free Press Staff Writer • Saturday, January 23, 2010
MONTPELIER — Crews will start drilling more monitoring wells today at Vermont Yankee as the Vernon nuclear power plant’s owners continue the search for the source of a leak of the radioactive isotope tritium.
The tritium leak was revealed three weeks ago after heightened radioactive levels were found in a monitoring well outside the plant. Tests continued this week to show a range of tritium — from 14,000 to 28,100 picocuries per liter, Vermont Yankee spokesman Rob Williams said. The most recent tests were at 20,900, he said.
The Environmental Protection Agency safety standard for tritium in drinking water is 20,000 picocuries per liter.
More heightened levels — as high as 2 million picocuries — have since been found in a concrete trench on the plant’s campus. No heightened levels of radioactive substances have been found in nearby drinking wells that are monitored.
Other radioactive isotopes — cobalt-60 and zinc-65 — have also been found in the trench, which is a locked and confined building where radioactive waste is stored and treated. Williams said Friday that those were found in the Jan. 13 sampling along with tritium.
Neil Sheehan, Nuclear Regulatory Commission spokesman, said 13,000 picocuries per liter of cobalt-60 and 2,460 picocuries of zinc-45 were found in the standing water in the trench. Those are well above federal drinking-water limits of 100 picocuries for cobalt-60 and 300 picocuries for zinc-65. Officials cautioned that the substances aren’t in the drinking water but are in an enclosed part of the nuclear power plant.
Williams said it’s not a surprise to find those other isotopes, nor does the discovery likely help in the search for the source of the leak.
“That’s the kind of material you’d expect to find in the basement of a building that processes nuclear waste,” Williams said. “What we’re looking for is the source of the tritium.”
The leak — and the fact that Vermont Yankee owner Entergy Corp. had told state officials that pipes that might play a role in the leak didn’t exist — have raised concerns about the plant as its owner seeks permission to continue operation for another 20 years after its license expires in 2012. Friday, Vermont’s three-member congressional delegation wrote a letter to the Nuclear Regulatory Commission calling for an immediate investigation.
“This investigation should not only determine whether there was an attempt by Entergy Vermont Yankee to mislead state officials regarding the plant’s safety and underground piping, but also provide a complete and accurate assessment of the full scope of the contamination at and near the plant as soon as possible,” the delegation said.
Meanwhile, Vermont Yankee has constructed a barrier to seal a connection between the trench and an evaporator tank that could be contributing to the accumulation of tritium-contaminated water in the trench, according to the state Health Department, which started posting online updates on the situation Thursday. The seal appears to have stopped condensation of tritium-contaminated water vapor on the corrugated roof over the concrete trench, according to the Health Department.
Engineers are studying the trench’s structural integrity to see if it is contributing to the leak, according to the Health Department.
Also Friday, the NRC extended Entergy’s deadline for spinning off Vermont Yankee and other Northeast nuclear power plants into a new company. Because Entergy has not won approval from Vermont or New York regulators for the move, the deadline has been extended from Jan. 28 to Aug. 1.
ManBearPig Attacked by Science!
By Khephra | Aletho News | January 28, 2010
Today I’d like to more thoroughly address specific planks of Anthropogenic Global Warming Theory (AGW) that I think deserve further scrutiny. Over the past year AGW rhetoric has reached deafening levels, and advocates have successfully framed the hypothesis as unassailable. Propagandists have yolked AGW with “wise stewardship” and today it’s common for skeptics of AGW to be derided as ignorant anti-environmentalists. But I don’t think that things are nearly so simple.
Unfortunately, once people become emotionally invested in a position, it can be very difficult to provoke them into changing course. Liberals and progressives hailed the election of Obama as the most wonderful thing since sliced-bread. With a battlefield full of broken promises behind him and the insinuation of institutionalized corruption and illegal forced detentions stretching into the foreseeable future, many of those same liberals and progressives have fallen into an exasperated, listless complacency. They became emotionally invested in the “hope” engendered by Obama, and when the reality failed to live up to the myth, they were forced into cognitive dissonance, apathy, or synthesis. If you meet someone who still supports Obama, dig a little and you’ll find the cognitive dissonance – and, I would argue, the same could be said of supporters of AGW.
To get us started, I think we should rehash the essential assumptions of AGW:
• As atmospheric levels of C02 increase, Earth’s median temperature increases.
• As Earth’s median temperature increases, atmospheric imbalances precipitate increases in the frequency and strength of weather events (e.g., hurricanes, tornadoes, droughts).
• Humans are directly exacerbating this process through the burning of fossil fuels and any activity that yields C02 as a byproduct.
• Increased median temperatures are melting the polar ice caps and causing glaciers to recede or vanish.
Since AGW has the pleasant benefit of being a bonafide scientific theory, it suggests falsifiable claims. If these claims can be demonstrated invalid, the theory is in need of reconsideration. On the other hand, if emotional investment and cognitive dissonance are high enough, no amount of contradictory data will matter. Young Earth Creationists make a fine example of this psychopathology. In spite of overwhelming tangible evidence that their theory is invalid, they fall back on dogma or the Bible – and no amount of science will provoke them into reconsidering their position. Thankfully, AGW is far easier to invalidate than dogma from the Bible, because it makes so many suppositions that are easily testable.
Let’s begin with the most crucial component of AGW – C02. Here’s a graph of historical global C02 levels and temperatures. According to their analysis:
“Current climate levels of both C02 and global temperatures are relatively low versus past periods. Throughout time, C02 and temperatures have been radically different and have gone in different directions. As this graph reveals, there is little, if any correlation, between an increase of C02 and a resulting increase in temperatures.”
If we realize that C02’s correlation with global temperature is not a given, the entire edifice of AGW begins to crumble. Therefore, it’s difficult to get adherents of AGW to accept the implications of this data. Again and again they’ll fall back on the assumption that the correlation between C02 and global temperatures is incontrovertible, but they must avoid an ever-expanding amount of dissonant data:
MIT’s professor Richard Lindzen’s peer reviewed work states “we now know that the effect of CO2 on temperature is small, we know why it is small, and we know that it is having very little effect on the climate.”
The global surface temperature record, which we update and publish every month, has shown no statistically-significant “global warming” for almost 15 years. Statistically-significant global cooling has now persisted for very nearly eight years. Even a strong el Nino – expected in the coming months – will be unlikely to reverse the cooling trend. More significantly, the ARGO bathythermographs deployed throughout the world’s oceans since 2003 show that the top 400 fathoms of the oceans, where it is agreed between all parties that at least 80% of all heat caused by manmade “global warming” must accumulate, have been cooling over the past six years. That now prolonged ocean cooling is fatal to the “official” theory that “global warming” will happen on anything other than a minute scale. – Science & Public Policy Institute: Monthly CO2 Report: July 2009
“Just how much of the “Greenhouse Effect” is caused by human activity?
It is about 0.28%, if water vapor is taken into account– about 5.53%, if not.
This point is so crucial to the debate over global warming that how water vapor is or isn’t factored into an analysis of Earth’s greenhouse gases makes the difference between describing a significant human contribution to the greenhouse effect, or a negligible one.” – Geocraft
Next, let’s further consider the hypothetical tangential effects of AGW – e.g., rising global temperatures melt icecaps, etc.:
• Climatologists Baffled by Global Warming Time-Out: “Global warming appears to have stalled. Climatologists are puzzled as to why average global temperatures have stopped rising over the last 10 years. Some attribute the trend to a lack of sunspots, while others explain it through ocean currents.”
• ‘AGW – I refute it thus!’: Central England Temperatures 1659 – 2009: “Summary: Unprecedented warming did not occur in central England during the first decade of the 21st century, nor during the last decade of the 20th century. As the CET dataset is considered a decent proxy for Northern Hemisphere temperatures, and since global temperature trends follow a similar pattern to Northern Hemisphere temps, then the same conclusion about recent warming can potentially be inferred globally. Based on the CET dataset, the global warming scare has been totally blown out of proportion by those who can benefit from the fear.”
• 50 Years of Cooling Predicted: “‘My findings do not agree with the climate models that conventionally thought that greenhouse gases, mainly CO2, are the major culprits for the global warming seen in the late 20th century,’ Lu said. ‘Instead, the observed data show that CFCs conspiring with cosmic rays most likely caused both the Antarctic ozone hole and global warming….’
In his research, Lu discovers that while there was global warming from 1950 to 2000, there has been global cooling since 2002. The cooling trend will continue for the next 50 years, according to his new research observations.”
A comparison of GISS data for the last 111 years show US cities getting warmer but rural sites are not increasing in temperature at all. Urban Heat Islands may be the only areas warming.
Rise of sea levels is ‘the greatest lie ever told’:
If there is one scientist who knows more about sea levels than anyone else in the world it is the Swedish geologist and physicist Nils-Axel Mörner, formerly chairman of the INQUA International Commission on Sea Level Change. And the uncompromising verdict of Dr Mörner, who for 35 years has been using every known scientific method to study sea levels all over the globe, is that all this talk about the sea rising is nothing but a colossal scare story.
Despite fluctuations down as well as up, “the sea is not rising,” he says. “It hasn’t risen in 50 years.” If there is any rise this century it will “not be more than 10cm (four inches), with an uncertainty of plus or minus 10cm”. And quite apart from examining the hard evidence, he says, the elementary laws of physics (latent heat needed to melt ice) tell us that the apocalypse conjured up by Al Gore and Co could not possibly come about.
The reason why Dr Mörner, formerly a Stockholm professor, is so certain that these claims about sea level rise are 100 per cent wrong is that they are all based on computer model predictions, whereas his findings are based on “going into the field to observe what is actually happening in the real world”. – Telegraph.co.uk
Since the early Holocene, according to the findings of the six scientists, sea-ice cover in the eastern Chuckchi Sea appears to have exhibited a general decreasing trend, in contrast to the eastern Arctic, where sea-ice cover was substantially reduced during the early to mid-Holocene and has increased over the last 3000 years. Superimposed on both of these long-term changes, however, are what they describe as “millennial-scale variations that appear to be quasi-cyclic.” And they write that “it is important to note that the amplitude of these millennial-scale changes in sea-surface conditions far exceed [our italics] those observed at the end of the 20th century.”
Since the change in sea-ice cover observed at the end of the 20th century (which climate alarmists claim to be unnatural) was far exceeded by changes observed multiple times over the past several thousand years of relatively stable atmospheric CO2 concentrations (when values never strayed much below 250 ppm or much above 275 ppm), there is no compelling reason to believe that the increase in the air’s CO2 content that has occurred since the start of the Industrial Revolution has had anything at all to do with the declining sea-ice cover of the recent past; for at a current concentration of 385 ppm, the recent rise in the air’s CO2 content should have led to a decrease in sea-ice cover that far exceeds what has occurred multiple times in the past without any significant change in CO2. – C02 Science.org

• The Global Warming Scandal Heats Up: “The IPCC has been forced to admit that the claim made was actually taken from an article published in 1999. The article was based around a telephone interview with an Indian scientist who has admitted that he was working from pure speculation and his claims were not backed by research.”
• The Dam is Cracking: “[The claims of Himalayan glacial melting] turned out to have no basis in scientific fact, even though everything the IPCC produces is meant to be rigorously peer-reviewed, but simply an error recycled by the WWF, which the IPCC swallowed whole.
The truth, as seen by India’s leading expert in glaciers, is that “Himalayan glaciers have not in anyway exhibited, especially in recent years, an abnormal annual retreat.” …
Then at the weekend another howler was exposed. The IPCC 2007 report claimed that global warming was leading to an increase in extreme weather, such as hurricanes and floods. Like its claims about the glaciers, this was also based on an unpublished report which had not been subject to scientific scrutiny — indeed several experts warned the IPCC not to rely on it.”
• Arctic Sea Ice Since 2007: “According to the World Meteorological Organization, Arctic sea ice has increased by 19 percent since its minimum in 2007, though they don’t make it very easy to see this in the way that they report the data.”
Now let’s consider some of the agents and institutions that are strong advocates of AGW:
Howard C. Hayden, emeritus professor of physics from the University of Connecticut, told a Pueblo West audience that he was prompted to speak out after a visit to New York where he learned that scaremongering billboards about the long-term effects of global warming were being purchased at a cost of $700,000 a month.
“Someone is willing to spend a huge amount of money to scare us about global warming,” Hayden said. “Big money is behind the global-warming propaganda.”
Lawrence Solomon: Wikipedia’s Climate Doctor:
Connolley took control of all things climate in the most used information source the world has ever known – Wikipedia. Starting in February 2003, just when opposition to the claims of the bands members were beginning to gel, Connolley set to work on the Wikipedia site. He rewrote Wikipedia’s articles on global warming, on the greenhouse effect, on the instrumental temperature record, on the urban heat island, on climate models, on global cooling. On Feb. 14, he began to erase the Little Ice Age; on Aug.11, the Medieval Warm Period. In October, he turned his attention to the hockey stick graph. He rewrote articles on the politics of global warming and on the scientists who were skeptical of the band. Richard Lindzen and Fred Singer, two of the world’s most distinguished climate scientists, were among his early targets, followed by others that the band especially hated, such as Willie Soon and Sallie Baliunas of the Harvard-Smithsonian Center for Astrophysics, authorities on the Medieval Warm Period.
All told, Connolley created or rewrote 5,428 unique Wikipedia articles. His control over Wikipedia was greater still, however, through the role he obtained at Wikipedia as a website administrator, which allowed him to act with virtual impunity. When Connolley didn’t like the subject of a certain article, he removed it — more than 500 articles of various descriptions disappeared at his hand. When he disapproved of the arguments that others were making, he often had them barred — over 2,000 Wikipedia contributors who ran afoul of him found themselves blocked from making further contributions. Acolytes whose writing conformed to Connolley’s global warming views, in contrast, were rewarded with Wikipedia’s blessings. In these ways, Connolley turned Wikipedia into the missionary wing of the global warming movement.” – National Post
The ‘ClimateGate’ scandal that broke a couple of months ago warrants some elaboration, too. For previous posts on this topic, see:
• Using ClimateGate to Reason with ManBearPig
• ClimateGate Crashes ManBearPig’s Party
• ManBearPig Meets the Vikings
• ManBearPig on Life Support?
That foundation established, let’s take a closer look at who was involved with ClimateGate:
For a thorough, email-by-email elaboration of exactly what the ‘big deal’ is, see here:
Climategate publicly began on November 19, 2009, when a whistle-blower leaked thousands of emails and documents central to a Freedom of Information request placed with the Climatic Research Unit of the University of East Anglia in the United Kingdom. This institution had played a central role in the “climate change” debate: its scientists, together with their international colleagues, quite literally put the “warming” into Global Warming: they were responsible for analyzing and collating the various measurements of temperature from around the globe and going back into the depths of time, that collectively underpinned the entire scientific argument that mankind’s liberation of “greenhouse” gases—such as carbon dioxide—was leading to a relentless, unprecedented, and ultimately catastrophic warming of the entire planet.
The key phrase here, from a scientific point of view, is that it is “unprecedented” warming.
• The Proof Behind the CRU ClimateGate Debacle: Because Computers Do Lie When Humans Tell Them Too: “As you can see, (potentially) valid temperature station readings were taken and skewed to fabricate the results the “scientists” at the CRU wanted to believe, not what actually occurred.”
• Unearthed Files Include “Rules” for Mass Mind Control Campaign: “The intruded central computer was not only filled to the brim with obvious and attempted ostracizing of scientists who don’t blindly follow the leader, the files also reveal that the folks of the IPCC made use or considered making use of a disinformation campaign through a ‘communication agency’ called Futerra.
The agency describes itself as ‘the sustainability communications agency’ and serves such global players as Shell, Microsoft, BBC, the UN Environment Programme, the UK government and the list goes on. The co-founder of Futerra, Ed Gillespie explains: ‘For brands to succeed in this new world order, they will have to become eco, ethical and wellness champions.’
The document included within the climategate treasure-chest is called ‘Rules of the Game’ and shows deliberate deception on the part of this agency to ensure that the debate would indeed be perceived as being settled. When facts do not convince, they reasoned, let us appeal to emotions in order to get the job done.”
• Climategate goes SERIAL: now the Russians confirm that UK climate scientists manipulated data to exaggerate global warming: “Climategate has already affected Russia. On Tuesday, the Moscow-based Institute of Economic Analysis (IEA) issued a report claiming that the Hadley Center for Climate Change based at the headquarters of the British Meteorological Office in Exeter (Devon, England) had probably tampered with Russian-climate data.
The IEA believes that Russian meteorological-station data did not substantiate the anthropogenic global-warming theory. Analysts say Russian meteorological stations cover most of the country’s territory, and that the Hadley Center had used data submitted by only 25% of such stations in its reports. Over 40% of Russian territory was not included in global-temperature calculations for some other reasons, rather than the lack of meteorological stations and observations.”
• ClimateGate Expanding, Including Russian Data and Another Research Center: “Well now some Russian climate officials have come forward stating that the data they handed over to the Hadley Centre in England has been cherry-picked, leaving out as much as 40% of the cooler temperature readings and choosing the hottest readings to make it appear things were warmer than they actually are (regardless of whether the temperature is human-induced or natural).”
Scientists using selective temperature data, sceptics say:
Two American researchers allege that U.S. government scientists have skewed global temperature trends by ignoring readings from thousands of local weather stations around the world, particularly those in colder altitudes and more northerly latitudes, such as Canada.
In the 1970s, nearly 600 Canadian weather stations fed surface temperature readings into a global database assembled by the U.S. National Oceanic and Atmospheric Administration (NOAA). Today, NOAA only collects data from 35 stations across Canada.
Worse, only one station — at Eureka on Ellesmere Island — is now used by NOAA as a temperature gauge for all Canadian territory above the Arctic Circle.
The Canadian government, meanwhile, operates 1,400 surface weather stations across the country, and more than 100 above the Arctic Circle, according to Environment Canada. – Canada.com
The ClimateGate emails were highly damning, and have led to Phil Jones’ (one of the researchers at the centre of the scandal) resignation and an investigation into Michael Mann’s ’scholarship’. Furthermore, the UN is also ‘investigating’ the ’scholarship’ underlying the scandal, but if something as incontrovertible as the Goldstone Report can get whitewashed, I have little hope for a meaningful or just analysis in a scandal of this magnitude. In theory, science is self-correcting; but in practice it’s “defend your thesis at all costs”.
Nevertheless, each of our original four suppositions are demonstrably ambiguous – if not outright invalid. Therefore, science – and empiricism – invalidates AGW.
Humanity has irrevocably altered – blighted? – the Earth, but C02 levels are far less relevant than other forms of industrial pollution: mercury-seeping lightbulbs, dioxin pollution, gene drift, cell phone-induced genetic damage, and all manner of other harmful and silly endeavours pose greater unambiguous threats to humanity than C02. Therefore, if you really want to help clean up the Earth, leave the AGW rhetoric in the dustbin and let’s get on with disempowering the hegemons.

Coral in Florida Keys suffers lethal hit from cold
By Curtis Morgan | The Miami Herald | January 27, 2010
A diver surveys dead coral at an Upper Keys reef. ‘Ecosystem-wide mortality,’ says Meaghan Johnson of The Nature Conservancy. Bitter cold this month may have wiped out many of the shallow water corals in the Keys. Scientists have only begun assessments, with dive teams looking for “bleaching” that is a telltale indicator of temperature stress in sensitive corals, but initial reports are bleak. The impact could extend from Key Largo through the Dry Tortugas west of Key West, a vast expanse that covers some of the prettiest and healthiest reefs in North America.
Given the depth and duration of frigid weather, Meaghan Johnson, marine science coordinator for The Nature Conservancy, expected to see losses. But she was stunned by what she saw when diving a patch reef 2 ½ miles off Harry Harris Park in Key Largo.
Star and brain corals, large species that can take hundreds of years to grow, were as white and lifeless as bones, frozen to death. There were also dead sea turtles, eels and parrotfish littering the bottom.
“Corals didn’t even have a chance to bleach. They just went straight to dead,” said Johnson, who joined teams of divers last week surveying reefs in the Florida Keys National Marine Sanctuary. “It’s really ecosystem-wide mortality.”
The record chill that gripped South Florida for two weeks has taken a heavy toll on wildlife — particularly marine life.
On Tuesday, the Florida Fish and Wildlife Conservation Commission reported that record numbers of endangered manatees had already succumbed to the cold this year — 77, according to a preliminary review. The previous record, 56, was set last year. Massive fish kills also have been reported across the state. Carcasses of snook and tarpon are still floating up from a large fish kill across Florida Bay and the shallow waters of Everglades National Park.
Many of the Florida Keys’ signature diving destinations such as Carysfort, Molasses and Sombrero reefs — as well as deeper reefs off Miami-Dade and Broward — are believed to have escaped heavy losses, thanks to warming effects of the Gulf Stream. But shallower reefs took a serious, perhaps unprecedented hit, said Billy Causey, Southeast regional director of national marine sanctuaries for the National Oceanic and Atmospheric Administration.
PAST PROBLEMS
Coral-bleaching has struck the Keys in the past, most recently twice in the 1990s, preceding a die-off that claimed 30 percent of the reef tract. But those events, along with others that have hit reefs around the world, have usually been triggered by water hotter than what corals typically tolerate.
Healthy corals depend on a symbiotic relationship between polyps, the living tissues that slowly build the hard outer skeletons that give species distinctive shapes, and algae called zooxanthellae that give them their vibrant colors. But when ocean temperatures veer from their comfort zone too much or too long, the coral begin to shed that algae, turning dull or a bleached bone-white.
The effect usually doesn’t immediately kill coral but can weaken it, slowing growth and leaving fragile reefs — home to millions of fish, crabs and other animals — more vulnerable to diseases, pollution and damage from boaters and divers.
Cold-water bleaching is unusual, last occurring in 1977, the year it snowed in Miami. It killed hundreds of acres of staghorn and elkhorn corals across the Keys. Neither species has recovered, both becoming the first corals to be federally listed as threatened in 2006.
This big chill, said Causey, shapes up worse.
“They were exposed to temperatures much colder, that went on longer, than what they were exposed to three decades ago,” he said.
Typical winter lows in-shore hover in the mid- to high-60s in the Keys.
At its coldest more than a week ago, a Key Largo reef monitor recorded 52. At Munson Reef, just about a half-mile off the Newfound Harbor Keys near Big Pine Key, it hit 56.
At Munson Reef, said Cory Walter, a biologist for Mote Marine Laboratory in Summerland Key, scientists saw losses similar to what was reported off Key Largo. Dead eels, dead hogfish, dead coral — including big coral head five- to six-feet wide, bleached white with only fringes of decaying tissue.
“They were as big, as tall, as me. They were pretty much dead,” said Walter, who coordinates Mote’s BleachWatch program, which monitors reefs.
The dividing line for damage seems to be Hawk Channel, which parallels the Keys on the Atlantic Ocean side.
East of the channel, at reefs such as Looe Key, one of the top tourist sites, there was only light paling on some coral, she said. In Hawk Channel itself, there were dead sponges and stressed corals but not many outright dead ones.
SURVEYING DAMAGE
West of the channel toward shore, damage was more serious. Walter estimated 75 percent coral loss at one patch reef, though with poor visibility, it was a limited survey. Some nurseries growing small staghorn and elkhorn corals for restoration programs also may have been hard hit.
Over the next few weeks, scientists and divers from the Florida Keys National Marine Sanctuary, National Park Service, Florida Fish & Wildlife Conservation Commission, Mote Marine Laboratory, the University of Miami, Nova Southeastern University and other organizations will try to get a more completepicture of damage with reef surveys as far northas Martin County and as far south as the Dry Tortugas.
While they may not be able to save cold-damaged corals, Causey said, chronicling what dies and, more importantly, what survives, will help coral researchers in the future.
“We’re going to know so much more about this event than any other event in history,” he said.

Report finds high rate of thyroid cancer in eastern Pa.; blames nuclear power plants
By REGINA MEDINA | Philadelphia Daily News | January 24, 2010
Residents of eastern Pennsylvania might not know it, but they’re living in the middle of a thyroid-cancer hot spot, according to a public-health advocate.
The eastern side of the state lays claim to six of the nation’s top 18 counties with the highest thyroid-cancer rates, according to figures from the Centers for Disease Control and Prevention.
Pennsylvania ranked as the No. 1 state in thyroid-cancer cases between 2001 and 2005, 12.8 cases per 100,000 residents. (New Jersey comes in at No. 5 with 11.8 cases per 100,000.)
Joseph Mangano, the executive director of the Radiation and Public Health Project research group, said yesterday that he believes the spike in cancer is due to the high number of nuclear plants in the area.
At a news conference at City Hall where thyroid-cancer survivors and physicians also spoke, Mangano said that within 100 miles of eastern Pennsylvania, 16 nuclear reactors are operating at seven nuclear plants, the highest concentration in the country.
The emissions from the Limerick and Three-Mile Island plants don’t come close to those from the 1945 bombing of Hiroshima or the 1986 Chernobyl accident, but “that doesn’t necessarily mean [it’s] safer,” Mangano said.
“Not only have we documented an epidemic of thyroid cancer in the area, but we have raised a red flag for more and more detailed study of the relationship between the reactor emissions and thyroid cancer,” Mangano said.
Mangano, who published his findings in the International Journal of Health Services, said that the only known cause of thyroid cancer is exposure to radiation, specifically radioactive iodine, “one of the 100 man-made chemicals” produced by nuclear energy.
One University of Pennsylvania doctor who has researched thyroid cancer called the findings “provocative” and “intriguing,” but added that the author needed to delve more into the subject.
“We do know nuclear plants give off radioactive iodine [and] radioactive iodine can be associated with thyroid cancer,” said Susan J. Mandel, a professor of medicine and radiology. “Does it mean it causes it? It requires further investigation to see if it’s causing it.”
Lehigh County had the highest thyroid-cancer rate; others in eastern Pennsylvania were: Northampton (3rd), Luzerne (6th), York (7th), Bucks (14th) and Lancaster (18th). In New Jersey, Camden was ranked No. 16 and Burlington was 17th.
Climate science: models vs. observations

If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence.
— Bertrand Russell, Roads to Freedom, 1918
Science and models
True science begins with observations. When patterns are recognized in these observations, that leads to theories and models, which then lead to predictions. The predictions can then be tested by further observations, which can validate or invalidate the theories and models, or be used to refine them.
This is the paradigm accepted by all scientists. But scientists being people, typically in an academic research community, within a political society, there can be many a slip between cup and lip in the practice of science. There are the problems of getting funding, of peer pressure and career considerations, of dominant political dogmas, etc.
In the case of models there is a special problem that frequently arises. Researchers tend to become attached to their models, both psychologically and professionally. When new observations contradict the model, there is a tendency for the researchers to distort their model to fit the new data, rather than abandoning their model and looking for a better one. Or they may even ignore the new observations, and simply declare that their model is right, and the observations must be in error. This problem is even worse with complex computer models, where it is difficult for reviewers to figure out how the model really works, and whether ’fudging’ might be going on.
A classic example of the ’attached to model’ problem can be found in models of the universe. The Ptolemaic model assumed that the Earth is the center of the universe, and that the universe revolves around that center. Intuitively, this model makes a lot of sense. On the Earth, it feels like we are stationary. And we see the Sun and stars moving across the sky. “Obviously” the universe revolves around the Earth.
However, in order for this model to work in the case of the planets, it was necessary to introduce the arbitrary mechanism of epicycles. When Galileo and Copernicus came along, a much cleaner model was presented, that explained all the motions with no need for arbitrary assumptions. But no longer would the Earth be the center.
In this case it was not so much scientists that were attached to the old model, but the Church, which liked the model because it fit their interpretation of scripture. We’ve all heard the story of the Bishop who refused to look through the telescope, so he could ignore the new observations and hold on to the old model. Galileo was forced to recant. Thus can political interference hold back the progress of science, and ruin careers.
Climate models and global warming
Over the past century there has been a strong correlation between rising temperatures, and rising CO2 levels in the atmosphere, caused by the ever-increasing burning of fossil fuels. And it is well known that CO2 is a greenhouse gas. Other things being equal, higher CO2 levels must cause an increase in temperature, due to trapping more heat from the sun. Many scientists, quite reasonably, began to explore the theory that continually rising CO2 emissions would lead to continually rising temperatures.
Intuitively, it seems that the theory is “obviously” true. Temperatures have been rising along with CO2 levels; CO2 is a greenhouse gas; what is there to prove? And if the theory is true, and we keep increasing our emissions, then temperatures will eventually reach dangerous levels, melting the Antarctic ice sheet, raising sea levels, and all the other disasters presented by Al Gore in his famous documentary. “Obviously” we are facing a human-generated crisis – and something has got to be done!
But for many years, before Gore’s film, governments didn’t seem to be listening. Environmentalists, however, were listening. Public concern began to grow about CO2 emissions, and the climate scientists investigating the theory shared these concerns. They had a strong motivation to present the scientific case convincingly, in order to force governments to pay attention and take effective action — the future of humanity was at stake!
The climate scientists began building computer models, based on the observed correlation between temperature and CO2 levels. The models looked solid, not only for the past century, but extending back in time. Research with ice-core data revealed a general correlation between temperature and CO2 levels, extending back for a million years and more. What had been “obvious” to begin with, now looked even more obvious, confirmed by seemingly solid science.
These are the very conditions that typically cause scientists to become attached to their models. The early success of the model confirms what the scientists suspected all along: the theory must be true. A subtle shift happens in the mind of the scientists involved. What began as a theory starts to become an assumption. If new data seems to contradict the theory, the response is not to discard the theory, but rather to figure out what the model is lacking.
In the case of the Ptolemaic model, they figured out that epicycles must be lacking, and so epicycles were added. They were certain the universe revolved around the Earth, and so epicycles had to exist. Similarly, the climate scientists have run into problems with their models, and they’ve needed to add more and more machinery to their models in order to overcome those problems. They are certain of their theory, and so their machinery must be valid.
Perhaps they are right. Or perhaps they’ve strayed into epicycle territory, where the theory needs to be abandoned and a better model needs to be identified. This is the conclusion that quite a few scientists have reached. Experts do differ on this question, despite the fact that Gore says emphatically that the “science is settled”. Which group of scientists is right? This is the issue we will be exploring in this article.
Question 1
Compared to the historical record, are we facing a threat of dangerous global warming?
Let’s look at the historical temperature record, beginning with the long-term view. For long-term temperatures, ice-cores provide the most reliable data. Let’s look first at the very-long-term record, using ice cores from Vostok, in the Antarctic.
Data source:
ftp://ftp.ncdc.noaa.gov/pub/data/paleo/icecore/antarctica/vostok/deutnat.txt
Vostok Temperatures: 450,000 BC — Present
Here we see a very regular pattern of long-term temperature cycles. Most of the time the Earth is in an ice age, and about every 125,000 years there is a brief period of warm tempertures, called an inter-glacial period. Our current inter-glacial period has lasted a bit longer than most, indicating that the next ice age is somewhat overdue. These long-term cycles are probably related to changes in the eccentricity of the Earth’s orbit, which follows a cycle of about 100,000 years.
We also see other cycles of more closely-spaced peaks, and these are probably related to other cycles in the Earth’s orbit. There is an obliquity cycle of about 41,000 years, and a precession cycle, of about 20,000 years, and all of these cycles interfere with one another in complex ways. Here’s a tutorial from NASA that discusses the Earth’s orbital variations:
http://www-istp.gsfc.nasa.gov/stargaze/Sprecess.htm
Next let’s zoom-in on the current inter-glacial period, as seen in Vostok and Greenland, again using ice-core data. Temperatures here are relative to the value for 1900, which is shown as zero:
Vostok Temperatures: 12,000 BC — 1900
Data source:
http://www.ncdc.noaa.gov/paleo/metadata/noaa-icecore-2475.html
Greenland Temperatures: 9,500 BC — 1900
Here we see that the Southern Hemisphere emerged from the last ice age about 1,000 years earlier than did the Northern Hemisphere. As of 1900, in comparison to the whole inter-glacial period, the temperature was 3°C below the maximum in Vostok, and 3°C below the maximum in Greenland. Thus, as of 1900, temperatures were rather cool for the period in both hemispheres, and in Greenland, temperatures were close to a minimum.
During this recent inter-glacial period, temperatures in both Vostok and Greenland have oscillated through a range of about 4°C, although the patterns of oscillation are quite different in each case. In order to see just how different the patterns are, let’s look at Greenland and Vostok together, for the period 500BC–1900. Vostok is shown with a feint line, actually a dotted line if you click to see the enlarged version.
The patterns are very different indeed. In many cases we see an extreme high in Greenland, while at the same time Vostok is experiencing an extreme low. And in the period 1500—1900, while Greenland temperatures were relatively stable, within a range of .5°C, Vostok went through a radical oscillation of 3°C, from an extreme high to an extreme low. These differences between the two hemispheres might be related to the Earth’s orbit (See NASA tutorial), or they might be related to the fact that the Southern Hemisphere is dominated by oceans, while most of the land mass is in the Northern Hemisphere. Whatever the reason, the difference is striking.
There may be some value in trying to average these different records, to obtain a ’global average’, but it is important to understand that a global average is not the same as a global temperature. For example, consider temperatures 2,000 years ago. Greenland was experiencing a very wram period, 2°C above the baseline, while Vostok was experiencing a cold spell, nearly 1°C below the baseline. While the average for year 1000 might be near the baseline, that average does not represent the real temperature in either location.
This distinction between a global average, and real temperatures, is very important to keep in mind. Consider for example the concern that warming might lead to melting of the tundra in the Arctic, leading to the runaway release of methane. If that happens, it must happen in the Arctic. So it is the temperature in the Arctic that is relevant, not any kind of global average. In Greenland, temperatures 2,000 years ago were a full 2°C higher than 1900 temperatures, and there was no runaway release of methane.
The fact that the global average 2,000 years ago was dragged down by Antarctic cooling is completely irrelevant to the issue of melting tundra. Temperatures in the Arctic must rise by more than 2°C above 1900 levels before tundra-melting might be a problem, and this fact is obscured when we look at the global-average-derived hockey stick put out by the IPCC:
This graph gives the impression that temperatures 2,000 years ago were relatively low, and that in 1900 temperatures were higher than that. This may have some kind of abstract meaning, but it has nothing to do with what’s been going on in the Arctic, and it is very misleading as regards the likelihood of tundra-melting, or Arctic-melting in general. The graph is a gross misrepresentation of what’s been happening in the real world. It obscures the actual temperature record in both hemispheres, by presenting an artifical average that has existed nowhere.
Let’s now look at some other records from the Northern Hemisphere, to find out how typical the Greenland record is of its hemisphere. This first record is from Spain, based on the mercury content in a peat bog, as published in Science, 1999, vol. 284, for the most recent 4,000 years. Note that this graph is backwards, with present day on the left:
This next record is from the Central Alps, based on stalagmite isotopes, as published in Earth and Planteary Science Letters, 2005, vol. 235, for the most recent 2,000 years:
And finally, let’s include our Greenland record for the most recent 4,000 years:
While the three records are clearly different, they do share certain important characteristics. In each case we see a staggered rise, followed by a staggered decline — a long-term up-and-down cycle over the period. In each case we see that during the past few thousand years, temperatures have been 3°C higher than 1900 temperatures. And in each case we see a gradual descent towards the overdue next ice age. The Antarctic, on the other hand, shares none of these characteristics.
If we want to understand warming-related issues, such as tundra-melting and glacier-melting, we must consider the two hemispheres separately. If glaciers melt, they do so either because of high northern termperatures, or high southern temperatures. Whether or not glaciers are likely to melt cannot be determined by global averages. In this article we will concern ourselves with the Northern Hemisphere.
In the Northern Hemisphere, based on the shared characteristics we have observed, temperatures would need to rise at least 3°C above 1900 levels before we would need to worry about things like the extinction of polar bears, the melting of the Greenland ice sheet, or runaway methane release. We know this because none of these things have happened in the past 4,000 years, and temperatures have been3°C higher during that period.
However such a 3°C rise seems very unlikely to happen, given that all three of our Nothern Hemisphere samples show a gradual but definite decline toward the overdue next ice age. Let’s now zoom in the temperature record since 1900, and see what kind of rise has actually occurred. Let’s turn to Jim Hansen’s latest article, published on realclimate.org, 2009 temperatures by Jim Hansen. The article includes the following two graphs.
Jim Hansen is of course one of the primary proponents of the CO2-dangerous-warming theory, and there is considerable reason to believe these graphs show an exaggerated picture as regards to warming. Here is one article relevant to that point, and it is typical of other reports I’ve seen:
Son of Climategate! Scientist says feds manipulated data
Nonetheless, let’s accept these graphs as a valid representation of recent temperature changes, so as to be as fair as possible to the warming alarmists. We’ll be using the red line, which is from GISS, and which does not use the various extrapolations that are included in the green line. We’ll return to this topic later, but for now suffice it to say that these extrapolations make little sense from a scientific perspective.
The red line shows a temperature rise of .7°C from 1900 to the 1998 maximum, a leveling off beginning in 2001, and then a brief but sharp decline starting in 2005. Let’s enter that data into our charting program, using values for each 5-year period that represent the center of the oscillations for that period. Here’s what we get for 1900-2008:
Consider the downward trend at the right end of the graph. Hansen tells us this is very temporary, and that temperatures will soon start rising again. Perhaps he is right. However, as we shall see, his arguments for this prediction are seriously flawed. What we know for sure is that a downward trend has begun. How far that trend will continue is not yet known.
Next, let’s append that latest graph to the Greenland data, to get a reasonable characterization of Northern Hemisphere temperatures from 2000 BC to 2008:
This graph shows us that the temperature rise in the Northern Hemipshpere from 1800 to 2005 was not at all unnatural. That rise follows precisely the long-term pattern, where such rises have been occurring approximately every 1,000 years, with no help from human-caused CO2. Based on the long-term pattern of diminishing peaks, we would expect the recent down-trend to continue, and not turn upward again as Hansen predicts. If the natural pattern continues, then the recent warming has reached its maximum, and we will soon experience about two centuries of rapid cooling, as we continue our descent to the overdue next ice age.
So everything depends on the next decade or so. If temperatures turn upwards again, then the IPCC may be right, and human-caused CO2 emissions may have taken control of climate. However, if temperatures continue downward, then climate has been following natural patterns all along in the Northern Hemisphere. In this case there has been no evidence of any noticeable influence on climate from human-caused CO2, and we are now facing an era of rapid cooling. Within two centuries we could expect temperatures in the Northern Hemisphere to be consideralby lower than they were in the recent Little Ice Age.
We don’t know for sure which way temperatures will go, rapidly up or rapidly down. But I can make this statement:
As of this moment, based on the long-term temperature patterns in the Northern Hemisphere, there is no evidence that human-caused CO2 has had any effect on climate. The rise since 1800, as well as the downward dip starting in 2005, are entirely in line with the natural long-term pattern. If temperatures turn sharply upwards in the next decade or so, that will be the first-ever evidence for human-caused warming in the Northern Hemisphere.
As regards the the recent downturn, here are two other records, both of which show an even more dramatic downturn than the one shown in the GISS data:
University of Alabama, Huntsville (UAH)
Dr. John Christy
UAH Monthly Means of Lower Troposphere LT5-2
2004 – 2008
Remote Sensing Systems of Santa Rosa, CA (RSS)
RSS MSU Monthly Anomaly – 70S to 82.5N (essentially Global)
2004 – 2008
Based on the data we have looked at, all from mainstream scientific sources, we are now in a position to answer our first question with a reasonable level of confidence:
Answer 1
Temperatures, at least in the Northern Hemisphere, have been continuing to follow natural, long-term patterns — despite the unusually high levels of CO2 caused by the burning of fossil fuels. There have indeed been two centuries of global warming, and that is exactly what we would expect based on the natural pattern. Temperatures now are more than 2°C cooler than they were only 2,000 years ago, which means we have not been experiencing dangerously high temperatures in the Northern Hemisphere.
The illusion of global warming arises from a failure to recognize that global averages are are a very poor indicator of actual conditions in either hemisphere.
Within the next decade, or perhaps sooner, we are likely to learn which way the climate is going. If it turns again sharply upwards, as Hansen predicts, that will be counter to the long-term pattern, and evidence for human-caused warming. If it levels off, and continues downwards, that is consistent with long-term patterns, and we are likely to experience about two centuries of rapid cooling in the Northern Hemisphere, as we continue our descent toward the overdue next ice age.
Question 2
Why haven’t unsually high levels of CO2 significantly affected temperatures in the Northern Hemisphere?
One place to look for answers to this question is in the long-term patterns that we see in the temperature record of the past few thousand years, such as the peaks separated by about 1,000 years in the Greenland data, and other more closely-spaced patterns that are also visible. Some forces are causing those patterns, and whatever those forces are, they have nothing to do with human-caused CO2 emissions. Perhaps the forces have to do with cycles in solar radiation and solar magnetism, or perhaps they have something to do with cosmic radiation on a galactic scale, or something we haven’t yet identified. Until we understand what those forces are, how they intefere with one another, and how they effect climate, we can’t really build useful climate models, except on very short time scales.
We can also look for answers in the regulatory mechanisms that exist within the Earth’s own climate system. If an increment of warming happens on the surface, for example, then there is more evaporation from the oceans and more precipitation. While an increment of warming may melt glaciers, it may also cause increased snowfall in the arctic regions. Do these balance each other or not? Increased warming of the ocean’s surface may gradually heat the ocean, but the increased evaporation acts to cool the ocean. Do these balance each other?
Vegetation also acts as a regulatory system. Plants and trees gobble up CO2; that is where their substance comes from. Greater CO2 concentration leads to faster growth, taking more CO2 out of the atmosphere. Until we understand quantitively how these various regulatory systems function and interact, we can’t even build useful models on a short time scale.
In fact a lot of research is going on, investigating both lines of inquiry. However, in the current public-opinion and media climate, any research not related to CO2 causation is dismissed as the activity of contrarians, deniers, and oil-company hacks. Just as the Bishop refused to look through Galileo’s telescope, so today we have a whole society that refuses to look at many of the climate studies that are available.
I’d like to draw attention to one example of a scientist who has been looking at one aspect of the Earth’s regulatory system. Roy Spencer has been conducting research using the satellite systems that are in place for climate studies. Here are his relevant qualifications:
http://en.wikipedia.org/wiki/Roy_Spencer_(scientist)
Roy W. Spencer is a principal research scientist for the University of Alabama in Huntsville and the U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer (AMSR-E) on NASA’s Aqua satellite. He has served as senior scientist for climate studies at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
He describes his research in a presentation available on YouTube:
http://www.youtube.com/watch?v=xos49g1sdzo&feature=channel
In the talk he gives a lot of details, which are quite interesting, but one does need to concentrate and listen carefully to keep up with the pace and depth of the presentation. He certainly sounds like someone who knows what he’s talking about. Permit me to summarize the main points of his research:
When greenhouse gases cause surface warming, a response occurs, a ‘feedback response’, in the form of changes in cloud and precipitation patterns. The CRU-related climate models all assume the feedback response is a positive one: any increment of greenhouse warming will be amplified by knock-on effects in the weather system. This assumption then leads to the predictions of ‘runaway global warming’.
Spencer set out to see what the feedback response actually is, by observing what happens in the cloud-precipitation system when surface warming is occurring. What he found, by targeting satellite sensors appropriately, is that the feedback response is negative rather than positive. In particular, he found that the formation of storm-related cirrus clouds is inhibited when surface temperatures are high. Cirrus clouds are themselves a powerful greenhouse gas, and this reduction in cirrus cloud formation compensates for the increase in the CO2 greenhouse effect.
This is the kind of research we need to look at if we want to build useful climate models. Certainly Spencer’s results need to be confirmed by other researchers before we accept them as fact, but to simply dismiss his work out of hand is very bad for the progress of climate science. Consider what the popular website SourceWatch says about Spencer.
We don’t find there any reference to rebuttals to his research, but we are told that Spencer writes columns for a free-market website funded by Exxon. They also mention that he spoke at conference organized by the Heartland Institute, that promotes lots of reactionary, free-market principles. They are trying to discredit Spencer’s work on irrelevant grounds, what the Greeks referred to as an ad hominem argument. Sort of like, “If he beats his wife, his science must be faulty”.
And it’s true about ‘beating his wife’ — Spencer does seem to have a pro-industry philosophy that shows little concern for sustainability. That might even be part of his motivation for undertaking his recent research, hoping to give ammunition to pro-industry lobbyists. But that doesn’t prove his research is flawed or that his conclusions are invalid. His work should be challenged scientifically, by carrying out independent studies of the feedback process. If the challenges are restricted to irrelevant attacks, that becomes almost an admission that his results, which are threatening to the climate establishment, cannot be refuted. He does not hide his data, or his code, or his sentiments. The same cannot be said for the warming-alarmist camp.
Question 3
What are we to make of Jim Hansen’s prediction that rapid warming will soon resume?
Once again, I refer you to Dr. Hansen’s recent article, 2009 temperatures by Jim Hansen.
Jim begins with the following paragraph:
The past year, 2009, tied as the second warmest year in the 130 years of global instrumental temperature records, in the surface temperature analysis of the NASA Goddard Institute for Space Studies (GISS). The Southern Hemisphere set a record as the warmest year for that half of the world. Global mean temperature, as shown in Figure 1a, was 0.57°C (1.0°F) warmer than climatology (the 1951-1980 base period). Southern Hemisphere mean temperature, as shown in Figure 1b, was 0.49°C (0.88°F) warmer than in the period of climatology.
The Southern Hemisphere may be experiencing warming, but it has 2°C to go before that might become a problem there, and it has nothing to do with the Northern Hemisphere, where temperatures have been declining recently, not setting records for warming. This mathematical abstraction, the global average, is characteristic of nowhere. It creates the illusion of a warming crisis, when in fact no evidence for such a crisis exists. In the context of IPCC warnings about glacers melting, runaway warming, etc., this global-average argument serves as deceptive and effective propaganda, but not as science.
Jim continues with this paragraph, emphasis added:
The global record warm year, in the period of near-global instrumental measurements (since the late 1800s), was 2005. Sometimes it is asserted that 1998 was the warmest year. The origin of this confusion is discussed below. There is a high degree of interannual (year‐to‐ year) and decadal variability in both global and hemispheric temperatures. Underlying this variability, however, is a long‐term warming trend that has become strong and persistent over the past three decades. The long‐term trends are more apparent when temperature is averaged over several years. The 60‐month (5‐year) and 132 month (11‐year) running mean temperatures are shown in Figure 2 for the globe and the hemispheres. The 5‐year mean is sufficient to reduce the effect of the El Niño – La Niña cycles of tropical climate. The 11‐ year mean minimizes the effect of solar variability – the brightness of the sun varies by a measurable amount over the sunspot cycle, which is typically of 10‐12 year duration.
As I’ve emphasized in bold, Jim is assuming that there is a strong and persistent warming trend, which he of course attributes to human-caused CO2 emissions. And then that assumption becomes the justification for the 5 and 11-year running averages. Those running averages then give us phantom ’temperatures’ that don’t match actual observations. In particular, if a downard decline is beginning, the running averages will tend to ‘hide the decline’.
It seems we are looking at a classic case of over-attachment to model. What began as a theory has now become an assumption, and actual observations are being dismissed as “confusion” because they don’t agree with the model. The climate models have definitely strayed into the land of imaginary epicycles. The assumption of CO2 causation, plus the preoccupation with an abstract global average, creates a warming illusion that has no connection with reality in either hemisphere, as we see in these two graphs from Jim’s article:
As with the Ptolemaic model, there is a much simpler explantation for our recent era of warming , at least in the Northern Hemisphere: long term patterns are continuing, for whatever reasons, and human-caused CO2 has so far had no noticeable effect. This simpler explanation is based on actual observations, and requires no abstract mathematical epicycles or averages, but it removes CO2 from the center of the climate debate. And just as powerful forces in Galileo’s day wanted the Earth to remain the center of the universe, powerful forces today want CO2 to remain at the center of climate debate, and global warming to be seen as a threat.
Question 4
What is the real agenda of the politically powerful factions who are promoting global-warming alarmism?
One thing we always need to keep in mind is that the people at the top of the power pyramid in our society have access to the very best scientific information. They control dozens, probably hundreds, of high-level think tanks, able to hire the best minds, and carrying out all kinds of research we don’t hear about. They have access to all the secret military and CIA research, and a great deal of influence over what research is carried out in think tanks, the military, and in universities.
Just because they might be promoting fake science for its propaganda value, that doesn’t mean they believe it themselves. They undoubtedly know that global cooling is the real problem, and the actions they are promoting are completely in line with such an understanding.
Cap-and-trade, for example, won’t reduce carbon emissions. Rather it is a mechanism that allows emissions to continue, while pretending they are declining — by means of a phony market model. You know what a phony market model looks like. It looks like Reagan and Thatcher telling us that lower taxes will lead to higher government revenues due to increased business activity. It looks like globalization, telling us that opening up free markets will “raise all boats” and make us all prosperous. It looks like Wall Street, telling us that mortgage derivatives are a good deal, and we should buy them. And it looks like Wall Street telling us the bailouts will restore the economy, and that the recession is over. In short, it’s a con. It’s a fake theory about what the consequences of a policy will be, when the real consequences are known from the beginning.
Cap-and-trade has nothing to do with climate. It is part of a scheme to micromanage the allocation of global resources, and to maximize profits from the use of those resources. Think about it. Our ‘powerful factions’ decide who gets the initial free cap-and-trade credits. They run the exchange market itself, and can manipulate the market, create derivative products, sell futures, etc. They can cause deflation or inflation of carbon credits, just as they can cause deflation or inflation of currencies. They decide which corporations get advance insider tips, so they can maximize their emissions while minimizing their offset costs. They decide who gets loans to buy offsets, and at what interest rate. They decide what fraction of petroleum will go to the global North and the global South. They have ‘their man’ in the regulation agencies that certify the validity of offset projects. And they make money every which way as they carry out this micromanagement.
In the face of global cooling, this profiteering and micromanagenent of energy resources becomes particularly significant. Just when more energy is needed to heat our homes, we’ll find that the price has gone way up. Oil companies are actually strong supporters of the global-warming bandwagon, which is very ironic, given that they are funding some of the useful contrary research that is going on. Perhaps the oil barrons are counting on the fact that we are suspicious of them, and asssume we will discount the research they are funding, as most people are in fact doing. And the recent onset of global cooling explains all the urgency to implement the carbon-management regime: they need to get it in place before everyone realizes that warming alarmism is a scam.
And then there’s the carbon taxes. Just as with income taxes, you and I will pay our full share for our daily commute and for heating our homes, while the big corporate CO2 emitters will have all kinds of loopholes, and offshore havens, set up for them. Just as Federal Reserve theory hasn’t left us with a prosperous Main Street, despite its promises, so theories of carbon trading and taxation won’t give us a happy transition to a sustainable world.
Instead of building the energy-efficient transport systems we need, for example, they’ll sell us biofuels and electric cars, while most of society’s overall energy will continue to come from fossil fuels, and the economy continues to deteriorate. The North will continue to operate unsustainably, and the South will pay the price in the form of mass die-offs, which are already ticking along at the rate of six million children a year from malnutrition and disease.
While collapse, suffering, and die-offs of ‘marginal’ populations will be unpleasant for us, it will give our ‘powerful factions’ a blank canvas on which to construct their new world order, whatever that might be. And we’ll be desperate to go along with any scheme that looks like it might put food back on our tables and warm up our houses.

Up in Smoke
Why Biomass Wood Energy is Not the Answer
By George Wuerthner | January 12, 2010
After the Smurfit-Stone Container Corp.’s linerboard plant in Missoula Montana announced that it was closing permanently, there have been many people including Montana Governor Switzer, Missoula mayor and Senator Jon Tester, among others who advocate turning the mill into a biomass energy plant. Northwestern Energy, a company which has expressed interest in using the plant for energy production has already indicated that it would expect more wood from national forests to make the plant economically viable.
The Smurfit Stone conversion to biomass is not alone. There have been a spate of new proposals for new wood burning biomass energy plants sprouting across the country like mushrooms after a rain. Currently there are plans and/or proposals for new biomass power plants in Maine, Vermont, Pennsylvania, Florida, California, Idaho, Oregon and elsewhere. In every instance, these plants are being promoted as “green” technology.
Part of the reason for this “boom” is that taxpayers are providing substantial financial incentives, including tax breaks, government grants, and loan guarantees. The rationale for these taxpayer subsidies is the presumption that biomass is “green” energy. But like other “quick fixes” there has been very little serious scrutiny of real costs and environmental impacts of biomass. Whether commercial biomass is a viable alternative to traditional fossil fuels can be questioned.
Before I get into this discussion, I want to state right up front, that coal and other fossil fuels that now provide much of our electrical energy need to be reduced and effectively replaced. But biomass energy is not the way to accomplish this end goal.
BIOMASS BURNING IS POLLUTION
First and foremost, biomass burning isn’t green. Burning wood produces huge amounts of pollution. Especially in valleys like Missoula where temperature inversions are common, pollution from a biomass burner will be the source of numerous health ailments. Because of the air pollution and human health concerns, the Oregon Chapter of the American Lung Association, the Massachusetts Medical Society and the Florida Medical Association, have all established policies opposing large-scale biomass plants.
The reason for this medical concern is that even with the best pollution control devises, biomass energy is extremely dirty. For instance, one of the biggest biomass burners now in operation, the McNeil biomass plant in Burlington, Vermont is the number one pollution source in the state, emitting 79 classified pollutants. Biomass releases dioxins, and as much particulates as coal burning, plus carbon monoxide, nitrogen oxide, sulfur dioxide, and contributes to ozone formation. […]
BIOMASS ENERGY IS INEFFICIENT
Wood is not nearly as concentrated a heat source as coal, gas, oil, or any other fossil fuel. Most biomass energy operations are only able to capture 20-25% of the latent energy by burning wood. That means one needs to gather and burn more wood to get the same energy value as a more concentrated fuel like coal. That is not to suggest that coal is a good alternative, rather wood is a worse alternative. Especially when you consider the energy used to gather the rather dispersed source of wood and the energy costs of trucking it to a central energy plant. If the entire carbon footprint of wood is considered, biomass creates far more CO2 with far less energy output than other energy sources.
The McNeil Biomass Plant in Burlington Vermont seldom runs full time because wood, even with all the subsidies (and Vermonters made huge and repeated subsidies to the plant—not counting the “hidden subsidies” like air pollution) wood energy can’t compete with other energy sources, even in the Northeast where energy costs are among the highest in the nation. Even though the plant was also retrofitted so it could burn natural gas to increase its competitiveness with other energy sources, the plant still does not operate competitively. It generally is only used to off- set peak energy loads.
One could argue, of course, that other energy sources like coal are greatly subsidized as well, especially if all environmental costs were considered. But at the very least, all energy sources must be “standardized” so that consumers can make informed decisions about energy—and biomass energy appears to be no more green than other energy sources.
BIOMASS SANITIZES AND MINES OUR FORESTS
The dispersed nature of wood as a fuel source combined with its low energy value means any sizable energy plant must burn a lot of wood. For instance, the McNeil 50 megawatt biomass plant in Burlington, Vermont would require roughly 32,500 acres of forest each year if running at near full capacity and entirely on wood. Wood for the McNeil Plant is trucked and even shipped on trains from as far away as Massachusetts, New Hampshire, Quebec and Maine.
Biomass proponents often suggest that wood [gathered] as a consequence of forest thinning to improve “forest health” (logging a forest to improve health of a forest ecosystem is an oxymoron) will provide the fuel for plant operations. For instance, one of the assumptions of Senator Tester’s Montana Forest Jobs bill is that thinned forests will provide a ready source of biomass for energy production. But in many cases, there are limits on the economic viability of trucking wood any distance to a central energy plant. Again without huge subsidies, this simply does not make economic sense. Biomass forest harvesting is even worse for forest ecosystems than clear-cutting. Biomass energy tends to utilize the entire tree, including the bole, crown, and branches. This robs a forest of nutrients, and disrupts energy cycles.
Worse yet, such biomass removal ignores the important role of dead trees to sustain the forest ecosystems. Dead trees are not a “wasted” resource. They provide home and food for thousands of species, including 45% of all bird species in the Nation. Dead trees that fall to the ground are used by insects, small mammals, amphibians and reptiles for shelter and even potentially food. Dead trees that fall into streams are important physical components of aquatic ecosystems and provide critical habitat for many fish and other aquatic species. Removal of dead wood is mining the forest. Keep in mind that logging activities are not benign. Logging typically requires some kind of access, often roads which are a major source of sedimentation in streams, and disrupt natural subsurface water flow. Logging can disturb sensitive wildlife like grizzly bear and even elk are known to abandon locations with active logging. Logging can spread weeds. And finally since large amounts of forest carbon are actually tied up in the soils, soil disturbance from logging is especially damaging, often releasing substantial additional amounts of carbon over and above what is released up a smoke stack.
BIOMASS ENERGY USES LARGE AMOUNTS OF WATER
A large-scale biomass plant (50 MW) uses close to a million gallons of water a day for cooling. Most of that water is lost from the watershed since approximately 85% is lost as steam. Water channeled back into a river or stream typically has a pollution cost as well, including higher water temperatures that negatively impact fisheries, especially trout. Since cooling need is greatest in warm weather, removal of water from rivers occurs just when flows are lowest, and fish are most susceptible to temperature stress.
BIOMASS ENERGY SAPS FUNDS FROM OTHER TRULY GREEN ENERGY SOURCES LIKE SOLAR
Since biomass energy is eligible for state renewable portfolio standards (RPS), it has captured the bulk of funding intended to move the country away from fossil fuels. For example, in Vermont, 90% of the RPS is from “smokestack” sources—mostly biomass incineration. This pattern holds throughout many other parts of the country. Biomass energy is thus burning up funds that could and should be going into other energy programs like energy conservation, solar and insulation of buildings.
PUBLIC FORESTS WILL BE LOGGED FOR BIOMASS ENERGY
Many of the climate bills now circulating in Congress, as well as Montana Senator Jon Tester’s Montana Jobs and Wilderness bill target public forests. Some of these proposals even include roadless lands and proposed wilderness as a source for wood biomass. One federal study suggests that 368 million tons of wood could be removed from our national forests every year—of course this study did not include the ecological costs that physical removal of this much would have on forest ecosystems.
The Biomass Crop Assistance Program, or BCAP, which was quietly put into the 2008 farm bill has so far given away more than a half billion dollars in a matching payment program for businesses that cut and collect biomass from national forests and Bureau of Land Management lands. And according to a recent Washington Post story, the Obama administration has already sent $23 million to biomass energy companies, and is poised to send another half billion.
And it is not only federal forests that are in jeopardy. Many states are eying their own state forests for biomass energy. For instance, Maine recently unveiled a new plan known as the Great Maine Forest Initiative which will pay timber companies to grow trees for biomass energy.
JOB LOSSES
Ironically one of the main justifications for biomass energy is the creation of jobs, yet the wood biomass rush is having unintended consequences for other forest products industries. Companies that rely upon surplus wood chips to produce fiberboard, cabinet makers, and furniture are scrambling to find wood fiber for their products. Considering that these industries are secondary producers of products, the biomass rush could threaten more jobs than it may create.
BOTTOM LINE
Large scale wood biomass energy is neither green, nor truly economical. It is also not ecologically sustainable and jeopardizes our forest ecosystems. It is a distraction that funnels funds and attention away from other more truly worthwhile energy options, in particular, the need for a massive energy conservation program, and changes in our lifestyles that will in the end provide truly green alternatives to coal and other fossil fuels.

DOE grants moratorium on safety inspections for nuclear weapons labs
Project on Government Oversight | January 7, 2010
If your kid accidentally blew apart a building, would you give them less supervision? This hands-off approach is exactly what the Department of Energy’s National Nuclear Security Administration (NNSA) is doing by giving the contractors who manage the nation’s eight nuclear weapons sites (Los Alamos National Laboratory, Lawrence Livermore National Laboratory, Nevada Test Site, Sandia National Laboratory, Savannah River Site, Pantex, Y-12, and the Kansas City Plant) a six-month break from many regularly scheduled oversight reviews.
On December 18, 2009–two days after researchers at the Los Alamos National Laboratory (LANL) accidentally blew apart a building, causing an initial estimate of $3 million in damage–NNSA Administrator Tom D’Agostino signed a directive “placing a six-month moratorium on NNSA-initiated functional assessments, reviews, evaluations and inspections.” Project on Government Oversight (POGO) saw this directive coming, as DOE and NNSA have initiated reforms to put contractors in charge of their own oversight, “Reforming the Nuclear Security Enterprise.” POGO is not convinced that this moratorium is so temporary, and is interested to know what NNSA is going to do with all of the federal full time employees at the site offices and headquarters it no longer needs as a result of this directive.
Getting a hiatus from regular reviews are many of the areas that have had recent serious problems—security, nuclear safety, cyber security, Material Control and Accountability (MC&A), contractor assurance systems that relate to contract oversight, property accountability, and nuclear weapons quality. For example, the weaknesses with Los Alamos’s MC&A program were so significant it took NNSA more than a year and a half to resolve them. Additionally, it was NNSA, not the contractor that found that Los Alamos treated its loss of more than 67 computers merely as a property management issue, and not as a potential lapse in cyber security. Over the last few years, POGO has also discovered countless security and safety incidents at Los Alamos, Livermore National Laboratory, Pantex, and Y-12, that the contractors had not provided oversight sufficient to prevent and resolve the problems. In the past, a senior manager at Los Alamos and his sidekick went to jail when the procurement system got out of control. Now, the directive exempts Los Alamos from a procurement management review.
“It seems foolish for NNSA to abdicate its management, given the last few years of debacles at the labs,” says POGO Senior Investigator Peter Stockton. “NNSA needs to recognize its role in overseeing the labs, as that was one of the major reasons it was created.”
NNSA’s new approach to federal safety and security oversight is irresponsible—stopping it in its entirety for six months. POGO would instead like to see NNSA make a New Year’s resolution to conduct smarter, more rigorous oversight of its labs. Such a move could prevent some of the costly contractor errors that occurred in 2009, such as Los Alamos’s Plutonium Facility (PF-4) needing to stop its main operations for more than one month, once again, because of the contractor and NNSA’s inadequate oversight of its fire suppression system.

Meltdown, USA: Nuclear Drive Trumps Safety Risks and High Cost
By Art Levine, t r u t h o u t | News Analysis | January 6, 2010

The pro-nuclear Department of Energy is set this month to offer the first of nearly $20 billion in loan guarantees to a nuclear industry that hasn’t built a plant since the 1970s or raised any money to do so in years. But although the industry is seeking to cash in on global warming concerns with $100 billion in proposed loan guarantees, environmentalists, scientists and federal investigators are warning that lax oversight by the Nuclear Regulatory Commission (NRC) of the nation’s aging 104 nuclear plants has led to near-meltdowns along with other health and safety failings since Three Mile Island – including what some critics say is a flawed federal health study apparently designed to conceal cancer risks near nuclear plants.
Also See: Part II: Energy Department, NRC Back Nuclear, Ignore Industry’s Dirty Little Secrets
All that is joined by the dangers and risks posed by at least 30 tons yearly of radioactive, cancer-causing, nuclear waste produced at each 1,000 megawatt plant; projected costs of $12 billion to $25 billion for any new plants (built largely through taxpayer support).
For instance, a meltdown of the two reactors at Indian Point, dubbed “Chernobyl on the Hudson,” could quickly kill nearly 50,000 people with radiation poisoning in a 50-mile radius and cause over 500,000 cancer deaths within six years, according to research by the Union of Concerned Scientists and other experts.
“Nothing’s changed,” said Paul Gunter, director of Reactor Oversight for the Beyond Nuclear reform group, about nuclear plants. “They’re still dirty, dangerous and expensive.”
But such concerns stand in sharp contrast to a wave of positive PR about the nuclear industry as the “clean air energy” solution to global warming, driven by ads, campaign donations and lobbying – and abetted by media outlets too often willing to accept industry and Nuclear Regulatory Commission spin at face value.
Even so, there’s little reason to have confidence in the NRC’s ability to protect the public or successfully monitor the current nuclear plants, let alone any new ones. In fact, with the bulk of its funding coming from nuclear utility industry fees, the agency appears to be literally asleep at the wheel, allowing everything from near meltdowns in a Toledo plant to ignoring internal reports of rent-a-cops at vulnerable nuclear plants sleeping on the job – until the negative publicity became too overwhelming. Ultimately, the agency gave that Exelon company a mild $65,000 fine last year. Meanwhile, researchers for the Project on Government Oversight and Union of Concerned Scientists found that the utility, the Wackenhut Security Firm and the NRC all knew well before the scandal broke publicly that guards were sleeping on the job at the Peach Bottom facility in Pennsylvania.
As one researcher pointed out in 2008 testimony, “Neither Wackenhut nor Exelon nor NRC acted upon the security allegations to correct the problem.”
The NRC’s coziness with industry extends to some of its own commissioners. As its own inspector general reported, before a Bush-appointed commissioner left in mid-2007, he made decisions that could benefit financially three firms he was negotiating with for jobs – including a ruling that apparently helped loosen regulatory requirements for an emergency cooling system in a Westinghouse plant.
Obama’s latest proposed appointee to the agency isn’t necessarily any less pro-industry. As Mother Jones reported about Peter Magwood: “Both before and after his time in government, he has worked as an enthusiastic advocate for nuclear interests in the private sector-including for at least one company likely to have business before the NRC in the near future.”
Indeed, there are few limits, no matter how absurd, to how far the NRC is willing to go to cut the industry plenty of slack, no matter how dangerous to the public. Take the case of the noncombustible foam that the agency ordered nuclear plants to buy in the late 1990s as a sealant to help prevent the spread of fire from room to room in a plant. It turned out that there was a small problem with this well-meaning plan: the brand of silicone foam bought by most of the nuclear power companies turned out to be, well, combustible. So, did the NRC then promptly order the dangerous, potentially life-threatening foam removed? No, of course not: it just revised its regulations to drop the phrase and requirement of “noncombustibility” for the foam.
Paul Gunter, then with the Nuclear Information and Resource Service, found himself in the Kafkaesque position of having to argue in regulatory comments against the logical insanity of dropping the word “noncombustible” in requirements for fire-preventing foam. In bold letters, he wrote, “NRC PROPOSED ACTION INCREASES THE RISK OF A NUCLEAR ACCIDENT RESULTING FROM THE REDUCTION OF DEFENSE-IN-DEPTH OF FIRE PROTECTION SYSTEMS….” He then attempted to reason with the NRC, noting, “the material in question is designated as a fire-barrier seal.” He and other critics did not prevail, and the NRC continues to allow nuclear companies to buy combustible foam as fire prevention sealants. “The shit burns, it’s combustible and it leaves charring,” Gunter now pointed out, asking, reasonably, how it could possibly meet fire protection standards.
The NRC also uses technicalities in other ways to advance industry interests. As Beyond Nuclear and other critics point out, there’s an important reason that so little is known about the dangers of radiation for those living near nuclear plants in America: there’s very little well-designed research that has been done on the issue.
There are some exceptions: a Massachusetts Department of Public Health study in the late 1980s, though, found a 400 percent increase in leukemia for those living downwind from the Pilgrim plant, and a recent German government study found that children under five living less than five kilometers from a nuclear plant had twice the risk of contracting leukemia of those living more than five kilometers away.
Yet, one of the most influential American studies on the topic was released in 1990 by the National Cancer Institute at the behest of the NRC – and it found, by studying the overall cancer incidence of those living in surrounding counties, nuclear power plants posed no apparent radiation risk for those living in the area. Yet, while hailed by the nuclear industry and the NRC, scientific and medical critics of nuclear power had strong doubts about the study’s design and its failure to measure the impact on those living nearby.
As The New York Times reported:
But Daryl Kimball, associate director for policy of Physicians for Social Responsibility, a national organization of medical professionals concerned with nuclear war and other dangers from nuclear power, said the study ”raises more questions than it answers.”
Mr. Kimball said the study diluted the risks of exposure to radiation from nuclear plants by examining entire counties instead of areas where people were directly exposed to radiation. He cited the Fernald weapons plant near Cincinnati, where over 500,000 pounds of uranium were released into the atmosphere. This uranium may have fallen on only a small area, he said, but the study includes all the people in the surrounding counties.
Because of questions about conflict of interest and research integrity, Beyond Nuclear, among others, is asking the NRC to take a hands-off position in commissioning a new academic study. “The NRC receives about 90 percent of its funding from nuclear power reactor licensing fees,” said Cindy Folkers, radiation and health specialist with Beyond Nuclear. “As such, NRC clearly stands to gain from more reactor construction. Therefore, it should not be doing cancer studies or directly hiring people to conduct such studies. This is a flagrant conflict-of-interest and puts a scientifically rigorous, non-biased study at great risk.”
In response, a spokesperson for the NRC said the agency is using a peer-review panel of experts drawn from the National Cancer Institute and other agencies to oversee the research. “The panel will provide comments on the proposed methodology before the study is done, and it will review the study’s results, ensuring a scientifically sound project that uses the latest available data,” spokesman Scott Burnell said in an emailed response.
Yet, despite all these problems, a seemingly benign “solution for global warming” – nuclear energy – has boundless, if simplistic, appeal, even if it could take years to build and threatens public health and safety, while undermining genuine renewable energy with billions devoted to nuclear bailouts.
Still, the pro-nuclear pitch is especially welcomed by media outlets when it advances the seemingly fresh story line of environmentalists embracing nuclear power, as delivered by the likes of ex-Greenpeace activist Patrick Moore, whose financial ties to a Nuclear Energy Institute front group are rarely disclosed.
For instance, as the Center for Media and Democracy has noted, Moore has recently placed op-eds extolling nuclear power in such reputable publications as The Philadelphia Inquirer, while being paid by the front organization The Clean and Safe Energy Industry Coalition (CASE). This flack outfit, nominally headed by former Gov. and EPA Director Christine Todd Whitman, was actually established by the PR firm Hill and Knowlton at the behest of the Nuclear Energy Institute.
Moore recently outlined the selling points that the nuclear industry – and its allies in Congress – are promoting to sprinkle eco-friendly fairy dust around the grim nuclear industry that Wall Street and private investors won’t touch:
Old Foes Welcome Clean Fuel Rising demand for emission-free energy is spurring a nuclear rebirth.
By Patrick Moore
Nuclear energy, a prime source of electricity for Pennsylvania, is finally getting the respect it deserves.
It’s not hard to see why: America’s power needs continue to grow, and meeting them without harming the environment calls for every available nonpolluting energy source.
Nuclear energy is the most dependable and cost-effective such option.
It isn’t the only solution, of course. Wind, geothermal, and other renewable energy sources will likely become a bigger part of Pennsylvania’s energy portfolio, and America’s. But nuclear energy will be expected to shoulder the biggest load.
Because nuclear energy is virtually emissions-free, America’s 104 nuclear reactors already account for nearly 75 percent of the country’s clean energy, and 93 percent of Pennsylvania’s.
Nuclear energy has maintained a strong record of safety, reliability, and efficiency for decades, and Americans increasingly appreciate its environmental and economic benefits. A recent Gallup poll showed that 59 percent of Americans support using nuclear energy to meet the country’s energy needs. Support is even higher in Pennsylvania, reaching 82 percent of residents polled last year for the Pennsylvania Energy Alliance.
Unfortunately for Moore and fellow spinmeisters, nuclear energy isn’t the clean, harmless, renewable resource it’s portrayed here and by nuclear propaganda. The “clean air energy” meme comes complete with lovely images of the nuclear icon surrounded by leaves and flowers, or as in the Nuclear Energy Institute’s web site, features a happy family cavorting in a flowery green field. In fact, as Greenpeace, among others, has pointed out:
Let’s be blunt here. This isn’t just misleading. This isn’t just misinformation. This is a lie.
Nuclear energy is not clean energy. One need only look at the environmental destruction caused by uranium mining. In his book ‘Wollaston: People Resisting Genocide’, Miles Goldstick details the damage brought to the lives of the people living around the uranium mines in Canada’s Saskatchewan province. The accumulation of radioactive isotopes in edible plants. The lead, arsenic, uranium and radium found downstream from the mines. The spills that J.A. Keily, then Vice President of Production and Engineering for Gulf Minerals Rabbit Lake, described in 1980 as “probably too numerous to count.”
These are stories found wherever uranium mining takes place. The ruined lives, the contamination, the cover-ups, and the deception. And that’s before we even consider what happens to the waste produced by generating nuclear energy.
[…] Most critically, nuclear power-generated electricity is so much more expensive for consumers and businesses to use than renewables and conservation combined. That means that a new 1,000 megawatt nuclear plant would rob electricity users of $256 million they could have used for everything from making individual purchases to hiring more workers, according to John A. “Skip” Laitner, the director of economic and social analysis for the American Council for an Energy-Efficient Economy (ACEEE). “Energy-related sectors don’t support anywhere near the jobs that other sectors of the economy do,” he pointed out. “So going the nuclear route is a net loss to the economy” – except, of course, for the extra spending on hospitals and doctors to treat those residents near nuclear plants and mining facilities who develop cancers or birth defects.
Moreover, as Dr. Helen Caldicott and other experts have noted, “Large amounts of the now-banned chlorofluorocarbon gas (CFC) are emitted during the enrichment of uranium. CFC gas is not only 10,000 to 20,000 times more efficient as an atmospheric heat trapper (‘greenhouse gas’) than CO2, but it is a classic ‘pollutant’ and a potent destroyer of the ozone layer.”
In fact, it is the mining of uranium, followed by its “enrichment” – using carbon-polluting, complex ultracentrifuges or gaseous diffusion processes – to separate it into fissionable U-235 isotopes that are the dark truths about nuclear power hidden among the greenery of the industry’s propaganda. As Greenpeace pointed out:
Nuclear fuel production – the mining, milling and enriching of uranium – is one of the nuclear industry’s dirty secrets. Very little attention is paid to it by industry propagandists and pro-nuclear politicians and for very good reason. It’s dirty, dangerous, incredibly damaging to the environment and endangers the health of those people unfortunate enough to live close to uranium mines.
To hear some supporters of nuclear energy talk, you’d think the whole process of generating electricity begins with the throwing of a reactor’s “on” switch. But there’s a long story before we even get that far. It’s also a long, sad story that often goes untold in the wider media.
Pick any uranium mine around the world and it will invariably be surrounded by stories of pollution, contamination and the exploitation of local communities. Niger, Namibia, Brazil, Canada, Kazakhstan.
And Australia. The country’s “Environment Minister Peter Garrett has formally approved the new Four Mile uranium mine in South Australia, saying it poses no environmental risks.”
The article goes on to chronicle ten major spills of radioactive materials in Australia in the last decade at that mine.
In fact, the true dangers of this uranium mining and enrichment are becoming tragically and increasingly apparent – and will doubtless spread as more plants could get built worldwide. All this adds to the ongoing, unsolved problem of finding a safe repository in the United States for radioactive waste from nuclear plants still kept at their sites, now that long-delayed plans to use Yucca Mountain in Nevada have finally fallen apart.
As Greenpeace asked, “Delays in the construction and opening of Yucca Mountain have been seen as a large obstacle to the expansion of nuclear power in the US. With no viable plan for the safe disposal of nuclear waste in the country how can the go ahead for further nuclear reactors be given?”
Moreover, whether in Native-American reservations here or in Niger villages abroad, indigenous, impoverished people live near or work in uranium mines to supply nuclear plants, and suffer the consequences in cancers, birth defects and leukemia.
It’s a cruel irony that the poisonous levels of radiation in the uranium waste found in Niger villages comes from mining by the French nuclear company AREVA; their trouble-plagued plants and behind-schedule production are somehow seen as a role model for America’s proposed next generation of nuclear plants – and slated to be supported by US taxpayer-backed loan guarantees.
As Greenpeace asked recently, in awarding the 2009 “Blind Eye” Award:
For many of us, some of the electricity we use every day comes from nuclear power stations. Those reactors are fuelled with uranium. Do you know where that uranium comes from?
Does it come from Namibia where uranium mining has made the traditional lifestyles of the Topnaar Nama people ‘impossible to maintain’. Does it come from Caetite in Brazil where the drinking water has been contaminated with uranium? Does it come from Australia or Canada where there native peoples’ ways of life are threatened? Does it come from Niger whose streets where children play are contaminated with radiation?
Uranium Weapons, Low-Level Radiation and Deformed Babies
by Paul Zimmerman | Global Research | January 1, 2010
A dramatic increase in the number of babies born with birth defects was recently reported by doctors working in Falluja, Iraq [1]. One of the proposed causes for this alarming situation is radiation exposure to the population produced by uranium weapons. The international radiation protection community dismisses this explanation as completely unreasonable because (1) the radiation dose to the population of Iraq was too low, and (2) no evidence of birth defects was reported among offspring born to survivors of the atomic bombings of Hiroshima and Nagasaki. This so-called scientific explanation is deeply disturbing, for it is out of touch with the current knowledge base. Abundant evidence exists which clearly demonstrates that birth defects are being induced by levels of radiation in the environment deemed safe by the radiation protection community. In light of this knowledge, uranium contamination cannot be summarily dismissed as a hazard to the unborn.
The destruction of the nuclear reactor at Chernobyl produced a different type of radiation exposure from that portrayed for the atomic bomb. In Japan, victims were exposed to an instantaneous flash of gamma radiation and neutrons delivered from outside their bodies. In contrast, the Chernobyl accident scattered microscopic radioactive particles from the reactor’s core throughout Europe which was then inhaled and ingested by the populace. In this situation, those contaminated began receiving ongoing, low-dose exposure internally. According to the current theory of radiation effects embraced by the radiation protection community, there is no qualitative difference in the two types of exposure. What matters is the total amount of energy delivered to the body. Thus, the health effects experienced by the survivors of Hiroshima and Nagasaki can be considered to be representative of the health effects produced from any type of radiation exposure. In the case of birth defects, this assumption has been proven wrong. As a result of the external exposure in Japan, there was no increase in the incidence of birth defects among children whose parents were exposed to the bombings [2]. In contrast, radiation-induced birth defects have been documented in populations receiving low doses of internal contamination. In light of this contradiction, it’s obvious that the accepted theory of radiation effects is in error and needs to be corrected. The information which follows will demonstrate the hazard to the unborn produced by radioactive material vented into the environment.
1. In the book Chernobyl: 20 Years On, a chapter is devoted to discussing the birth defects in children who, while gestating in the wombs of their mothers, were exposed to radioactivity released by the Chernobyl reactor [3]. The author provides an overview of dozens of studies which confirm that low levels of radiation present in many areas of Europe after Chernobyl were responsible for a wide variety of birth defects. These birth defects occurred where radiation exposure was judged by the radiation protection agencies to be too low to warrant concern. Fifteen studies were cited which demonstrated an increase in the incidence of a wide variety of congenital malformations. Other studies cited confirmed increases in the rate of stillbirths, infant deaths, spontaneous abortions, and low birthweight babies. An elevated incidence of Down’s syndrome was also documented. In addition, an excess of a variety of other health defects were detected which included mental retardation and other mental disorders, diseases of the respiratory and circulatory systems, and asthma.
In a separate chapter of the same book, Alexey Yablokov of the Russian Academy of Sciences provided a review of the extensive body of research conducted after Chernobyl. Regarding studies on birth defects, he cited an increased frequency of a number of congenital malformations which included cleft lip and/or palate (“hare lip”), doubling of the kidneys, polydactyly (extra fingers or toes), anomalies in the development of nervous and blood systems, amelia (limb reduction defects), anencephaly (defective development of the brain), spina bifida (incomplete closure of the spinal column), Down’s syndrome, abnormal openings in the esophagus and anus, and multiple malformations occurring simultaneously [4].
2. The wide range of birth defects produced by the Chernobyl accident cannot be accounted for by the data collected from the survivors of Hiroshima and Nagasaki. This is one compelling thread of evidence that something is amiss in the current field of radiation protection. But there is a further problem. The proposed threshold dose of radiation capable of interfering with the development of a fetus, again based on the research from Japan, is between fifty and one hundred times greater than what the radiation protection community insists was the typical exposure in the areas of Europe where the elevated frequency of birth defects was documented. How are we to make sense of these contradictions? Chromosome studies conducted in the contaminated regions provide the answer.
In individuals exposed to ionizing radiation, peripheral lymphocytes, those lymphocytes which circulate in the blood, have an elevated occurrence of certain types of misshapen chromosomes [3,5]. Of particular interest are dicentric chromosomes which are produced when radiation breaks both strands of the DNA double helix in two neighboring chromosomes and the genetic material is then misrepaired. An increase in the relative frequency of these aberrantly shaped structures serve as a biological indicator of radiation exposure which is immune to lies and political propaganda. More specifically, the increased rate of these aberrations is proportional to the dose of radiation received. Thus, their frequency can be used to determine the true level of exposure in contaminated individuals. Studies of this type were conducted in Europe subsequent to the Chernobyl accident [3]. These studies demonstrated that the official dose estimates published by the radiation protection agencies were woefully in error, greatly underestimating the true level of exposure of people throughout Europe. This discrepancy casts further doubt on the scientific integrity of those organizations who are supposedly protecting the world from radioactive pollution. When combining the studies of chromosome aberrations with the studies of birth defects, the science speaks for itself: the population in many areas of Europe received much higher doses from Chernobyl than claimed and birth defects were induced by much smaller doses than suggested by current radiation protection science.
3. As the clouds of fallout from Chernobyl wafted around the planet, governments broadcast reassurances to their anxious citizens that there was no cause for concern, that doses to the public would be too low to produce detrimental health effects. Politically motivated, this advice was medically ill-conceived. What became evident after the accident was that children who received exposure to Chernobyl fallout, while still in the wombs of their mothers, experienced an elevated risk of developing leukemia by the time of their first birthday [6,7]. Relevant to this discussion is the fact that a gene mutation occurring in utero is one cause of infant leukemia [8,9].) In countries where unimpeachable data was collected for levels of fallout deposited in the environment, doses to the population, and the incidence of childhood leukemia, an unmistakable, uniform trend emerged: the studied population of children born during the 18-month period following the accident suffered increased rates of leukemia in their first year of life compared to children born prior to the accident or to those born subsequent to the accident after the level of possible maternal contamination had sufficiently diminished. This was confirmed in five separate studies conducted independently of one another: in Greece [9], Germany [10], Scotland [11], the United States [12], and Wales [13]. Again here is evidence that defects are being induced in fetuses that we are told by the radiation protection community are not possible. According to the European Committee on Radiation Risk (ECRR), these results provide unequivocal evidence that the risk model of the International Commission on Radiological Protection (ICRP) for infant leukemia is in error by a factor of between 100-fold and 2000-fold, the latter figure allowing for a continued excess incidence of leukemia as the population of children studied continues to age [6].
4. Other types of chromosome studies have been performed which demonstrate that radiation in the environment is producing damage to DNA that is being passed on to offspring. Minisatellites are identical short segments of DNA that repeat over and over again in a long array along a chromosome. These stretches of DNA do not code for the formation of any protein. What distinguishes these minisatellites is that they acquire spontaneous repeats through mutation at a known rate, which is 1,000 times higher than normal protein-coding genes. Dr. Yuri Dubrova, currently at the University of Leicester, first realized that these stretches of DNA could be used to detect radiation-induced genetic mutations by showing that their known rate of mutation had increased subsequent to exposure. Dubrova and his colleagues studied the rate of minisatellite mutations in families that had lived in the heavily polluted rural areas of the Mogilev district of Belarus after the Chernobyl meltdown [14]. They found the frequency of mutations being passed on by males to their descendants was nearly twice as high in the exposed families compared to the control group families. Among those exposed, the mutation rate was significantly greater in families with a higher parental dose. This finding was consistent with the hypothesis that radiation had induced mutations in the the reproductive germ cells of parents and then transmitted to their offspring. This was the first conclusive proof that radiation produced inheritable mutations in humans.
Minisatellite DNA testing has also been performed on the children of Chernobyl “liquidators” i.e., those people who participated in post-accident cleanup operations. When the offspring of liquidators born after the accident were compared to their siblings born prior to the accident, a sevenfold increase in genetic damage was observed [15,16]. As reported by the ECRR, “for the loci measured, this finding defined an error of between 700-fold and 2,000-fold in the ICRP model for heritable genetic damage” [6]. The ECRR made this further observation: “It is remarkable that studies of the children of those exposed to external radiation at Hiroshima show little or no such effect, suggesting a fundamental difference in mechanism between the exposures [17]. The most likely difference is that it was the internal exposure to the Chernobyl liquidators that caused the effects”.
5. In November 2009, Joseph Mangano of the Radiation and Public Health Project published a study of newborn hypothyroidism near the Indian Point nuclear reactors in Buchanan, New York [13]. Hypothyroidism is a disease characterized by an insufficient production of the hormone thyroxine. One cause of the disease is exposure to radioactive iodine which selectively destroys cells in the thyroid gland. Currently, the only environmental source of radioactive iodine is emissions from nuclear power plants. According to Mangano, four counties in New York state flank Indian Point and nearly all the residents of these counties live within 20 miles of the reactor complex. During the period 1997 to 2007, the rate of newborn hypothyroidism in the combined four-county population was 92.4% greater, or nearly double, the U.S. rate. The rate in each of the four counties separately was above the U.S. rate, and in two of the counties, the rate was more than double the national rate. In the period 2005-2007, the four county rate was 151.4% above the national rate. These finding were consistent with the fact that the local rate of thyroid cancer is 66% greater than the U.S. rate [14].
Mangano’s study raises important questions regarding our common welfare. We live with assurances by government and industry that nuclear reactors are operating within guidelines sponsored by the radiation protection agencies. What radiation they emit are dismissed as too low to warrant concern. An yet, babies born to mothers living in proximity to Indian Point are suffering an increased rate of hypothyroidism. Either the reactor complex is emitting more radiation than publicly known, or once again, there is an error in the safety standards published by the radiation protection community.
6. Are weapons containing depleted uranium a cause for concern for producing birth defects? Given that uranium inside the human body targets the reproductive system, the elevated rate of birth defects in Iraq strongly suggests that DU exposure is involved. In experimental animals exposed to uranium compounds, uranium has been found to accumulate in the testes [20]. Among Gulf War veterans wounded by DU shrapnel, elevated levels of uranium have been found in their semen [21]. In light of this discovery, the Royal Society cautions that this raises “the possibility of adverse effects on the sperm from either the alpha-particles emanating from DU, chemical effects of uranium on the genetic material or the chemical toxicity of uranium [21].” In experiments on female rats, uranium was found to cross the placenta and become concentrated in the tissues of the fetus [20,21,22]. When DU pellets were implanted into pregnant female rats, a direct relation was observed between the amount of contamination in the mother and the amount of contamination in the placenta and the fetus [23,24]. Most importantly, once dissolved within the body, uranium’s primary chemical form is the uranyl ion UO2++. This form of uranium has an affinity for DNA and binds strongly to it [25]. This fact alone is should be sufficient to halt the scattering of DU aerosols amidst populations. Internalized uranium targets human genetic material! Needless to say, this fact is totally ignored by the International Commission on Radiological Protection and related organizations when determining safe levels of exposure to uranium and assessing the risk posed by uranium for inducing birth defects.
7. In infants, hydrocephalus is a condition characterized by increased head size and atrophy of the brain. The frequency of this birth defect has increased dramatically in Iraq since the first Gulf War [26]. A small and admittedly incomplete study conducted in the United States lends credence to the hypothesis that DU exposure is the causative agent [26]. Rural and sparsely populated Socorro County is located downwind of a DU-weapons testing site, the Terminal Effects Research and Analysis division of the New Mexico Institute of Mining and Technology. On average, 250 births occur yearly in the county. An investigation by a community activist revealed that between 1984 and 1986, five infants were born with hydrocephalus. (The normal rate of hydrocephalus is one case in every 500 live births). According to the demonstrably incomplete State of New Mexico’s passive birth defects registry, between 1984 and 1988, 19 infants were born statewide with the condition, three of these within Socorro county. Regardless of which accounting is correct, the results are disturbing given that Socorro contains less than 1% of the state’s population.
8. To conclude, the current dogma regarding radiation effects cannot account for the increase in genetic malformations in populations exposed internally to low levels of radiation. Something is deeply wrong with the current science of radiation safety. Given this, statements by the radiation protection community regarding the impossibility that low levels of uranium can cause birth defects are suspect. Numerous studies demonstrate that uranium produces a wide range of birth defects in experimental animals [20,26]. Further, numerous in vitro and in vivo studies conducted in the last twenty years have proven that uranium is genotoxic (capable of damaging DNA), cytotoxic (poisonous to cells), and mutagenic (capable of inducing mutations) [27]. These effects are produced either by uranium’s radioactivity or its chemistry or a synergistic interaction between the two. These findings lend plausibility to the idea that the observed increased incidence of deformed babies in Iraq is related to depleted uranium munitions [26].

Chernobyl Exclusion Zone Radioactive Longer Than Expected
- By Alexis Madrigal
- December 15, 2009

SAN FRANCISCO — Chernobyl, the worst nuclear accident in history, created an inadvertent laboratory to study the impacts of radiation — and more than twenty years later, the site still holds surprises.
Reinhabiting the large dead zone around the accident site may have to wait longer than expected. Radioactive cesium isn’t disappearing from the environment as quickly as predicted, according to new research presented here Monday at the meeting of the American Geophysical Union. Cesium 137’s half-life — the time it takes for half of a given amount of material to decay — is 30 years, but the amount of cesium in soil near Chernobyl isn’t decreasing nearly that fast. And scientists don’t know why.
It stands to reason that at some point the Ukrainian government would like to be able to use that land again, but the scientists have calculated that what they call cesium’s “ecological half-life” — the time for half the cesium to disappear from the local environment — is between 180 and 320 years.
“Normally you’d say that every 30 years, it’s half as bad as it was. But it’s not,” said Tim Jannick, nuclear scientist at Savannah River National Laboratory and a collaborator on the work. “It’s going to be longer before they repopulate the area.”
In 1986, after the Chernobyl accident, a series of test sites were established along paths that scientists expected the fallout to take. Soil samples were taken at different depths to gauge how the radioactive isotopes of strontium, cesium and plutonium migrated in the ground. They’ve been taking these measurements for more than 20 years, providing a unique experiment in the long-term environmental repercussions of a near worst-case nuclear accident.
In some ways, Chernobyl is easier to understand than DOE sites like Hanford, which have been contaminated by long-term processes. With Chernobyl, said Boris Faybishenko, a nuclear remediation expert at Lawrence Berkeley National Laboratory, we have a definite date at which the contamination began and a series of measurements carried out from that time to today.
“I have been involved in Chernobyl studies for many years and this particular study could be of great importance to many [Department of Energy] researchers,” said Faybishenko.
The results of this study came as a surprise. Scientists expected the ecological half-lives of radioactive isotopes to be shorter than their physical half-life as natural dispersion helped reduce the amount of material in any given soil sample. For strontium, that idea has held up. But for cesium the the opposite appears to be true.
The physical properties of cesium haven’t changed, so scientists think there must be an environmental explanation. It could be that new cesium is blowing over the soil sites from closer to the Chernobyl site. Or perhaps cesium is migrating up through the soil from deeper in the ground. Jannik hopes more research will uncover the truth.
“There are a lot of unknowns that are probably causing this phenomenon,” he said.
Beyond the societal impacts of the study, the work also emphasizes the uncertainties associated with radioactive contamination. Thankfully, Chernobyl-scale accidents have been rare, but that also means there is a paucity of places to study how radioactive contamination really behaves in the wild.
“The data from Chernobyl can be used for validating models,” said Faybishenko. “This is the most value that we can gain from it.”
