Low Dose Radiation Evades Cancer Cells’ Protective ‘Radar’

ScienceDaily
October 6, 2004

A new study shows that lower doses of radiation elude a damage detection “radar” in DNA and actually kill more cancer cells than high-dose radiation. With these findings, scientists believe they can design therapy to dismantle this “radar” sensor allowing more radiation to evade detection and destroy even greater numbers of cancer cells.

Researchers at the Johns Hopkins Kimmel Cancer Center tested the low-dose radiation strategy on cultured prostate and colon cancer cell lines and found that it killed up to twice as many cells as high-dose radiation. The extra lethality of the low-dose regimen was found to result from suppression of a protein, called ATM* which works like a radar to detect DNA damage and begin repair.

Theodore DeWeese, M.D., who led the study, speculates that cells hit with small amounts of radiation fail to switch on the ATM radar, which prevents an error-prone repair process. DeWeese, who will present his evidence at the annual meeting of the American Society for Therapeutic Radiology and Oncology on October 5 in Atlanta, explains. “DNA repair is not foolproof – it can lead to mistakes or mutations that are passed down to other generations of cells,” explains DeWeese, chairman of the Department of Radiation Oncology and Molecular Radiation Sciences at Johns Hopkins. “A dead cell is better than a mutant cell, so if the damage is mild, cells die instead of risking repair.”

Higher doses of radiation cause extreme DNA damage and widespread cell death, so the ATM damage sensor is activated to preserve as many cells as possible, protecting, ironically, the cancer cells under target for destruction by the radiation. While the low-dose regimen works in cultured cells, it has not proved successful in humans. This has lead to effort by Hopkins scientists to study ways to use viruses that can deliver ATM-blocking drugs to the cells. Tests in animals are expected to begin soon.

In the current study, colon and prostate cancer cells lines were treated with either high levels of radiation or small amounts spread over many days. Low-level radiation is approximately 10 times more powerful than normal exposure, while high doses are 1,000 times stronger. Approximately 35 percent of colon cancer cells survived low-dose radiation as compared to 60 percent receiving high-dose. In prostate cancer cell lines, half of the cells survived low-dose radiation, while 65 percent remained in higher doses.
In the low-dose group, ATM activation was reduced by 40 to 50 percent.

The researchers proved ATM inactivation was the culprit since low-dose irradiated cells fared better after ATM was reactivated with chloroqine, best known as a treatment for malaria.
“Tricking cancer cells into ignoring the damage signals that appear on its radar could succeed in making radiation more effective in wiping out the disease,” says DeWeese.
This research was funded by the National Cancer Institute.

Research participants from Johns Hopkins include Spencer Collis, Julie Schwaninger, Alfred Ntambi, Thomas Keller, Larry Dillehay, and William Nelson.

Aldyen Donnelly: Carbon taxes and what they mean for Canada

Please note that the wide-ranging exemptions that were embedded in France’s carbon tax proposal have also always existed and continue to exist in Swedish, Danish, Norwegian and Dutch carbon/CO2 tax laws. Germany, on the other hand, does not, nor has it ever, had a carbon or CO2 tax. These other nations do not have tax fairness laws comparable to the provisions in the French constitution in place.

Generally, GHGs arising from the combustion of fossil fuels in power production, petroleum refineries, aluminum smelters, cement plants and industrial chemical plants are and have always been carbon/CO2 tax exempt under most European tax systems.  Refineries, aluminum smelters, cement and chemical plants also have received free CO2 allowance allocations equal to forecast "business as usual" GHGs through 2012. This is true even for, say, BP, whose European ETS-covered operations realized a 24% growth in GHG emissions between 2005 and the end of 2008. 

It remains curious to me that Canadian carbon/CO2 tax proponents often refer to European carbon/CO2 tax models as "successful" but have never proposed or discussed the range of tax exemptions that typify the EU tax models. Of course, the rationale for the power sector and industrial carbon/CO2 tax exemptions is the prevention of job losses.

The important questions that Canadian CO2 tax and cap and trade proponents have avoided addressing to date include:

  • If Canada imposed CO2 taxes on Canadian sectors that are CO2 tax exempt in Europe and elsewhere, how does the government of Canada protect Canadian export market shares from lower cost (untaxed), more GHG-intensive European petroleum, aluminum, cement and chemical exports?
  • If Canada shorts the free allocation of Canadian GHG quota to Canadian sectors that receive free GHG/CO2 quota allocations equal to their "business as usual" GHG forecasts, how does the government of Canada protect Canadian export market shares from lower cost (uncapped), more GHG-intensive European petroleum, aluminum, cement and chemical exports?
  • European, Japanese and US governments have reserved the right to impose GHG tariffs on imports from Canada if Canada fails to cut national GHGs 20% below 2006 levels by 2020. If Canada gives these sectors the GHG/CO2 "pass" that they currently receive under the European ETS and, in some sectors, under the proposed US Senate and House climate change bills, how does Canada achieve our national GHG reduction target?

The Answer?

Product Standards. Canada’s ultra low sulphur diesel regulation is a product standard. The government neither sets prices, nor selects the technologies the market will employ to comply with new product standards. 

A product standard regulates carbon content or supply chain GHG emissions at the first point of distribution of the regulated products, Canada should implement a series of GHG or carbon product standards that:

  • Are at least as stringent as the European CO2 "benchmarks" for benchmarked sectors. The EU has developed emission benchmarks to determine best practices for "trade sensitive" sectors.  At this time, EU member states propose to freely allocate CO2 quota up to the benchmark emission intensity rates for EU ETS covered facilities for the post-2012 control periods. The benchmarked sectors are: aluminum, cement, ceramics, chemicals, glass, gypsum, iron and steel, iron ore, lime, mineral wool, non-ferrous metals except aluminum, pulp and paper, oil refineries. 
  • Could reasonably ensure Canadian achievement of the 20% reduction target from 2006 levels by 2020. Most Canadian facilities in the EU benchmarked sectors discharge lower GHGs (absolutely and per unit of output) than the current draft EU benchmarks. Canada could contemplate initial product standards for these sectors that are technically more stringent than the EU benchmarks.
  • For the electricity and biofuels sectors, combine the attributes of the existing US Renewable Fuel Standard and proposed US Renewable Electricity and Electricity Efficiency Standards into a single, more flexible Canadian Renewable Energy Standard.

With these product standards in place and our ability to prove at WTO, NAFTA and in US courts that our product standards are comparable in terms of environmental outcomes as the combination of regulations and GHG/CO2 quota allocations that are in place or proposed in Europe and the US, Canada should be able to successfully challenge the protectionist elements of the EU and US tax and cap and trade regimes.

Our ability to win any such trade dispute will rely, first, on our implementation of a Canadian facility-level emission reporting regulation that WTO, NAFTA and US courts would agree are "comparable" to section 40 of the US Code of Federal Regulations, part 75. This does not mean we have to implement reporting regulations that are identical to the highly invasive and administratively costly US emission reporting regulations.  But we do need to implement reporting regulations that are significantly more stringent than those that are in place federally or proposed by any Canadian province to date. 

As long as Canada fails to implement "comparable" (under WTO’s definition of "comparable", not the US definition) facility level reporting regulations, the EU, Japan and the US will maintain that Canada’s national GHG inventory claims cannot be verified. The WTO has in the past and will in the future uphold EU, Japanese and US GHG tariffs on our exports as long as the US can successfully make that case.

No investor likes to commit to a sector that can reasonably be forecast to be embroiled in a trade dispute in the near or medium term. Therefore, Canada must consider implementing new emission (pollutants and GHGs, not just GHG) reporting regulations as well as the key product standards as soon as possible, with the objective of having the regulations fully developed before the US Congress votes on a US climate change bill. 

Among the product standards, the Renewable Energy Standard is top priority.  Canada should implement the Canadian Renewable Energy Standard as soon as possible to demonstrate that we have equivalent-to-existing-US-and-EU renewable energy and fuel standards in place. Our goal should be to put this standard in place, by Order in Council, along with the new facility-level GHG reporting rules, between March 31 and July 31, 2010.

Canada should completely develop the other product standards (starting with reference to the EU benchmark studies and refining these standards in consultation with Canadian industry) including completing public consultation, by the July 31 deadline.

The other product standards can include clauses stipulating that these standards will not come into full effect unless/until the government of Canada finds that the US has implemented "comparable" standards. 

This approach positions Canada to provide the US with early warning that any highly protectionist US GHG quota allocation and trading scheme will be challenged by Canada, and also to communicate our view that product standards are more efficient than quota-based supply management for energy, building product and food markets. Canada’s move should cause a new debate to emerge in the US—which would be in Canada’s interest. 

This approach increases the odds that both Canada and the US will drop quota allocation and trading and shift to product standards, creating a more positive market signal.

Please note that credit trading and banking is a key element in all existing and proposed EU, US and Japanese product standards. It is not necessary to create, auction or allocation emission quotas to spawn a vibrant and disciplined secondary market for environmental attributes. Each of our product standards should allow for over-compliance credit banking and trading, and credit trading across sectoral boundaries.

Beyond these regulations, Canada also has to incorporate a new Class 27 Capital Cost Allowance regulation in Schedule II of the Corporate Income Tax Act, which new Class 27 regulation will focus on providing incentives for EXISTING plant operators to invest in GHG and pollution reduction measures. 

One year depreciation (same year "expensing of capital expenditures", in US tax lingo) is standard for investments that measure, control or reduce regulated emissions in the UK, EU and US at this time. 

Canada cannot attract the necessary new capital investment unless our tax act at least matches the one year tax deferral that is already available to investors in the UK, Europe and the US. The government of Canada should consider upping the ante by allowing entities that qualify for accelerated depreciation under the new Class 27 to bank (but not trade) CCA credits for up to 10 years.

I am not recommending that Class 27 credits become flow-through credits. I think the credits should not be severable from the equipment installations that qualified for accelerated depreciation. But the credit banking provision puts pressure on new technology adopters to become profitable in their Canadian operations—if they are not already—within 10 years.

I had hoped to draft at least two strawdog product standards and a new draft Class 27 regulation for illustration purposes by today, but have been unable to do so. I do anticipate, however, that I will be able to complete the two samples by the end of next week for consideration and criticism.

Special Note to Provinces About Green Bonds: Don’t Do It

Only the federal government can implement the Class 27 recommendation. Either the provinces or the federal government can implement the key product standards, but I do recommend these as federal initiatives. Given the potential for federal product standards, provinces will all consider additional measures to increase regional economic development opportunities.

Some provinces are considering other measures, such as issuing green bonds to raise financing for new green technology projects. With respect, I wish to recommend an alternative to that proposal.

Given current provincial deficit levels and the likelihood that interest rates will increase in the near term, provinces should not consider raising net debt (other than to retire existing, higher interest rate-bearing debt).

Under US federal tax law, interest income earned by private entities that lend capital in the form of debt to electric utilities and other key infrastructure projects is corporate income tax exempt, within some limits. I strongly recommend that provinces consider amending provincial tax law to incorporate income tax exemptions for interest income earned from loans to projects that meet certain environmental criteria. This approach should achieve the same objective as "green bonds", but mobilize private sector capital markets without increasing government deficit and debt levels.

Wikipedia meets its own climategate

Tom Bethell
American Spectator
December 30, 2009

Jimmy Wales, the founder of Wikipedia, had an   article in yesterday’s Wall Street Journal drawing attention to the rise of “online hostility” and the “degeneration of online civility.” He (and coauthor Andrea Weckerle) suggested ways in which we can “prevent the worst among us from silencing the best among us.”

I agree with just about everything that they say. But there is one problem that Mr. Wales does not go near. That is the use of Wikipedia itself to inflame the political debate by permitting activists to rewrite the contributions of others. All by itself, that surely is a contributor to online incivility.

The issue that I am particularly thinking about is “climate change” — or global warming as it was once called (until the globe stopped warming, about a decade ago). Recently the Financial Post in Canada published an article by Lawrence Solomon, with this remarkable headline:

How Wikipedia’s green doctor rewrote 5,428 climate articles.

Solomon draws attention to the online labors of one William M. Connolley, a Green Party activist and software engineer in Britain. Starting in February 2003, Connolley set to work on the Wikipedia site.  I continue with a two-paragraph direct quote from Mr. Solomon’s article:

[Connolley] 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 [of climatologist activists]. 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 [of activists] 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.

Online replies to this article included the following, appearing about 24 hours after Solomon’s article went on line:

Recently, the Wikipedia Arbitration Committee determined that “William M. Connolley has, on a number of occasions misused his administrator tools by acting while involved” and, as a consequence, “William M. Connolley’s administrative privileges are revoked.”

[Link: en.wikipedia.org/…/Abd-William_M._Connolley]

But three days later, on December 23, a follow-up article by Solomon said this:

How do Connolley and his co-conspirators exercise control? Take Wikipedia’s page for Medieval Warm Period, as an example. In the three days following my column’s appearance, this page alone was changed some 50 times in battles between Connolley’s crew and those who want a fair presentation of history.

So he is still at it, apparently. Connolley has for years been involved with a website called RealClimate.org. It broadcasts the views of a group of warmist ideologues, otherwise known as “working climate scientists.”  (Among them is Penn State’s Michael Mann, the inventor of the “hockey stick.”) My guess is that even if Connolley’s Wiki privileges have been revoked, his RealClimate allies continue to labor on his behalf.

The interesting paragraph below comes from Connolley’s own Wiki entry, and I suppose was written by him:

His work was also the subject of hearings by Wikipedia’s arbitration committee after a complaint was filed claiming that Connolley was pushing his own point of view in an article by removing material with opposing viewpoints. A “humiliating one-revert-a-day” editing restriction was imposed on Connolley, and he told The New Yorker that Wikipedia “gives no privilege to those who know what they’re talking about.” The restriction was later revoked, and Connolley served as a Wikipedia administrator from January 2006. [The New Yorker article was by Stacy Schiff, July 31, 2006]

It is not surprising that Connolley should think that he knows what he is talking about and that he should be “privileged.” The question is: How does Wikipedia decide between him and his allies and those who say that Connolley et al. do not know what they are talking about?

One is tempted to reply: By looking at the science. But here is an important and little-noted point. The scientific problem posed by measuring manmade global warming, if such warming really exists, is huge. There is no more complex field of science. That is because so many areas of expertise are involved — everything from the temperature effects of oceans and of cloud cover, to the study of ice cores, to the spacing of tree rings, to the proper placement of thermometers. (How many should there be in Siberia, how close should they be to New York City? and so on.)

Faced with the complexity of the way these variables interact — and I could have mentioned half a dozen more — the true scientist, at least initially, finds it difficult to be certain about the outcome. Politicians, or politicized scientists, then seized their opportunity.  Ideologues like Connolley and politicians like Al Gore filled the vacuum. Armed with world-saving missionary zeal, they milked the prestige of science to suit their own political advantage.

In so complex a field, the skeptics needed time to recover their more detached sense of what is really going on with the weather. So the warmists enjoyed a head start thanks to their political zeal and their lack of scrupulosity. Now they have come close to persuading politicians all over the Western world that we must change the way we live or sink beneath the waves.

But with the leaked emails known as Climategate more people are beginning to see that deception, not science, has been their principal weapon. And we see also that Wikipedia has lent itself to that deception.

The political exploitation of science has gone on for some time — discrediting nuclear power in addition to the use of oil and coal has been just one of its several goals. One unintended consequence, as Fred Singer said recently, is that the public may begin to disbelieve everything that begins “science says.” In the present climate, that might be healthy, but in the long run it would not work to America’s or the world’s advantage.

A footnote: Mr. Wales may be interested to know that the responses to Solomon’s article were quite civil, surprisingly so given the shocking nature of his charges. Here are two. I particularly commend the second:

[From an academic] “I will not accept any references from Wikipedia in any paper I review from here on out until this is resolved.”

“I see that a banner ad is appearing on most Wikipedia pages asking for ‘donations’…. I think I’ll contribute to more worthwhile charities.”

For myself, I shall continue to investigate this issue over the next few days, and I hope to post a follow-up next week.

Special Report – Global Warming

Tulsa Beacon

December 24, 2009

While the United Nations, President Obama and former Vice President Al Gore look for billions of dollars to fight “global warming,” scientists all over the world are debunking the theory as “bad science” and political manipulation.

U.S. Secretary of State Hillary Clinton said last week in a United Nations climate summit in Copenhagen that America should lead the way in spending $100 billion to fight climate change (or global warming).

Lawrence Solomon has written a book, “The Deniers: The World Renown Scientists Who Stood Up Against Global Warming, Hysteria, Political Persecution and Fraud.” (Buy the book here).

In the book, Solomon chronicles the opposition to global warming and the science that contradicts the views of Obama, Gore and the United Nations.

Dr. Edward J. Wegman is director of the Center for Computational Statistics at George Mason University, chair of the National Academy of Sciences Committee on Applied and Theoretical Statistics and a board member of the American Statistical Association.

The U.S. House Energy and Commerce Committee asked him to assess the “hockey stick graph,” a key global warming tool created by Michael Mann of The University of Massachusetts.

The hockey stick graph shows that for most of the past one thousand years, temperatures in the Northern Hemisphere were cooling – until 1900. Then temperatures began to rise through the 1990s as mankind began to industrialize and use more hydrocarbons for energy. Mann claimed that the 20th Century was the warmest of the past millennium, the 1990s was the warmest decade and 1998 was the warmest year.

In 1990, the Intergovernmental Panel on Climate Change published a graph that showed a warming period in the Middle Ages (14th Century) that led to the “Little Ice Age,” from which we have been emerging since the early 1700s.

Mann’s hockey stick graph eliminated the Medieval Warming Period, which made the 20th Century warming look more dramatic.

According to Solomon, “More than any other single piece of evidence, (the hockey stick) made global warming a serious popular and political issue.”

The United Nations IPCC 2001 report on global warming made the hockey stick graph the centerpiece on its report to international policymakers.

A Canadian mining scientist named Stephen McIntire examined the hockey stick data and found that the 1600s, not the 1900s, were the hottest century. That didn’t necessarily disprove global warming but it showed that Mann’s graph was an enormously effective prop. Professor Ross McKitrick, an economist at The University of Guelph, has joined McIntire in calling the hockey stick graph a “phony.”

The United Nations decided that Mann’s credentials were more impressive than McIntire’s.

Then, at the request of Congress, Wegman assembled a panel of expert statisticians, including the board of the American Statistical Association.

They agreed to repudiate Mann’s hockey stick graph and vindicate McIntire and McKitrick.

“Our committee believes that the assessments that the decade of the 1990s was the hottest decade in a millennium and that 1998 was the hottest year in a millennium cannot be supported,” Wegman wrote.

When measuring temperature for one thousand years, statistics become important. Only recently did the world have accurate thermometers scattered all across the globe continuously measuring temperature.

Global warming theorists have to rely on sporadic and discontinous data such as tree rings, ice cores, lake and ocean sediment and other less reliable sources.

Wegman’s report showed that tree rings are not reliable to support the hockey stick graph.

So, why did so many rush to accept Mann’s graph?

Wegman said the peer process doesn’t work because there is “too much consensus.” Mann’s reviewers all came from a very tight-knit paleoclimate community that highly respected Mann.

Solomon writes that “the hockey stick experience has convinced Wegman that much of climate science should be taken with a grain of salt, since so many studies have been peer reviewed by reviewers unqualified in statistics.”

The IPCC dropped the hockey stick graph from its 2007 report – an indication of its lack of credibility.

Is the Earth warmer?

That is the key question for those who hold to global warming.

Dr. Vincent Gray, has a Ph.D. in physical chemistry from The University of Cambridge. He has published more than 100 scientific papers and wrote The Greenhouse Delusion: A Critique of Climate Change 2001.

He has called the IPCC (United Nations) process a “swindle.”

Gray is one of the “2,500 top scientists” from around the world that the IPCC cites as backing their reports. He wrote 1,900 comments on the final draft on a recent IPCC’s report.

“Right from the beginning, I have had difficulty with this procedure,” Gray wrote. “Penetrating questions often ended without any answer. Comments on the IPCC drafts were rejected without explanation and attempts to pursue the matter were frustrated indefinitely.”

His conclusion was that the information in the IPCC reports were “unsound.”

For example, Gray says that temperature stations are not properly stationed. Ninety percent are on the land while 70 percent of the Earth’s surface is covered by the oceans. Temperature stations are disproportionately located near cities, which are heat sources.

Geophysicist Syun-Ichi Akasofu, a founding director of the International Arctic Research Center of The University of Alaska in 1964 discovered the origin of storms in the aurora borealis. He has published more than 550 professional journal articles.

Akasofu says the Earth slowly warmed about one half of one degree Celcius during the 20th Century. That also happened over the course of the 18th and 19th centuries. The rate of warming has been fairly consistent since the Little Ice Age, which ended in 1900.

“The Earth may still be recovering from the Little Ice Age,” Akasofu said. If that is true, there is no need to blame greenhouse gases for warming in the 20th Century.

In other words, if there has been slight (one half degree) global warming, it is part of a cycle and not man made. The Norwegian Sea has been continuously receding since 1800 due to the North Atlantic Oscillation – a natural phenomenon.

Many glaciers advanced during the Little Ice Age and have been receding ever since, Akasofu states.

What is the impact of CO2 (carbon dioxide)?

The warmists believe that human activity and industrialization have increased the level of greenhouse gases in the atmosphere to the point of raising the Earth’s temperature – and thus leading to eventual climactic catastrophe.

Most scientists agree that carbon dioxide absorbs space-bound infrared radiation and leads to warming and increased evaporation at the Earth’s surface.

The question is how much of an impact it truly has.

Former Vice President Al Gore in his movie, An Inconvenient Truth, states that a rise in CO2 always brings about a rise in temperature.

But arctic data show a large rise and fall in temperature between 1920 and the early 1970s while the global average shows little change. A second major fluctuation happened in 1975. These correlate with changes in CO2 levels.

In other words, these normal fluctuations show a natural cycle that diminishes the greenhouse effect.

“Indeed, there is so far no definitive proof that most of the present warming is due to the greenhouse effect,” Akasofu said.

Arctic temperature had a cooling effect from 1940 to 1975 even though CO2 levels began to rise in 1940.

Akasofu said you cannot know the exact effect of CO2 without subtracting natural causes that are hard to measure.

The IPCC’s own climate change models show carbon dioxide to be irrelevant.

Dr. Tom Segalstad is head of the Geological Museum at The University of Oslo and was a former expert reviewer for the IPCC.

Cars are a source of CO2 emissions and so are people (as they exhale). The oceans absorb and release CO2. In fact, most scientists believe that CO2 can’t stay in the atmosphere for more than five years because it is absorbed in the oceans.

CO2 in the atmosphere and the oceans reach a stable balance when the oceans contain about 50 times more than the atmosphere.

Segalstad said that based on isotope mass balance calculations, if CO2 in the atmosphere had a lifetime of 50 to 200 years (as claimed by the United Nations), the atmosphere would have half of its current CO2 mass. That’s nonsense. The IPCC counters with a “missing sink” model that claims half of the CO2 is “hiding somewhere.”

Looking for the missing sink in the biosphere, carbon cycle modeling shows deforestation must have added a lot of CO2 to the atmosphere. Instead of finding a missing sink, the models find another CO2 source.

An error of “about three giga-tonnes of carbon annually not explained by a model would normally lead to complete rejection of the model and its hypotheses,” Segalstad said.

“It is all a fiction.”

Astrophysicist Nir Shaviv of Israel had logically concluded that increases in carbon dioxide and other gases led to the greenhouse effect. He thought greenhouse gases increased in the 20th Century due to human activity. Nothing else explained it, he thought.

Shaviv has changed his mind.

“…after carefully digging into the evidence, I realized that things are far more complicated than the story sold to us by many climate scientists or the stories regurgitated by the media,” Shaviv said.

Shaviv believes that CO2 plays only a subordinate role – a circumstantial one at best.

Man’s role is so uncertain that the Earth may have been cooling, Shaviv said. We understand the role of CO2 but we don’t understand other factors.

It’s like the man who lost his keys in the dark but looks for them a block away under a street light because the light there is better, Shaviv said.

“Solar activity can explain a large part of the 20th Century global warming,” Shaviv said. He thinks natural solar processes account for 80 percent of the warming.

He favors curbing the use of fossil fuels – not to prevent global warming but to lessen pollution.

Wikipedia’s hockey stick wars

Lawrence Solomon
Financial Post
December 23, 2009

Since my Saturday column described how Wikipedia editors have been feverishly rewriting climate history over much of the decade, fair-minded Wikipedians have been doing their best to correct the record. No sooner than they remove gross distortions, however, than the distortions are replaced. William Connolley, a Climategate member and Wikipedia’s chief climate change propagandist, remains as active as ever.

How does Wikipedia work and how do Connolley and his co-conspirators exercise control? Take Wikipedia’s page for Medieval Warm Period, as an example. In the three days following my column’s appearance, this page alone was changed some 50 times in battles between Connolley’s crew and those who want a fair presentation of history.

One of the battles concerns the so-called hockey stick graphs, which purport to show that temperatures over the last 2000 years were fairly stable until the last century, when temperatures rose rapidly to today’s supposedly dangerous and unprecedented levels.  In these graphs, the Medieval Warm Period – a period of several centuries around the year 1000 – appears to be a modest bump along the way. Before the hockey stick graphs began to be published about a decade ago, scientists everywhere – including those associated with the UN itself – viewed the Medieval Warm Period as much hotter than today. Rather than appearing as a modest bump compared to today’s high temperatures, the Medieval Warm Period looked more like a mountain next to the molehill that is today’s temperature increase.

The hockey stick graphs led to an upheaval in scientific understanding when the UN reversed itself and declared them bona fide. Soon after, the hockey stick graphs were shown to be bogus by a blue-chip panel of experts assembled by the U.S. Congress. The Climategate Emails confirm the blue-chip panel’s assessment – we now know that Climategate scientists themselves doubted the reliability of the hockey stick graphs.

With the hockey stick graphs so thoroughly discredited, you’d think they would become a footnote to a discussion of the Medieval Warm Period, or an object of amusement and curiosity. But no, on the Wikipedia page for the Medieval Warm Period, the hockey stick graph appears prominently at the top, as if it is settled science.

Because the hockey stick graph has become an icon of deceit and in no way an authority worthy of being cited, fair-minded Wikipedians tried to remove the graph from the page, as can be seen here. Exactly two minutes later, one of Connelley’s associates replaced the graph, restoring the page to Connelley’s original version, as seen here.

Battles like this occurred on numerous fronts, until just after midnight on Dec. 22, when Connolley reimposed his version of events and, for good measure, froze the page to prevent others from making changes — and to prevent the public, even in two-minute windows, from realizing that today’s temperatures look modest in comparison to those in the past. In the World of Wikipedia, as seen here, the hockey stick graph, and Connolley’s version of history, still rules.

Climategate: the corruption of Wikipedia

James Delingpole
Telegraph.co.uk
December 22, 2009

If you want to know the truth about Climategate, definitely don’t use Wikipedia. “Climatic Research Unit e-mail controversy”, is its preferred, mealy-mouthed euphemism to describe the greatest scientific scandal of the modern age. Not that you’d ever guess it was a scandal from  the accompanying article. It reads more like a damage-limitation press release put out by concerned friends and sympathisers of the lying, cheating, data-rigging scientists.

Which funnily enough, is pretty much what it is. Even Wikipedia’s own moderators acknowledge that the entry has been hijacked, as this commentary by an “uninvolved editor” makes clear.

Unfortunately, this naked bias and corruption has infected the supposedly neutral Wikipedia’s entire coverage of Anthropogenic Global Warming (AGW) theory. And much of this, as Lawrence Solomon reports in the National Post, is the work of one man, a Cambridge-based scientist and Green Party activist named William Connolley.

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 band 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.

Connolley has supposedly been defrocked as a Wikipedia administrator. Or so Wikipedia claimed in its feeble, there’s-really-not-much-we-can-do response to anxious questions from one of Watts Up With That’s readers.

In September 2009, the Wikipedia Arbitration Committee revoked Mr. Connolley’s administrator status after finding that he misused his administrative privileges while involved in a dispute unrelated to climate warming.

If this is true, it doesn’t seem to have made much difference to his creative input on the Wikipedia’s entries. Here he is – unless its just someone with an identical name – busily sticking his oar in to entries on the Medieval Warm Period (again) and the deeply compromised, soon-to-be-leaving (let’s hope) IPCC head Dr Rajendra Pachauri. And here he is again just three days ago, removing a mention of Climategate from Michael Mann’s entry. And here is an example of one of his Wikipedia chums – name of Stephan Schulz – helping to cover up for him by ensuring that no mention of that embarrassing Lawrence Solomon article appears on Connolley’s Wikipedia entry. And here he is deleting criticism of himself.

Connolley, it should also be noted, was one of the founder members of Real Climate – the friends-of-Michael-Mann propaganda outfit (aka “The Hockey Team”) which, in the guise of disinterested science, pumps out climate-fear-promoting hysteria on AGW and tries to discredit anyone who disagrees with the ManBearPig “consensus”.

Here he is, for example, being bigged up in a 2006 email from Michael Mann:

>> I’ve attached the piece in word format. Hyperlinks are still there,
>> but not clickable in word format. I’ve already given it a good
>> go-over w/ Gavin, Stefan, and William Connelley (our internal “peer
>> review” process at RC), so I think its in pretty good shape. Let me
>> know if any comments…
>>

and here are some of his associates:

Get that? The guy who has been writing Wikipedia’s entry on Climategate (plus 5,000 others relating to “Climate Change”) is the bosom buddy of the Climategate scientists.

Nope, this isn’t a problem that is going to go away. Wikipedia may well be beyond redemption – as this useful resource site for Wiki-inaccuracies would seem to suggest. Like so many hippyish notions, Jimmy Wales’s idea of a free encyclopedia for everyone was a noble intention which has been cruelly and horribly abused by some very ugly people.

Do you want to know just how ugly? I’ve been saving the worst till last. Here it is: William Connelley’s Wikipedia photograph.

UPDATE: (thanks, wondrous Thomas 33 for your delving). Et Tu, Jimmy Wales? It seems that the dread Connolley once earned the approbation of the Wiki-King himself, as he boasts here on an old blog:

Aldyen Donnelly: US carbon taxes and Canadian exporters

I have talked to EPA officials, staff in bill-drafting senators and house members’ offices and two presidential advisors on this matter on a number of occasions, including in the last week.

Every time I ask about the role of tax measures in any North American continental carbon/energy market design, they respond that these are revenues, not emission reduction measures. Obviously, if emission taxes are generating revenues then, by definition, they are not resulting in emission reductions.

The US representatives, like most other governments, are keen on securing any new revenues they can, especially through taxes that are indirect, spread out and which are not going to be specifically itemized on taxpayer invoices. But when it comes to cross border considerations in US climate change law, the US is not willing to assign a "credit" against the standard carbon tariff for any Canadian exports that have been "taxed" in Canada or internationally.

Again, this gets back to the fact that a tax can either be revenue generating or drive emissions down, but not both.

Governments can elect to price the tax sub-optimally (as BC and Quebec have done) to generate revenues or max out the tax to change behavior.

The US decision-influencers tell me they don’t want to get into trade disputes centering on the question of whether taxes are high enough to be legitimate emission control measures or are just revenue tools. So they are all agreed that when it comes to establishing GHG factors to determine the volume of US GHGs, US importers of Canadian products shall be required to buy, or any direct carbon-based tariffs on Canadian exports, the US authorities will ignore any and all taxes that might be paid by those exporters in Canada or to international agencies. And they expect Canada to treat US exports the same way. 

If Canada’s tax regime proves an effective mechanism to change behavior, they say, then Canadian GHGs will decline and the US trans-border charges on our exports will decline accordingly.  Though the US rules in development do not leave room for gaming between exports and domestic consumption of GHG-intensive goods and services.

Please also note the aid/international tax game that the US is now playing and Japan initiated in 2002.

UN treaty language insists that all CDM CER (developing credit) spending and any new international taxes that might be agreed have to be paid over and above national commitments to Official Development Assistance (ODA, aid). The UN envisions that the UN will collect all of the new international taxes and use the revenues to fund new UN assistance projects in developing nations.

But between 1999 and 2002, directly preparing to ratify the Kyoto Protocol, Japan cut its ODA budget by a full US$4 billion, and put $2 billion in a CDM CER account. They put $1 billion in an account to fund new UN Human Resource initiatives. Then, they said, the last $1 billion would offset Japanese corporations’ CER purchases. They put a domestic tax credit in place to offset Japanese corporations’ costs of buying CERs.

The Japanese government was open and transparent that they were cutting ODA to finance their Kyoto Protocol commitments.

While this was an obvious breach of the Kyoto Protocol, the UN did not call Japan on it.  I find members of the Obama administration now pretty open about their intention to let the UN find new sources of revenues, but then to cut back the US’s continuing direct support for the UN proportionately. The big difference between the Bill Clinton and Obama administrations is there appears to be little love lost for the UN in the current White House.

What is A Better Path Forward?

The question of whether the UN/World Bank and other supra-national institutions should be able to tax certain international activities to raise revenues should be considered in isolation, and should be recognized, formally, as a strategy to replace funding that the UN is likely to lose over the next few years.

Any final international climate change treaty should oblige:

  • participating nations to prepare GHG inventories for their direct and indirect aid portfolios and add the aid account to their official national GHG inventories and progress reports and
  • large supra-national to publish and manage their aid and lending portfolio GHG inventories and adopt GHG reduction commitments just as if they were sovereign national parties to the treaty.

Rather than fighting over whether spending on developing nation credits (over 80% of which are "hot air") is incremental to our existing aid budgets, we should subject our aid budgets to the same GHG accounting and reduction targets that we adopt for all other national activities.
