A truly "bold," environmentally conscious state would go nuclear even more. Burlington will only really be the "best of" Green Places when local postcards show its charming leafy streets, with a view of Lake Champlain -- and a nuclear power plant looming in the background.
Former British Prime Minister Margaret Thatcher used to say that she was happy when her opposition resorted to attacking her or her colleagues’ character. It meant, she said, that they (her opponents) could not win the battle of ideas. If that is true, then the eco-extortionists are definitely on the run.
Accepted theories about man causing global warming are "lies" claims a controversial new TV documentary. 'The Great Global Warming Swindle' - backed by eminent scientists - is set to rock the accepted consensus that climate change is being driven by humans. The programme, to be screened on Channel 4 on Thursday March 8, will see a series of respected scientists attack the "propaganda" that they claim is killing the world's poor. Even the co-founder of Greenpeace, Patrick Moore, is shown, claiming African countries should be encouraged to burn more CO2. Nobody in the documentary defends the greenhouse effect theory, as it claims that climate change is natural, has been occurring for years, and ice falling from glaciers is just the spring break-up and as normal as leaves falling in autumn. A source at Channel 4 said: "It is essentially a polemic and we are expecting it to cause trouble, but this is the controversial programming that Channel 4 is renowned for."
Any U.S. law requiring renewable power sources to provide a greater portion of the country’s total electricity would not be enough to plug a rapid rise in emissions of the main gas linked to global warming, according to a new report. Amid rising concerns about fossil fuel supplies and emissions of greenhouse gases, several recently proposed U.S. bills called for a national renewable portfolio standard, a requirement that renewable energy sources, like wind, solar and small hydro, provide about 15 percent of U.S. power in about 20 years. Nearly half of U.S. states have passed their own renewable portfolio mandates. But if the country enacted such a law — without mandates that also cut power demand — U.S. carbon dioxide emissions would still rise 18 percent above current levels by 2026, according to the Wood MacKenzie report, titled “The Impact of a Federal Renewable Portfolio Standard.”
The UK grid does not have this huge resource "elsewhere" as we are an islanded electrical network. As wind grows toward government's targets, we would need either a ludicrous and vulnerable enlargement of our tiny connection to Europe or further investment in thermal generating capacity to support 'compulsory' windpower for a miniscule saving of CO2 emission.
The United Nations Foundation and Sigma Xi, The Scientific Research Society, today released "Confronting Climate Change: Avoiding the Unmanageable and Managing the Unavoidable," the final report of the Scientific Expert Group on Climate Change and Sustainable Development. The report, prepared for the upcoming meeting of the UN's Commission on Sustainable Development (CSD), outlines a roadmap for preventing unmanageable climate changes and adapting to unavoidable ones.
The CLOUD (Cosmics Leaving OUtdoor Droplets) laboratory experiment, CERN believes, will show the mechanisms through which the sun and cosmic rays can influence the formation of clouds and thus the climate. The CLOUD project will use a high-energy particle beam from an accelerator to closely duplicate cosmic rays found in the atmosphere. This will be the first time this technology will be brought to bear on global warming, the most controversial scientific question of the day. Also for the first time, very basic answers about the drivers of climate change may surface to dispel the general paucity of data on the subject. "By studying the micro-physical processes at work when cosmic rays hit the atmosphere, we can begin to understand more fully the connection between cosmic rays and cloud cover," CERN explains. "Clouds exert a strong influence on the Earth's energy balance, and changes of only a few per cent have an important effect on the climate."
REPORTS on the global-warming debate have now become part of our daily diet of news. Actors, musicians, politicians, columnists and even the occasional climate scientist all weigh in on how soon planetary disaster will strike, who's to blame and what we should do about it. With claims that manmade warming is anywhere from an undeniable fact to a hoax, anyone can be excused for feeling a little bit confused. The media is, almost by definition, most interested in extreme views on the issue, so reporting seldom reveals that broad scientific uncertainty still exists. In fact, a silent majority of scientists still think that global warming could end up falling anywhere between a real problem and a minor nuisance: They can see reasons for it going either way. Call them the global-warming moderates.
As Democratic leaders in Congress prepare to put climate change legislation on the agenda, some in the utility industry are arguing that it will take decades of investments and innovation to get substantial reductions in their emissions of greenhouse gases. Electric power companies, which emit about one-third of America’s global warming gases, could reduce their emissions to below the levels of 1990, but that would take about 20 years, no matter how much the utilities spend, according to a new industry study. The report, prepared by the Electric Power Research Institute, a nonprofit consortium, is portrayed as highly optimistic by its authors, who will present the findings on Thursday at an energy conference in Houston.
Global warming is a false myth and every serious person and scientist says so. It is not fair to refer to the U.N. panel. IPCC is not a scientific institution: it's a political body, a sort of non-government organization of green flavor. It's neither a forum of neutral scientists nor a balanced group of scientists. These people are politicized scientists who arrive there with a one-sided opinion and a one-sided assignment. Also, it's an undignified slapstick that people don't wait for the full report in May 2007 but instead respond, in such a serious way, to the summary for policymakers where all the "but's" are scratched, removed, and replaced by oversimplified theses. This is clearly such an incredible failure of so many people, from journalists to politicians. If the European Commission is instantly going to buy such a trick, we have another very good reason to think that the countries themselves, not the Commission, should be deciding about similar issues.
Q: Why should we be leery of the IPCC’s report -- or the summary of the report? A: Well, because the report is the end product of a political agenda, and it is the political agenda of both the extreme environmentalists who of course think we are destroying the world. But it’s also the political agenda of a group of people ... who believe that industrialization and development and capitalism and the Western way is a terrible system and they want to bring it down. They couldn’t do it by attacking energy because they know that would get the public’s back up very quickly. ... The vehicle they chose was CO2, because that’s the byproduct of industry and fossil-fuel burning, which of course drives the whole thing. They think, “If we can show that that is destroying the planet, then it allows us to control.” Unfortunately, you’ve got a bunch of scientists who have this political agenda as well, and they have effectively controlled the IPCC process.
Obviously, there are other ways in which the Lewis wind farm electricity can be managed so as to effect some small reductions in carbon emissions, but a figure of 600,000 tonnes per annum (your report, 6 February) is clearly absurd. The only long-term benefit of the Lewis wind farm will come at the end of it's 20-year lifetime, when, with the Beauly to Denny pylon line in place, the newly industrialised area of Barvas Moor will be the ideal site to place a 1000MW "clean energy" nuclear plant.
Mark Twain once complained that a lie can make it half way around the world before the truth gets its boots on. That's been the case of late in the climate change debate, as political and media activists attempt to stigmatize anyone who doesn't pay homage to their "scientific consensus." Last week the London Guardian published a story headlined, "Scientists Offer Cash to Dispute Climate Study." The story alleges that the American Enterprise Institute (AEI), a conservative-leaning think tank in Washington, collected contributions from ExxonMobil and then offered climate scholars $10,000 so they could lobby against global warming legislation.....Here are the facts as we've been able to collect them. AEI doesn't lobby, didn't offer money to scientists to question global warming, and the money it did pay for climate research didn't come from Exxon......One can only conclude from this episode that the environmental left and their political and media supporters now believe it is legitimate to quash debate on climate change and its consequences. This is known as orthodoxy, and, until now, science accepted the legitimacy of challenging it.
While everyone concedes that the Earth is about a degree Celsius warmer than it was a century ago, the debate continues over the cause and consequences. We don't deny that carbon emissions may play a role, but we don't believe that the case is sufficiently proven to justify a revolution in global energy use. The economic dislocations of such an abrupt policy change could be far more severe than warming itself, especially if it reduces the growth and innovation that would help the world cope with, say, rising sea levels. There are also other problems -- AIDS, malaria and clean drinking water, for example -- whose claims on scarce resources are at least as urgent as climate change.
All we have on which to pin the blame on greenhouse gases, says Dr. Shaviv, is "incriminating circumstantial evidence," which explains why climate scientists speak in terms of finding "evidence of fingerprints." Circumstantial evidence might be a fine basis on which to justify reducing greenhouse gases, he adds, "without other 'suspects.' "However, Dr. Shaviv not only believes there are credible "other suspects," he believes that at least one provides a superior explanation for the 20th century's warming. "Solar activity can explain a large part of the 20th-century global warming," he states, particularly because of the evidence that has been accumulating over the past decade of the strong relationship that cosmic-ray flux has on our atmosphere. So much evidence has by now been amassed, in fact, that "it is unlikely that [the solar climate link] does not exist."
To those who think that the installation of a wind plant, whether it be 4 turbines or 40, in what will become known as “formerly the beautiful seaside resort town of Eastham, Gateway to the Cape Cod National Seashore” will cut down on the carbon dioxide load, please think again. According to an investigation by the New York Times (12/28/06), wind power generates a big problem: it is unpredictable and often fails to blow when electricity is most needed, for example, on the hottest days when there is peak demand for air conditioning. According to Williams Bojorquez, director of system planning at the Electric Reliability Council of Texas, “power plants that run on coal or gas must be built along with every megawatt of wind capacity.” That is because, when the winds don’t blow, the grid must buy electricity from the next cheapest source of power, otherwise there would be rolling black-outs. Frank P. Prager, managing director of environmental policy at Xcel Energy, which serves eight states from North Dakota to Texas and states it is the nation’s largest retailer of wind energy, says that the higher the reliance on wind, the more an electricity transmission grid would need to keep conventional generators on stand-by - generally low-efficiency plants that run on natural gas or coal and can be started and stopped quickly. A study by Elfam, Denmark’s largest utilities company, in March, 2005, found that wind plants had not reduced the country’s carbon dioxide emission levels, because it has to be backed-up by conventional energy. A report by the Royal Academy of Engineers in Britain around the same time suggested that a conventional power station produces higher emissions when it is turned down to make room on the grid for wind-derived energy, and then ramps up when the wind power is insufficient.
The sun's increased irradiance over the last century, not C02 emissions, is responsible for the global warming we're seeing, says the celebrated scientist, and this solar irradiance also explains the great volume of C02 emissions. "It is no secret that increased solar irradiance warms Earth's oceans, which then triggers the emission of large amounts of carbon dioxide into the atmosphere. So the common view that man's industrial activity is a deciding factor in global warming has emerged from a misinterpretation of cause and effect relations." Dr. Abdussamatov goes further, debunking the very notion of a greenhouse effect. "Ascribing 'greenhouse' effect properties to the Earth's atmosphere is not scientifically substantiated," he maintains. "Heated greenhouse gases, which become lighter as a result of expansion, ascend to the atmosphere only to give the absorbed heat away." The real news from Saint Petersburg – demonstrated by cooling that is occurring on the upper layers of the world's oceans – is that Earth has hit its temperature ceiling. Solar irradiance has begun to fall, ushering in a protracted cooling period beginning in 2012 to 2015. The depth of the decline in solar irradiance reaching Earth will occur around 2040, and "will inevitably lead to a deep freeze around 2055-60" lasting some 50 years, after which temperatures will go up again.
In a sign that US electricity companies are recognising that the Democratic-controlled Congress will seek to impose aggressive climate change initiatives, six companies, including Exelon, one of the largest utility companies, on Wednesday endorsed a bill that would reduce their projected emissions by 25 per cent below projected levels by 2020.
The European Commission has set out a comprehensive package of measures to establish a new Energy Policy for Europe to combat climate change and boost energy security. A ten-point action plan sets out a series of ambitious targets on greenhouse gas emissions and renewable energy, along with proposals to create a more competitive energy market across the economic bloc, and includes a report on the implementation by the Member States of the internal market for gas and electricity as well as the results of an enquiry of the state of competition; a plan of for priority interconnections to create a European grid; proposals to promote sustainable power generation from fossil fuels; a roadmap and other initiatives to promote renewables, and; an analysis of the situation of nuclear energy in Europe. Based on the three central pillars of: a true internal energy market; accelerating the shift to low carbon energy; and energy efficiency, the mainstay of the new policy is a core objective for Europe to reduce greenhouse gas emissions by 20% by 2020 with the aim to increase this target to a 30% reduction by 2020 and 60-80% by 2050.
Your view: Is carbon offsetting a con? Holidaymakers are being misled by companies who guarantee to repair the damage flights do to the atmosphere, according to the first independent study of a fast-growing market. The report claims it is not possible to state categorically that buying any "carbon offset" — as Tony Blair did grudgingly last week to counter the global warming potential of his family's New Year break in Miami Beach — will neutralise the damage that flying causes to the atmosphere.
