Get the Most Out of Your Solar PV Installation

Installing solar PV on your home is a great way to reduce your electricity bills and your carbon footprint and there are easy ways to get the most out of your system, therefore maximising your savings and also doing your bit to help save the world! Some small lifestyle changes and planning ahead can make all the difference to your savings.
  • Use appliances during the day: Solar panels work by converting the energy in sunlight into electricity. This is done mostly during optimum conditions – the daytime. Therefore by using appliances during the day, the electricity being generated is used straight away. Washing machines, dishwashers and vacuum cleaners especially use a lot of power. When using them in daylight, even a low light day will supplement the energy usage, and a sunny day may power the whole operation.
  • Pull the plug: many electrical appliances run in the background when they are not switched off at the plug, and this can use more electricity than you realise. Switch off your TV, chargers, and any other items that could be running on standby.
  • Stagger your electricity usage: Using electricity during the day is the most effective way to get the most out of your solar panels. However if you use everything at once, you may still be importing the extra electricity needed from the grid. Stagger your energy usage throughout the day to maximise your solar energy; and keep this in mind when setting timers too
  • Generate hot water from solar: By installing a solar immersion switch alongside your solar PV system, you can use the excess electricity generated by your PV to power your immersion heater. This means that you would get as much of the free energy generated by your system as possible. The switch works with intelligent controls which react to household demand, which means that is more electricity is needed somewhere else in your home, the electricity will be diverted there.
  • Monitor your electricity: you can use a system monitor to access your generation and electricity consumption. Some monitors will work with your computer, smart phone or tablet so that you can access these figures easily. By utilising this information, you can work out how much energy you are generating at a given time, and then tailor your electricity usage to this so that you only use the energy your solar is producing.
  • Convert your lighting to low energy: as most lights are used at night when the PV system is not generating, it is beneficial to install low energy or LED light bulbs. This will reduce the amount of energy the light needs to power itself, which will save you money on your bills.

Some of these actions are small changes you can make to your lifestyle, and others are things that may need some investment in time or money. When this is the case, it is vital to keep in mind how much these products/actions could save you in the long run, and you can guarantee that it will be worth it.

Survey results suggest over 80% of farmers want rooftop solar power

A recent survey conducted by Farming Futures has found that 80% of farmers in the UK want to have solar photovoltaics installation on their roofs within the next three years. These results prove that farmers’ interest in generating renewable electricity has increased dramatically since the launch of the feed-in tariff (FiT), which was launched in April this year.

Recent press coverage has concentrated on the issue of solar installations on farmland and open fields; however the survey’s findings indicate that just under 20% of farmers considering solar want it at this scale, with the majority considering the technology for large farm buildings.

However, while the survey did outline the success of the FiT, it did also highlight farmers’ relatively poor understanding of how the subsidy mechanism works. Only 55.2% understood to what extent they could actually earn from the FiT while 25.4% thought payment was only for generation, or export (19.4%).

Dr. Jonathan Scurlock, Chief Advisor, Renewable Energy and Climate Change at the National Farmers' Union said, "These findings certainly reflect what our members have been saying. Agricultural and horticultural buildings present ideal platforms for solar PV, and small-to-medium sized roof-mounted systems are likely to be an attractive investment. It's hugely encouraging to see our farming industry become stronger through the generation of power, and helping this country reduce its reliance on fossil fuels."

Stephen Frankel, a farmer from Wadebridge said, "We installed solar PV on our barn roof this year, and immediately starting saving on our bills and earning extra income thanks to the FiT. Traditionally, farming revenue is quite seasonal, but now we’re making money by creating clean energy we have the peace of mind of another income, and we’re doing our bit reducing our carbon footprint. I’d recommend any farmer to consider this – our land brings us so much value, so why not our roofs?”

Sustainable farming is at the core of a healthy future for the UK, and it’s great to see farmers recognising the opportunity they now have with solar. Urban Energy welcome the opportunity to help UK farmers get maximum return from their property. Solar power is a sophisticated active industrial building product designed to work with business.

The main findings of the survey are:

*88.1% of Farmers are currently considering renewables on their farm

*Since the introduction of the FiT in April 2010, 83.2% of farmers have considered renewables; as the financial incentive secures a return on investment for 25 years

*Of those considering renewables, an overwhelming 93.3% are interested in solar PV, with wind energy as the second choice

*Of those who have already invested in renewables, only 28.6% have done so in PV; but 85.7% are now considering it

*82.2% of farmers are considering solar PV (93.3% of those interested in renewables (88.1%)

*80.6% of those surveyed are considering solar on a roof

*89.8% of those interested in investing in renewables are planning to do so within the next two years, which would enable them to take advantage of the FiT

*However, only 55.2% understood to what extent they could actually earn from the FiT; being paid for all electricity generated and consumed, as well as that exported. The remainder (25.4%) thought payment was only for generation, or export (19.4%)

New Conservative British Govt. Agrees on More Feed-in Tariffs

Less than two months after Britain's Labour Party launched its highly regarded feed-in tariff (FiT) program, the newly elected conservative government has announced the program will be expanded. The announcement is included in the coalition government's agreement published as the new government took office.
The coalition government of the Conservative Party, and the Liberal Democrats have issued statements in the past supporting the principle of feed-in tariffs for developing Britain's renewable energy potential.

The Tories said during the campaign that they would scrap the current Renewable Obligation (RO), the British form of Renewable Portfolio Standards, and use feed-in tariffs to develop renewable energy.

Britain is one of Europe's renewable energy laggards. Despite the best wind resource in Europe, the county has only developed 4,000 megawatts (MW) of generation after two decades of effort. During the same period, Germany has installed 25,000 MW of wind capacity. France, itself a laggard, has installed as much as Britain in half the time. Both Germany and France use feed-in tariffs.

The agreement implies that the new government will expand the feed-in tariff policy further to encompass more than the "microgenerators" covered under the existing program while maintaining the Renewable Obligation Certificates that are the heart of the RO program. Specifically, the agreement states: "The full establishment of feed-in tariff systems in electricity - as well as the maintenance of banded ROCs"

In another measure of how far the conservatives has moved toward the rapid development of renewable energy can be found in the Tory manifesto published prior to the election. The manifesto's section on sustainability singles out Freiburg, Germany for adulation with a picture of the solar seidlung in the city's famed Vauban quarter. The solar development in the picture was all driven by Germany's "banded" system of feed-in tariffs, since emulated in Britain's new program.

The coalition agreement also stipulates that the two parties will "seek to increase the target for energy from renewable sources" over that of the previous Labour government.

The agreement also has an intriguing passage on nuclear power that may be a harbinger of a change in conservative policies in other English-speaking countries.

"Liberal Democrats have long opposed any new nuclear construction. Conservatives, by contrast, are committed to allowing the replacement of existing nuclear power stations provided they are subject to the normal planning process for major projects (under a new national planning statement) and provided also that they receive no public subsidy."

Nuclear plants receive various subsidies in both Canada and the US, most famously exemption from risk insurance. Further, the Obama administration announced earlier this year a new subsidy program for new nuclear construction in the US.

Only time will tell whether the statement was simply rhetorical and the Tories define "subsidies" narrowly enough to permit the government to fund the new reactors proposed by Electricité de France.

The Case for Global Warming Stronger Than Ever

One of the many crimes that climate scientists have been accused of lately is that they claim absolute certainty in a field of research fraught with uncertainty. Sure, the planet is warming, say skeptics, but that's happened throughout Earth's history, long before humans were burning fossil fuels. So, how can we be sure this isn't just a natural phenomenon?

Yet a search through the much vilified Intergovernmental Panel on Climate Change (IPCC) reports shows that absolute certainty is notably absent. In the most recent document, for example, published in 2007, the authors write: "Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG [that is, human-generated greenhouse gas] concentrations."

If that doesn't sound definitive, it's because, as the authors freely admit, it isn't: climate science continues to evolve as new evidence comes in. Indeed, back in 2006, even before the latest IPCC report was complete, researchers in Britain were already planning to launch an update. Helmed by the U.K.'s Met Office (formerly known as the Meteorological Office), the update, published March 5 in the journal Wiley Interdisciplinary Reviews: Climate Change, is based on more than 100 peer-reviewed post-IPCC studies. The new data may shift the evidence for climate change, but none of it weakens what the IPCC said three years ago.

By looking at a wide range of observations from all over the world, the Met Office study concludes that the fingerprint of human influence on climate is stronger than ever. "We can say with a very high significance level that the effects we see in the climate cannot be attributed to any other forcings [factors that push the climate in one direction or another]," says study co-author Gabriele Hegerl of the University of Edinburgh.

Plenty of these climate effects had already been observed at the time of the 2007 IPCC report, including warming temperatures, shifts in rainfall (wet regions getting wetter, dry regions getting drier) and the increase in summer meltback of Arctic sea ice. Those patterns have continued, and in some cases gotten worse.

Some entirely new observations have been recorded as well. In its 2007 report, the IPCC did not include the impact of Greenland's or Antarctica's melting glaciers in its estimate of future sea-level rise, saying it lacked sufficient data. But now the speed-up of flow from these glaciers has been documented. And while the IPCC noted in 2007 that every continent had warmed throughout the 20th century except Antarctica, that continent has now been shown to be warming as well — very likely due to man-made influences, says Hegerl. (See the top 10 scientific discoveries of 2009.)

There's plenty more evidence in the Met Office report to support global warming. But the question from critics remains: how can we be sure this isn't just a natural phenomenon? Scientists haven't done a good enough job of communicating how they distinguish human versus natural influences, says Hegerl. The answer lies in climate models — massive computer simulations that allow the scientists to project climate effects in various scenarios, including those in which humans do not emit any greenhouses at all. "We go out of our way to check out other explanations — by assuming it's all explained by solar activity, or by solar activity plus volcanoes, or by combinations of any of the other natural forcings known to affect climate," says Hegerl.

According to the models, none of those combinations can produce the climate patterns currently being observed in the real world. Add the greenhouse gases that we know humans are generating (and which we've known since the 1800s tend to warm the Earth, all other things being equal), and the simulations finally come close to matching the real world. Its possible, albeit far-fetched, that the simulations are defective. It is even less possible that all of them (and there are many) are defective in the direction of overstating humanity's contribution to warming.

Again, none of the evidence adds up to absolute certainty, a rare commodity in any field of science. On Wednesday, U.N. Secretary General Ban Ki-moon announced that an independent panel of scientists, representing national science academies from around the world, would review the IPCC's research procedures — an effort to account for the 2007 report's mistakes, for which the IPCC has come under hard criticism. But while the U.N. group may benefit publicly from more transparency, it won't change the fact that more than 99% of the scientific details in the 2007 report have already withstood the most intense scrutiny. The fact that climate change evidence that was "very likely" a few years ago has now been declared likelier still by the comprehensive Met Office report suggests that the evidence for human-caused climate change is getting better all the time.

The Denial Industry

For years, a network of fake citizens' groups and bogus scientific bodies has been claiming that science of global warming is inconclusive. They set back action on climate change by a decade. But who funded them? Exxon's involvement is well known, but not the strange role of Big Tobacco. In the first of three extracts from his new book, George Monbiot tells a bizarre and shocking new story.

ExxonMobil is the world's most profitable corporation. Its sales now amount to more than $1bn a day. It makes most of this money from oil, and has more to lose than any other company from efforts to tackle climate change. To safeguard its profits, ExxonMobil needs to sow doubt about whether serious action needs to be taken on climate change. But there are difficulties: it must confront a scientific consensus as strong as that which maintains that smoking causes lung cancer or that HIV causes Aids. So what's its strategy?

The website Exxonsecrets.org, using data found in the company's official documents, lists 124 organisations that have taken money from the company or work closely with those that have. These organisations take a consistent line on climate change: that the science is contradictory, the scientists are split, environmentalists are charlatans, liars or lunatics, and if governments took action to prevent global warming, they would be endangering the global economy for no good reason. The findings these organisations dislike are labelled "junk science". The findings they welcome are labelled "sound science".

Among the organisations that have been funded by Exxon are such well-known websites and lobby groups as TechCentralStation, the Cato Institute and the Heritage Foundation. Some of those on the list have names that make them look like grassroots citizens' organisations or academic bodies: the Centre for the Study of Carbon Dioxide and Global Change, for example. One or two of them, such as the Congress of Racial Equality, are citizens' organisations or academic bodies, but the line they take on climate change is very much like that of the other sponsored groups. While all these groups are based in America, their publications are read and cited, and their staff are interviewed and quoted, all over the world.

By funding a large number of organisations, Exxon helps to create the impression that doubt about climate change is widespread. For those who do not understand that scientific findings cannot be trusted if they have not appeared in peer-reviewed journals, the names of these institutes help to suggest that serious researchers are challenging the consensus.

This is not to claim that all the science these groups champion is bogus. On the whole, they use selection, not invention. They will find one contradictory study - such as the discovery of tropospheric cooling, which, in a garbled form, has been used by Peter Hitchens in the Mail on Sunday - and promote it relentlessly. They will continue to do so long after it has been disproved by further work. So, for example, John Christy, the author of the troposphere paper, admitted in August 2005 that his figures were incorrect, yet his initial findings are still being circulated and championed by many of these groups, as a quick internet search will show you.

But they do not stop there. The chairman of a group called the Science and Environmental Policy Project is Frederick Seitz. Seitz is a physicist who in the 1960s was president of the US National Academy of Sciences. In 1998, he wrote a document, known as the Oregon Petition, which has been cited by almost every journalist who claims that climate change is a myth.

The document reads as follows: "We urge the United States government to reject the global warming agreement that was written in Kyoto, Japan, in December 1997, and any other similar proposals. The proposed limits on greenhouse gases would harm the environment, hinder the advance of science and technology, and damage the health and welfare of mankind. There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth."

Anyone with a degree was entitled to sign it. It was attached to a letter written by Seitz, entitled Research Review of Global Warming Evidence. The lead author of the "review" that followed Seitz's letter is a Christian fundamentalist called Arthur B Robinson. He is not a professional climate scientist. It was co-published by Robinson's organisation - the Oregon Institute of Science and Medicine - and an outfit called the George C Marshall Institute, which has received $630,000 from ExxonMobil since 1998. The other authors were Robinson's 22-year-old son and two employees of the George C Marshall Institute. The chairman of the George C Marshall Institute was Frederick Seitz.

The paper maintained that: "We are living in an increasingly lush environment of plants and animals as a result of the carbon dioxide increase. Our children will enjoy an Earth with far more plant and animal life than that with which we now are blessed. This is a wonderful and unexpected gift from the Industrial Revolution."

It was printed in the font and format of the Proceedings of the National Academy of Sciences: the journal of the organisation of which Seitz - as he had just reminded his correspondents - was once president.

Soon after the petition was published, the National Academy of Sciences released this statement: "The NAS Council would like to make it clear that this petition has nothing to do with the National Academy of Sciences and that the manuscript was not published in the Proceedings of the National Academy of Sciences or in any other peer-reviewed journal. The petition does not reflect the conclusions of expert reports of the Academy."

But it was too late. Seitz, the Oregon Institute and the George C Marshall Institute had already circulated tens of thousands of copies, and the petition had established a major presence on the internet. Some 17,000 graduates signed it, the majority of whom had no background in climate science. It has been repeatedly cited - by global-warming sceptics such as David Bellamy, Melanie Phillips and others - as a petition by climate scientists. It is promoted by the Exxon-sponsored sites as evidence that there is no scientific consensus on climate change.

All this is now well known to climate scientists and environmentalists. But what has been discovered while researching this issue is that the corporate funding of lobby groups denying that manmade climate change is taking place was initiated not by Exxon, or by any other firm directly involved in the fossil fuel industry. It was started by the tobacco company Philip Morris.

In December 1992, the US Environmental Protection Agency published a 500-page report called Respiratory Health Effects of Passive Smoking. It found that "the widespread exposure to environmental tobacco smoke (ETS) in the United States presents a serious and substantial public health impact. In adults: ETS is a human lung carcinogen, responsible for approximately 3,000 lung cancer deaths annually in US non-smokers. In children: ETS exposure is causally associated with an increased risk of lower respiratory tract infections such as bronchitis and pneumonia. This report estimates that 150,000 to 300,000 cases annually in infants and young children up to 18 months of age are attributable to ETS."

Had it not been for the settlement of a major class action against the tobacco companies in the US, we would never have been able to see what happened next. But in 1998 they were forced to publish their internal documents and post them on the internet.

Within two months of its publication, Philip Morris, the world's biggest tobacco firm, had devised a strategy for dealing with the passive-smoking report. In February 1993 Ellen Merlo, its senior vice-president of corporate affairs, sent a letter to William I Campbell, Philip Morris's chief executive officer and president, explaining her intentions: "Our overriding objective is to discredit the EPA report ... Concurrently, it is our objective to prevent states and cities, as well as businesses, from passive-smoking bans."

To this end, she had hired a public relations company called APCO. She had attached the advice it had given her. APCO warned that: "No matter how strong the arguments, industry spokespeople are, in and of themselves, not always credible or appropriate messengers."

So the fight against a ban on passive smoking had to be associated with other people and other issues. Philip Morris, APCO said, needed to create the impression of a "grassroots" movement - one that had been formed spontaneously by concerned citizens to fight "overregulation". It should portray the danger of tobacco smoke as just one "unfounded fear" among others, such as concerns about pesticides and cellphones. APCO proposed to set up "a national coalition intended to educate the media, public officials and the public about the dangers of 'junk science'. Coalition will address credibility of government's scientific studies, risk-assessment techniques and misuse of tax dollars ... Upon formation of Coalition, key leaders will begin media outreach, eg editorial board tours, opinion articles, and brief elected officials in selected states."

APCO would found the coalition, write its mission statements, and "prepare and place opinion articles in key markets". For this it required $150,000 for its own fees and $75,000 for the coalition's costs.

By May 1993, as another memo from APCO to Philip Morris shows, the fake citizens' group had a name: the Advancement of Sound Science Coalition. It was important, further letters stated, "to ensure that TASSC has a diverse group of contributors"; to "link the tobacco issue with other more 'politically correct' products"; and to associate scientific studies that cast smoking in a bad light with "broader questions about government research and regulations" - such as "global warming", "nuclear waste disposal" and "biotechnology". APCO would engage in the "intensive recruitment of high-profile representatives from business and industry, scientists, public officials, and other individuals interested in promoting the use of sound science".

By September 1993, APCO had produced a "Plan for the Public Launching of TASSC". The media launch would not take place in "Washington, DC or the top media markets of the country. Rather, we suggest creating a series of aggressive, decentralised launches in several targeted local and regional markets across the country. This approach ... avoids cynical reporters from major media: less reviewing/challenging of TASSC messages."

The media coverage, the public relations company hoped, would enable TASSC to "establish an image of a national grassroots coalition". In case the media asked hostile questions, APCO circulated a sheet of answers, drafted by Philip Morris. The first question was:

"Isn't it true that Philip Morris created TASSC to act as a front group for it?

"A: No, not at all. As a large corporation, PM belongs to many national, regional, and state business, public policy, and legislative organisations. PM has contributed to TASSC, as we have with various groups and corporations across the country."

There are clear similarities between the language used and the approaches adopted by Philip Morris and by the organisations funded by Exxon. The two lobbies use the same terms, which appear to have been invented by Philip Morris's consultants. "Junk science" meant peer-reviewed studies showing that smoking was linked to cancer and other diseases. "Sound science" meant studies sponsored by the tobacco industry suggesting that the link was inconclusive. Both lobbies recognised that their best chance of avoiding regulation was to challenge the scientific consensus. As a memo from the tobacco company Brown and Williamson noted, "Doubt is our product since it is the best means of competing with the 'body of fact' that exists in the mind of the general public. It is also the means of establishing a controversy." Both industries also sought to distance themselves from their own campaigns, creating the impression that they were spontaneous movements of professionals or ordinary citizens: the "grassroots".

But the connection goes further than that. TASSC, the "coalition" created by Philip Morris, was the first and most important of the corporate-funded organisations denying that climate change is taking place. It has done more damage to the campaign to halt it than any other body.

TASSC did as its founders at APCO suggested, and sought funding from other sources. Between 2000 and 2002 it received $30,000 from Exxon. The website it has financed - JunkScience.com - has been the main entrepot for almost every kind of climate-change denial that has found its way into the mainstream press. It equates environmentalists with Nazis, communists and terrorists. It flings at us the accusations that could justifably be levelled against itself: the website claims, for example, that it is campaigning against "faulty scientific data and analysis used to advance special and, often, hidden agendas". I have lost count of the number of correspondents who, while questioning manmade global warming, have pointed me there.

The man who runs it is called Steve Milloy. In 1992, he started working for APCO - Philip Morris's consultants. While there, he set up the JunkScience site. In March 1997, the documents show, he was appointed TASSC's executive director. By 1998, as he explained in a memo to TASSC board members, his JunkScience website was was being funded by TASSC. Both he and the "coalition" continued to receive money from Philip Morris. An internal document dated February 1998 reveals that TASSC took $200,000 from the tobacco company in 1997. Philip Morris's 2001 budget document records a payment to Steven Milloy of $90,000. Altria, Philip Morris's parent company, admits that Milloy was under contract to the tobacco firm until at least the end of 2005.

He has done well. You can find his name attached to letters and articles seeking to discredit passive-smoking studies all over the internet and in the academic databases. He has even managed to reach the British Medical Journal: I found a letter from him there which claimed that the studies it had reported "do not bear out the hypothesis that maternal smoking/ passive smoking increases cancer risk among infants". TASSC paid him $126,000 in 2004 for 15 hours' work a week. Two other organisations are registered at his address: the Free Enterprise Education Institute and the Free Enterprise Action Institute. They have received $10,000 and $50,000 respectively from Exxon. The secretary of the Free Enterprise Action Institute is Thomas Borelli. Borelli was the Philip Morris executive who oversaw the payments to TASSC.

Milloy also writes a weekly Junk Science column for the Fox News website. Without declaring his interests, he has used this column to pour scorn on studies documenting the medical effects of second-hand tobacco smoke and showing that climate change is taking place. Even after Fox News was told about the money he had been receiving from Philip Morris and Exxon, it continued to employ him, without informing its readers about his interests.

TASSC's headed notepaper names an advisory board of eight people. Three of them are listed by Exxonsecrets.org as working for organisations taking money from Exxon. One of them is Frederick Seitz, the man who wrote the Oregon Petition, and who chairs the Science and Environmental Policy Project. In 1979, Seitz became a permanent consultant to the tobacco company RJ Reynolds. He worked for the firm until at least 1987, for an annual fee of $65,000. He was in charge of deciding which medical research projects the company should fund, and handed out millions of dollars a year to American universities. The purpose of this funding, a memo from the chairman of RJ Reynolds shows, was to "refute the criticisms against cigarettes". An undated note in the Philip Morris archive shows that it was planning a "Seitz symposium" with the help of TASSC, in which Frederick Seitz would speak to "40-60 regulators".

The president of Seitz's Science and Environmental Policy Project is a maverick environmental scientist called S Fred Singer. He has spent the past few years refuting evidence for manmade climate change. It was he, for example, who published the misleading claim that most of the world's glaciers are advancing, which landed David Bellamy in so much trouble when he repeated it last year. He also had connections with the tobacco industry. In March 1993, APCO sent a memo to Ellen Merlo, the vice-president of Philip Morris, who had just commissioned it to fight the Environmental Protection Agency: "As you know, we have been working with Dr Fred Singer and Dr Dwight Lee, who have authored articles on junk science and indoor air quality (IAQ) respectively ..."

Singer's article, entitled Junk Science at the EPA, claimed that "the latest 'crisis' - environmental tobacco smoke - has been widely criticised as the most shocking distortion of scientific evidence yet". He alleged that the Environmental Protection Agency had had to "rig the numbers" in its report on passive smoking. This was the report that Philip Morris and APCO had set out to discredit a month before Singer wrote his article.

I have no evidence that Fred Singer or his organisation have taken money from Philip Morris. But many of the other bodies that have been sponsored by Exxon and have sought to repudiate climate change were also funded by the tobacco company. Among them are some of the world's best-known "thinktanks": the Competitive Enterprise Institute, the Cato Institute, the Heritage Foundation, the Hudson Institute, the Frontiers of Freedom Institute, the Reason Foundation and the Independent Institute, as well as George Mason University's Law and Economics Centre. I can't help wondering whether there is any aspect of conservative thought in the United States that has not been formed and funded by the corporations.

While they have been most effective in the United States, the impacts of the climate-change deniers sponsored by Exxon and Philip Morris have been felt all over the world. Their arguments are seen endlessly repeated in Australia, Canada, India, Russia and the UK. By dominating the media debate on climate change during seven or eight critical years in which urgent international talks should have been taking place, by constantly seeding doubt about the science just as it should have been most persuasive, they have justified the money their sponsors have spent on them many times over. It is fair to say that the professional denial industry has delayed effective global action on climate change by years, just as it helped to delay action against the tobacco companies.
