22733 >> Kirsten Wiley: Good afternoon and welcome. My name is Kirsten Wiley. And I am here today to introduce and welcome Naomi Oreskes, who is visiting us as part of the Microsoft Research Visiting Speakers Series. Naomi is here today to discuss her book "Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues From Tobacco Smoke to Global Warming." 40 percent of Americans believe there's major scientific disagreement as to whether global warming is real; yet few working climate scientists would dispute that it is happening. There are a cadre of people who have been extremely effective at spreading confusion and seeding doubt about the dangers of cigarette smoking, the effects of acid rain, existence of the ozone hole, and the problems caused by secondhand smoke. Ideology and corporate interest has skewed public understanding and spread confusion on many of the most important issues of our time. Naomi is a professor of history in science studies at the University of California, San Diego. Her study Beyond the Ivory Tower, published in Science, was a milestone in the fight against global warming denial and was cited by Al Gore in an "Inconvenient Truth." Please join me in welcoming Naomi to Microsoft. [applause] >> Naomi Oreskes: Hi. Well, thanks very much for coming today. It's a pleasure to be here, especially because I was just two weeks ago at Google, and they all really like you in Mountain View. So I don't know what that's all about, but anyway it's fun to be here today. >>: [inaudible]. >> Naomi Oreskes: Is that what it is? But I'm bipartisan. I talk at Microsoft. I talk at Google. I don't take sides. In any event, so let's begin. For me, the story has a couple of different beginnings, but one of them was when Governor Schwarzenegger, my Austrian governor of the state of California announced an initiative for the state of California to commit to Kyoto level reductions in greenhouse gas emissions. An when Governor Schwarzenegger announced AB 32, he made the following declaration. He said: I say the debate is over. We know the science. We see the threat, and we know the time for action is now. Well, it's not every day you get to agree with a politician, but I thought that my governor had it right. And indeed, in the mid-2000s, it seemed that most American people agreed. A major poll done by the Gallop Polling organization in 2007 showed that 72 percent of American citizens were completely or mostly convinced that global warming caused by human activities was underway. Indeed, 62 percent of us believed that life on earth would continue without major disruption only if society took immediate and drastic action to reduce global warming. And, indeed, at that time even many contrarians had come around. One of them was Frank Luntz, the Republican polster and strategist, who in an interview in 2006 said: It's now 2006. So he was off to a good start. He got the year right. "I think most people would conclude that there is global warming taking place, and that the behavior of humans is affecting the climate." Now, Luntz is important to our story, because he was the author of a 2003 memo to Republican candidates running for public office in the United States in which he talked about the fact that Republican candidates were concerned vulnerable on environmental issues because opinion polls consistently showed that a large majority of the American people, 70 to 80 percent, believed that the government did have a role to play in protecting the environment and believed that Democrats were more committed to environmental protection than Republicans. So in order to address this vulnerability, particularly on the issue of climate change, Luntz advised Republican candidates running for public office to use the phrase "climate change" rather than "global warming," because, he wrote, "climate change is a lot less frightening." Continuing this mode, he argued that the way for Republican candidates to win the global warming debate was to emphasize scientific uncertainty and to insist that there was no consensus in the scientific community about the reality of anthropogenic climate change. So he wrote, and all the emphasis here is his: The scientific debate remains open. Voters believe that there's no consensus about global warming within the scientific community. Should the public come to believe that the scientific issues are settled, their views about global warming will change accordingly. Therefore, you need to continue to make the lack of scientific certainty a primary issue in the debate. Well, was Luntz correct? Was his position factually correct? The short answer is no. In 2001, two years before that memo, the Intergovernmental Panel on Climate Change, the world's leading organization of climate researchers from around the globe, had declared, in its third assessment report that: Human activities are modifying the concentration of atmospheric constituents that absorb or scatter radiant energy. Most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations. So that was in 2001, in the third assessment report of the IPCC, based on their review of the peer reviewed scientific literature. But, in fact, the scientific evidence had actually coalesced even earlier. In 1995, in the second assessment report of the IPCC, scientific experts had concluded that the balance of evidence suggests a discernible human impact on global climate. Now, I was interested in the question of whether or not these statements by the leadership of scientific organizations were consistent with what rank and file scientists had to say consistent with what you would actually find if you indeed read that peer reviewed scientific literature. That's what I did, along with some research assistants, we analyzed the scientific literature, using the ISI database, the Institute for Scientific Information, and asked the question how many articles published in peer reviewed scientific journals disagreed with that IPCC statement? And the answer was: None. This was a study of papers published in the decade 1990 to 2000, and we found that no articles published in the peer reviewed journals of our sample of about a thousand papers disagreed with or presented evidence to refute that statement. So I published that result in Science magazine in 2004. And the results surprised many people. In fact, it actually surprised me. But really, in hindsight, it shouldn't have been a surprise, because, in fact, the United States had signed, in 1992, the UN Framework Convention on Climate Change which committed the United States and 192 other signatories to acting to prevent dangerous anthropogenic interference in the climate system. And that framework convention was, in fact, based on the emerging scientific consensus that had developed at that time. And when our first President Bush, President George H.W. Bush, signed the framework convention, he called on world leaders to translate the document into concrete action to protect the planet. As a historian, I became interested in the question of what happened. If we had agreement among 193 nations in the world including the United States, including our Republican president about this issue, why didn't we take those concrete steps that our first President Bush promised us? So this is a historical story. I'm a historian of science. What I'd like to do today is give you a super brief history of the evolution of climate science, just hitting on a few of the major key historical milestones, then to tell you the story of the emergence of a political challenge to that science. It's a story of selling uncertainty, of merchandising doubt, and motivated by ideology, by the belief in the power of free markets, a kind of doctrinaire commitment to laissez-faire economics that was born and hardened in the Cold War. So scientifically our story begins with the work of John Tyndall, who, in the 1850s, first established what it means for something to be a greenhouse gas. In a series of experiments on the radiative properties of gasses Tyndall showed that both water vapor and carbon dioxide had the distinctive and important property of being highly transparent to visible light, but relatively opaque to infrared. Therefore, allowing visible light from the sun to come in, but tending to trap infrared that was reradiated from space to earth. And Tyndall recognized that the existence of greenhouse gasses in the atmosphere was a crucial fact about our planet, because without these greenhouse gasses, the earth would be as cold as the moon or Mars and quite inhospitable for life. Now, about 50 years later, Svante Arrhenius, the Swedish geochemist, one of the founders of chemical thermodynamics, recognized that when you burn fossil fuels, carbon dioxide is produced as a byproduct. And that carbon dioxide would likely to just remain in the atmosphere and would increase the greenhouse gas concentrations of the atmosphere, possibly changing the overall climate of the earth. Arrhenius did the first calculations of what the effect of doubling carbon dioxide would be did and calculated that it would increase the average temperature of the globe between one and a half and four and a half degrees Celsius. Now Arrhenius was Swedish. He thought global warming would be a good thing. The first person to suggest that it might be a bad thing and also to suggest that it might actually already be underway was the British steam engineer Guy Stewart Callendar, who, in 1938, published an article in the quarterly journal of the Royal Meteorological Society in which he published and compiled the existing data on carbon dioxide in the atmosphere, compared it with existing data on temperature and suggested that carbon dioxide was actually already beginning to creep up ever so slightly and that the temperature might be increasing, too. That was in 1938. But the following year, war broke out in Europe. Callendar went to work for the Royal Air Force on deicing planes and other militarily important things, and so he didn't come back to the issue for some time. One important uncertainty that was recognized as early as the 1930s was the competing effect of water vapor. So Tyndall had established that water vapor was an important greenhouse gas as well. As most of us know, there's much more water vapor in the atmosphere than carbon dioxide. So one question that was raised early on was why would small changes of CO2 have an impact on the atmosphere if carbon dioxide is swamped by the much greater quantities of water vapor? Some people suggested that therefore small changes in CO2 would not have much effect. This question was taken up and resolved by Gilbert Plass in the 1950s, who was one of the pioneers of upper atmosphere spectroscopy, one of the first people to use satellite measurements to measure the atmospheric constituents of the upper atmosphere. Plass resolved the absorption bands of water vapor and CO2 to a much greater degree than had ever before done before and showed that although there was some overlap in the absorption bands, there was also a very large area of nonoverlap suggesting that in fact additional carbon dioxide would have a detectable impact on the total greenhouse effect in the atmosphere. Plass's work had a big impact on these two men: Hans Suess and Roger Revelle, both oceanographers at the Scripps Institute of Oceanography in California where I first came across their work in the archives. In 1957, Revelle was working on the planning committee for the international geophysical year, thinking about what satellite and other measurements could be taken by during IGY that would answer scientific and important scientific questions. And one of these he thought was the issue of the question and the effect of carbon dioxide. And so in an article published in 1957, Suess and Ravelle suggested that by increasing the amount of carbon dioxide in the atmosphere by burning fossil fuels, that mankind was performing what they called a great geophysical experiment. That carbon dioxide had been stored in fossil fuels over hundreds of millions of years of geological time and large amounts of this carbon dioxide were now being returned to the atmosphere over the course of less than a century. And so they proposed that as part of the international geophysical year, scientists should begin to take systematic measurements of carbon dioxide to see if indeed it was increasing and, if so, what impact, if any, it was having on the atmosphere. This inventory, this monitoring of carbon dioxide, became the life's work of this man Charles David Keeling, also a professor at the University of California, work for which he won the National Medal of Science, awarded to him by President George W. Bush in the 2000s. In 1958, Dave Keeling began what became his life's work, the systematic measurement of carbon dioxide in the atmosphere. Within just a few years Dave Keeling concluded that his own data were already answering the question. That is to say that he discovered two things: First of all, a very dramatic seasonal effect of carbon dioxide associated with photosynthesis in the biosphere, but also a measurable, steady -- slow but steady increase in the total amount of carbon dioxide. So by 1965, Dave believed that his data did in fact show that CO2 was creeping up from about 315 parts per million in the atmosphere when he began to about 320 by 1965. This led him and Ravelle to write what, as far as I can tell, was the first warning or the first kind of alarm bell to be sounded by scientists to alert policymakers of what the possible economic, social and political impact of this could be. And in 1965, as part of a report of the President's Science Advisory Committee, Ravelle and Keeling wrote: By the year 2000 there will be about 25 percent more carbon dioxide in our atmosphere than are present and this will modify the heat balance of the atmosphere to such an extent that marked changes in climate could occur. They go on to talk about sea level rise and other effects that could result from increased global temperature. Now, it's often said that scientists -- that politicians never listen to scientists but at least one politician did. In 1965, Lyndon Johnson said, in a special message to Congress: This generation has altered the composition of the atmosphere on a global scale through a steady increase in carbon dioxide from the burning of fossil fuels. So that was 1965. So already decades ago scientists were alerting politicians to the fact that carbon dioxide was increasing; that it was a greenhouse gas, that it would be expected to affect the climate. And those changes in the climate would have a series of ramifying effects including sea level rise. But in 1965, President Johnson had a few other things to worry about and not much serious interest was generated in policy circles. That began to change a few years later, with a historical development that is probably of interest to people here at Microsoft, which was the rise of computer modeling of the earth's climate system. As all of you know, by the late 1960s and early '70s, there had been the development of fast digital computers which made it possible for the first time to build general circulation models that enabled scientists to study the earth's climate as a system. So up until now scientists had been working with computer models as part of numerical weather prediction, making 5-day forecasts. But for now for the first time, beginning to modify those computer codes to study the climate system. And to model the dynamics of the atmosphere in a quasi realistic way and to begin to consider long-term trends. And with this scientists like Suki Manabi [phonetic] and Kirk Brian [phonetic] at GFDL and other places began to revisit what they came to call the calendar question and to build state-of-the-art models which confirmed his and Arrhenius's earlier results. This began then to lead to the first serious discussion of this question in policy circles in the 1970s. A series of reports were issued by a number of different U.S. federal agencies, including NOA, the National Research Council, and the Jason Committee of the Department of Energy, all of which began to call attention to what were the likely or possible impacts of global climate change should be. This work was summarized in 1979 by the U.S. National Academy of Sciences who wrote: A plethora of studies from diverse sources indicates a consensus that climate changes will result from man's combustion of fossil fuels and changes in land use. So we see that already in 1979 there was a consensus among scientific experts that global warming was expected to occur. That it would happen. In effect, a consensus about a theoretical expectation. And there was also consensus that it was not a small concern. The National Research Council wrote: The close linkage between man's welfare and the climatic regime within which his society has evolved suggests that such climatic changes would have profound impacts on human society. And I find this very interesting, because even today we're still grappling with this issue and grappling with people who say: Oh, well, a degree two or three here, there, what's the big deal. But the scientists, even in the 1970s, were trying to point out that human civilization had evolved over a very short period of time. I mean, most of everything we call civilization has evolved within the last 10 to 12,000 years, since the end of the last glacial maxim in a relatively narrow window of average global temperature. So there was agreement about experts that climate change would be expected to occur, and there was an agreement amongst experts that it would matter. The big question about which there was not yet agreement was when. When would these changes occur? Most scientists thought that they were still pretty far away. That detectible changes would not occur until the 21st century. If you read the scientific literature reports from this period, dates like 2000, 2010, 2030, 2050 are being bandied about. So the surprising result was when detectible changes, or changes become detectible, only six years later. When NASA climate modeler Jim Hansen and his team at the Guided Institute for Space Studies concluded that the human fingerprint, the anthropogenic signal, had in fact already become detectible in their data. Hansen testified to this in the summer of 1998 as heat waves were racking the American Midwest, declaring he and his team were 99 percent certain that climate change driven by human facts by anthropogenic global warming was now detectible. It was this emerging and data, disturbing data that climate change was happening more rapidly than scientists had imagined that led in part to the creation of the IPCC in 1988. But it also led to something else. It led to the emergence of a politically motivated campaign to challenge that scientific consensus, to challenge the scientific data behind Hansen and others' conclusions and to cast doubt upon that science. The campaign focused on the claim that the science was unsettled, that there wasn't a consensus amongst experts; that scientists were still arguing the point, and therefore it would be premature for governments to act to intervene. As a historian, I'm interested in origins, and it turns out that the origins of this claim can actually be traced back to a surprisingly small number of people. Now, today, doubt about climate science is promoted in many quarters. We hear it promoted on Fox News. We see it promoted all over the Internet. Many think tanks such as the Cato Institute, The Heritage Foundation, The Heartland Foundation, The Competitive Enterprise Institute, there's a long list of people who now promote doubt about climate science. But one of the most important, one of the most persistent voices challenging climate science, going back to 1988, going back to this period when the scientific evidence first really came together, is the George C. Marshall Institute, a think tank in Washington D.C. Since the late 1980s, The Marshall Institute has either denied the reality of climate change or insisted if there is climate change that is not caused by human activities. So where did The Marshall Institute come from? And why do they promote doubt about peer reviewed climate science? Well, The Marshall Institute was founded by three men. All physicists, all nuclear physicists or rocket scientists who had built their careers in the Cold War working on American nuclear weapons and rocketry programs. On the left, Robert Jastrow, the original founder of the Marshall Institute, an astrophysicist, head of The Goddard Institute for Space Studies who had been very active in helping to develop the rocketry behind the Apollo program. On the right, William Nierenberg, long-time director of Scripps Institute of Oceanography, a nuclear physicist who had worked on isotope separation during the Manhattan Project and subsequently became involved in many Navy-funded projects related to the Cold War, including the accurate location of submarines for submarine launched ballistic missiles. In the center, Frederick Seitz, a solid state physicist who had worked with Eugene Vigner, who is considered one of the fathers of the atomic bomb; the man who helped convince Albert Einstein to write his famous letter to President Roosevelt advocating the building of the bomb, who rose to prominence in 1950s and became president of the U.S. National Academy of Sciences and then president of the Rockefeller University. These three men had known each other for many years. They had served on many high level scientific advisory committees. And in the early 1980s they found themselves working together on an advisory panel to the Reagan Administration on the question of strategic defense, or what most of us know as of Star Wars. As many of you know, SDI was highly controversial among scientists because it was a departure from the Cold War doctrine of mutual assured destruction. Because if the United States believed that we had an effective missile defense shield, then we might be tempted to launch a preemptive first strike against the Soviet Union. And so for this, and a number of other reasons, both political and technical, American scientists mobilized very actively against SDI. Over 6500 American scientists and engineers, including many computer scientists, signed a petition declaring a boycott of the SDI program. Jastrow, Nierenberg and Seitz all supported SDI. They all considered it necessary for American defense. And so in 1984, they created The Marshall Institute to defend SDI against their colleagues's opposition and to promote the continued importance of science and technology in national defense, in part by insisting on the reality of Soviet strength and of U.S. weakness. I don't have time to give you a lot of examples of the kinds of things they did. But they organized workshops for journalists and congressional staffers. They wrote white papers, articles, letters to editors; and my favorite one is this article published in National Review in 1987: America has five years left. That's one scientific prediction that did not come true. Now, at this time, Fred Seitz had retired from his position as president of the Rockefeller University, and he had taken on one last job in his retirement years, working as a consultant to the RJ Reynolds Tobacco Corporation. We know from tobacco litigation and from the work of historians like Robert Proctor and Allen Brant that the principal strategy that the tobacco industry used to defend its product against the scientific evidence of the harms of tobacco was doubt mongering, or what we call in the book the tobacco strategy. To insist that the science was unsettled, to insist that there was debate, continuing debate in the scientific community about harms from tobacco, and therefore it would be premature for the government to act or discourage or control tobacco use. In 1989, these two stories came together. The Cold War ended rather more abruptly than anyone had imagined would occur. The Berlin Wall came down. The Soviet Union began to break apart. So you might have thought that these cold warriors would have been happy, that their life's work had achieved the goal they wanted, the collapse of the Soviet and vindication and victory of the west. But instead of being happy, instead of retiring contentedly and playing golf, our cold warriors kept fighting. But they had to find a new enemy to fight. And that new enemy was what they called environmental extremism. The exaggeration of environmental threats or what they consider to be the exaggeration of environmental threats by people with a left wing agenda. And they applied the tobacco strategy that Fred Seitz had learned working for RJ Reynolds, to insist that the science was unsettled. Doubt is our product, ran the infamous memo written by one tobacco industry executive in 1969; since it's the best means of competing with the body of fact that exists in the minds of the general public. One of the things that the tobacco industry recognized early on was that if doubt was their product, they needed people to sell doubt. And they realized that if a tobacco industry executive stood up in public and said, well, we're not really sure tobacco is harmful, most of us would not find that highly credible. And certainly journalists would not find that highly credible. But if a scientist said it, and if particularly a prominent scientist, a former president of the U.S. National Academy of Sciences said it, well, that was a different matter. So a significant part of the tobacco strategy, what they sometimes referred to as Project White Coat was to recruit prominent scientists, the more prominent the better, to sell the message of doubt. Now, they didn't have to be doctors. They didn't have to be oncologists, they didn't have to be epidemiologists, because one of the things that tobacco industry found was that the public didn't really know the difference between oncology and atmospheric chemists, and journalists never asked. Journalists never said what actually is your specialty. Of course we see this going on even today. So the book, "Merchants of Doubt" is the story about the scientists who supplied doubt. The scientists who were recruited by the tobacco industry and others to supply doubt but not just about the harms of tobacco, although that's where the story begins, but a story that runs through a whole series of issues then, a series of issues about which these men became serial contrarians, in case after case after case, challenging the dominant scientific view and supplying doubt about it over the course of the question of the threat of nuclear winter and the efficacy of SDI, the reality of acid rain, and severity of the ozone hole, and most recently, of course, the biggest issue of all of these, the human drivers of global warming. And in the book we also have a discussion of a kind of revisionist attack that is going on today over the question of the science related to the pesticide DTD. In the book we tell the story of how these prominent physicists cast doubt on the science related to each and every one of these issues, how in every single case the playbook was the same. In case after case after case, even for science that was totally different and totally unrelated, they insisted that the science was too uncertain to justify government action. Now, to learn how they do it, you'll have to buy the book. What I want to talk about today is what my colleague Eric Conway and I found to be in a way the most perplexing part of the book and the part of the story that we felt most motivated to try to understand, which was why they did it. Why would prominent and distinguished scientists like Frederick Seitz, why would they challenge the work of their own colleagues? Why would they reject data published in the very journals they themselves had published their own scientific work during their own scientific careers? Why would they doubt the work of people that they had hired in their own institutions as was the case for Robert Jastrow? And also why this doubt mongering campaign, why it worked, why it gained so much traction, especially on the conservative or Republican side of the American political spectrum as we see today with so many Republican leaders rejecting the scientific evidence? And then helping then to explain why this issue became so politically polarized. So, again, I don't have time to go into all the details of the book. So this is a kind of short answer version. But the short answer is actually ideology. It's about belief systems and belief structures. When we started this work, almost everyone we spoke to thought we were going to tell the story of a simple story of corruption, of people doing this for money, and it's really important to point out that at no point during this story did we ever find any evidence that any of the key players were predominantly motivated by money. But, rather, we found abundant evidence that they were deeply motivated by their political beliefs. And, in particular, by the belief that George Soros has termed free market fundamentalism. That is to say a kind of abiding faith, a kind of overwhelming faith in the power of free markets. In the book we talk about this, and I think the best way to think about free market fundamentalism and its role in American politics over the last 20, 30 years is to understand it as sort of an end member of a spectrum of views that are broadly categorized as modern neoliberalism. This is a set of views that have been very predominant in the last 30 years focused on the importance or the power or efficacy of deregulation and releasing the so-called magic of the marketplace. It came to prominence in the early 1980s under Margaret Thatcher in the United Kingdom and Ronald Reagan here in the United States. But it wasn't just conservatives and Republicans that promoted neoliberalism, it was also promoted in the 1990s the so-called Washington consensus led by our democratic President Bill Clinton and UK Labor Leader Tony Blair. It has also been promoted heavily by the famous head of the Fed, Allen Greenspan, who served five different presidents, both Republican and Democratic. And indeed I think it's fair to say that right up until the global financial collapse over the last few years, there has been, in political and economic circles, a bipartisan consensus on the virtues of deregulation. (Latin). Now, where did this all come from? Well, among conservative economists in the United States, the principal inspiration for this comes from the Chicago economist Milton Friedman, who published a seminal work quite worth reading in 1962 called "Capitalism and Freedom." The crux of the argument is summarized by the title. Friedman argued that capitalism and freedom are two sides of the same coin; that they have to go together; that they inevitably go together, because without capitalism you won't have freedom and without freedom you can't have capitalism. Why? He argued if state governments attempt to control the economy, the only way they can control economy is to control the people who are, the citizens who are the actors in those economies. So if you allow for the role of the government in the marketplace, it's only a matter of time before the government will begin to control other aspects of your life like civic, political and religious freedom. And, therefore, the defense of free markets for Friedman was a defense of freedom. Without which we would be on a slippery slope to tyranny. In "Capitalism and Freedom," which, by the way, was published in 1962, the very coldest year of the Cold War, at the time of the Cuban missile crisis, Friedman acknowledges his debt to his intellectual inspiration, the Austrian neoliberal economist Friedrich von Hayek, who in 1944 published a deeply influential book called "The Road to Serfdom" in which he essentially argued the same point, but not just about Soviet-style totalitarianism but even more liberal and modest forms of western European social democracy, which he thought would put us on a slippery slope towards the road to serfdom. Now the contrarians in our story took this argument even further, arguing that environmentalism was the slippery slope to socialism the path to creeping communism. Why? Well if you look at it because environmentalists in general particularly in the last 30 years have tended to argue for the importance of government regulation, and they argue that from regulation of acid rain or secondhand smoke, it was only a small step towards government control more generally. This idea was articulated in many of their writings but perhaps most clearly by a fourth physicist who joins the story in the 1980s, a man by the name of S. Fred Singer, whose personal biography was almost identical to the other three. He was also a Cold War physicist. In fact, he was the proverbial rocket scientist, having worked on some of the earliest American rocket launches, and also involved in repeated campaigns to challenge scientific evidence related to acid rain, the ozone hole, and even continuing to this day, just last week, he launched a new attack on the scientific evidence related to global warming. Now, I mentioned that Seitz had worked for the RJ Reynolds Tobacco Company. In the early 1990s we find Fred Singer working with Phillip Morris to attack the Environmental Protection Agency over the issue of secondhand smoke. In 1993, Singer and a lawyer named Ken Jeffries wrote a wrote called: EPA and the Science of Environmental Tobacco Smoke. It was published -- Jeffries was a lawyer affiliated with the Cato Institute and The Competitive Enterprise Institute, not a scientist. Singer was a physicist, not an oncologist, not an epidemiologist. They wrote this report. It was published by a fourth think tank, a group called The Alexis de Tocqueville Institute. If you look at the documentation surrounding this report, which Eric and I have done, you find that funding for this came from the tobacco institute which was a research center set up by the tobacco industry. So here you have in a nutshell, tells a whole other part of the story that we tell in the book about the way in which the tobacco industry and later also the fossil fuel industry funneled money into supposedly independent think tanks like the Alexis de Tocqueville to write reports supporting the positions that were in fact the position of the tobacco industry. Some of the memos we found even have things that say things like: We have to be sure to cover the Phillip Morris fingerprints on this one, or we don't want any Phillip Morris fingerprints on this one. So they create a whole network of think tanks. In the book we talk about this, Eric and I counted 25 different think tanks we've been able to identify that have been promoted doubt mongering about tobacco, global warming and other issues, all of whom have received funding either from the tobacco industry or fossil fuel industry, the chemical industry, all who claim to be independent and nonpartisan, all whose activities are tax deductible because they are nonprofit and nonpartisan. Okay. So why were they going after the EPA at this point? Well, there's a little sideline, I love to tell the story, because it's one of the few times we find the tobacco industry making a tactical mistake. The guys who work for the tobacco industry were incredibly smart, had armies of really smart, really hardworking lawyers. They rarely made big mistakes but they did make one here. The tobacco industry was very sensitive about language. They were always talking about what they should call things. And they decided, in the early 1990s, they didn't like the term "secondhand smoke." Because they reckoned that Americans didn't like secondhand things. So they decided they would call it "environmental tobacco smoke" instead. Thought "environmental" sounds kind of nice well, the only problem was that this invited the scrutiny of the Environmental Protection Agency. So in 1992 the Environmental Protection Agency reviewed the issue and declared secondhand smoke to be a Class A or proven carcinogen. And some of you may know about Class A carcinogens because, of course, World Health Organization has a whole set of Class A, B, C proven, possible probable and as we've all heard a lot of discussion about cell phones now in this whole category. But Class A is the highest level of demonstrated, robust independent, replicable peer reviewed data and this result was affirmed independently by the U.S. Surgeon General. Indeed, the evidence was supported by over 10,000 different independent peer reviewed studies in the United States, Japan, Canada, Australia, Germany and elsewhere. So why would a rocket scientist challenge these data? Indeed, why would any scientist challenge these data? Well, the great thing about being a historian is how often people answer these questions themselves. You don't have to speculate, because often people tell you in their own words. And Fred Singer did exactly that. On page 2 of this report he wrote: If we do not carefully delineate the government's role in regulating dangers, there's essentially no limit to how much government can control our lives. So here you see it, the road to serfdom, the slippery slope. If we let government tell us whether or not we can smoke, it's only a matter of time before they'll control other things, including, of course, the economy. And so then we begin to see the Milton Friedman argument emerging here as well. So in 1996, after the second assessment report of the IPCC, Fred Seitz, who was a physicist, not an economist, wrote a report in the Wall Street Journal in which he alleged that: IPCC reports are often called a consensus view. But if they lead to carbon taxes and restraints on economic growth, they will almost certainly have a destructive impact on the economies of the world. So the governments will control our lives. Personally they'll control the economies and we'll be on a slippery slope both to serfdom and economic collapse. And Frank Luntz made a similar point in the Wall Street Journal. This time in 2003, before his conversion. So this is after the third assessment report of the IPCC Luntz writes: Once Republicans can see that greenhouse gasses must be controlled, it will only be a matter of time before they end up endorsing more economically damaging regulation. So you see this idea that Republicans can't concede the science because if they concede the science, well, then we'll have to endorse regulation. And most recently we see this story continuing just a few weeks ago, some of you probably know, that Republican presidential candidate Mitt Romney broke with many in his party on Friday, this is from CBS, when he said that he believes that humans have contributed to global warming. So Romney is the only one of the major Republican candidates, or may be only one of the Republican candidates, interested in being the next President of the United States, who are willing to say in public they accept the scientific evidence of anthropogenic climate change. And when Romney made this announcement in Hanover, New Hampshire, Newt Gingrich said the push to address climate change is the newest excuse to take control of our lives by left wing intellectuals. So we see this throughout the writings of contrarians, assertions that environmentalists and also, by implication, scientists working on environmental issues have a hidden agenda to control our lives. It's a hidden agenda that is anti-business, anti-free market and anti-technology. And we see often the allegations sometimes the overt accusation that environmentalists are in fact socialists in disguise. They refer to environmentalists as watermelons: Green on the outside, red on the inside. George Will, who writes for the Washington Post, not generally considered to be a right wing newspaper, has accused environmentalism of being a green tree with red roots. And Senator James Inhofe of Oklahoma who has threatened to indict climate scientists for conspiracy to lie so Congress, has accused the scientists of being part of the liberal conspiracy to bring down global capitalism, to which I reply that liberals should be so organized. Here's what Fred Singer had to say about this anti-business agenda, the hidden agenda. In 1989, discussing the ozone hole, Fred Singer wrote: And then there are those probably with hidden agendas of their own, not just to save the environment but to change our economic system. Some of these coercive utopians are socialists. Some are technology-hating Luddites. Most have a great desire to regulate on as large a scale as possible. You see here repeated the accusation these people are socialists, communists, they hate technology and they want to control our lives. He continued a couple of years later: More dangerous are those who have a hidden political agenda most often oriented against business, the free market and the capitalistic system. Of course, after the collapse of socialism, it is no longer fashionable to argue for state ownership of industrial concerns. The alternative is to control private firms by regulating every step of every manufacturing process. So what we see in all this repeatedly over and over again is that the debate is not about the science. We do not actually see Fred Seitz, Fred Singer, Robert Jastrow, Bill Nierenberg, raising principal concerns about the quality, quantity or diversity of the data. We don't see them raising principal concerns about the peer reviewed process. Lately we have seen people claiming to make those claims. What we see them raising concerns about are about governance. And more specifically about regulation. And we see them raising these concerns in the context of an ideological commitment to laissez-faire economics, a belief in the inextricable link between political and economic freedom, a kind of deep hostility to regulation as a form of creeping communism, hostility that was born and nurtured and hardened in the Cold War. Now, of course many of these claims are a matter of opinion but not all of them are. And as a historian I'm always interested in things that people say, people assert that are demonstrably incorrect, if you know anything about history. There are many such claims that we address in the book, but to me one that's most ironic is the claim that environmentalism is a green tree with red roots. Because we know a lot about the history of the environmental movement in the United States, many wonderful books written about this question. The origins of the U.S. environmental movement are not to be found in left wing politics, not to be found in the labor movement, the international workers of the world, the socialist party, the communist party, but in the progressive republicanism of Teddy Roosevelt, Gifford Pinshow [phonetic] and as I like to say that famous communist John D. Rockefeller. Right up until the 1960s there was a bipartisan consensus in the United States about the importance of land preservation and environmental protection. So much so that when the Wilderness Act of 1964 began to designate American lands that would be areas where man is a visitor and does not remain, it passed the U.S. Senate by a vote of 73 to 12. And the House of Representatives by a vote of 373 to 1. In the 1970s, the Environmental Protection Agency, so hated by the tobacco industry and so vilified today by Republicans in Congress and the utilities industry was created by the Republican President Richard Nixon who signed into law the key pieces of environmental legislation that remain the backbone of environmental protection today, including the Clean Air Act, which is the basis under which the Supreme Court has found that the EPA does in fact have legal authority to regulate carbon dioxide as a pollutant. But things began to change in the 1980s. They began to change both scientifically and politically. Scientifically, they began to change because scientists, not environmentalists, but scientists working on the natural world began to discover evidence of serious problems like acid rain, the ozone hole and global warming, problems that seemed to demand some kind of government action, problems that seemed to many people to demand some kind of government regulation. And these issues emerged, and I would say that this is the kind of historical tragedy of the story, a kind of just terrible bad luck, that the scientific evidence of these issues began to coalesce just as the, in the historical moment when the Reagan Administration was arguing for less government and less regulation, precisely as advocated by Milton Friedman. Here we see Milton Friedman shaking hands with the president at the White House. And this I would argue, then, and we do argue in the book, put the Reagan Administration, and later the entire neoliberal consensus on a collision course with science, indeed on a collision course with our future. Now, Ronald Reagan may have had a point. Government regulation is not the solution to every problem. And some environmentalists are socialists. Moreover, as a historian of science I'm quite comfortable in saying that the cutting edge of science is always unsettled. There is always uncertainty in science. And there's always room for reasonable doubt. But from the point of view of public policy, from the point of view of making decisions about important issues that can affect our health, our safety, our well-being and maybe trillions of dollars of infrastructure, the question becomes what's reasonable? History shows that the rejection of the scientific evidence regarding DTD, acid rain the ozone hole and secondhand smoke wasn't reasonable. It wasn't based on reasonable scientific doubt. In fact, it wasn't based on scientific doubt at all. It was based on the desire to avoid government regulation of the products and activities that created those problems because of the anxiety that those regulations would lead to other unsatisfactory or undesirable things. History also shows that DTD, nuclear winter acid rain and the harms of tobacco were all real problems needing real solutions. One of the strangest things that I often hear contrarians say, I sometimes get it in talks, sometimes get this on the radio, people will say: I'm old enough to remember acid rain and the ozone hole. So I just don't believe this latest anxiety about global warming. But I want to say: Wait a second, we were right about acid rain, scientists was right about acid rain, there really was acid rain. It really did kill forests and fish and there was an ozone hole. We fixed it because we did something about it, we listened to the scientists. It's like a weird nonsequitur. Like I don't know how acid rain and the ozone hole become evidence that global warming isn't real. These were all real problems, problems in which science has been now confirmed many times over. These were all issues where the scientists got it right and the doubt mongerers got it wrong. Finally, and perhaps most important as we move forward to try to address the problem of global warming, history also shows us that free market capitalism, like any human institution, has its limits. You don't have to be a communist or socialist to recognize the problem that our economists colleagues call negative externalities. These are costs that accrue to people who do not reap the benefits of the activities that generated them. If you pick up any introductory textbook in economics you find that environmental damage is the textbook case of the negative externality, a cost that's not reflected in the market price of that good or service. Indeed, this is the common thread that unites the diverse science challenged by the Merchants of Doubt that in every case it involved a market failure. A case where the fair market did not reflect these true costs. They were all examples of behaviors that generated large external costs and therefore provided the possible warrant for government intervention in the marketplace to replace those market failures. Nicholas Stern, the former chief economist of The World Bank has called anthropogenic global warming the greatest and widest ranging marketing failure ever seen. So it's not surprising then, if we look at this larger history, that environmentalists, Europeans, and those on the left of the spectrum, were quick to accept their reality. People who accepted the idea that capitalism maybe had some limits weren't troubled by evidence that that was true. But people who believed deeply in the power of free markets were slower to accept the evidence. The conservative jurist Richard Posner has argued that behavior that generates large external costs provides an abdication for government regulations. I don't know if you're familiar with Posner's recent book, "A Failure of Capitalism" but he's a conservative who has become interested in the failures of regulation related to the global financial crisis. He's exploring this issue of how do you decide when it's appropriate for the government to intervene in a marketplace and when it's not. And his argument is that when you see evidence of large external costs, that's when you ought to be talking about government regulation. But the point of this then is how we feel about regulation. How we feel about the idea of unregulated markets is going to affect how we feel about those behaviors, whether it's smoking or burning fossil fuels. Cognitive science has shown us over and over again that we are all more likely to accept evidence consistent with our pre-existing world view. But as Posner notes: A rational decision-maker starts with a prior probability but adjusts that probability as new evidence comes to his attention. History tells us that scientists have known for a very long time, for more than a century, that global warming could occur from the burning of fossil fuels. And for more than 20 years now evidence has been mounting that it is indeed occurring, evidence that our scientists now tell us is, quote, unequivocal. And, of course, one other point that should not be ignored is that the energy sector is not a free market. I think this is the other second really big irony in this whole story. The World Bank recently completed a study looking at the question of what subsidies, global subsidies to fossil fuel production look like worldwide. The latest year for which they have data is 2008. As of 2008, global subsidies fossil fuel consumption were $700 billion a year. We can compare that with the troubled assets recovery program, also known as the bank bailout, which was also $700 billion. So we're bailing out the fossil fuel industry every year. This is a TARP per year for the fossil fuel industry. So we might ask why we do that and why the defenders of free market capitalism are not troubled by this massive government intervention in the marketplace. So to conclude: The industrial revolution brought the developed world 150 years of unprecedented prosperity, a free lunch of historic proportions. And, by and large, that prosperity has been a good thing. But as the economists tell us, there's no free lunch. The prosperity we enjoyed was not actually free. Global warming is the bill for that prosperity, a bill that has now come due. And as Kim Stanley Robinson has pointed out, the invisible hand never picks up the check. Thank you very much. [applause] >> Kirsten Wiley: Time for questions if anyone has any. >> Naomi Oreskes: Sure. >>: Have you encountered any link between the people and organizations discussed in this book and the people who released the so-called Climategate e-mails? >> Naomi Oreskes: We did. We didn't have time to write about it because that all happened after the book came out. But the Cato Institute and The Heartland Institute, who talked about in the bock have been very involved. We don't know who stole the e-mails, the police have still not figured that out, Scotland Yard has not released any information on that. But we do know the Cato Institute and Heartland Institute have heavily funded defended the dissemination of the accusations surrounding those stolen e-mails. >>: I gotta say I found the talk very depressing. >> Naomi Oreskes: Sorry about that. Well, if we had more time we could go out for a drink. >>: When things become ideologically based, seems like it's almost impossible to change peoples' mind. Besides one of the Republican strategist, do you have hopeful stories that have been on the doubter's side that have woken up and said I was wrong to think ->> Naomi Oreskes: Actually we do. And one of the things that's really depressing about the story is that it kind of looked like that was happening in the mid-2000s, so it wasn't just -- Newt Gingrich made a statement that he accepted -- I had a longer version of this talk where I had actually a whole set of these people. And there were many people in the mid-2000s. So we're saying, okay, we do have evidence of this. But then it kind of went backwards after the election of President Obama, and now it seems that the Republican party has hardened its position against the science. That's very worrisome. I think you're right. Part of what's the heartbreak of the story, the way it's become so politically polarized that you can't actually discuss the data with a lot of people. And I get this all the time, and often even when I talk, there will be someone in the audience who says I've been on the Internet, I've researched this and those data are wrong. It's like, well, who is it that's telling you the data are wrong? I mean it's the Cato Institute, or it's not NOA, it's not NASA. It's not the U.S. Geological Survey it's not Lawrence Livermore National Laboratory. The weirdest thing about this for me is that I'm going in November to talk to the Department of Defense Environmental Research Symposium. In the military, the military not only accepts the evidence is true but is preparing for it. The Navy has a Navy task force on climate change that is looking at the question of how sea level rise and other climate changes are going to affect Navy operations. So it's a bit of a mystery to me why the people who are so entrenched in this issue aren't moved by the fact that our admirals, and our generals take this seriously. So I think it just shows how incredibly entrenched this thing has become now and how much damage has been done to the state of the political debate in America. >>: So your position of a doubter, it's sort of a logical gap, like you can propose the argument that regulation hurts the economy. And that's fine. But then what do you do about an activity that is still damaging? >> Naomi Oreskes: Right. >>: Are they expecting the free market to, eventually the economies will change and will do something that's not damaging anymore? What is the solution to like the health hazard? >> Naomi Oreskes: There's a couple of different things. So I mean early on in the debate, say one of the arguments that the tobacco industry made was that it's a free country and it's for you to decide for yourself. You're a grown-up; if you want to smoke, it's your decision. And on some level that's a position that I'm personally sympathetic to. But if and only if we have good information to make those decisions about. So, again, another irony of this story, and of course this was one of Adam Smith's original principle, that for the invisible hand to work, people had to have perfect information. We know we never have perfect information, but we hope we could at least have pretty decent information. The tobacco industry did everything possible to make sure that we didn't have good information. So there's a kind of deep hypocrisy about that. It's also why the secondhand smoke debate became so furious. And some of the most nefarious things we talk about in the story happened not in the early debate about grownups smoking, but in the debate over secondhand smoke. Because, of course, the tobacco industry argument that it's a free country, you're a grownup, you can decide, breaks down over secondhand smoke. Because if my smoking is killing you, killing my bartender, killing my flight attendant, killing my children, which is when it really got ugly, that's a whole different matter. So they went really ballistic. There's a whole -- I have a whole other set of slides about secondhand smoke and Sudden Infant Death Syndrome, which even today many pediatricians don't know that Sudden Infant Death Syndrome, that secondhand smoke is a causal factor in Sudden Infant Death Syndrome. Many pediatricians don't even know that because the tobacco industry went to enormous lengths to suppress that data. So that's kind of one contradiction in hypocrisy in the story. But the other part of it is -- so there are kind of two nonhypocritical responses that people made. So one response was to say the free market will do it. That if you just -- in fact, this is kind of the argument that the Cato Institute makes, that part of the reason why you don't want the government intervening is because if the government intervenes it distorts the market forces and it actually prevents the market from responding in the way that it needs to. And that's a very attractive argument, I think, and I think it would be fantastic if it were true. The problem is the historical evidence just doesn't support it. We've known about climate change now arguably for at least 20 years, and yet we aren't really making the technological transformation to a low carbon energy that we need. So it is a market failure because the market isn't doing what it needs to do. Now, there's lots of arguments about why that might be. But most economists say that it is because of the negative externality problem; that the price doesn't reflect the true cost. So the solution then is to put a price on carbon. So then you get two solutions, right? Carbon taxes or cap and trade systems. So yet a fourth or fifth or sixth irony of this story is that, so Republicans are extremely hostile to cap and trade now, and it was Republicans in the House that killed the cap and trade legislation last summer, but it was actually Republicans and conservative economists who first developed the concept of cap and trade, because cap and trade was supposed to be a market-based system. It was supposed to invoke the power of the marketplace, put a price on carbon, we'll let you trade it in the marketplace, freely trade it, businesses can decide for themselves what the most effective way to do this is, have flexibility and the first Bush administration supported cap and trade for acid rain, and in fact it was effective in the Midwest and in Canada to control acid emissions. So the turning against cap and trade by the Republicans in the United States to me is deeply cynical and deeply depressing, because, you know, it was supposed to be a market-based mechanism. Now we have this irony that some Republicans are now saying we should have a carbon tax -- which is ironic beyond belief. Yet I find myself wanting to support them and say, well, great, let's have a carbon tax, because actually that would be a simpler, in my opinion, according to many economists, a carbon tax is a much simpler way of doing it than a cap and trade system, but of course if we go back to the 1980s and '90s some of us are old enough to remember that Republicans vilified Al Gore over the carbon tax question, and we know that most Republicans really don't like taxes. So it's a very difficult issue. I think that in my mind honest economists do recognize that a carbon tax is probably the simplest and most efficient way to solve the problem economically. The question is whether you can make it politically acceptable. Yeah. >>: I'll have to dispute your last statement. Economists wouldn't say tax is most efficient, they would say cap and trade is most efficient, opposing externalities show that. The problem is that you have to assign somehow the correct amount that was pretty well done on acid rain and sulfur dioxides, cap and trade worked well there. You also have to assign the initial property rights. And that's an equity issue it's not an efficiency issue. So I think you just misstated what -- >> Naomi Oreskes: Okay, I mean, there's disagreement about that. >>: It's not disagreement, tax is not as efficient as imposing cap and trade. >> Naomi Oreskes: A cap is not as efficient ->>: A cap and trade. >> Naomi Oreskes: Is more efficient. Okay. I'm not an economist. I'm only going based on what I know from the economists I've talked to. I have not studied this in great detail. I have gotten the impression that most of my economic colleagues and academic economic departments do think that a carbon tax would be a simpler and more efficient mechanism. I might be wrong about that. So if you know more about it than I do I respect that. My own view not being an expert is that I think we have evidence that either one might work under the right circumstances, but it's sort of a political choice, which do you think is more acceptable in the political circumstances you have. But I will defer to you on that. >>: Follow-up? >> Naomi Oreskes: Sure, go ahead. >>: Have you looked at applying your analysis to nuclear power? >> Naomi Oreskes: In what particular way? >>: In the particular way that there's a trade-off for carbon emissions? >> Naomi Oreskes: You know, I've thought about it a little bit. I used to work in the mining industry, and I worked in uranium exploration, so I at one point knew a lot about the nuclear power industry. I haven't really studied it much in recent years. I've done a little reading about it. But I haven't really done anything extensive, and I certainly don't consider myself an expert on it. So my opinion would just be another person's opinion. >>: You talked [inaudible] talked about science and politics. I mean, good calories and bad calories. I mean, what's your take on that. >> Naomi Oreskes: I'm sorry, on good terrorist/bad terrorist? >>: Good calories and bad calories. >>: [inaudible] calories? >>: Calories by David Tau. >> Naomi Oreskes: I don't think I'm understanding the question. >>: Book is called "Good Calories/Bad Calories." >> Naomi Oreskes: It's a book, I'm not familiar with that. I'm sorry. >>: So looking at this little comic up here, I'm wondering what the impact of kind of population growth in the developing countries is going to have on this stuff that we can do as a developed nation to try and mitigate, right? Because I'm just worried that we can put -- I think we should do everything we can, but then we've got this huge population growth occurring that we can't stop. >> Naomi Oreskes: And I get asked that question a lot, but I think it's really important to note a couple of things about population growth. The vast majority of the greenhouse gasses in the world are not being produced by developing nations. They're still being produced by the industrialized nations, the United States, Germany, Japan and the United Kingdom Europe and China as an emerging nation what the industrialized world does is the most important thing. The lion's share of both the greenhouse gasses that are produced per capita and greenhouse gasses, the integrated greenhouse gasses that have been produced up to date, still come from the industrialized nations, the United States and Europe. So it still really matters what we do. China, of course, is the next most important because China, China has now exceeded the United States in per annum emissions, although not in per capita. But obviously what we do matters because if we don't act, China says why should we act. It's a little bit of a prisoner's dilemma, why should we act if the United States won't act, the United States says why should we act if China won't act. So somebody's got to take this first step and the United States does still have the biggest responsibility for the total CO2 and other greenhouse gasses in the atmosphere. The developing nations, the really poor nations, are a very, very tiny fraction of the total greenhouse gas footprint and probably will remain a very small fraction for quite a bit of time. So the population thing is tricky because most of the population growth in the world is not where most of the greenhouse gas production takes place. So I think the people who focus on population growth as the main driver actually don't think that's right. It's not population growth that's the driver. It's consumption growth. And total consumption. And that's still mostly in the western world. Now, of course, eventually that will change, but I know Neil Encarr [phonetic] has done some interesting modeling on this where he looks how that might change in the future, but he still comes to the conclusion that for the foreseeable future, up until the end of the 21st century, it's still 60 percent of the way of greenhouse gas emissions is going to come from the industrialized nations, from greenhouse gasses consumption, not population growth. So ultimately population growth does become part of the story as countries develop and presumably use more energy. But then by that point the other issue is, of course, leadership. That I mean I'm not a Luddite, I'm pro technology, I think if there's any solution to this problem, it has to be technological. Then the question becomes who is going to develop that technology, who is going to sell it, who is going to make money off it, who is going to create jobs, and there I think that whoever is out in front in developing efficient solar energy, efficient wind power, other algae biofuels or whatever it is, those countries will make money. Those countries will have a better balance of trade, those countries will sell that technology to other countries and those countries will develop leadership in the world if they then help the poorer nations develop by using these low carbon technologies. And one of the things I worry about, and again another irony or paradox of the story, so China is moving forward very aggressively with solar and wind technology, much more aggressively than the United States. What message does it send to the world if China becomes the leader on this issue, if an authoritarian country, which China still is, is able to actual offer remedies to this problem and the liberal democracies prove paralyzed, what message does that send to the developing world? So I think it's enormously important what the United States does, and despite all the reasons in my own work to be pessimistic, I still remain optimistic that ultimately we will offer both political and technological leadership on this issue. But I have no evidence to support that optimism. And that might be a good place to stop. I think we're out of time. >> Kirsten Wiley: Thank you. [applause]
