Assessing the Accuracy of Cable News
Coverage of Climate Science
Aaron Huertas
Rachel Kriegsman
April 2014

Our national debate about climate policy is broken. Too often, policy makers and other public figures make misleading statements that question whether climate change is humaninduced—or is even occurring at all—rather than debating whether and how to respond to risks from climate change that scientists have identified. Media outlets can do more to foster a fact-based conversation about climate change and policies designed to address it. Such conversations can help audiences base their positions on climate policy on accurate climate science, as well as their varying political beliefs, attitudes, and values.
To gauge how accurately elite media outlets inform audiences on climate science, we analyzed climate science coverage across the three major cable news networks: Cable News Network (CNN), Fox News Channel, and MSNBC. We found that the accuracy of this coverage varied significantly across networks. In
2013, 70 percent of climate-science-related segments on CNN were accurate,
28 percent of Fox News Channel segments were accurate, and 92 percent of such segments on MSNBC were accurate.
In this report, we discuss social science related to public perceptions of physical science, provide a brief overview of our methods (covered in more detail in the online appendix at www.ucsusa.org/scienceorspin), present results for each network, and discuss each network’s coverage. We present recommendations and suggestions for climate science coverage that could serve to improve the scientific accuracy of public discussions about potential responses to climate change.

    Al Gore is a politician and environmentalist that gave his speech “Climate Emergency” at Yale School of Forestry in 2004. He also presented it during the presidential campaign that same year. He argues that the Earth’s environment is in fact vulnerable, and that humans have a big impact on it. In his speech he uses scientific facts, statistics, maps, and graphs to demonstrate. Gore explains why he used the title “Climate Emergency”, “it is intended to convey what it conveys- that this is a crisis with an unusual sense of urgency attached to it, and we should see it as an emergency. The fact that we don’t, or that most people don’t is part of what I want to cover here” (Gore, 861)…

    In March of 1992, Dr. Richard Sanford wrote an outspoken paper opposing the claims of the global warming hysteria of recent time. Sanford discusses how people accept global warming theories as scientific fact without questioning their validity. I can honestly say that I was one of these people who agreed with the media's interpretation of these theories. After reviewing the pro global warming material in the course text, Environmental Science, written by G. Tyler Miller, and reading several articles on the opposition of global warming, I find myself becoming not a hardcore skeptic, but someone that will no longer take information at face value without reviewing as many of the particulars as possible.…

    The author, “Contoski, asserts that global warming is scientifically unproven and that the facts reveal that the earth periodically experiences changing climates” (Global Warming Is a Myth). Contoski “denies that carbon dioxide emissions have any noticeable impact on global temperatures claims that human-made emissions are insignificant when compared to carbon output of natural sources that have always been beyond human control.” (Global Warming is a Myth)…

    When new information comes out about climate change it is easy to accept that information if it confirms something you had believed prior to (37). So when information that goes against your current position on climate change comes out it is hard to accept as being something positive. This attitude is what leads to comparisons being made to nearly every negative time in our history.…

    Global Warming is an issue demanding of world wide attention, yet widely ignored. Global Warming will change our planet drastically yet under the benefit of cheap energy we do nothing to shrink our carbon footprints. Many ignore the topic of Climate Change as they don’t believe in it, or simply don't understand why they should bother. This is exactly what Michael Pollan trys to argue in his article, “Why Bother?”, published by The New York Times,…

    Why challenge an observation that is backed up by heaps of quantitative observations since the mid 1900s and has imminent impact on our world today? Today, people in support of global cooling are either making a fool of themselves in order to garner attention or have been living under a rock for most of the 21st century. However, people concerned about global warming dismiss the claims concerning a present global cooling phenomenon too readily, almost like Broca's claim of the inferiority of women following his meticulous collection of data comparing the size of women's brains to men's brains. Stephen Gould's essay "Women's Brains" deconstructs the prevailing belief of women inferiority that was backed up by Broca's research in the 19th century in order to make the argument that nothing should be taken for granted during his time when evolutionary scientists were being challenged by dominant religious…

    “The Scientific Consensus on Climate Change” written by Naomi Oreskes is intended to let the readers understand that there is a consensus that anthropogenic global climate change is occurring. In her essay, Oreskes states that although some groups claim there is not substantial evidence that Earth’s climate is being affected by human activities, overall, the scientific community is in agreement that evidence is quite clear. “IPCC states unequivocally that the consensus of scientific opinion is that Earth’s climate is being affected by human activities,” (Oreskes 76) which further shows how scientists do, in fact, agree on climate change. The companies, on the other hand, do not agree that climate change is caused by humans because that would adversely affect their revenue and cost them more money to replace carbon dioxide emissions with something more environmentally friendly.…

    What exactly is global warming? Do you know the answer, maybe you do, however, taking a pretty good educated guess I would tend to think that most people think they have a pretty good idea when in actuality they have no clue what so ever about global warming. The current frenzy over global warming has galvanized the public and cost taxpayers billions of dollars in federal expenditures for climate research. It has spawned Hollywood blockbusters and inspired major political movements. It has given a higher calling to celebrities and built a lucrative industry for eager scientists. In short, ending climate change has become a national crusade. And yet, despite this dominant and sprawling campaign, the facts behind global warming remain as confounding as ever. Let’ s start by talking about the definition; according to Sir David King and Gabrielle Walker’ s, 2008, book titled “The Hot Topic “ global warming is defined as a gradual increase in the earth’s surface temperature. A more popular usage definition would be global warming is caused by human activity, or let’s look at a more technical term anthropogenic. The debate would be is global warming observed naturally or is it man made? Some might actually take on a debate about the natural causes, like is the sun getting hotter; or maybe the debate would lean more towards human causes, carbon dioxide , here is a good example: the exhaust from cars and power plants that pollute our air. Which side of the debate would you take? One in respect to thinking that global warming is a serious problem, then again maybe global warming has only clouded the issue or in simple terms; how the climate system really works and why man’s role in global warming is more myth than science, and how the global warming hype has corrupted Washington and the scientific community.…

    environmental policy by climate deniers has obstructed attempts to contain this crisis. Self-proclaimed climate science deniers or skeptics, as some prefer to be called, have several arguments even with the overwhelming consensus among scientists about the truth of climate change. A common argument that is espoused by many people is that greenhouse gas emissions are too small to substantially change our climate, and that the earth's climate has always warmed and cooled. They believe the recent rise in global temperature is the result of a natural climate oscillation, and will eventually give way to a cool period…

    A former United States Senator, Joe Lieberman, had this to say about global warming: “Today, we can see with our own eyes what global warming is doing. In that context it becomes truly irresponsible, if not immoral, for us not to do something.” The President of the French Republic asserted that “The time is past when humankind thought it could selfishly draw on exhaustible resources. We know now the world is not a commodity.” It is clear that global warming may be man’s greatest challenge - however, it seems as though many are still denying its existence.…

    Climate change is the largest threat to life on Earth that we currently face. Despite the overwhelming scientific consensus on the issue, only half of Americans believe that climate change is human-caused. Without a vast majority of the world’s population expressing concern about climate change and working to enact societal reform, little can be done to effectively address this extremely time-sensitive issue. In this paper, I will explore the main contributing factors to both literal and implicatory denial of climate change in the United States, and how to best combat it through political psychology, ecofeminism, and liberalism.…

    For the past decade now there has been a long ongoing controversy, this controversy being this issue of global climate change. It has been a subject many people have been aware of yet few have actually talked about with the general public, as a result is has become one of the most undermined, yet widely discussed issues being held today amongst primarily scientists. Although scientist heavily debate on the subject, making suggestions on what needs to be done and pointing out the causes for climate change; we as a group need to take action in finding out what is happening to the Earth. It is only educating the general public is the only way we can come closer to reversing the damaged caused by global warming and climate…

    Controversy over global warming exists as a dispute regarding the nature and consequences of global warming. The theory of global warning as presented in the mainstream media currently assumes that carbon dioxide is an atmospheric greenhouse gas and since humans are producing more carbon dioxide than previously, the temperature must therefore rise. The cause of global warming is not actually known, but in it 's simplest terms the debate boils down to whether or not global warming is caused by human interference or part of a naturally occurring cycle. The debate has recently become one-sided in favor of human interference due mostly to three factors: political pressure on scientists to produce research that supports the global warming theory, public misconception of what scientific consensus is, and an irresponsible that media promotes sensationalized viewpoints to sell advertising.…
