In his December article "The Heat is On: The warming of the world's climate sparks a blaze of denial", Ross Gelbspan said industry had engaged "a small band of skeptics" to confuse public opinion in a "persistent and well-funded campaign of denial".

Climate change denialor global warming denialis denialdismissal, or unwarranted doubt that contradicts the scientific consensus on climate changeincluding the extent to which it is caused by humansits effects on nature and human societyor the potential of adaptation to global warming by human actions.
The campaign to undermine public trust in essay on global warming wikipedia science has been described as a "denial machine" organized by industrial, political and ideological interests, and supported by conservative media and skeptical bloggers to manufacture uncertainty about global warming. The politics of global warming have been affected by climate change denial and the political global warming controversyundermining the efforts to act on climate change or adapting to the warming climate.
Organised campaigning to undermine public trust in climate science is associated with conservative economic policies and backed by industrial interests opposed to the regulation of CO 2 emissions.
Since the late s, oil companies have published research broadly in line with the standard views on global warming. Despite this, essay on global warming wikipedia, oil companies organized a climate change denial campaign to disseminate public disinformation for several decades, a strategy that has been compared to the organized denial of the hazards of tobacco smoking by the tobacco industryand often even carried out by the same individuals who previously spread the tobacco industry's denialist propaganda.
The terminology emerged in the essay on global warming wikipedia. Even though all scientists adhere to scientific skepticism as an inherent part of the process, by mid November the word "skeptic" was being used specifically for the minority who publicized views contrary to the scientific consensus.
This small group of scientists presented their views in public statements and the media, rather than to the scientific community. A November CBC Television documentary on the campaign was titled The Denial Machine. In addition to explicit denialsocial groups have shown implicit denial by accepting the scientific consensus, but failing to come to terms with its implications or take action to reduce the problem.
The terminology is debated: most of those actively rejecting the scientific consensus use the terms skeptic and climate change skepticismand only a few have expressed preference for being described as deniers, [32] essay on global warming wikipedia but the word "skepticism" is incorrectly used, as scientific skepticism is an intrinsic part of scientific methodology.
In academic literature and journalism, the terms "climate change denial" and "climate change deniers" have well-established usage as descriptive terms without any pejorative intent. Weart recognize that either option is problematic, but have decided to use "climate change denial" rather than "skepticism". Terms related to "denialism" have been criticized for introducing a moralistic tone, and potentially implying a link with Holocaust denial. In Decemberan open letter from the Committee for Skeptical Inquiry called on the media to stop using the term "skepticism" when referring to climate change denial.
They contrasted scientific skepticism—which is "foundational to the scientific method"—with denial—"the a priori essay on global warming wikipedia of ideas essay on global warming wikipedia objective consideration"—and the behavior of those involved in political attempts to undermine climate science.
They said "Not all individuals who call themselves climate change skeptics are deniers. But virtually all deniers have falsely branded themselves as skeptics.
By perpetrating this misnomer, essay on global warming wikipedia, journalists have granted undeserved credibility to those who reject science and scientific inquiry. The Committee for Skeptical Inquiry letter inspired a petition by climatetruth. org [54] in which signers were asked to 'Tell the Associated Press: Establish a rule in the AP StyleBook ruling out the use of "skeptic" to describe those who deny scientific facts.
Avoid use of skeptics or deniers. Research on the effect of CO 2 on the climate began inwhen Joseph Fourier inferred the existence of the atmospheric " greenhouse effect ". InJohn Tyndall quantified the effects of greenhouse gases on absorption of infrared radiation. Svante Arrhenius essay on global warming wikipedia showed that coal burning could cause global warming, and in Guy Stewart Callendar found it already happening to some extent.
In a scientist working essay on global warming wikipedia Shell suggested in a New Scientist article, that carbon cycles are too vast to upset Nature's balance, essay on global warming wikipedia. Nevertheless, the coal industry for decades thereafter publicly advocated the position that increased carbon dioxide in the atmosphere is beneficial for the planet. In response to increasing public awareness of the greenhouse effect in the s, conservative reaction built up, essay on global warming wikipedia, denying environmental concerns which could lead to government regulation.
With the Presidency of Ronald Reaganglobal warming became a political issue, with immediate plans to cut spending on environmental research, particularly climate-related, and stop funding for CO 2 monitoring.
Reagan appointed as Secretary of Energy James B. Edwardswho said that there was no real global warming problem. Congressman Al Gore had studied under Revelle and was aware of the developing science: he joined others in arranging congressional hearings from onwards, with testimony by scientists including Revelle, Stephen Schneider and Wallace Smith Broecker, essay on global warming wikipedia.
The hearings gained enough public attention to reduce the cuts in atmospheric research. In Sherwood B. Idso published his book Carbon Dioxide: Friend or Foe? which said increases in CO 2 would not warm the planet, but would fertilize crops and were "something to be encouraged and not suppressed", while complaining that his theories had been rejected by the "scientific establishment".
An Environmental Protection Agency EPA report in said global warming was "not a theoretical problem but a threat whose effects will be felt within a few years", with potentially "catastrophic" consequences.
Public attention turned to other issues, then the finding of a polar ozone hole brought a swift international response. To the public, this was related to climate change and the possibility of effective action, but news interest faded. Public attention was renewed amidst summer droughts and heat waves when James Hansen testified to a Congressional hearing on 23 Juneessay on global warming wikipedia, [69] stating with high confidence that long term warming was underway with severe warming likely within the next 50 years, and warning of likely storms and floods.
There was increasing media attention: the scientific community had reached a broad consensus that the climate was warming, human activity was very likely the primary cause, and there would be significant consequences if the warming trend was not curbed. From onwards industry-funded organizations including the Global Climate Coalition and the George C.
Marshall Institute sought to spread doubt among the public, in a strategy already developed by the tobacco industry. With the fall of communism and the environmental movement 's international reach essay on global warming wikipedia the Rio Earth Summitthe attention of U.
conservative think tankswhich had been organized in the s as an intellectual counter-movement to socialism, turned from the "red scare" to the "green scare" which they saw as a threat to their aims of private property, free trade market economies and global capitalism.
As a counter-movement, they used environmental skepticism to promote denial of the reality of problems such as loss of biodiversity and climate change. Inan EPA report linked second-hand smoke with lung cancer. The tobacco industry engaged the APCO Worldwide public relations company, which set out a strategy of astroturfing campaigns to cast doubt on the science by linking smoking anxieties with other issues, including global warming, in order to turn public opinion against calls for government intervention.
The campaign depicted public concerns as "unfounded fears" supposedly based only on "junk science" in contrast to their "sound science", and operated through essay on global warming wikipedia groupsprimarily the Advancement of Sound Science Center TASSC and its Junk Science website, run by Steven Milloy. A tobacco company memo commented "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 essay on global warming wikipedia establishing a controversy. Its website became central in distributing "almost every kind of climate-change denial that has found its way into the popular press. In the s, the Marshall Institute began campaigning against increased regulations on environmental issues such as acid rainozone depletionsecond-hand smoke, and the dangers of DDT.
These efforts succeeded in influencing public perception of climate science. The campaign essay on global warming wikipedia spread doubt continued into the s, including an advertising campaign funded by coal industry advocates intended to "reposition global warming as theory rather than fact," [84] [85] and a proposal written by the American Petroleum Institute intending to recruit scientists to convince politicians, the media and the public that climate science was too uncertain to warrant environmental regulation.
InGelbspan noted that his fellow journalists accepted that global warming was occurring, but said they were in "'stage-two' denial of the climate crisis ", unable to accept the feasibility of answers to the problem. These efforts by climate change denial groups were recognized as an organized campaign beginning in the s.
Gelbspan's Boiling Pointpublished indetailed the fossil-fuel industry's campaign to deny climate change and undermine public confidence in climate science. Referencing work of sociologists Robert Antonio and Robert Brulleessay on global warming wikipedia, Wayne A. White has written that climate change denial has become the top priority in a broader agenda against environmental regulation being pursued by neoliberals. The New York Times and others reported in that oil companies knew that burning oil and gas could cause climate change and global warming since the s but nonetheless funded deniers for years.
presidential candidate in questioned or denied the science of climate change. Ernesto Araújothe new Minister of Foreign Affairs appointed by the newly elected president Brazil 's president Jair Bolsonaro has called global warming a plot by " cultural Marxists " [] and has eliminated the Climate Change Division of the ministry.
The climate change denial industry is most powerful in the United States. government steps essay on global warming wikipedia address climate change as has the Republican leader in the U. A Pentagon report has pointed out how climate change denial threatens national security.
In the Center for Media and Democracy reported that the State Policy Network SPNan umbrella group of 64 U. think tanks, had been lobbying on behalf of major corporations and conservative donors to oppose climate change regulation. The Clexit Coalition claims to be: "A new international organisation which aims to prevent ratification of the costly and dangerous Paris global warming treaty". Some climate change denial groups say that because CO 2 is only a trace gas in the atmosphere essay on global warming wikipedia ppm, or 0.
Scientists have known for over a century that even this small proportion has a significant warming effect, and doubling the proportion leads to a large temperature increase, essay on global warming wikipedia. Geological Survey, and other reports, is that human activity is the leading cause of climate change. The burning of fossil fuels accounts for around 30 billion tons of CO 2 each year, which is times the amount produced by volcanoes.
Climate denial groups may also argue that global warming stopped recently, a global warming hiatusor that global temperatures are actually decreasing, leading to global cooling. These arguments are based on short term fluctuations, and ignore the long term pattern of warming. These groups often point to natural variability, such as sunspots and cosmic rays, to explain the warming trend. These factors are already taken into account when developing climate models, and the scientific consensus is that they cannot explain the observed warming trend.
At essay on global warming wikipedia May meeting of the United States House Committee on Science, Space, and TechnologyAlabama's Representative Mo Brooks claimed that sea level rise is caused not by melting glaciers but rather by coastal erosion and silt that flows from rivers into the ocean.
Climate change denial literature often features the suggestion that we should wait for better technologies before addressing climate change, when they will be more affordable and effective.
Global warming conspiracy theories have been posited which allege that the scientific consensus is illusory, or that climatologists are acting on their own financial interests by causing undue alarm about a changing essay on global warming wikipedia. Inresearch by Stephan Lewandowsky then of the University of Western Australia concluded that belief in other conspiracy theories, such as that the FBI was responsible for the assassination of Martin Luther King, Jr.
In February climate change denier Jim Inhofewho had previously called climate change "the greatest hoax ever perpetrated against the American people," claimed to have debunked the alleged hoax when he brought a snowball with him in the U. Senate chamber and tossed it across the floor. The role human activity plays is not known. Donald Trump tweeted in that the Chinese invented "the concept of global warming" because they believed it would somehow hurt U. In latehe called global warming a "hoax.
In Stefan Rahmstorf described how the media give the misleading impression that climate change was still disputed within the scientific community, attributing this impression to PR efforts of climate change skeptics. He identified different positions argued by climate skeptics, which he used as a taxonomy of climate change skepticism: [] Later the model was also applied on denial.
This taxonomy has been used in social science for analysis of publications, and to categorize climate change skepticism and climate change denial, essay on global warming wikipedia. The National Center for Science Education describes climate change denial as disputing differing points in the scientific consensus, a sequential range of arguments from denying the occurrence of climate change, accepting that but denying any significant human contribution, accepting these but denying scientific findings on how this would affect nature and human society, essay on global warming wikipedia, to accepting all these but denying that humans can mitigate or reduce the problems.
Powell provides a more extended list, [6] as does climatologist Michael E. Mann in "six stages of denial", a ladder model whereby deniers have over time conceded acceptance of points, while retreating to a position which still rejects the mainstream consensus: [].
Journalists essay on global warming wikipedia newspaper columnists including George Monbiot [] [] [] and Ellen Goodman[] among others, [] [] have described climate change denial as a form of denialism. Denialism in this context has been defined by Chris and Mark Hoofnagle as the use of rhetorical devices "to give the appearance of legitimate debate where there is none, an approach that has the ultimate goal of rejecting a proposition on which a scientific consensus exists.
Inenvironmentalist Bill McKibben accused President Obama widely regarded as strongly in favour of action on climate change [] of "Catastrophic Climate-Change Denial", for his approval of oil-drilling permits in offshore Alaska.
According to McKibben, the President has also "opened huge swaths of the Powder River basin to new coal mining. A study assessed the public perception and actions to climate change, on grounds of belief systems, and identified seven psychological barriers affecting the behavior that otherwise would facilitate mitigation, adaptation, and environmental stewardship.
The author found the following barriers: cognition, ideological world views, comparisons to key people, costs and momentum, discredence toward experts and authorities, perceived risks of change, essay on global warming wikipedia, and inadequate behavioral changes.
