The program will begin with a briefing on what peer-reviewed social science has revealed about the climate change disinformation campaign’s structure, funding, tactics, successes in blocking climate policies, and main participants. This will be followed by a discussion of:

  • Why despite fact that scientific skepticism is good and should be encouraged, this is not responsible skepticism?
  • Why this behavior cannot be excused as an exercise in free speech?
  • What damage has been caused by this campaign?
  • What kind of malfeasance is this? Tort, crime, fraud?
  • How to increase public international awareness of these developments?
  • What should be done about it?

Why Exxon’s and Other Fossil Fuel Companies’ Funding of the Climate Change Disinformation Campaign Cannot be Excused As an Exercise in Free Speech but Must be Understood as Morally Reprehensible Disinformation.

The tactics of the fossil fuel industry cannot simply be understood as its exercise of free speech. As we have seen in previous entries on the disinformation campaign on this website the disinformation Campaigns tactics have included:

1. Lying or reckless disregard for the truth about mainstream climate change science.
2. Cherry-picking mainstream climate science by focusing on an issue about which there may be some scientific uncertainty while ignoring a vast body of climate science which is well-settled.
3. Manufacturing non peer-reviewed climate change science claims.
4. The creating think tanks, front groups, and Astroturf groups which widely have disseminated untruthful claims about mainstream climate science and which were created to hide the real parties in interest, members of the fossil fuel industry.
5. Publishing and widely disseminating dubious manufactured climate change scientific claims that have not been subjected to peer-review.
6. Widely attacking mainstream climate scientist and journalists who have called for action on climate change.
7 Cyber-bullying mainstream climate scientists and journalists.

A few of these tactics are always ethically troublesome including creating conservative think tanks, front groups, Astroturf groups, and PR campaigns whose very creation was motivated to fool people about who the real parties in interest are behind claims that  attack mainstream climate science.  These organizations have also manufactured bogus climate science claims, cyber-bullied climate scientists and journalists, and widely published claims about climate change science that have not been subject to peer-review.

Corporations who fund these ethically troubling tactics are particularly ethically loathsome because they are using their economic power to deceive the public and intimidate mainstream scientists and journalists in the pursuit of economic self-interest.

Certain facts about climate change make these ethically obnoxious tactics even more reprehensible. They include the fact that climate change is a problem that the longer governments wait to take action to prevent damage, the worse the problem becomes and the more difficult and more expensive it becomes to solve it. The climate change disinformation campaign has been responsible for at least 30 years of inaction and, as a result, enormous and expensive greenhouse gas reductions are now required of the entire world to prevent potentially devastating and catastrophic climate change impacts. These impacts will likely be most harshly experienced by poor countries around the world which have done very little to cause theca climate problem. In addition, those most vulnerable to the harshest climate impacts have never consented to nor been consulted about waiting until all climate science uncertainties are resolved before action is taken.

For these reasons, just as screaming fire in a crowded theater when no fire exists is not construed to be a justifiable exercise of free speech, climate change science disinformation cannot be justified on free speech grounds and must be understood as the morally indefensible behavior of many fossil fuel companies, some corporations and industry organizations, and free market fundamentalist foundations that have funded the climate change disinformation campaign. Just as It is morally reprehensible to call fire in a crowed theater when there is no evidence of a fire because such reckless behavior will likely cause harm to people panicking to run to safety, telling those responsible for GHG emissions that there is no evidence that human activities are causing and threatening climate induced harms will likely cause great damage because inaction guarantees that atmospheric concentrations of GHG will continue to rise and remain in the atmosphere for thousands of years and likely cause great  harm and perhaps make it  impossible to prevent catastrophic damages to human health and ecological systems on which life depends. In fact not only is the the deceit propagated by the fossil fuel companies and others funding the disinformation campaign unjustifiable on free speech grounds it is so harmful that it may create legal liability for those entities who have funded the disinformation campaign.

Climate change disinformation is responsible for almost a 40 year delay in reducing GHG emissions to safe levels and harsh climate change impacts are already visible in many parts of the world caused by rising seas, much more intense storms, droughts, and floods. And so some of the great harm caused by the climate change denial countermovement is already being experienced even though the most catastrophic climate change harms will be experienced in future decades.

Insights from New Book on Sociology and Climate Change: Why Has an Understanding of the Sociological Causes of the Failure of Government to Respond to Climate Change and Identification of the Deep Ethical Problems with Most Arguments Against Climate Policies Been Missing from Most Climate Change Literature?

sociology and climate

This is the first in a series of three posts that will identify important insights about the social causes of climate change in a new book that examines climate change through the lens of sociology. This new book is Climate Change and Society, Sociological Perspectives by Riley Dunlap and Robert Bruelle, Oxford University Press, 2015, New York.

This book explains, among other things: (1) why sociological analyses of the causes of climate change as well as the identification of the serious ethical and moral problems with arguments of opponents of climate change policies have largely been missing from most climate change literature, (2) how certain corporations, industry organizations and free-market fundamentalist foundations have successfully prevented governments from adequately responding to climate change, and (3) how the failure to look at the causes of climate change through a sociological lens has partially blinded climate change policy advocates from a deeper understanding of the social causes of climate change and thereby prevented the development of potentially effective strategies to increase government responses to climate change

Before discussing the insights of this new important book, we note that many entries on this blog site have explained that for over 30 years opponents of climate change policies have mostly made two kinds of arguments in opposition to climate change policies.   First, they have argued that proposed policies designed to lessen the threat of human-induced climate change should be opposed because there has been inadequate scientific support for the conclusion that human activities are causing climate change harms which are threatening humans and ecological systems on which life depends. Second, opponents of climate change policies have made a variety of economic arguments that proposed climate change policies were too expensive, would destroy jobs, decrease national GDP, or otherwise would impose unacceptable costs on the nation’s economy.

In the United States and in a growing number of countries around the world these scientific uncertainty and unacceptable economic impact arguments have dominated disputes about proposed climate change policies since the mid-1980s. Proponents of climate change policies have almost always responded to these claims by disputing the factual claims about scientific uncertainty or unacceptable cost made by climate change policy opponents. And so, proponents of climate change policies have inadvertently allowed opponents of climate change policies to frame the public policy debate so as to limit the public controversy about climate change to disputes about scientific and economic “facts.” Largely missing from this three decade debate have been analyses of why the arguments of climate change policy opponents are not only factually flawed but ethically and morally bankrupt. Although a climate change ethics and justice literature has been growing for over a decade, the public debate about climate change  has largely ignored strong ethical and moral problems with the scientific and economic arguments that have been the consistent focus of the opponents of climate change policies.

Until the last few years, also largely missing from the public debate about climate change has been serious analyses of which organizations and interests have been most responsible for the arguments made by the opponents of climate change, who funded these organizations, what tactics have they used, and how can we understand that success of the climate change policy opposition in undermining serious responses to the growing threat of climate change.  In other words, missing from the public discussion about climate change has been serious analyses  of how the opponents of climate change policies have successfully blocked government responses to climate change despite increasingly louder and more intense calls from the  mainstream scientific community that government urgently must act to prevent catastrophic harms from climate change. That is, largely missing from the climate change debate has been any sophisticated analyses of how self-interested corporations. organizations, and ideological foundations have been able to manipulate a democracy to prevent the government from responding to a huge potential threat, matters which are the domain of the discipline of sociology.

Sociologists often seek to understand how self-interested minority groups within society can frequently hide the ethical and moral problems with their arguments by framing important public controversies in such a way that the ethical and moral problems raised by their arguments are hidden from public scrutiny. This framing works to hide the ethical and moral problems with arguments made by the opponents of government action to solve social and environmental problems by tricking the public to debate “factual” claims, such as those made by scientists or economists, as if there were no moral or ethical problems with these claims. As a result, in the case of climate change,  rather than debating whether it is morally acceptable for some people to put large numbers of other people at great risk from catastrophic harm on the basis that there’s some scientific uncertainty that the catastrophe will happen, the public is tricked into narrowly debating whether the catastrophe will happen with high levels of scientific certainty even in cases where waiting until all the uncertainties are resolved with high levels of confidence will likely make it too late to prevent the catastrophic harm. Rather than examining wether it is morally acceptable to delay action on climate change when delay will make the problem worse and the people most at risk have no say on whether to delay response action until scientific uncertainties are resolved, the public is tricked into debating the uncertainty. Rather than debating whether it is morally acceptable for one government to impose catastrophic harm on  hundreds of millions of other people, citizens are tricked into arguing about the magnitude of the economic costs that will be experienced by the country causing the harm if response action is taken.

As a result, in the United States, ethical and moral problems with the scientific uncertainty and unacceptable cost arguments made for over three decades by opponents of climate change policies have very rarely appeared in the US public debate about climate change that has been followed by the media. Although there has been a growing literature on the ethical and moral problems with arguments made by opponents of climate change policies and agreement among most ethicists that the arguments of most opponents of climate change are morally bankrupt, the mainstream climate change literature has rarely looked at the arguments of opponents of climate change policies through a moral lens.

And so, one of the reasons why ethical problems with the arguments most frequently made by opponents of climate change policies have neither rarely appeared in the dominant climate change literature nor become part of the public debate about what a country like United States should do in response to the threat of climate change is because economically powerful opponents of climate change policies have successfully narrowly framed the issues that have been discussed in the public debate, a common problem in democracies recognized by sociologists.

Also, largely missing in the public debate about climate change until very recently, has been sociological analyses of how those opposed to climate change have successfully created a social context about climate change, that is a cultural understanding of the problem in which individuals form opinions, Sociologists understand that culture is not fixed and and can change over time often in response to powerful forces that seek to affect widespread cultural understanding of a problem. Because individuals make decisions in light of the information about the problem provided by their culture, individual decisions about problems are often influenced by those who have sought to change the cultural understanding of the problem.

Although sociologists have begun in the last decade to explain how a climate change countermovement, a sociological term which will be discussed in the next entry in this series, has successfully influenced the cultural understanding of climate change in the United States, very little of the sociological explanation of how this countermovement has succeeded in  influencing the public’s understanding of climate change has appeared in the mainstream literature about climate change nor in media coverage of human-induced warming because the media also has largely reported on issues raised by opponents of climate change, namely, claims about scientific uncertainty and unacceptable costs of taking action.

The absence of sociological insights on how economic power has distorted the public’s understanding of climate change is most striking in the work of organizations such as the Intergovernmental Panel on Climate Change (IPCC) that study climate change primarily through a scientific lens although they  also have responsibility for making policy recommendations to decision-makers and in so doing have obligations to synthesize the relevant socioeconomic literature that should be considered by decision-makers.

In its first four assessments in 1990 (IPCC, AR1), 1995 (IPCC, AR2) , 2001(IPCC, AR4), and 2007 (IPCC, AR4), IPCC in its summary of relevant socioeconomic literature relevant to climate change relied almost exclusively on economic analyses of policy issues, rather than on the ethics and justice and justice literature.  In fact, in this regard, in the IPCC’s 5th Assessment  Report in 2014 (IPCC, AR5), in a new chapter on the Social, Economic, and Ethical Concepts, IPCC admitted expressly that in prior IPCC Reports “ethics has received less attention than economics, although aspects of both are covered in AR2.” (IPCC, AR5, Working Group III, Chapter 3, pg. 10)  Yet the treatment of ethics in IPCC Working Group III in AR2, was hardly a serious consideration of the implications of ethical and justice principles that should guide climate change policy given that the vast majority of text in this report was focused on traditional economic analyses which assumed that climate policy should maximize efficiency rather than assign responsibility for reducing the threat of climate change or pay for harm to those poor most vulnerable countries that have done little to cause climate change  on the basis of justice. In fact, the AR2 report includes many statements that would lead policy-makers to conclude that it is perfectly permissible to determine the amount of ghg emissions reductions any nation should be required to achieve solely on economic considerations. For instance, AR 2 says expressly that: “there is no inherent conflict between economics and most conceptions of equity.” (IPCC, 1995,  AR2, Working Goup III, pg. 87) Moreover. any fair reading of prior IPCC reports would conclude that policymakers were encouraged by IPCC to base policy on economic considerations such as those determined in cost-benefit analyses. Yet, as we have explained many times on this website. cost-benefit analysis used as a prescriptive tool for policy-making on climate change raise many serious ethical problems. (See, for example, Brown, 2008, Ethical Issues in the Use of Cost-Benefit Analysis of Climate Change Programs )

Why has economics and psychological literature dominated the work of IPCC whose mission includes synthesizing the relevant socioeconomic literature for policy-makers? The new Dunlap/Brulle book attributes the dominance of economics and psychology literature in the work of IPCC to the fact that the major focus of IPCC is science. Organizations like IPCC which are dominated by scientists after determining what needs to be done scientifically to reduce the environmental harm look to disciplines that offer advice on how to motivate individuals including economics and psychology to enact the responses to the problems that scientists have described need to be implemented (Brulle, R., & Dunlap, R., 2015, p. 8-9). And so the discipline of economics, which often assumes that individuals can be motivated to act by appealing to their economic self-interest, and psychology, which also focuses on how individuals can be motivated to change their individual behavior by appropriate messaging, have dominated the social science literature on climate change because scientific organizations like IPCC have turned to disciplines that offer potential strategies for motivating individual behavioral change after the scientific organizations explore precisely what needs to be done. These disciplines do not examine how powerful groups in society frame public policy issues in a way that hides ethical problems with status quo approaches to societal problems nor how economically dominant groups shape government’s and civil society’s potential responses to societal problems by changing the cultural understanding of the problem,  concerns which in the social sciences are the domain of sociology. Because the vast majority of climate change social science literature is focused on motivating individual behavioral change, ethical criticisms of economic rationality and analyses of how “value-neutral” discourses including economics have come to dominate approaches to solving climate change have played a very small role in the social science literature that IPCC has attempted to synthesize.. Explaining this phenomenon Brulle, R. & Dunlap, R. (2015), p. 8 conclude that:

An analysis of the social science literature finds that economics is the most widely represented social science discipline in climate research. Fundamental to economic analysis of climate change is the “rational actor” model embedded in the discipline. The object of the analysis is the individual and the decisions and principles that each individual brings to the marketplace. Given the widespread societal influence of economics, it comes as no surprise that it has been highly influential in climate change research.

For these reasons it is not surprising why IPCC has allowed economic considerations to dominate much of its analyses of to reduce climate change’s great threat in its first four assessments.

IPCC’s work initially defines what needs to be done scientifically to prevent climate change’s jharm and it should be expected that it would turn to the two disciplines that claim they understand how to motivate individuals to do what needs to be done, namely economics and psychology. Yet these disciplines have little to offer about how the cultural understanding of climate change has been deeply influenced by those with strong economic interests in maintaining the status quo nor invite citizens around the world to examine responses to climate change from the lens of ethics and morality.

Although, IPCC has made some improvement in covering ethics and justice in its 5th Assessment, much improvement is still needed (Brown, 2014).

The next entry in this series will examine the insights from the Dunlap/ Brulle book about how the climate change denial countermovement influenced the cultural understanding of climate change initially in the United States and later in other parts of the world.

Sociologist Brulle Explains How America has been Duped on Climate Change


As we have explained in numerous articles on this website that can be found under the category of “Disinformation campaign,”. the failure of the United States to respond to the enormous threat of climate change is most likely largely attributable to a morally reprehensible disinformation campaign which has been mostly funded by free-market fundamentalist foundations and fossil fuel companies.  In these articles we have explained that although scientific skepticism is important for science to advance, the climate change disinformation campaign’s tactics can’t qualify as responsible scientific skepticism because the tactics have included:

(a) lying about or acting with reckless disregard for the truth of climate change science,

(b) cherry-picking climate change science by highlighting a few climate science issues about which  there has been some uncertainty while ignoring enormous amounts of well-settled climate change science,

(c) using think tanks to manufacture claims about scientific uncertainty about climate science which have not been submitted to peer-review,

(d) hiring public relations firms to undermine the public’s confidence in mainstream climate change science,

(e) making specious claims about what constitutes “good” science,

(f) creating front groups and fake grass-roots organizations known as “astroturf” groups that hide the real parties in interest behind opposition to climate change policies, and

(g) cyber-bullying scientists and journalists who get national attention for claiming that climate change is creating a great threat to people and ecological systems on which life depends.

As we have explained in several articles on this website, these tactics are not responsible skepticism but morally reprehensible disinformation. See for instance, An Ethical Analysis of the Climate Change Disinformation Campaign: Is This A New Kind of Assault on Humanity?

In writing about the disinformation campaign, this website has often relied upon the work of Dr. Robert Brulle, a sociologist from Drexel University, and Dr. Riley Dunlap, a sociologist from the University of Oklahoma, along with a few other sociologists who have been examining the climate change disinformation campaign through the lens of sociology for over a decade.

Robert Brulle has just published the following OP-ED in the Washington Post:

America has been duped on climate change

Future generations will look back on our tepid response to global climate disruption and wonder why we did not act sooner and more aggressively. Climate change will adversely impact present and future generations, as well as all species on Earth. Our moral obligation to protect life requires us to act.

Yet even after the recently completed United Nations climate conference, we are still on track for dangerous levels of climate change. Why haven’t we acted sooner or more aggressively? One answer can be found in the split over the veracity of climate science.

Unfortunately, that path wasn’t taken. Instead, in 1989, a group of fossil fuel corporations, utilities and automobile manufacturers banded together to form the Global Climate Coalition. This group worked to ensure that the Kyoto Protocol, an international agreement to limit greenhouse gas emissions, was not adopted by the United States. In public statements, the Global Climate Coalition continued to deny that global warming was occurring and emphasized the uncertainty of climate science.

The spreading of misinformation continued. In 1998, API, Exxon, Chevron, Southern Co. and various conservative think tanks initiated a public relations campaign, the goal of which was to ensure that the “recognition of uncertainties (of climate science) becomes part of the ‘conventional wisdom.’”

While that coalition disbanded in 2001, ExxonMobil reportedly continued to quietly funnel climate misinformation through “skeptic” think tanks, such as the Heartland Institute, until 2006, when its funding was exposed. The company — the nation’s largest and wealthiest — continues to work with the American Legislative Exchange Council, a so-called public-private partnership of corporations and conservative legislators, to block climate change policies.

For years, ExxonMobil had been a participant in public efforts to sow doubt about climate change. Yet at at the same time, the corporation was at the leading edge of climate science and its executives were well informed regarding the scientific consensus on climate change. This allegedly deceitful conduct has generated public outrage and recently led New York’s attorney general to initiate an investigation into whether ExxonMobil has misled the public and investors about the risks of climate change.

While important, these legal proceedings cannot fully address the larger moral issues of corporate social and political responsibility. Just as Congress investigated the efforts of the tobacco industry to dupe the public into believing its products were harmless, we need a full and open inquiry into the conduct of ExxonMobil and the other institutions whose misinformation campaigns about science have delayed our efforts to address climate change.

The central concern here is the moral integrity of the public sphere. The Declaration of Independence says the legitimacy of government is based on the consent of the governed. But when vested interests with outsize economic and cultural power distort the public debate by introducing falsehoods, the integrity of our deliberations is compromised.

Such seems the case today when we consider the fossil fuel industry’s role in distorting discourse on the urgent topic of climate change. If vested economic interests and public relations firms can systematically alter the national debate in favor of their own interests and against those of society as a whole, then the notion of democracy and civic morality is undermined. Congress can and should act to investigate this issue fully. Only then can we restore trust and legitimacy to American governance and fulfill our moral duty to aggressively address climate change.

Dr. Robert Brulle, Washington Post, January 8th

Dr. Brulle and Dr. Dunalp have just edited a new book, which synthesizes some of main sociological analysis on the climate change policy debate which is well worth reading by anyone interested in climate change. The book is Climate Change and Society, Oxford University Press.

This website has been interested in working out the moral and ethical implications of the conclusions made by the sociologists working on climate change.

Issues the Media has Poorly Dealt With About the Paris Climate Deal: The Enormity and Urgency of the Climate Threat that has been Exacerbated by Political Opposition to Climate Policies

I. Introduction

This article explains the first two of several issues that citizens need to understand to evaluate appropriate national responses to climate change after the Paris Agreement. Although the mainstream media in the United States and other developed countries has widely reported on some aspects of the Paris Agreement, this series will describe important issues that are largely being ignored by press coverage of the Paris deal.

The first issue is why a 25-year delay in responding to increasingly stronger scientific warnings of the danger of human-induced climate change has made the problem much more threatening. The second is the urgency of the need for hard-to-imagine action to dramatically reduce greenhouse gas (ghg) emissions at all scales, that is globally, nationally, and locally, but particularly in high-emitting nations such as the United States in light of the limited amount of ghgs that can be emitted by the entire world before raising atmospheric ghg concentrations to very dangerous levels and in light of the need to fairly allocate ghg emissions reductions obligations around the world.

Media in the US has accurately reported on some positive aspects of the Paris deal including:

a. 186 nations have made commitments to reduce the threat of climate change although nations conceded in Paris that current commitments need to be upgraded to prevent dangerous climate change.

b. All nations agreed to limit the increase in global average temperatures to “well below 2 °C above pre-industrial levels” – the level beyond which scientists believe the Earth will likely begin to experience rapid global warming and to  “pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels”, a warming amount which may also cause serious global harms particularly to many poor, vulnerable nations. Also the Paris Agreement says by the second half of this century, there must be a balance between the emissions from human activity such as energy production and farming, and the amount that can be captured by carbon-absorbing “sinks” such as forests or carbon storage technology.

c. All countries agreed to submit updated plans that would ratchet up the stringency of emissions by 2020 and every five years thereafter.

d. Nations agreed to report to each other and the public on how well they are doing to implement their targets and to track progress towards the long-term goal through a robust transparency and accountability system.

e. Developed countries agreed to provide funding to help developing countries make the costly shift to green energy and shore up their defenses against climate change impacts like drought and storms and rich nations must report every two years on their finance levels — current and intended. The document refers  $100 billion a year that rich countries had previously pledged to muster by 2020 as a “floor”. Under the new agreement the amount must be updated by 2025.

The Paris Agreement has been widely and accurately portrayed in the mainstream media as creating a policy framework that has the potential to reduce the threat of climate change if nations greatly step up to what they have committed to do.  (This framework could have been tightened by including more specific language on several issues proposed by some countries but rejected by others on such matters as human rights, losses and damages, legal effect of the agreement, and financing of adaptation among others, yet the framework includes provisions that these issues can be considered in the years ahead.) However, the enormity of the challenge facing humanity from climate change and the special responsibilities of high-emitting developed nations in particular has not been covered in the mainstream press at least in the United States.

II. The Urgency and Enormity of the Need to Reduce GHG Emissions

Although the mainstream media has widely reported on the fact that the national ghg emissions reductions that were made before the Paris COP are not sufficient to limit warming to  2 degrees C, the media, at least in the United States, has been largely failing to report on the urgency and enormity of the need to rapidly reduce ghg emission globally and how further delays in taking action will dramatically make the problem much more threatening.

Looking at the delay caused by the climate change policy opposition in the United States is illustrative of the harm caused by political opposition to climate change policies worldwide.

damage done by republicans

The above illustration depicts, in a very abbreviated and sketchy form, that as the scientific evidence of the threat from human-induced climate change became stronger over a 40-year period and as the US political opposition to climate change policies successfully fought to prevent the adoption of robust US climate policies, the atmospheric concentration of CO2 rose from below 320 ppm (parts per million) to current levels of over 400 ppm.  (For a much more rigorous analysis of the role of the climate change policy opposition in US climate policy formation see Brown 2002, chap 2 and Brown 2012, chap 2 and numerous articles on this website under the category of “disinformation campaign.”)

The rise in atmospheric CO2 levels is, of course, not only attributable to the US ghg emissions, yet the United States has played a major blocking role in preventing international action on climate change up until the recent more constructive role of the Obama administration which recently made commitments before the December Paris meeting to reduce US CO2 emissions by 26% to 28 % by 2025 below 2005 levels. However these new US commitments have not yet been implemented in the United States, and even if fully implemented still don’t represent the US fair share of safe global emissions (see report on US INDC. The US commitment, because it is based on a 2005 baseline, masks the fact that is only  a mere 13-15 per cent below 1990 levels by 2025, the baseline used by most of the world. For a discussion of the problems with the Obama administration commitment see report Captain America)

Furthermore, the Obama administration’s commitments still face strong opposition from the US climate change political opposition and are very likely to be rejected if a Republican becomes the next US President in 2016. Furthermore as long as US ghg emissions are exceeding the US fair share of safe global emissions, US ghg emissions are making the already very perilous climate change threat worse.

A detailed description of the climate change disinformation campaign that is responsible for much of the political opposition that has been largely responsible for the over 25-year US delay in responding to the scientific warnings about the threat of climate change is beyond the scope of this article but has been extensively discussed on this website under the category of “disinformation campaign.”

To fully understand the nature of the harm caused by this delay it is necessary to understand the policy implications of a “carbon budget” that must limit global emissions to avoid dangerous warming levels. . Bathtub revised 1pptx

To understand the policy implications of a carbon budget it is helpful to see the atmosphere as like a bathtub to the extent that it has limited volume and has been filling up with ghg so that atmospheric concentrations of CO2 have been rising in proportion to human activities which release ghgs.

CO2 levels remained relatively stable for 10,000 years before the beginning of the industrial revolution at approximately 280 ppm (the lower line in the bathtub). Human activities have been responsible from elevating CO2 atmospheric concentration levels to the current concentration of approximately 400 ppm (the second line from the bottom of the tub). Although there is considerable scientific evidence that limiting warming to 1.5 degrees C is necessary to prevent very dangerous warming, a fact implicit in the recent Paris Agreement in which nations agreed to work to keep warming as close as possible from exceeding 1.5 degrees C additional warming, if the international community seeks to limit warming to 2 degrees C it must assure that global emissions do not exceed the number of tons of CO2 emissions that will raise atmospheric concentrations to levels that will cause warming of 2 degrees C. This number, that is the number of tons of CO2 emissions that can be emitted before atmospheric concentrations exceed levels that will cause dangerous climate change, is what is meant by a carbon budget.

cabon budget hour glass


This illustration, using figures from the most recent 2014 IPCC report, depicts that because only 800 gigatons of CO2 can be emitted by humanity before creating a 66% probability that a 2 degree C warming limit will be exceeded and humans have by 2011 already emitted  530 gigatons of CO2, there are only 270 gigatons of CO2 that may be emitted after 2011 to limit warming to 2 degrees C. (For a more detailed explanation of these figures see, Pidcock 2013)

The enormity of the challenge for the international community to keep warming from exceeding dangerous level can be understood by the fact that the remaining carbon budget is so small, that is approximately 270 gigatons of CO2, and current global ghg emissions are in excess of 10 gigatons per year and still rising, which means that even if the international community could stabilize global CO2 emissions levels there would be nothing left to allocate among all nations in 23 years. This grim fact is even bleaker if the international community concludes that it should limit warming to 1.5 degrees C, a conclusion that might become more obvious if current levels of warming start to make positive feedbacks visible in the next few years such as methane leakage from  frozen tundra or more rapid loss of arctic ice.

The concept of the carbon budget explains why waiting to reduce ghg emissions levels to a certain percentage in the future is more harmful than rapid reductions earlier because the longer it takes to reduce emissions the more the remaining budget is consumed. For this reason, a joint research project between Widener University Commonwealth Law School and the University of Auckland recommended in Paris that national climate commitments be stated in tons of emissions over a specific period rather than percent reductions by a given date because waiting to the end of specific period to achieve percent reductions will cause the total tons of ghg emitted to be higher than if reductions are made earlier.

The enormous significance of the carbon budget can be seen  from the following chart prepared by the Global Commons Institute.

INDC implications aubrey

The illustration depicts the enormity and urgency of global emissions reductions that would be necessary to limit warming to 1.5 or 2.0 degrees C given the steepness of the reductions curves necessary to limit warming to 2.0 degrees C with a  50% probability (the red dotted line), 2.0 degrees C with a 66% probability (the blue dotted line), and 1.5 degrees C (the green dotted line). The steepness of these curves superimposed on actual national ghg emissions levels is an indication of the enormity of the challenge for the international community because the emissions reduction curves are much steeper than reductions that can be expected under projections of what current national commitments are likely to achieve if fully implemented. The steepness of these reductions curves is somewhat controversial because any calculation of a carbon budget which determines the steepness of the the needed reduction curve must make assumptions about when positive feedbacks in the climate system will be triggered by rising temperatures, yet these controversies are reflected in giving different probabilities about the likelihood of achieving a specific warming limit.  Yet even carbon budgets which have been discussed in the carbon budget literature which have assumed lower amounts of positive feedback yield very. very steep reduction curves.

The enormous increase in the magnitude of the challenge that has been caused by delay given the limited carbon budget can be seen from a recent statement of Jim Hansen who said that “the required rate of emissions reduction would have been about 3.5% per year if reductions had started in 2005 and continued annually thereafter, while the required rate of reduction, if commenced in 2020, will be approximately 15% per year. Without doubt every delay in reducing ghg emissions makes the problem more difficult and more expensive to solve. For this reason, all nations should aim to reduce ghg emissions as quickly as possible and any nation which opposes doing so on the basis of scientific uncertainty should be asked if the nation is willing to take full legal and financial responsibility for harms caused by any delay.

III. On the Additional Need to Make National GHG Emissions Allocations on the Basis of  Equity

The above chart also helps explain the gross unfairness of requiring all nations to reduce by the same percentage reduction rates to achieve the globally needed emissions reductions because some nations are emitting at vastly higher per capita rates and some nations are responsible much more than others for raising atmospheric ghg concentrations to current dangerous elevated levels which are now in excess of 400 ppm CO2. .If each nation had to reduce their ghg emissions only to conform to the rates described in the reduction curves in the above chart despite their steepness, it would lead to grossly unfair results because of great differences among countries in per capita and historical emissions levels and urgent needs to increase energy consumption to escape grinding poverty in poor developing countries.

Per capita carbon levels by nations

Percapita nationa

The above chart gives some indication of huge differences in nations in per capita ghg emissions. If nations must reduce their ghg emissions by the same percentage amount, then such an allocation will freeze into place huge differences in per capita rights to emit ghg emissions into the atmosphere. If, for instance, the United States and India are required to reduce ghg emissions by the same percentage amount, for instance 90%, then the US per capita emissions of approximately 20 tons CO2 per capita would allow US citizens to emit CO2 at the rate of 2 tons per capita while the current India per capita emissions of approximately 1.8 tons per capita would mean that the Indian citizens could emit only at the rate 0.18 tons per capita even though India needs to dramatically increase its energy use to assure that hundreds of millions of people economically rise out of  grinding poverty and India has comparatively done little to cause the existing problem. This result is clearly grossly unfair particularly in light of the fact that India has emitted far less tons of CO2 than most developed countries and therefore is less responsible for causing the existing problem than many developed nations. If some consideration for historical responsibility is not taken into account in allocating national responsibility for ghg emissions reductions, then those poor nations which have done very little to create the current threat of climate change will be required to shoulder a greater burden of needed global ghg emissions obligations than would be required of them if responsibility for the existing problem is not taken into account. As a result, although there are reasonable differences of opinion among nations about how to consider historical national ghg emission in determining national ghg emissions reductions allocations, including when, for instance, historical responsibility should be measured, almost all equity frameworks agree that prior levels of ghg emissions must have some consideration in national ghg allocations.There is also reasonable disagreement in the equity literature about what weight should be given to other matters that are widely considered to be valid considerations in determining fairness including the economic capability of rich countries to pay for ghg emissions reductions technologies and per capita considerations.

Yet unless fairness is taken into account in allocating national ghg targets necessary to prevent dangerous climate change, those nations who are mostly responsible for current elevated atmospheric ghg concentrations will not be held responsible for their past ghg  emissions while nations who have done almost nothing to cause the rise of atmospheric concentrations will be held equally responsible for lowering emissions.

From the above illustration it can be seen that the United States and the EU are more responsible for raising atmospheric concentrations to current dangerous levels than than the rest of the world combined.

Many opponents of climate change policies argue that countries like the United States should not have to reduce their ghg emissions until China reduces its emissions by comparable amounts because China is now the largest emitter of all nations in terms of total tons, yet such an argument usually ignores the historical responsibility of countries like the United States which the following illustration reveals is more than twice as responsible for current elevated atmospheric ghg concentrations than China is. (For a discussion of the fact that there are both a strong ethical and legal arguments that explain why  no nation may use the claim that it need not reduce its ghg emissions until other nations do so, see, Brown 2012 p 214 )

hansen ghg emissions by country

Source, Hansen, Evaluating Dangerous Climate Change

Although there is a difference of opinion in the “equity” literature about how to consider valid equity considerations including per capita, historical emissions levels, and the economic capabilities of nations to fiance non-fossil energies, all nations agree that national commitments about ghg emissions reductions must consider fairness.

For this reason the Paris Agreement calls for nations to reduce their ghg emissions “to reflect equity and the principle of common but differentiated responsibilities and respective capabilities, in the light of different national circumstances.” (Paris Agreement, Article 2)

In other words, the international community has agreed that national ghg emissions reductions commitments must be based on “equity” or “fairness.”

And so as a matter of international law under the Paris Agreement, national commitments to reduce ghg emissions must be based on achieving a warming limit as close as possible to 1.5 degrees C but no greater than 2 degrees C, a requirement often referred to as the level of “ambition” but national commitments also must be based on “equity” or “fairness.” Although there are some reasonable disagreements among many engaged in climate policy debates about what “equity” or “fairness” requires, all nations have agreed that their obligations to reduce ghg emissions must consider equity or fairness principles.

However, if high-emitting nations take the “equity” and “fairness” requirement seriously, they will need to not only reduce ghg emissions at very, very rapid rates, a conclusion that follows from the steepness of the remaining budget curves alone, but also they will have to reduce their ghg emissions much faster than poor developing nations and faster than the global reductions curves entailed only by the need to stay within a carbon budget.

The above illustration prepared by the Global Commons Institute shows that even if only one equity consideration is taken into account, in this case per capita fairness, the USA ghg emissions reductions must be much faster than the rest of the world. Other organizations who have made calculations of the US fair share of the remaining carbon budget using different equity factors have concluded that the US fair share of safe global emissions is even smaller than that depicted in the above chart.  For instance the following illustration prepared by EcoEquity and the Stockholm Environment Institute shows that the US fair share of global emissions, making what the authors of the report claim are moderate assumptions of what equity requires, demonstrates that equity not only requires the US to reduce its emissions to zero quickly almost immediately but that US obligations to prevent a 2 degree C rise requires the US to substantially fund ghg emissions reductions in other countries by 2025 despite achieving zero emissions by 2020.

equity band

Source Athanasiou, et al, National Fair Shares

The above illustration, following the assumptions about what equity requires made by the authors of the report about how to determine US emissions reductions obligations, leads to the conclusion not only does the United States need to achieve zero carbon emissions by 2020, the US must reduce  its emissions by -141% from 1990 levels by 2025. National Fair Shares. p 18. This is to be achieved, according to the report, by US financial support for reductions in developing countries  .

Although national ghg emissions reductions commitments that have been evaluated by different organizations which have made different assumptions about how to calculate what equity requires of nations have come to different conclusions, most evaluations of national commitments made through an equity prism done before Paris concluded that even if they high emitting nations achieve net zero emissions by 2050, they will need, as a matter of equity and justice, to help pay the costs of emissions reductions in poor developing countries or finance technologies that will remove carbon from the atmosphere. The reasons for this are that the remaining carbon budget is so small, the per capita and historical emissions of high-emitting developed nations are so large compared to poor developing countries, and the  financial resources of developed countries are so large compared to poor developing countries that equity considerations demand that the high-emitting nations financially help developing nations achieve their targets.

IV. Conclusion

Without doubt, if nations reduce their ghg emissions to levels required of them by ambition, that is levels required by conformance with a carbon budget necessary to assure that future warming is limited to 2 degrees C or 1.5 degrees C adjusted to also consider equity and fairness, the international community is faced with an extraordinarily daunting challenge. Moreover, any delay in meeting this challenge will make the problem worse.

The Paris Agreement created a framework for solving the climate problem, yet the post-Paris media has poorly covered the implications for nations of what sufficient  ambition and fairness should be required of nations when they formulate national climate policies if very dangerous climate change is to be avoided.  As a result, there appears to be little awareness of the huge damage that will likely be caused by further delay. The research report of Widener University Commonwealth Law School and the University of Auckland has revealed that there appears to be little awareness around the world about what ambition and equity requires of nations when they formulate national climate change policies. As a result the international community is not likely to respond with sufficient urgency and ambition unless greater awareness of the policy implications of the need to live within a carbon budget at levels required of nations because of equity and fairness considerations.

Because of  this, perhaps the most important immediate goal of climate change policy proponents is to help educate civil society and governments about the need to move urgently to make extremely rapid decreases in ghg emissions whereever governments can and to the maximum extent possible in light of the policy implications of limiting national ghg emissions to levels constrained by a carbon budget and in  response to what fairness requires of nations. .

The Seeds of the Corporate Funded Climate Disinformation Campaign, the 1971 Lewis Powell Memo


Although numerous articles on this website have acknowledged that responsible scientific skepticism is a positive force in the advancement of science, as we have explained in numerous articles under the category of  “disinformation campaign” there has been a well-funded climate change disinformation campaign that since the 1980s has been engaged in the following ethically dubious tactics including:

  • Lying or reckless disregard for the truth about climate science,
  • Cherry picking the science by focusing on unkowns while ignoring what is well-settled in climate science,
  • Cyber-bullying and ad hominem attacks on scientists and journalists,
  • Manufacturing bogus, non-peer-reviewed climate science through the creation of  ideologically motivated conferences and publications,
  • The use of ideological think tanks to promote the views of climate change deniers through their media outreach, speakers bureaus, publications, and conferences,
  • The use of front-groups and fake grass-roots organizations, known as Astroturf groups, to promote the views of climate change deniers that hide the real parties in interests,
  • Making specious claims about “bad science” that are based upon the dubious assumption that no conclusions in science can be made until everything is proven with high levels of certainty.

This website contains numerous articles on the many ethical problems with the corporate and free-market fundamentalist foundation funded climate change disinformation campaign that was in full bloom by the  mid-1980s. These articles examine the tactics of the disinformation campaign through an ethical lens that distinguishes it from responsible scientific skepticism.  See, for instance:

Irresponsible Skepticism: Lessons Learned From the Climate Disinformation Campaign

The climate change disinformation campaign that arose in the 1980s was part of what sociologists call a countermovement, that is a movement that arises when elements of society are threatened by social movements that are perceived to potentially adversely affect their interests.

An environmental countermovement arose in the United States in response to the rise of the modern environmental movement which was born in the late 1960s in response to among other things, the publications in 1962 of Rachel Carson’s Silent Spring and a growing number of highly visible pollution events including the Santa Barbara oil spill and the fire in the Cuyahoga River in 1969.  After Silent Spring, many more citizens understood that toxic substances were widely distributed throughout the world at levels that could harm human and animal health.

The beginning of the modern environmental movement in the United States has often been pegged by environmental historians to Earth Day on April 22, 1970. On the first Earth Day in New York City tens of thousands of people concerned about environmental issues marched and paraded in lower Manhattan and many thousands attended speeches in Union Square Park. New York City was only one of hundreds of locations throughout the United States where Earth Day events took place on April 22, 1970.

The rapid rise of the modern environmental movement that was undeniable by April 1970 was perceived to be a threat to many members of the US business community, As a result, soon after the first Earth Day in 1970, the environmental countermovement began to organize. Sociologist Robert Brulle summarizes the rise of countermovements as follows:

Counter-movements originate as the change movement starts to show signs of success by influencing public policy, and threatening established interests. The elites of these interests then respond to these threats by fostering countermovements to protect their interests by opposing or challenging social movements. ….The countermovement organizations that emerge take the form of elite driven efforts to mobilize economically impacted populations, or populations that share similar interests of ideologies. [Brulle]

Many sociologists and environmental historians also attribute the speed of the rise of the environmental countermovement to a 1971 memo of Lewis Powell to the US Chamber of Commerce that was based on the claim that the American free enterprise system was under attack from the social movements that arose in the 1960s including the environmental movement.

Powell was a corporate lawyer, a former president of the American Bar Association, and a board member of eleven corporations, including Philip Morris and the Ethyl Corporation, a company that made the lead for leaded gasoline. Powell had also represented the Tobacco Institute, the research arm of the tobacco industry, and various tobacco companies. Within two months after his 1971 memo, President Richard Nixon nominated Powell to sit on the U.S. Supreme Court, where he served for fifteen years.

The Powell memo criticizes corporations for their lack of vigor in responding to the challenges to free enterprise that were growing in the beginning of the 1970s and calls for a much more aggressive response from the business community that it claims is needed to protect fee enterprise from criticism from college campuses, the pulpit, the media, the intellectual and literary journals, the arts and sciences, and from politicians. (Powell Memo)

The memo specifically recommended that businesses:

  •  Designate a member of senior management who has responsibility to fight attacks on the free enterprise system,
  • Expand the role of business organizations to fight the threats of the free market including the US Chamber of Commerce which has the time, finances, and organizational capacity to powerfully unify the response of the business community,
  • To counter criticism of the business community from college campuses, business organizations such as the Chamber of Commerce should support scholars who will defend the free enterprise system, develop speakers and support speakers’ bureaus that will counter the liberal rhetoric coming from college campuses, subject textbooks to ideological review, insist on equal time for speakers exposing the views of the business community for speakers on campuses, insist that college faculties be balanced by those who will defend the free enterprise system, request that graduate schools of business include courses that support the free enterprise system, encourage local chambers of commerce to provide the views of the business community in high schools, establish staff who work with the media to communicate to the general public the views of the business community, monitor and criticize television programs that unfairly criticize the free enterprise system and where appropriate file complaints with the Federal Communications Commission, monitor radio and other media and pressure them to cover the views of defenders of the free enterprise system, support scholars who support the free enterprise system to publish in scholarly journals, establish incentives for scholars to publish defenses of free enterprise in books, papers, and pamphlets, spend more money on advertising that expressly supports the free market system.
  • Much more aggressively support politicians who support the interests of the business community.
  • Become much more involved in the judicial system to support the interests of the business community by, among other things, filing litigation and amicus curiae briefs in important cases.
  • Harness the power of corporate shareholders to advance the interests of the business community.
  • Dramatically increase finances in support of opposition to those threatening  unfettered markets including increasing the staff of organizations like the Chamber of Commerce to engage in this work.
  • Much more aggressively defend the free enterprise system by among other tactics linking personal freedom to free enterprise.

Shortly after the Powell memo was sent to the Chamber of Commerce in 1971, much more aggressive tactics in defending the free enterprise system by the business community became evident including the following:

  • The organizational counterattack of business in the 1970s was swift and sweeping — a domestic version of Shock and Awe. The number of corporations with public affairs offices in Washington grew from 100 in 1968 to over 500 in 1978. In 1971, only 175 firms had registered lobbyists in Washington, but by 1982, nearly 2,500 did. The number of corporate PACs increased from under 300 in 1976 to over 1,200 by the middle of 1980.(Bill Moyers, The Powell Memo: A Call-to-Arms for Corporations, September 14, 2012)
  • In 1972, three business organizations merged to form the Business Roundtable, the first business association whose membership was restricted to top corporate CEOs.The Business Roundtable quickly developed into a formidable group, designed to mobilize high-level CEOs as a collective force to lobby for the advancement of shared interests. Within five years the new mega-organization had enlisted 113 of the top Fortune 200 companies, accounting for nearly half of the economy. (Bill Moyers, The Powell Memo: A Call-to-Arms for Corporations, September 14, 2012) .
  • Business also massively increased its political giving — at precisely the time when the cost of campaigns began to skyrocket (in part because of the ascendance of television). The insatiable need for cash gave politicians good reason to be attentive to those with deep pockets. Business had by far the deepest pockets, and was happy to make contributions to members of both parties.(Bill Moyers, The Powell Memo: A Call-to-Arms for Corporations, September 14, 2012)
  • From the late 1970s to the late 1980s, corporate PACs increased their expenditures in congressional races nearly fivefold. (Bill Moyers The Powell Memo: A Call-to-Arms for Corporations, September 14, 2012)
  • Powell’s legal recommendations inspired “a multi-faceted, comprehensive, and integrated campaign” coordinated and funded by large corporations and rightwing foundations “to create taxpayer subsidized law firms… to rewrite American jurisprudence… advanc[e] their agenda before judges, lawyers, legal scholars, and government policy makers… [and] sought to assure control over the future direction of the law” by installing ideologically friendly faculty in law schools, as well as organizing and rewarding students with scholarships and clerkships under conservative judges, and placing those judges on the bench. (Jerry M. Landay, The Attack Memo that Changed the World)
  • The California Chamber of Commerce picked up on the Powell Memo and proposed what became in 1973 the Pacific Legal Foundation, the first of eight regional litigation centers. The Olin, Scaife, Bradley, Smith Richardson, and Coors’ Castle Rock foundations, and others, continue to underwrite these operations. , (Jerry M. Landay, The Attack Memo that Changed the World)
  • Huge corporations, including Powell’s Philip Morris, invested millions of dollars in the Chamber of Commerce’s National Chamber Litigation Center and other legal foundations to bring litigation demanding new corporate rights. In rapid succession, corporations and supporters funded the Pacific Legal Foundation, the Mid-Atlantic Legal Foundation, the Mid-America Legal Foundation, the Great Plains Legal Foundation (Landmark Legal Foundation), the Washington Legal Foundation, the Northeastern Legal Foundation, the New England Legal Foundation, the Southeastern Legal Foundation, the Capital Legal Center, the National Legal Center for the Public Interest, and many others.(Clements)
  • The number of companies with Washington lobbying offices grew from 175 in 1971 to 2,445 a decade later. Along with 2,000 different trade associations, businesses have a combined Washington staff of 50,000, plus 9,000 lobbyists and 8,000 public relations specialists.  (Smith. Who Stole the American Dream)
  • Since 1972 and continuing to the present, conservative foundations also heavily underwrite scores of institutes and policy centers that operate along the general lines proposed in the Powell memo. These agitprop operations are modeled on the Heritage Foundation, and include the Manhattan Institute, the Cato Institute, and Citizens for a Sound Economy, the National Association of Scholars and Accuracy in Academe, Brent Bozell’s Media Research Center, and Reed Irvine’s Accuracy in Media. (Jerry M. Landay, The Attack Memo that Changed the World)
  • Business expanded its acquisition of media to help it control the message and viewpoint. Today six corporations control 97% of all media in the US. By insisting on the mandate of “balance” any unwanted fact or statement can be countered and diminished by claiming a need for equal time. These will generally be provided by the dozens of conservative think tanks and speakers. Television, radio and magazines are closely scrutinized for where and when to counter or insert business friendly news, information or preference. Most media today expends vast amounts of coverage on business and financial news. (Ron Sandahl)
  • Powell’s court opinion in First National Bank of Boston v. Bellotti shifted the direction of First Amendment law by declaring that corporate financial influence of elections should be protected as individual political speech. This directly set up Citizens United to become law. (Ron Sandahl).
  •  Huge corporations, including Powell’s Philip Morris, invested millions of dollars in the Chamber of Commerce’s National Chamber Litigation Center and other legal foundations to bring litigation demanding new corporate rights. By 1978, the millions of dollars invested in the radical corporate rights campaign began to pay off. The first major victory for the corporate rights advocates came in 1978, with a corporate attack on a Massachusetts law in First National Bank of Boston v. Bellotti. Several international corporations — including Gillette, the Bank of Boston, and Digital Equipment Corporation — filed a lawsuit after the people of Massachusetts banned corporate political spending intended to influence a citizen referendum. Justice Lewis Powell cast the deciding vote and wrote the 5–4 decision wiping off the books the people’s law intended to keep corporate money out of citizen ballot questions. For the first time in American history, corporations had successfully claimed “speech” rights to attack laws regulating corporate money in our elections. (Clements)
  • With that success, an emboldened corporate rights campaign next attacked energy and environmental laws. In the 1982 case of Central Hudson Gas & Electric Corporation v.Public Service Corporation of New York, utility corporations and the array of corporate legal foundations all argued that a New York law prohibiting utility corporations from promoting energy consumption violated the corporations’ rights of free speech. The corporations won again, and again Justice Powell wrote the decision for the activist Supreme Court that he had imagined in his 1971 Chamber of Commerce memo. Over a period of six years, Justice Powell wrote four key corporate rights( decisions for the Supreme Court. (Clements)
  • Although many new voices have emerged in the 40 years since it circulated Powell’s memo, the U.S. Chamber has expanded its leadership position within the corporate power movement, leading dozens of judicial, legislative and regulatory fights each year. Measured in terms of money spent, the Chamber is by far the most powerful lobby in Washington, DC, spending $770.6 million since 1998, over three times the amount spent by General Electric, the second-largest spender. At the same time, the Chamber has reinforced its lobbying power by becoming one of the largest conduits of election-related “independent expenditures,” spending over $32.8 million on Federal elections in 2010. The Chamber sponsors the Institute for Legal Reform, which has spearheaded the campaign for tort “reform,” making it more difficult for average people who have been injured, assaulted, or harmed to sue the responsible corporations. Along with well over a dozen legal foundations, the Chamber has also helped shape the powerful “business civil liberties” movement that has been a driving force behind the Citizens United decision and other judicial actions that have handcuffed regulators and prevented Congress from putting common-sense checks on corporate power. (Cray)

It is clear from the above that the climate change disinformation campaign is only one element in an organized effort of corporations and free market fundamentalists foundations to limit the power of citizen movements to protect human health and the environment when these movements threaten corporate profits or unregulated markets.

Urgent Call to Climate Journalists Around The World: Research Concludes You Are Tragically Failing to Cover Climate Change Issues Through An Ethical and Justice Lens


Research conducted by Widener University Commonwealth Law School and the University of Auckland concludes that national debates about climate change policies and the press coverage of these issues are for the most part ignoring the obvious ethical and moral problems both with how nations are justifying climate change commitments and the arguments of climate change policy opponents at the national level. (See under “lessons learned.”) This is so despite the fact that:

(a)  It is impossible for a nation to think clearly about climate policy until the nation takes a position on two ethical issues: (1) what warming limit the nation is seeking to achieve through its policy, and (d) what is the nation’s fair share of safe global emissions. These are ethical issues that can’t be decided through economic or scientific analysis alone.

(b) Climate change policy making raises numerous ethical issues that arise in policy formulation. (See below)

(c) Ethical arguments made in response to the arguments of climate change policy arguments are often the strongest arguments that can be made in response to the claims of climate  policy opponents because most arguments made by opponents of climate policies fail  to pass minimum ethical scrutiny.

(d) Climate change more than any other environmental problem has features that scream for attention to see it fundamentally as a moral, ethical, and justice issue. These features include: (a) It is a problem overwhelmingly caused by high-emitting nations and individuals that is putting poor people and nations who have done little to cause the problem at greatest risk, (b) the harms to the victims are potentially catastrophic losses of life or the destruction of ecosystems on which life depends, (c) those most at risk usually can’t petition their own governments for protection, their best hope is that high emitters of ghgs will respond to their moral obligations to not harm others, and, (d) any solution to the enormous threat of climate change requires high emitting nations to lower their ghg emissions to their fair share of safe global emissions, a classic problem of distributive justice.

Our research has discovered that most journalists and national debates about climate policies around the world  have largely ignored the numerous ethical issues that arise in climate policy formation and instead usually have narrowly responded to the arguments of the opponents of climate policy which have almost always been variations of claims that climate change policies should be opposed because: (a) they will harm national economic interests, or (b) there is too much scientific uncertainty to warrant action.

Yet numerous issues arise in climate change policy formation for which ethical and moral considerations are indispensable to resolve these issues and moral arguments about these issues are by far the strongest responses to arguments on these issues usually made by opponents of climate policies. The issues include:

  • Can a nation justify its unwillingness to adopt climate change policies primarily on the basis of national economic interest alone?
  • When is scientific uncertainty an ethically acceptable excuse for non-action for a potentially catastrophic problem like climate change given that waiting until the uncertainties are resolved makes the problem worse and more difficult to solve?
  • Should proponents or opponents of climate change policies have the burden of proof to scientifically demonstrate that climate change is or is not a threat before climate change policies are in enacted?
  • What level of proof, such as, for instance, 95% confidence levels or the balance of the evidence, is needed to demonstrate climate change is a threat that warrants policy responses?
  • What amount of climate change harm is it ethically acceptable for a nation to impose on those nations or people outside their jurisdiction who will be harmed without their consent?
  • How aggressive should a nation be in achieving carbon neutrality?
  • Do high emitting nations have an ethical responsibility to reduce their ghg emissions as dramatically and quickly as possible or is their responsibility limited to assuring that their ghg emissions are no greater than their fair share of safe global emissions?
  • How transparent should a nation be in explaining the ethical basis for national ghg commitments particularly in regard to sufficiency of the ambition and fairness of the national commitments?
  • To what extent does a nation’s financial ability to reduce ghg emissions create an ethical obligation to do so?
  • What are the rights of potential victims of climate change to consent to a nation’s decision to delay national action on the basis of national cost or scientific uncertainty?
  • Who gets to decide what amount of global warming is acceptable?
  • Who should pay for reasonable adaptation needs of victims of climate change?
  • Do high emitting nations and individuals have a moral responsibility to pay for losses and damages caused climate change to people or nations who have done little to cause climate change?
  • How should national ghg targets consider the per capita or historical emissions of the nation in establishing their national climate commitments?
  • How should a nation prioritize its climate change adaptation needs?
  • Who has a right to participate in a nation’s decision about funding and prioritizing domestic and foreign adaptation responses?
  • How does global governance need to be changed to deal with climate change?
  • What difference for climate change policy-making is entailed by the conclusion that climate change violates human rights?
  • If climate change violates human rights, can economic costs to polluting nations be be a relevant consideration in the development of national climate policy?
  • Can one nation condition its response to the threat of climate change on the actions or inaction of other nations?
  • Which equity framework should a nation follow to structure its response to climate change?
  • What principles of distributive justice may a nation consider in determining its fair share of safe global emissions?
  • What kind of crime, tort, or malfeasance is spreading disinformation about climate change science by those who have economic interests in resisting constraints on fossil fuel?
  • What are the ethical limits of economic reasoning about the acceptability of climate change policies?
  • What ethical issues arise from cap and trade or carbon taxing solutions  to climate change?
  • What is ethically acceptable climate change scientific skepticism, for instance should all climate skeptics be expected to subject their claims in peer-reviewed journals?
  • Can a politician avoid responsibility for taking action on climate change simply on the basis that he or she is not a climate change scientist?
  • What ethical obligations are triggered by potentially catastrophic but low probability impacts from climate change and who gets to decide this?
  • What are the ethical limits to using cost-benefit analyses as a prescriptive guide to national climate policies?
  • What responsibility do high emitting nations have for climate refugees?
  • When are potential adverse environmental impacts of low emitting ghg technologies such as solar and wind a valid excuse for continuing to use high emitting ghg fossil fuel technologies?
  • Who gets to decide whether geo-engineering techniques which could lessen the adverse impacts of climate change are acceptable as long as these techniques could also create potential previously unexperienced environmental impacts?
  • What are the ethical and moral responsibilities of sub-national governments, businesses, organizations and individuals for climate change?
  • Can poor nations which have done little to cause climate change justify non-action on climate change on the basis of their lack of historical responsibility for climate change if some citizens or entities in the country are emitting high amounts of ghgs?
  • Do poor low-emitting nations have any moral responsibility for climate change and what is it?
  • When should a nation be bound by provisions of international law relevant to climate change including provisions in the United Nations Framework Convention on Climate Change that they agreed to such as the “no-harm,” and “precautionary? principles and the duty of developed nations to take the lead on climate change?
  • To what extent should stakeholder groups that advise governments on climate policies be gender and minority representative?

Obama Implicitly Acknowledges the Enormous Damage Caused By the Fossil Fuel Corporate Funded Climate Change Disinformation Campaign and Its Political Mercenaries

obama alaska

During his speech on August 31 in Alaska, President Obama not only spoke about the enormity of the climate change threat and the urgency of strong action, he also acknowledged that the United States has responsibility for causing the problem. He said:

I’ve come here today, as the leader of the world’s largest economy and its second largest emitter, to say that the United States recognizes our role in creating this problem, and we embrace our responsibility to help solve it. 

He spoke in clear terms about the enormity of the climate change threat:.

Our understanding of climate change advances each day.  Human activity is disrupting the climate, in many ways faster than we previously thought.  The science is stark.  It is sharpening.  It proves that this once-distant threat is now very much in the present. But the point is that climate change is no longer some far-off problem.  It is happening here.  It is happening now.  Climate change is already disrupting our agriculture and ecosystems, our water and food supplies, our energy, our infrastructure, human health, human safety — now.  Today.  And climate change is a trend that affects all trends — economic trends, security trends.  Everything will be impacted.  And it becomes more dramatic with each passing year. 

But if those trend lines continue the way they are, there’s not going to be a nation on this Earth that’s not impacted negatively.  People will suffer.  Economies will suffer.  Entire nations will find themselves under severe, severe problems.  More drought; more floods; rising sea levels; greater migration; more refugees; more scarcity; more conflict.

If we were to abandon our course of action, if we stop trying to build a clean-energy economy and reduce carbon pollution, if we do nothing to keep the glaciers from melting faster, and oceans from rising faster, and forests from burning faster, and storms from growing stronger, we will condemn our children to a planet beyond their capacity to repair:  Submerged countries.  Abandoned cities.  Fields no longer growing.  Indigenous peoples who can’t carry out traditions that stretch back millennia.  Entire industries of people who can’t practice their livelihoods.  Desperate refugees seeking the sanctuary of nations not their own.  Political disruptions that could trigger multiple conflicts around the globe.

President Obama also acknowledged that because nations have delayed in taking meaningful climate action, the world is running out of time to prevent catastrophic warming. More specifically he said:

On this issue, of all issues, there is such a thing as being too late. That moment is almost upon us.

And so President Obama admitted that: (a) climate change is a civilization challenging problem with dire potential consequences for nations and vulnerable people around the world, (b) the world is running out of time to prevent catastrophic warming, and, (c) the United States has responsibility for causing the problem.

The United States is not only responsible for the current crisis because, as President Obama noted, it is the second highest emitter of ghg in the world behind China,  it has historically emitted much more ghgs into the atmosphere than any other country including China, it is currently near the top of all nations in per capita ghg emissions, and the US has been responsible more than any other developed nation for the failure of the international community to adopt meaningful ghg emissions reduction targets from the beginning of international climate negotiations in 1990 until the Obama administration. (For a detailed description of the blocking role that the United States has played in international climate negotiations since 1990 until the Obama administration, See Brown, 2002, American Heat; Ethical Problems the US Response to Global Warming, and Brown, 2013,  Climate Chang Ethics: Navigating the Perfect Moral Storm)

In the Alaska speech, President Obama did not discuss the forces in the United States that have successfully undermined proposals for serious US climate change policies, matters which have been extensively discussed here under the category of “climate change disinformation campaign.”  Since the mid-1980s a well-funded  climate change disinformation campaign has successfully fought against US climate change policies. (For a discussion of the climate change disinformation campaign see, for example: The Climate Change Disinformation Campaign: What Kind Of Crime Against Humanity, Tort, Human Rights Violation, Malfeasance, Transgression, Villainy, Or Wrongdoing Is It? Part One: Is The Disinformation Campaign a Crime Against Humanity or A Civil Tort? ) This campaign has largely been funded by fossil fuel companies and free-market fundamentalists foundations although recently it has been difficult to track the funding. (See, New Study Concludes That Tracking Funding Of The Ethically Abhorrent Climate Disinformation Campaign Is Now Impossible)

As we have documented in numerous articles on the disinformation campaign on this website, although responsible scientific skepticism is necessary for science to advance, the climate change disinformation campaign has been involved not in the pursuit of responsible scientific skepticism but in tactics that are morally reprehensible including: (a) telling lies about mainstream climate scientific evidence or engaging in reckless disregard for the truth, (b) focusing on unknowns about climate science while ignoring settled climate change science, that is cherry-picking the evidence, (c) creating front groups and Astroturf groups that hide the real parties in interest behind claims, (d) making specious claims about “good science”, (e) manufacturing science sounding claims about climate change by holding conferences in which claims are made and documents are released that have not been subjected to scientific peer-review, and (d) cyber bullying journalists and scientists. These tactics are not responsible scientific skepticism but disinformation.

In the late 1980s, the European Union proposed that all developed countries should accept binding ghg emissions reductions targets. These targets would have likely been agreed to in the United Nations Framework Convention on Climate Change if the United States did not oppose them. The  United States virtually standing alone prevented the inclusion of binding targets in the treaty which was finalized in 1992 and ratified by the US in that same year. During the next 20 years, the US continued to block a meaningful global solution to climate change while being one of only a handful of nations that did not ratify the Kyoto Protocol, a treaty in which most developed countries accepted a ghg reduction target.

During this time, the climate change disinformation campaign also successfully prevented enactment of meaningful US domestic climate change laws and policies.

For the last several decades, US media has largely failed to cover the fact that the longer the world waits to make significant reductions in ghgs, the more difficult the problem becomes to solve. In this regard, the staggering enormity of the current challenge to the world to prevent dangerous climate change is rarely commented on in the US media despite the fact the 25 year delay in facing this problem has now made the  problem a civilization challenging problem.  For instance, James Hansen in a recent affidavit submitted in a legal proceeding against the State of Oregon asserted that the world must now reduce ghg emissions at a rate of 6% per year to avoid dangerous climate change. Yet as Hansen notes, if the world began to phase out of fossil fuel in 2005 the rate of reductions needed would only be 3.5% while waiting until 2020 will require a 15% reduction per year. Thus the delay in confronting climate change that is attributable to a large extent to the climate change disinformation campaign and its political mercenaries has made the problem much more difficult to solve with the result that harsh climate change impacts are much more likely. Because the harshest impacts from climate change will likely be experienced by some of  the world’s poorest people in Africa,Southeast Asia, and other parts of the world, the damage caused by the climate change disinformation campaign may become a global catastrophe.

And so the world is now facing a civilization challenging problem entailed by the need to rapidly reduce greenhouse gases to avoid catastrophic climate change.

Although President Obama has announced administrative measures that would begin to reduce US ghg emissions, these measures are now being intensely fought by the climate change disinformation campaign and its political representatives and the Obama commitments still don’t represent the US fair share of safe global ghg emissions. In fact, in his August 31 speech, President Obama said after describing his climate initiatives: “But we’re not moving fast enough.”   And now it may be too late to prevent huge climate change induced harms because the world has lost 25 years in reducing the threat of climate change in no small measure due to the United States opposition to a meaningful global solution.

President Obama’s August 31 speech in Alaska implicitly acknowledged this conclusion. Yet the US media largely continues to fail to cover the enormous damage that has been caused by the delay in confronting human-induced warming  .

Obama’s Laudable Speech Fails to Communicate Policy Implications of The Moral Dimensions of Climate Change.

obama clean power

When US President Obama announced revised regulations on reducing carbon dioxide emissions from US power plants on August 3, 2015 in a laudable speech supporting the new rules,  as he predicted opponents of US climate change policy strongly attacked the new rules on grounds that they would wreck the US economy, destroy jobs, and raise electricity prices.  Although President Obama defended the new rules on the basis that they were necessary to prevent dangerous climate change, that time was running out to do so, and that the rules would protect human health of US citizens, the speech failed to develop some of the obvious profound implications for climate policy of the conclusion that climate change is a moral problem, although President Obama did assert twice in the speech that climate change is a moral problem.

Although the Obama speech has rightly been praised  by those who believe the US must take strong action on climate change, his speech did not acknowledge that:

  • US ghg emissions are harming and seriously threatening hundreds of millions of people outside the United States. There was no mention in the speech how US ghg emissions were harming others around the world.
  • Those who are most vulnerable to climate change have done almost nothing to cause the existing threats to them.
  • Those who are most vulnerable to climate change can do little to protect themselves, their best hope is that high emitting nations, sub-national governments, organizations, entities, and individuals will respond to their moral responsibilities to reduce the threat of climate change.
  • If climate change is a moral problem, the US may not base its climate change policies on US interests alone, it must respond to its obligations to not harm others outside the United States. Therefore costs to the US economy alone may not be used to justify failure to reduce US ghg emissions.
  • The United States must reduce its ghg emissions to its fair share of safe global emissions, a fact which leads to the conclusion that the new rules for power plants are still not stringent enough in light of the fact that the Intergovernmental Panel on Climate Change has determined that developed countries must reduce their ghg emissions by a minimum of  25% to 40% by 2020 to prevent dangerous climate change and the new rule will only achieve 32% reduction by 2030 coupled with the added fact that any reasonable interpretation of what equity requires of the United States would require the US to be closer to the 40% reduction by 2020 and surely reduce US ghg emissions well in excess of 40% by 2030.
  • One of the reasons the world is now running out of time to prevent dangerous climate change is because fossil fuel companies and their allies in the US Congress has prevented the United States from taking serious action on climate change since 1992 when the George H. W Bush administration agreed in the United Nations Framework Convention on Climate Change that the United States should adopt policies and measures to prevent dangerous anthropocentric interference on climate change on the basis of equity and common but differentiated responsibilities. Thus the United States, more than any other developed country, has been responsible for the disastrous 30 year delay in formulating a serious global response to climate change, while delays make the problem harder and more expensive to solve and increase the likelihood of triggering dangerous climate change.
  • The United States is more responsible for raising atmospheric concentrations of greenhouse gas concentrations to 400 ppm CO2 equivalent in the atmosphere  than any country and has among the highest per capita ghg emissions as any country in the world.
  • The climate change opposition in the United States has successfully prevented the United States from adopting policies that would have significantly reduced US emissions on the basis of scientific uncertainty despite the fact that the United States agreed in the 1992 United Nations Framework Convention on Climate Change to not use scientific uncertainty as an excuse for not reducing its ghg emissions to safe levels.
  • Those nations who have consistently emitted ghgs above their fair share of safe global ghg emissions are responsible for the reasonable adaptation costs and damages of poor nations and people who have not caused climate change.These responsibilities are required both by basic ethics and justice and international law. These financial obligations will far exceed hundreds of billions of dollars per year.

Why the US Academy of Science and the Royal Academy’s Easy To Understand Report On Climate Change Science Has Ethical Significance

national academy


The National Academy of Sciences and its British counterpart, the Royal Society, have published  Climate Change: Evidence and Causes, a very easy to understand primer on the science of greenhouse-driven global warming. Although there is not a lot new in this report as a matter of science, it makes the strong scientific consensus on human-induced climate change that has existed for some time clearer and more accessible for non-scientists particularly on the major issues that need to be understood by policy-makers and interested citizens.  The report is written in simple language and filled with pictures and graphs which illustrate why almost all mainstream scientists actually engaged in climate change science are virtually certain that human activity is causing very dangerous climate change.

This report is ethically significant because:

a. It is a report of two of the most prestigious scientific institutions in the world, namely US National Academy of Sciences and the British Royal Society. Because of the prestige of both of the institutions writing this report, those opposing actual climate change have an ethical duty to acknowledge that the scientific basis supporting action on climate change is entitled to respect. They cannot reasonably claim that there is no strong scientific basis for policy action on climate change or even worse that climate change science is a “hoax.”  Which institutions have made claims that humans are engaged in dangerous behavior has ethical significance. If, for instance, someone is told by an expert in toxicology that chemicals he or she is discharging into a water supply will kill people, he or she has more of an ethical duty to stop discharging the chemicals until the issue of toxicology issues are resolved than they would if the claim about poisoning came from a religious leader or a tax accountant. When claims about danger are made by world-class scientific experts, as a matter of ethics, the burden of proof shifts to those potentially harming others to show that their behavior is not dangerous.

Skepticism in climate science should still be encouraged, but skeptics must play by the rules of science including: (a)  subjecting all claims contradicting the mainstream scientific view on climate change to peer-review, (b) subjecting claims that humans are not causing dangerous climate impacts to review by scientific institutions that have sufficient broad interdisciplinary expertise among its members to review such claims against all the contrary evidence from all relevant scientific disciplines, and (c) acknowledging all the contradictory evidence. Given the enormity of harms to citizens around the world and future generations predicted by mainstream scientists, those who seek to undermine proposed climate change policies on scientific certainty grounds should be understood to have the burden of proof to show by high levels of proof that human-induced climate change is not dangerous.

b. The report includes clear explanations of the scientific evidence in regard to specific justifications for not taking action on climate change very frequently made by those who oppose climate change policies. These justifications and responses to them include, for instance:

Justification 1

Scientists don’t know that recent climate change is largely caused by human activities?

Report says:

Scientists know that recent climate change is largely caused by human activities from an understanding of basic physics, comparing observations with models, and fingerprinting the detailed patterns of climate change caused by different human and natural influences.

Direct measurements of CO₂ in the atmosphere and in air trapped in ice show that atmospheric CO₂ increased by about 40 percent from 1800 to 2012. Measurements of different forms of carbon reveal that this increase is because of human activities.

Justification 2

The recent slowdown of warming means that climate change is no longer happening?

Report says:

No, recent weather is not evidence that warming is not happening. Since the very warm year 1998 that followed the strong 1997-1998 El Niño, the increase in average surface temperature has slowed relative to the previous decade of rapid temperature increases. Despite the slower rate of warming, the 2000s were warmer than the 1990s. A short-term slowdown in the warming of Earth’s surface does not invalidate our understanding of long-term changes in global temperature.

Justification 3

CO₂ is already in the atmosphere naturally, and so human emissions are not significant.

Report says:

Human activities have significantly disturbed the natural carbon cycle by extracting long-buried fossil fuels and burning them for energy, thus releasing CO₂ into the atmosphere.

 Justification 4

Variations in output from the sun have caused the changes in the Earth’s climate in recent decades.

Report says:

The sun provides the primary source of energy driving Earth’s climate system, but its variations have played very little role in the climate-changes observed in recent decades. Direct satellite measurements since the late 1970s show no net increase in the sun’s output while, at the same time, global surface temperatures have increased.

Justification 5

If the world is actually warming, some recent winters and summers would not have been so  cold?

Report says:

Global warming is a long-term trend, but that does not mean that every year will be warmer than the previous one. Day-to-day and year-to-year changes in weather patterns will continue to produce some unusually cold days and nights, and winters and summers, even as the climate warms.

Justification 6

A few degrees of warming is not cause for concern.

Report says:

Even though an increase of a few degrees in global average temperature does not sound like much, global average temperature during the last ice age was only about 4°C to 5°C (7 °F to 9 °F) colder than now. Global warming of just a few degrees will be associated with widespread changes in regional and local temperature and precipitation, as well as with increases in some types of extreme weather events.

These are only a few of the justifications that have been made by those denying responsibility to reduce the threat of climate change that are directly and clearly refuted in the report.

c. The report also has ethical significance because its so clear that policy makers cannot reasonably claim that there is no scientific evidence about the major issues of concern to the climate change scientific community. As we have explained on this website, policy-makers may not, as a matter of ethics, rely on their own uninformed opinion about climate change  science once they are informed by respectable scientific organizations that people and organizations  within their jurisdiction are likely harming others around the world. This responsibility to not rely upon their own uninformed opinions increases when there are easy to understand explanations from respected scientific institutions of the scientific basis for concluding that people within their jurisdiction are harming others. The new report from the US Academy of Sciences and the Royal Society is such a clear explanation.  And so government officials have a strong duty to go beyond their own uninformed opinion about whether humans are causing dangerous climate change. They must justify their refusal to act on strong, peer-reviewed scientific evidence that is accepted by mainstream scientific institutions that have the breadth of expertise to consider the interdisciplinary scientific issues that make up climate change science.

nw book advd.  Because politicians have an affirmative duty to rely upon mainstream scientific views in regard to human activities that could cause great harm until peer-reviewed science establishes that the mainstream view is erroneous, the press has a journalistic duty to help citizens understand the limitations of any politician’s views that opposes action on climate change on scientific grounds particularly when there are  easy to understand explanations of climate change science such as that in the new US National Academy and Royal Academy report. The new report will enable the press to fulfill its journalistic responsibilities by asking more precise and clearer questions of those who deny the mainstream scientific view.

For these reasons, the new report is ethically significant.
