This is the second in a three part series examining the ethical and justice issues discussed by the IPCC Working Group III in its 5th Assessment Report (AR5) . In the first entry in  this series we concluded that although the recent IPCC AR 5 Working Group III report is laudable improvement over prior IPCC reports in regard to identifying ethical and equity issues that should be considered in developing climate change policy, some criticisms are also warranted of how IPCC has articulated the significance and implications of the ethical, justice, and equity principles that should guide nations in developing climate change policies.

In short, we will argue improvement is possible in how IPCC deals with ethics, justice, and equity issues entailed by climate change policy-making despite very significant improvements on these matters in the AR5 report compared to prior IPCC reports.

In this entry we will examine several preliminary ethical and justice issues raised by the new IPCC Working Group III Chapter 3, on Social, Economic, and Ethical Concepts.  The last entry will continue the examination Chapter 3 and then turn to Chapter 4 on Sustainable Development and Equity.

As a preliminary matter, one of the challenges that IPCC faces in its mandate on of ethics and justice issues relevant to climate change policy-making is that it is not IPCC’s role to be prescriptive in deciding what governments should do. It’s mandate is to synthesize the extant social-economic and scientific literature for policy-makers. In this regard, the IPCC chapter on ethics said expressly:

This chapter does not attempt to answer ethical questions, but rather provides policymakers with the tools (concepts, principles, arguments, and methods) to make decisions. (IPCC, 2014.WG III, Ch. 3, pg. 10)

And so it is not IPCC’s role to do ethical analyses of policy issues that raise ethical questions. IPCC can, however, distinguish between prescriptive and descriptive questions that arise in relevant socio-economic literature about climate policy-making, identify important ethical and justice issues that arise in this literature, where there is a consensus on ethics and justice issues in the relevant literature describe the consensus position, where there is no consensus on ethical and justice issues describe the range of reasonable views on these issues, and identify hard and soft law legal principles relevant to how governments should resolve ethical and justice issues that must be faced by policy-makers.

There are several subjects in climate change policy-making which raise important ethical and justice issues. They include policy judgements about:

  1. how much warming will be tolerated, a matter which is implicit but rarely identified when nations make ghg emissions reduction commitments,
  2. any nation’s fair share of safe global emissions, matters which are referred to by the IPCC usually as burden-sharing or effort-sharing considerations and a matter taken up in chapter 4 of IPCC, Working Group III chapter on sustainability and equity,
  3. any nation’s responsibility for funding reasonable adaptation and compensation for losses and damages for those who are harmed by climate change,
  4. when a nation is responsible for its ghg emissions given differences in historical and per capita emissions among nations,
  5. responsibility for funding technology transfer to poor nations,
  6. how to evaluate the effects on and responsibilities to others of climate change technologies that are adopted in response to the threat of climate change, including such technologies as geo-engineering or nuclear power, for instance,
  7. who has a right to participate in climate change policy-making, a topic usually referred to under the topic of procedural justice,
  8. the policy implications of human rights violations caused by climate change,
  9. the responsibility of not only nations but subnational governments, entities, organizations, and individuals for climate change,
  10. when economic analyses of climate change policy options can prescribe or limit national duties or obligations to respond to the threat of climate change,
  11. ethical and justice implications of decisions must be made in the face of scientific uncertainty,
  12. whether action or non-action of other nations is relevant to any nation’s responsibility for climate change,
  13. how to spend limited funds on climate change adaptation,
  14. when politicians may rely on their own uninformed opinion about climate change science,
  15. who is responsible for climate refugees and what their responsibilities are.

nw book advOn some of these issues, the recent IPCC report included a good summary of the extant ethical literature, on other issues important gaps in IPCC’s analysis can be identified, and lastly on a few of these issues, IPCC Working Group III is silent. IPCC reports cannot be expected to be exhaustive on these matters and therefore gaps and omissions in the IPCC reports in regard to ethics and justice issues relevant to policy-making is not necessarily a criticism of IPCC and is here pointed out only for future consideration. In fact, IPCC’s work on the ethical limits of economic arguments is a particularly important contribution to the global climate change debate. What is worthy of criticism, however, is if IPCC’s conclusions on guidance for policy-makers is misleading on ethics and justice issues.

II. Ethical Issues Raised by Economic Arguments About Climate Policy

Perhaps the most important practical ethical and justice issues raised by Working Group III’s work on ethics is its conclusions on the ethical and justice limitations of economic analyses of climate change policy options. This topic is enormously practically important because nations and others who argue against proposed climate change policies usually rely on various economic arguments which often completely ignore the ethical and justice limitations of these arguments (In the case of the United States, see Brown, 2012.) Because most citizens and policy-makers have not been trained in spotting ethically dubious claims that are often hidden in what appear at first glance to be “value-neutral” economic arguments, IPCC’s acknowledgement of the ethical limitations of economic arguments is vitally important.  It is also practically important because the first four IPCC reports, although not completely ignoring all ethical and justice problems with economic arguments about climate change policies, failed to examine the vast majority of ethical problems with economic arguments against climate change policies while making economic analyses of climate change policies the primary focus of Working Group III’s work thereby  leaving the strong impression that economic analyses, including but not limited to cost-benefit analyses, is the preferred way to evaluate the sufficiency of proposed climate change policies.  On this matter, the AR5 report has made important clarifications.

The AR5 III report included a section on this very issue entitled: Economics, Rights, and Duties which we reproduce here it  its entirety because of its importance to this discussion,  followed by comments in bold italics:

Economics can measure and aggregate human wellbeing, but Sections 3.2, 3.3 and 3.4 explain that wellbeing may be only one of several criteria for choosing among alternative mitigation policies.

Other ethical considerations are not reflected in economic valuations, and those considerations may be extremely important for particular decisions that have to be made. For example, some have contended that countries that have emitted a great deal of GHG in the past owe restitution to countries that have been harmed by their emissions. If so, this is an important consideration in determining how much finance rich countries should provide to poorer countries to help with their mitigation efforts. It suggests that economics alone cannot be used to determine who should bear the burden of mitigation.

What ethical considerations can economics cover satisfactorily? Since the methods of economics are concerned with value, they do not take into account of justice and rights in general. However, distributive justice can be accommodated within economics, because it can be understood as a value: specifically the value of equality. The theory of fairness within economics (Fleurbaey, 2008) is an account of distributive justice. It assumes that the level of distributive justice within a society is a function of the wellbeings of individuals, which means it can be reflected in the aggregation of wellbeing. In particular, it may be measured by the degree of inequality in wellbeing, using one of the standard measures of inequality such as the Gini coefficient (Gini, 1912), as discussed in the previous section. The Atkinson measure of inequality (Atkinson, 1970) is based on an additively separable social welfare function (SWF), and is therefore particularly appropriate for representing the prioritarian theory described in Section 3.4.6 . Furthermore, distributive justice can be reflected in weights incorporated into economic evaluations as Section 3.6 explains.

Simply identifying the level of inequality using the Gini Index does not assure that the harms and benefits of climate change policies will be distributed justly. For that a theory of just distribution is needed. The Gini index is also at such a level of abstraction that it is very difficult to use it as a way of thinking about the justice obligations to those most vulnerable to climate change. Even if there is strong economic equality in a nation measured by the Gini index, one cannot conclude that climate change policies are distributively just.

Economics is not well suited to taking into account many other aspects of justice, including compensatory justice. For example, a CBA might not show the drowning of a Pacific island as a big loss, since the island has few inhabitants and relatively little economic activity. It might conclude that more good would be done in total by allowing the island to drown: the cost of the radical action that would be required to save the island by mitigating climate change globally would be much greater than the benefit of saving the island. This might be the correct conclusion in terms of overall aggregation of costs and benefits. But the island’s inhabitants might have a right not to have their homes and livelihoods destroyed as a result of the GHG emissions of richer nations far away. If that is so, their right may override the conclusions of CBA. It may give those nations who emit GHG a duty to protect the people who suffer from it, or at least to make restitution to them for any harms they suffer.

Even in areas where the methods of economics can be applied in principle, they cannot be accepted without question (Jamieson, 1992; Sagoff, 2008). Particular simplifying assumptions are always required, as shown throughout this chapter. These assumptions are not always accurate or appropriate, and decision‐makers need to keep in mind the resulting limitations of the economic analyses. For example, climate change will shorten many people’s lives. This harm may in principle be included within a CBA, but it remains highly contentious how that should be done. Another problem is that, because economics can provide concrete, quantitative estimates of some but not all values, less quantifiable considerations may receive less attention than they deserve.

This discussion does not adequately capture serious ethical problems with translating all values into monetary units measured by willingness to pay or its surrogates nor that such transformation may greatly distort ethical obligations to do no harm into changes in commodity value.

The extraordinary scope and scale of climate change raises particular difficulties for economic methods (Stern, forthcoming). First, many of the common methods of valuation in economics are best designed for marginal changes, whereas some of the impacts of climate change and efforts at mitigation are not marginal (Howarth and Norgaard, 1992). Second, the very long time scale of climate change makes the discount rate crucial at the same time as it makes it highly controversial (see Section 3.6.2 ). Third, the scope of the problem means it encompasses the world’s extremes of wealth and poverty, so questions of distribution become especially important and especially difficult. Fourth, measuring non‐market values—such as the existence of species, natural environments, or traditional ways of life of local societies—is fraught with difficulty. Fifth, the uncertainty that surrounds climate change is very great. It includes the likelihood of irreversible changes to societies and to nature, and even a small chance of catastrophe. This degree of uncertainty sets special problems for economics. (Nelson, 2013) (IPCC, 2014.WG III, Ch. 3, pg. 12-13)

Again this discussion does not adequately describe the ethical problems with economic determinations of all values. In fact it leaves the impression that if non-market values can be discovered the problems of transforming all values to commodity values are adequately dealt with.

Chapter 3, also includes additional statements about the ethical limits of economic reasoning sprinkled throughout the chapter. They include:

1. Most normative analyses of solutions to the climate problem implicitly involve contestable ethical assumptions.(IPCC, 2014. WG III, Ch. 3, pg.10)

2. However, the methods of economics are limited in what they can do. They can be based on ethical principles, as Section 3.6 explains. But they cannot take account of every ethical principle. They are suited to measuring and aggregating the wellbeing of humans, but not to taking account of justice and rights (with the exception of distributive justice − see below), or other values apart from human wellbeing. (IPCC, 2014.WG III, Ch. 3, pg. 24)

And so Chapter 3 of the IPCC report contains a number or clear assertions  about the ethical limitations of economic arguments. However there are important gaps missing from this analysis. Also several sections of Chapter 3 that can be interpreted as claims that policy makers are free to choose economic reasoning as justification for climate policies. That is, some of the text reads as if a policy-maker is free to choose whether to base policy  on economic or ethical and justice considerations, choosing between these two ways of evaluation is simply an option. Some of these provisions follow with responses in italics

Chapter 3 page 6 says:

Many different analytic methods are available for evaluating policies. Methods may be quantitative (for example, cost‐benefit analysis, integrated assessment modeling, and multi‐criteria analysis) or qualitative (for example, sociological and participatory approaches). However, no single best method can provide a comprehensive analysis of policies. A mix of methods is often needed to understand the broad effects, attributes, trade‐offs, and complexities of policy choices; moreover, policies often address multiple objectives  (IPCC, 2014.WG III, Ch. 3, pg. 6)

Although economic analyses can provide policy-makers with valuable information such as which technologies will achieve ethically determined goals at lowest cost, thereby providing criteria for making remedies cost-effective, there are serious ethical problems with cost-benefit analyses used prescriptively to set emissions reductions targets. Some of these are alluded to in IPCC Chapters 3 and 4, others are not acknowledged. Because of the prevalence of cost-benefit justifications for climate change policies, future IPCC reports could make a contribution by identifying all of the ethical issues raised by cost-benefit analyses.

 Any decision about climate change is likely to promote some values and damage others. These may  be values of very different sorts. In decision making, different values must therefore be put together or balanced against each other. (IPCC, 2014. WG III, Ch. 3, pg. 6)

This provision can be understood as condoning a consequentialist approach to climate policy that fails to acknowledge deontological limits. Since when any nation makes policy on climate change it affects poor people and vulnerable nations around the world, there are serious procedural justice issues which go unacknowledged in this section and,  for the most part, all throughout Chapter 3. Nowhere does the chapter acknowledge that when a climate policy is  under development at the national level,  nations have no right to compare costs to them of implementing policies  with the harms to others that have not consented to the method of valuation being used to determine quantitative value.

Ideally, emissions should be reduced in each place to just the extent that makes the marginal cost of further reductions the same everywhere. One way of achieving this result is to have a carbon price that is uniform across the world; or it might be approximated by a mix of policy instruments (see Section 3.8 ). (IPCC, 2014.WG III, Ch. 3, pg. 26)

This statement fails to acknowledge that emissions reductions amounts should be different in different places according to well accepted principles of distributive justice. Although other sections of the chapter acknowledge that responsibility for climate change is a matter of distributive justice, this section and others leave the impression that climate policy can be based upon economic efficiency grounds alone. The way to cure this problem is to continue to reference other sections that recognize ethical limits in setting policy on the basis of efficiency.

(IPCC, 2014.WG III, Ch. 3, pg. 6)

Since, for efficiency, mitigation should take place where it is cheapest, emissions of GHG should be reduced in many developing countries, as well as in rich ones. However, it does not follow that mitigation must be paid for by those developing countries; rich countries may pay for mitigation that takes place in poor countries. Financial flows between countries make it possible to separate the question of where mitigation should take place from the question of who should pay for it. Because mitigating climate change demands very large‐scale action, if put in place these transfers might become a significant factor in the international distribution of wealth. Provided appropriate financial transfers are made, the question of where mitigation should take place is largely a matter for the  economic theory of efficiency, tempered by ethical considerations. But the distribution of wealth is amatter of justice among countries, and a major issue in the politics of climate change (Stanton, 2011). It is partly a matter of distributive justice, which economics can take into account, but compensatory justice may also be involved, which is an issue for ethics. (Section 3.3).(IPCC, 2014.WG III, Ch. 3, pg. 26)

There are a host of  potential ethical problems with mitigation taking place in one part of the world to satisfy the ethical obligations of a nation in another part of the world which is emitting above its fair share of safe global emissions that are not mentioned in this article. Included in these problems are:

  • Environmental Sufficiency. There are many technical challenges in assuring that a project in one part of the world that seeks to reduce ghg by an amount that otherwise would be required of a polluter will actually succeed in achieving the reductions particularly when the method of reduction is reliant on biological removal of carbon.
  • Permanence. Many proposed projects for reducing carbon in one part of the world to offset reductions ethically required in another part of the world raise serious questions about whether the carbon reduced by the project will stay out of the atmosphere forever, a requirement that is required to achieve the environmental equivalence to ghg emissions reductions that would be achieved at the source.
  • Leakage. Many proposed projects used to offset emissions reductions of high-emitters raise serious questions about whether carbon reduced by a project at one location will result in actual reductions in emissions because the activity which is the subject of the offset is resumed at another location.
  • Additionality. A project that is proposed in another part of the world to offset emissions reductions of a high-emitting entity may not be environmentally effective if the project would have happened anyway for other reasons.
  • Allowing Delay In Investing In New Technology. The ability to rely on a cheaper emissions reductions project in another part of the world as a substitute of reducing emissions creates an excuse for high-emitting entities to delay investment in technologies that will reduce the pollution load. This may create a practical problem when emissions reductions obligations are tightened in the future. 

Chapter 3 also treats other important ethical issues that arise in climate change policy formation. They include:

3.3 Justice, equity and responsibility,

3.3.1 Causal and moral responsibility

3.3.2 Intergenerational justice and rights of future people

3.3.3 Intergenerational justice: distributive justice

3.3.4 Historical responsibility and distributive justice

3.3.5 Intra‐generational justice: compensatory justice and historical responsibility

3.3.6 Legal concepts of historical responsibility

3.3.7 Geoengineering, ethics, and justice

3.4 Values and wellbeing

3.4.1 Non‐human values

3.4.2 Cultural and social values

3.4.3 Wellbeing

3.4.4 Aggregation of wellbeing

3.4.5 Lifetime wellbeing

3.4.6 Social welfare functions

3.4.7 Valuing population

III. Some Additional Gaps In Chapter 3

Some of the gaps in Chapter 3 on ethical issues raised by climate change policy-making include: (1) ethics of decision-making in the face of scientific uncertainty, (2) whether action or non-action of other nations affects a nation’s responsibility for climate change, (3) how to spend limited funds on climate change adaptation, (4) when politicians may rely on their own uninformed opinion about climate change science, and (5) who is responsible to for climate refugees and what are their responsibilities.

The last entry in this series will continue the analyses of IPCC  Chapter 3 on Social, Economic, and Ethical Concepts and Chapter 4 on Sustainability and Equity.

Five Common Arguments Against Climate Change Policies That Can Only Be Effectively Responded To On Ethical Grounds

climate  change moral

Ethics and climate has explained in numerous articles on this site why climate change policy raises civilization challenging ethical issues which have practical significance for policy-making. This article identifies five common arguments that are very frequently made in opposition to proposed climate change laws and policies that cannot be adequately responded to without full recognition of serious ethical problems with these arguments. Yet the national debate on climate change and its press coverage in the United States and many other countries continue to ignore serious ethical problems with arguments made against climate change policies. The failure to identify the ethical problems with these arguments greatly weakens potential responses to these arguments. These arguments include:

 1. A nation should not adopt climate change policies because these policies will harm the national economy.

This argument is obviously ethically problematic because it fails to consider that high emitting governments and entities have clear ethical obligations to not harm others.  Economic arguments in opposition to climate change policies are almost always arguments about self-interest that ignore strong global obligations. Climate change is a problem that is being caused mostly by high emitting nations and people that are harming and putting at risk poor people and the ecological systems on which they depend around the world. It is clearly ethically unacceptable for those causing the harms to others to only consider the costs to them of reducing the damages they are causing while ignoring their responsibilities to not harm others.

new book description for website-1_01 It is not only high emitting nations and corporations that are ignoring the ethical problems with cost-based arguments against climate change policies. Some environmental NGOs usually fail to spot the ethical problems with arguments made against climate change policies based upon the cost or reducing ghg emissions to the emitters. Again and again proponents of action on climate change have responded to economic arguments against taking action to reduce the threat of climate change by making counter economic arguments such as climate change policies will produce new jobs or reduce adverse economic impacts that will follow from the failure to reduce the threat of climate change.  In responding this way, proponents of climate change policy action are implicitly confirming the ethically dubious notion that public policy must be based upon economic self-interest rather than responsibilities to those who will be most harmed by inaction. There is, of course, nothing wrong with claims that some climate change policies will produce jobs, but such assertions should also say that emissions should be reduced because high-emitters of ghgs have duties and obligations to do so.

 

2. Nations need not reduce their ghg emissions until other high emitting nations also act to reduce their emissions because this will put the nation that reduces its emissions in a disadvantageous economic position.

Over and over again opponents of climate change policies at the national level have argued that high emitting nations should not act to reduce their ghg emissions until other high emitting nations also act accordingly. In the United States, for instance, it is frequently said that the United States should not reduce its ghg emissions until China does so.  Implicit in this argument  is the notion that governments should only adopt policies which are in their economic interest to do so.  Yet as a matter of ethics, as we have seen, all nations have a strong ethical duty to reduce their emissions to their fair share of safe global emissions and national economic self-interest is not an acceptable justification for failing to reduce national ghg emissions. Nations are required as a matter of ethics to reduce their ghg emissions to their fair share of safe global  emissions; they are not required to reduce other nations’ share of safe global emissions. And so, nations have an ethical duty to reduce their ghg emissions to their fair share of safe global emissions without regard to what other nations do.

3. Nations need not reduce their ghg emissions as long as other nations are emitting high levels of ghg because it will do no good for one nation to act if other nations do not act.

A common claim similar to argument 2 is the assertion nations need not reduce their ghg emissions until others do so because it will do no good for one nation to reduce its emissions while high-emitting nations continue to emit without reductions. It is not factually true that a nation that is emitting ghgs at levels above its fair share of safe global emissions is not harming others because they are continuing to cause elevated atmospheric concentrations of ghg which will cause some harm to some places and people than would not be experienced if the nation was  emitting ghg at lower levels. And so, since all nations have an ethical duty to reduce their ghg emissions to their fair share of safe global emissions, nations have a duty to reduce the harm that they are causing to others even if there is no adequate global response to climate change.

4.  No nation need act to reduce the threat of climate change until all scientific uncertainties about climate change impacts are resolved.

Over and over again opponents of climate change policies have argued that nations need not act to reduce the threat of climate change because there are scientific uncertainties about the magnitude and timing of  human-induced climate change impacts. There are a host of ethical problems with these arguments. First, as we have explained in detail on this website under the category of disinformation campaign in the index, some arguments that claim that that there is significant scientific uncertainty about human impacts on climate have been based upon lies or reckless disregard for the truth about mainstream climate change science. Second, other scientific uncertainty arguments are premised on cherry picking climate change science, that is focusing on what is unknown about climate change while ignoring numerous conclusions of the scientific community that are not in serious dispute. Third. other claims that there is scientific uncertainty about human induced climate change have not been subjected to peer-review. Fourth some arguments against climate change policies  on the basis of scientific uncertainty often rest on the ethically dubious notion that nothing should be done to reduce a threat that some are imposing on others until all uncertainties are resolved. They make this argument despite the fact that if high emitters of ghg wait until all uncertainties are resolved before reducing their ghg emissions:

  • It will likely be too late to prevent serious harm if the mainstream scientific  view of climate change is later vindicated;
  • It will be much more difficult to prevent catastrophic harm if nations wait, and
  • The argument to wait ignores the fact that those who will be harmed the most have not consented to be put at greater risk by waiting.

For all of these reasons, arguments against taking action to reduce the threat of climate change based upon scientific uncertainty fail to pass minimum ethical scrutiny.

5. Nations need only set ghg emissions reduction targets to levels consistent with their national interest.

Nations continue to set ghg emissions reductions targets at levels based upon their self-interest despite the fact that any national target must be understood to be implicitly a position on two issues that cannot be thought about clearly without considering ethical obligations. That is, every national ghg emissions reduction target is implicitly a position on : (a) a safe ghg atmospheric stabilization target; and (b) the nation’s fair share of total global ghg emissions that will achieve safe ghg atmospheric concentrations.

A position on a global ghg atmospheric stabilization target is essentially an ethical question because a global ghg atmospheric concentration goal will determine to what extent the most vulnerable people and the ecological systems on which they depend will be put at risk. And so a position that a nation takes on atmospheric ghg atmospheric targets is necessarily an ethical issue because nations and people have an ethical duty to not harm others and the numerical ghg atmospheric goal will determine how much harm polluting nations will impose on the most vulnerable.

Once a global ghg atmospheric goal is determined, a nation’s ghg emissions reduction target is also necessarily implicitly a position on the nation’s fair share of safe global ghg emissions, an issue of distributive justice and ethics at its core.

And so any national ghg emissions target is inherently a position on important ethical and justice issues and thus setting a national emissions reduction target based upon national interest alone fails to pass minimum ethical scrutiny.

An Ethical Analysis of Obama’s Climate Speech, the Adverse Political Reaction to It, and the Media Response.

 

aboma under water climate and obama

mcconnell_thumb Joe Manchin

 

On June 25th, President Obama gave a major speech on climate change in which he announced what his administration would do to reduce greenhouse gas (ghg) emissions in the United States. Although the US Congress has continued to fail to act on climate change since climate negotiations began in 1990, President Obama identified administrative actions that he would take that did not depend upon US congressional action. As we shall see, the speech was significant for some of the ethical issues touched upon in the speech.

As expected some US politicians vigorously attacked the speech on the basis that the announced actions would destroy jobs and the US coal industry. We now look at this speech, the political response to it, and the US media reaction through an ethical lens.

In light of the US’s strong moral duty to take action to reduce the threat of climate change that has been virtually ignored by most previous US leaders. many parts of this important speech are worthy of praise.

President Obama promised to use this authority under the federal Clean Air Act to reduce greenhouse gases from electric power plants. He also dismissed climate change skeptics as Flat Earthers and urged US citizens at all levels to take steps to reduce climate change causing emissions and push back against those who would work to undermine US policy to reduce the threat of climate change. He further announced  plans to double wind and solar power while increasing the use of renewable energy in federal facilities to 20 % in 7 years.  He also identified a number of policy responses to reduce energy demand with the goal of significantly reducing the waste of energy.

In response to climate skeptics he said:

So the question is not whether we need to act. The overwhelming judgment of science — of chemistry and physics and millions of measurements — has put all that to rest. Ninety-seven percent of scientists, including, by the way, some who originally disputed the data, have now put that to rest. They’ve acknowledged the planet is warming and human activity is contributing to it.

He also acknowledged some US responsibility to help developing nations transition to clean energy and announced a number of policy initiatives in support of this goal.

In regard to the the ethical responsibility of the United States to reduce the threat of climate change, President Obama said:

[A]s the world’s largest economy and second-largest carbon emitter, as a country with unsurpassed ability to drive innovation and scientific breakthroughs, as the country that people around the world continue to look to in times of crisis, we’ve got a vital role to play. We can’t stand on the sidelines. We’ve got a unique responsibility.

This statement is very significant for its ethical implications.  In fact, this is the strongest statement of any US President in regard to acknowledging that US policy on climate change can not solely be based upon US interests alone. That is, it is notable for its recognition of US responsibility to act on climate change. Thus, in addition to US interests in climate change policies, President Obama acknowledged that the United States has obligations, responsibilities, and duties to act. This fact has profound significance for US climate change policy.  It means, that the US must consider its obligations to others not to harm them through our ghg emissions. Yet, as we have seen over and over again, US climate change policies are usually debated in the United States as if only US interests count.

This speech also acknowledged that it is probably too late to avoid the need of nations to adapt to climate change’s adverse impacts.This is so because even if aggressive action it taken on climate change around the world, some adverse climate change impacts are inevitable. Notable in this regard was the speech’s acknowledgement that:

We’re going to need to give special care to people and communities that are unsettled by this transition — not just here in the United States but around the world.

And so, President Obama seems thus to acknowledge US obligations to help developing nations to adapt to climate change.

Another part of the speech with ethical significance is remarks about a new climate change treaty that was agreed to in Durban, South Africa that is to be completed in 2015 and come into effect in 2020. In this regard, President Obama said:

Two years ago, we decided to forge a new agreement beyond 2020 that would apply to all countries, not just developed countries. What we need is an agreement that’s ambitious — because that’s what the scale of the challenge demands. We need an inclusive agreement -– because every country has to play its part. And we need an agreement that’s flexible — because different nations have different needs.

This statement is of considerable ethical significance because it acknowledges that different nations have different responsibilities and needs in regard to climate change policies. This idea was agreed to by the United States but has largely been ignored. In ratifying the United Nations Framework Convention on Climate Change in 1992 under then president George H. W. Bush, the United States promised to reduce its ghg emissions based upon “equity” and “common but differentiated responsibilities” to prevent dangerous climate change. This  idea, which entails looking at the US response to climate change through the lens of distributive justice, has been almost completely ignored by the US Congress and former US presidents. It is also an idea that entails that the United States must reduce its emissions more aggressively than developing nations that have done significantly less to cause increasing atmospheric ghg concentrations.

This statement also implicitly acknowledges that all nations. including the United States, have an ethical duty to increase the ambitiousness of its ghg emissions reductions commitments in climate negotiations that are under discussion until 2015.

President Obama also acknowledged our ethical responsibility to future generations to reduce the threat of climate change when he said:

Our founders believed that those of us in positions of power are elected not just to serve as custodians of the present, but as caretakers of the future.  And they charged us to make decisions with an eye on a longer horizon than the arc of our own political careers. That’s what the American people expect. That’s what they deserve.

And so as a matter of ethics, President Obama acknowledged that the US has a special responsibility to act on climate change in response to our ethical obligations, not our national interests alone , in proportion to our responsibility as a matter of distributive  justice and our obligations to future generations  while at the same time assisting vulnerable developing nations to adapt to the inevitable adverse climate impacts that now can not be avoided.

earrh

President Obama also ended his speech with a call to recognize the sacred importance of protecting Earth by recalling the astonishment of the astronauts when they saw the Earth from outer space as they came around the moon for the first time.

For while we may not live to see the full realization of our ambition, we will have the satisfaction of knowing that the world we leave to our children will be better off for what we did.

“It makes you realize,” that astronaut said all those years ago, “just what you have back there on Earth.” And that image in the photograph, that bright blue ball rising over the moon’s surface, containing everything we hold dear — the laughter of children, a quiet sunset, all the hopes and dreams of posterity — that’s what’s at stake. That’s what we’re fighting for. And if we remember that, I’m absolutely sure we’ll succeed.

 And so as, a matter of ethics, Obama’s speech was laudable and historically significant in many respects. That is not to say, however, that the Obama speech cannot be criticized for some omissions in regard to the US’s ethical obligations for climate change. These omissions included: (a)  the lack of recognition that dependence on natural gas as a bridge fuel for reducing the US carbon footprint raises several ethical questions, a matter reviewed here in detail, (b) acknowledgment of the US special responsibility for climate change for its unwillingness to take action on climate change for over 20 years since it ratified the United Nations Framework Convention on Climate Change in 1992, see, The World Waits In Vain For US Ethical Climate Change Leadership As the World Warms, and, (c) failing to communicate the extreme urgency of quickly and significantly reducing ghg emissions in the next few years to give the world any hope of avoiding dangerous climate change, see, On the Extraordinary Urgency of Nations Responding To Climate Change on the Basis of Equity.  In this regard, Obama’s speech utterly failed to acknowledge the magnitude of the ghg emissions reductions that are  ethically required of the United States in the next decade.

And so, all in all, the Obama speech can be praised for its express recognition of many of the ethical ethical obligations entailed by climate change despite some quibbles about a few ethical issues not covered well.

As was expected, the political opposition in the US to the speech was rapid and intense. For instance Senate Minority Leader Mitch McConnell, R-Ky., said that Obama’s plan on climate change was was a “war on coal” and on jobs.

Senator Joe Manchin, D-WV, went further saying that the Obama climate plan was not just a “war on jobs” and a “war on West Virginia,” but also, a “war on America.”

imhoff

Senator James Inhofe, R-Ok, who has consistently claimed that the  mainstream scientific view on climate is a “hoax,” said the Obama plan will cost the US economy $400 billion a year while ranting about other aspects of the Obama climate plan.

The most frequent justifications for the strong opposition to the Obama climate plan have been the claimed severe economic harms to the US economy, lack of scientific certainty on adverse climate impacts, and the inability of the United States acting alone to prevent climate change.

As we have explained in considerable detail before, these excuses utterly fail to withstand minimum ethical scrutiny.

Economic harm arguments made in opposition to Obama’s climate plan, for instance, even if true, both fail to recognize the ethical obligations that the United States has to not harm others through our ghg emissions and to acknowledge the costs of not acting. US climate policy cannot be based upon US interests alone. The United States has obligations to others. In addition, economic arguments for not acting on climate change ignore obligations that nations have if they are creating human rights violations and duties entailed  by distributive justice. These are only a few of the ethical problems with economic arguments made in opposition to US climate change policies.  For a detailed ethical analyses of economic arguments made  in opposition to US climate change policies, see Ethicsandclimate.org index under Economics and Climate Ethics. 

Scientific certainty arguments made in opposition to climate change fail as a matter of ethics for a  host of reasons including the fact that almost all of the most prestigious scientific organizations in the world and the vast majority of scientists that do peer-reviewed science support the consensus view that has concluded that climate change is  a growing civilization challenging threat to people and ecological systems on which life depends around the world, uncertainty in these situations raises ethical questions about burdens and quantity of proof, those most vulnerable to climate change have not consented to be put at risk from climate change, and the longer the world waits to reduce the threat of  climate change the worse the  problem becomes. For detailed ethical analysis of scientific uncertainty arguments made in opposition to climate change, see Ethicsandclimate.org index under Scientific Uncertainty and Climate Ethics.

Arguments in opposition to action on climate change based upon the claim that the  United States  acting alone will not significantly reduce the threat of climate change fails any ethical test because all nations  have a duty to act to reduce their emissions to their fair share without regard to what other nations do. For detailed ethical analysis of this issue, see, Ethical Issues Raised By US Blue Dog Democratic Senators’ Opposition to Climate Legislation – When May a Nation Make Domestic GHG Reduction Commitments Contingent on Other Nations’ Actions

And so, the arguments made in opposition to the Obama speech fail to withstand  ethical scrutiny.

The US media response to the Obama speech and the political response thereto has once again completely ignored the ethical problems with the strong political opposition to the speech. As we have noted over and over again in regard to the US media coverage of the US response to climate change, the US press is utterly failing to cover ethical issues entailed by opposition to climate change policies in the United States. This is particularly true of economic and scientific uncertainty arguments made in opposition to proposed US climate change policies. Nor is the US press covering ethical issues entailed by the urgency and  magnitude of the need to reduce ghg emissions  given that the world is likely  running out of time to prevent warming of 2 degrees C, a warming amount which is widely believed could create rapid, non-linear climate change. For a discussion of this issue, see: On the Extraordinary Urgency of Nations Responding To What Equity Requires of Them In Their Responses to Climate Change.

One might ask why the US media is failing to cover the obvious ethical questions raised by climate change issues given that the ethical issues have profound consequences for climate change policy and climate change raises obvious civilization challenging ethical issues. We  might ask why the US press is failing to cover the ethical and justice issues entailed by climate change given that vulnerable countries around the world have been screaming for developed nations including the United States to respond in accordance with their ethical obligations. Is the US  press so connected to the economic interests of the United States, that it is blind to the US ethical obligations for climate change? If the US press has not been corrupted by the economic interests of the United States, the only plausible explanation for the US media’s failure to cover the  ethical issues raised by climate change is that the reporter’s covering climate  change don’t understand the civilization challenging ethical issues raised by climate change. If this is the explanation, there is a huge practical need to demand that the US press turn up the volume on the ethical dimensions of climate change.

Why Politicians May Not Ethically Rely on Their Own Uninformed Opinion About Climate Science and 10 Questions That The Press Should Ask Politicians About Climate Science In Light of This Responsibility.

Marco Rubio, a US Senator from Florida, recently said that he was not sure the climate change was human caused. This is one of the reasons why he’s unwilling to support US government action to reduce the threat of climate change.  Many other US politicians have also recently said they will not support legislation to reduce US greenhouse gas emissions because they are not convinced that climate change happening or is human-caused. In fact, 7 out of 8 Republican candidates for the US presidency proclaimed they didn’t believe that climate change was a problem. (Skeptical Science) When these politicians are asked about the basis for their positions on climate change, they almost always respond by saying such things as they “have heard that there is a disagreement among scientists” or similar responses that strongly suggest they have informed an opinion on climate change science without any understanding of the depth of the scientific evidence on which the scientific consensus view 0f climate change has been based. For instance, US politicians frequently assert that it is an open question whether humans are causing the undeniable warming that the Earth is experiencing, thus exposing ignorance of dozens of lines of independent robust evidence of human causation including attribution studies, finger print analyses,  strong evidence that correlates fossil fuel use to rising atmospheric concentrations of greenhouse gases, and other physical and chemical evidence.

Although ordinary individuals may have no duty to go beyond their own personal opinion about the science of climate change, government officials who have the power to enact policies that could present catastrophic harm to millions of people around the world may not as a matter of ethics justify their refusal to support policies to reduce the threat of climate change on the basis of their uninformed opinions on climate science. This is so because government officials, unlike ordinary citizens, have the power to prevent or minimize great harms to millions of people around the world that mainstream scientists have concluded that their constituents or governments that they represent are causing or contributing to. That is, a government officials have more responsibility than the average citizen to understand the state of climate change science because the government official can uniquely prevent harm that their constituents or governments are causing. And so, when government officials with the power to enact climate change policies are on notice that respectable scientific evidence supports the conclusion that their constituents or governments are likely causing great harm, they may not appeal to their uninformed opinion on climate science as justification for not taking action.


The government official is like the railroad official who has been told by employees who are in a position to know the location of the company’s trains that there is a runaway train hurtling toward a bus full of children that is stuck on the track, when the official has the ability to divert the train onto a track on which no humans will be harmed.

In the case of climate change, government officials should know that 97 of every 100 scientists that actually do peer-reviewed climate science research and in the  United States by the most prestigious scientific organizations including the US National Academy of Sciences that greenhouse gases coming from his constituents threaten catastrophic harm not only to his constituents but to millions of people around the world, most of whom have done little to cause climate change.

In the case of climate change, the US politician not only has the power, working with colleagues, to prevent great harm caused by his or her constituents, he or she has the responsibility to prevent his or her constituents from harming others outside United States. This responsibility was expressly agreed to by the United States when it ratified the United Nations Convention on Climate Change which contains the following acknowledgment of the US governments responsibility to prevent harm to those outside the United States in the convention’s Preamble:

Recalling also that States have, in accordance with the Charter of the United Nations and the principles of international law, the sovereign right to exploit their own resources pursuant to their own environmental and developmental policies, and the responsibility to ensure that activities within their jurisdiction or control do not cause damage to the environment of other States or of areas beyond the limits of national jurisdiction. (UNFCCC Preamble)

In the case of climate change, the people that will be harmed (those in our metaphorical bus) are not only the constituents of the politician but hundreds of millions of people around the world that have done little or nothing to cause climate change.

 

The vast majority of climate scientists and over 100 scientific organizations whose members have climate science expertise have concluded that humans are causing climate change and human-induced climate change creates catastrophic threats for the human race and particularly for hundreds of millions of poor people around the world who are most vulnerable to climate change impacts.  Although there are some differences among some mainstream scientists about some of the details of the consensus view, an open letter from the American Association for the Advancement of Science’s which was endorsed by 18 of the most prestigious scientific organizations in the United States summed up the nature of the scientific consensus as follows:

As you consider climate change legislation, we, as leaders of scientific organizations, write to state the consensus scientific view. Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver. These conclusions are based on multiple independent lines of evidence, and contrary assertions are inconsistent with an objective assessment of the vast body of peer- reviewed science. (AAAS 2009)

Though scientific consensus must always be open to responsible skepticism given: (a) the strength of the consensus on this topic, (b) the enormity of the harms predicted by the consensus view, (c) an approximately 30 year delay in taking action that has transpired since a serious climate change debate began in the United States in the early 1980s, (d)  a delay that has made the problem worse while making it more difficult to achieve ghg emissions reductions necessary to prevent dangerous climate change because of the steepness of reductions now needed, no politician can ethically justify his or her refusal to support action on climate change based upon a personal opinion that is not supported by strong scientific evidence that has been reviewed by scientific organizations with a wide breadth of interdisciplinary scientific expertise.  Because any further delay will make the climate change threat worse, US politicians have a duty to support policies that will reduce the threat of climate unless they can produce strong scientific evidence that has been fully vetted by respectable scientific institutions that climate change is not the threat entailed by the scientific consensus view.

In this situation the government official has a strong duty to go beyond his or her 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 one study in the context of thousands of other studies in climate change science. And so, government officials may not justify their refusal to act simply on the basis of  their personal opinion.

Because politicians have an affirmative duty to initially rely upon mainstream scientific views in regard to human activities that could cause great harm, the press has a journalistic duty to help citizens understand any politician’s views that oppose action on climate change policies on scientific grounds. The US press has almost always failed to probe the justifications of those opposing action on climate change on scientific grounds. For this reason, journalists should ask politicians that claim there is not sufficient scientific support for government action climate change the following questions:

1. What specific scientific references and sources do you rely upon to conclude that there is a reasonable scientific dispute about whether human actions are causing dangerous climate change?

2. Are you aware that the United States Academy of Sciences and almost all respected scientific organizations whose membership includes scientists  with expertise relevant to climate change science support the scientific consensus view that holds has that the planet is warming, that the warming is mostly human caused, and that harsh impacts from warming are very likely under business-as-usual?

3.  On what basis do you disregard the conclusions that humans are causing dangerous climate change held by the United States Academy of Sciences, over a hundred scientific organizations whose membership includes experts with expertise relevant to the science of climate change, and 97 percent of scientists who actually do peer-reviewed research on climate change?

4. When you claim that the United States need not adopt climate change policies because adverse climate change impacts have not yet been proven, are you claiming that climate change skeptics have proven that human-induced climate change will not create adverse impacts on human health and the ecological systems of others on which their life often depends and if so what is that proof?

5. When you claim that the United States should not adopt climate change policies because there is scientific uncertainty about adverse climate change impacts, are you arguing that no action of climate change should be taken until all scientific uncertainties are resolved given that waiting to resolve all scientific uncertainties before action is taken will very likely make it too late to prevent dangerous human-induced climate change harms according to the consensus view?

6. Do you deny that those who argue that they should be allowed to continue to emit greenhouse gases at levels that may be dangerous should assume the burden of proof that their actions are safe given the strength of the consensus view on climate change science?

7. Do you deny that those who are most vulnerable to climate change’s harshest potential impacts have a right to participate in a decision about whether to act to reduce the threat of climate change in the face of scientific uncertainty?

8. Given that in ratifying the United Nations Framework Convention on Climate Change (UNFCCC) the Untied States in 1992 agreed to the following under Article 3, do you believe the United States is now free to ignore this promise by refusing to take action on climate change on the basis of scientific uncertainty?

The Parties should take precautionary measures to anticipate, prevent or minimize the causes of climate change and mitigate its adverse effects. Where there are threats of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing such measures, taking into account that policies and measures to deal with climate change should be cost-effective so as to ensure global benefits at the lowest possible cost.

(UNFCCC, Art 3)

 9. If you claim that the climate change impacts predicted by the Intergovernmental Panel on Climate Change (IPCC) have not reached a level of scientific certainty that warrants action, do you agree that climate change impacts predicted by IPCC could be wrong in both directions, potentially leading to even harsher adverse impacts than those predicted?

10. Given that for over 20 years since international climate change negotiations began, the United States has refused to commit to reduce its greenhouse gas emissions based upon the justification that there is too much scientific uncertainty to warrant action, if it turns out that human-induced climate change actually greatly harms the health and ecological systems on which life depends of others, should the United States be responsible for the harms that could have been avoided if preventative action had been taken earlier?

A Video: Even Monkeys Would Get Climate Change Justice. Why Don’t Governments and the Press?

Many of the positions taken by some governments and individuals on climate change are so obviously unjust and unfair, that monkeys would get the injustice this video argues. Monkeys are believed to be capable of responding to obvious unfairness as this video demonstrates when one monkey is given a cucumber (which monkeys don’t like that much) and another is give a grape (which some monkeys love). The monkey who gets the cucumber throws it back at the trainer when the monkey sees the other monkey getting a beloved grape.

The more serious point of this video is that those who desire to see that ethics and justice become more influential in climate change policy formation need to help others spot the injustice of actual positions being taken by governments and others on climate change policy issues rather than focus on perfect justice. Many positions of governments on climate change fail to pass minimum ethical scrutiny yet ethics and justice issues are largely being ignored in discussions of climate change policies at least in the United States. Although there is a growing literature on the ethical dimensions of climate change, most of this literature is focused on theoretical ethical questions rather than on the injustice of positions actually being taken about climate policies.

A new book, Navigating the Perfect Moral Storm, Climate Change Ethics, explains these matters in more detail and makes recommendations about how to give ethical consideration in climate change policy formation.

The purpose of this video is to encourage the press, NGOs, and concerned citizens around the world to turn up the volume on the ethical dimensions of climate change. Despite a thirty-five year debate on climate change, for the most part, governments, NGOs, organizations, and individuals are ignoring the ethical dimensions of climate change even though an increased focus on ethics and justice is needed to move the world to a global solution to this immense threat.  The video argues that ethics is the crucial missing element in the climate change debate and if an ethical framing of most climate change policy issues were taken seriously it would transform how the public debate on climate change takes place.

Will Hurricane Sandy Remedy The US Media’s Grave Failures To Adequately Cover Climate Change?

 

 

(CBS News, 2012)

 

 

Hurricane Sandy is clearly responsible for a renewed interest in the American press about climate change.  For a  good sample of how the US media has, at least for the short-term, woken up to climate change see an excellent summary of  press coverage of links between Sandy and climate change on the website Residence on Earth at www.anothergreenblogg.wordpress.com,

Will this new interest in human-induced global warming lead to a cure of the grave US media failures to  communicate adequately to the American people the urgency and magnitude of the threat to the world entailed by climate change?

Some of the press coverage of climate change after Sandy is likely to improve. For instance, there is some hope after Sandy that the press will no longer ignore the monumental scale of the potential damages  to the United States as our planet continues to heat up.  As the Los Angeles Times recently reported:

Perhaps the most important message from Sandy is that it underscores the enormous price of underestimating the threat of climate change. Damage increases exponentially even if preparations are only slightly wrong. (Linden 2012)

And so Sandy may convince Americans that the threat of climate change is real and the damages of inaction are immense. However, there is very little evidence in the most recent reporting in the US press on Sandy and climate change that other grave failures of the American media to cover climate change will be remedied.  In fact US media reporting on climate change in the last few weeks has focused primarily on whether Sandy demonstrates that the threat of climate change is real.  Still missing  from mainstream media coverage of climate change are the 5 features on climate change that US citizens must understand to fully comprehend the urgent need of United States government to enact strong policies to reduce US emissions of greenhouse gases. As we have  explained in the last six articles on EthicsandClimate.org missing from US media coverage of climate change are:

  • the nature of the strong scientific consensus on climate change,
  •  a clear understanding of the magnitude and the urgency of total greenhouse gas emissions reductions necessary to prevent catastrophic warming,
  • a recognition a of the practical significance for policy that follows from an understanding that climate change is a civilization challenging ethical issue, 
  • acknowledgments  that the United States has been a significant barrier to finding a global solution to climate change for over 2 decades, and
  • an understanding of the nature of the well-organized, well-financed disinformation campaign that has been operating in the United States for over 20 years and that has been funded largely by fossil fuel interests and free market fundamentalist foundations.

EthicsandClimate.org has developed a video that summarizes these failures: Five Grave Communication Failures of the US Media on Climate Change that can be found at: http://blogs.law.widener.edu/climate/2012/10/15/five-grave-communications-failures-of-the-us-media-on-climate-change/

In previous entries, Ethicsandclimate.org examined the failure of the US media to communicate about: (a) the nature of the strong scientific consensus about human-induced climate change, (b) the magnitude of greenhouse gas emissions reductions necessary to prevent catastrophic climate change,(c) the practical significance for policy that follows from understanding climate change as essentially an ethical problem, (e) the consistent barrier that the United States has been to finding a global solution to climate change in international climate negotiations, and (f)  the failure of the US media to help educate US citizens about the well-financed, well-organized climate change disinformation campaign.

Unless these other features of climate change are understood, there is a huge risk that Americans will not support strong climate change policy measures of the scale needed in the United States.

The US Media’s Grave Failure To Communicate The Significance of Understanding Climate Change as A Civilization Challenging Ethical Issue.

I. Introduction

This is the fourth entry in a series that is examining grave communications failures of the US media in regard to climate change. In this series we examine how the American media has utterly failed to communicate to US citizens about five essential aspects of climate change that need to be understood to know why climate change is a civilization challenging problem that requires dramatic, aggressive, and urgent policy action to avoid harsh impacts to hundreds of millions of people around the world.  EthicsandClimate.org has recently developed a video that summarizes these failures: Five Grave Communication Failures of US Media on Climate Change at: http://blogs.law.widener.edu/climate/2012/10/15/five-grave-communications-failures-of-the-us-media-on-climate-change/

This is the third paper that examines in more detail the issues briefly examined in the video. In the last two entries we examined the failure of the US media to communicate about: (1) the strong scientific position on climate change, and (2) the magnitude of greenhouse gas emissions reduction necessary to avoid catastrophic climate impacts. In this post we look at the failure of the US press to communicate about the significance for policy of seeing climate change as an ethical issue.

Subsequent posts will examine the following additional communication failures of the US media:

  •  The consistent barrier that the United States has been in developing a global solution on climate change for over 20 years.
  •  The nature of the climate change disinformation campaign in the United States.

II. Significance of Understanding Climate Change as A Civilization Challenging Ethical Issue.

There has been almost no coverage in the American press about the ethical duties of governments, organizations, businesses, and individuals to reduce the threat of climate change other than occasional general assertions by some activists or members of a religious groups referring to climate change as a moral issue. When substantive issues about climate change policies have been debated in the United States, there has not been a whimper in the US press about the ethical dimensions of climate change in general or the ethical implications for specific issues under consideration.

 The evidence for this widespread failure to understand the practical significance of seeing climate change as a moral issue includes the almost universal failure of the press or advocates of climate change policies to ask businesses, organizations, or individuals who oppose national climate change policies on the grounds of economic cost alone, whether they deny that, in addition to economic interests, nations must comply with their obligations, duties, and responsibilities to prevent harm to millions of poor, vulnerable people around the world. In the United States and other high-emitting nations there is hardly a peep in the US media about the practical consequences of seeing climate change as a world-challenging ethical problem.

If climate change is understood as essentially an ethical problem, several practical consequences for policy formation follow. Yet it is clear that there has been widespread failure of those engaged in climate change policy controversies to understand the enormous practical significance for policy formation of the acknowledgement that climate change is a moral issue.

Given the growing urgency of the need to rapidly reduce global greenhouse gas emissions and the hard-to-imagine magnitude of global emissions reductions needed to stabilize atmospheric concentrations at reasonably safe levels, the failure of many engaged in climate change controversies to see the practical significance of understanding climate change as an ethical problem must be seen as a huge human tragedy.

Without doubt, there are several reasons why climate change must be understood essentially as a civilization challenging ethical problem. yet very few people appear to understand what practical difference for policy formation follows if climate change is understood as an ethical problem.

Why is climate change fundamentally an ethical problem?

First, climate change creates duties, responsibilities, and obligations because those most responsible for causing this problem are the richer developed countries or rich people in developed and developing countries, yet those who are most vulnerable to the problem’s harshest impacts are some of the world’s poorest people. That is, climate change is an ethical problem because its biggest victims are people who have done little to cause the immense threat to them.

Second, climate-change impacts are potentially catastrophic for many of the poorest people around the world. Climate change harms include deaths from disease, droughts, floods, heat, and intense storms, damages to homes and villages from rising oceans, adverse impacts on agriculture, diminishing natural resources, the inability to rely upon traditional sources of food, and the destruction of water supplies. In fact, climate change threatens the very existence of some small island nations. Clearly these impacts are potentially catastrophic. Yet there is growing evidence that greenhouse gas levels and resulting warming may be approaching thresholds that could lead to losing control over rising emissions.

Third, climate change must be understood to be an ethical problem because of its global scope. If other problems are created at the local, regional, or national scale, citizens can petition their governments to protect them from serious harms. But at the global level, no government exists whose jurisdiction matches the scale of the problem. And so, although national, regional, and local governments have the ability and responsibility to protect citizens within their borders, they have no responsibility to foreigners in the absence of international law. For this reason, ethical appeals are necessary to motivate governments to take steps to prevent their citizens from seriously harming foreigners.

Although a few people  have acknowledged that climate change must be understood as an ethical problem, the practical significance for policy formation that follows from this recognition appears to be not widely understood. The following are ten practical consequences, among many others, for policy formation that flow from the acknowledgement that climate change is an ethical problem. Although there are some climate change ethical issues about which reasonable ethical principles would reach different conclusions about what ethics requires, the following are conclusions about which there is a strong overlapping consensus among ethical theories. The ethical basis for these claims have been more rigorously worked out in prior articles on Ethicsandclimatge.org and are not repeated here.

If climate change is an ethical problem, then:

1. Nations or sub-national governments may not look to their domestic economic interests alone to justify their response to climate change because they must also comply with their duties, responsibilities, and obligations to others to prevent climate-change caused harms.

2. All nations, sub-national governments, businesses, organizations, and individuals must reduce their greenhouse gas emissions to their fair share of safe global emissions. Although different theories of distributive justice would reach different conclusions about what “fairness” requires quantitatively, most of the positions taken by opponents of climate change policies fail to pass minimum ethical scrutiny given the huge differences in emissions levels between high and low emitting nations and individuals and the enormity of global emissions reductions needed to prevent catastrophic climate change. Any test of  “fairness” must look to principles of distributive or retributive justice and must be supported by moral reasoning.

3. No nation may refuse to reduce its greenhouse gas emissions to its fair share of safe global emissions on the basis that some other nations are not reducing their emissions to their fair share of safe global emissions. All nations must reduce their greenhouse gas emissions to their fair share of safe global emissions without regard to what other nations do.

4. No national policy on climate change is ethically acceptable unless it, in combination with fair levels of greenhouse gas emissions from other countries, leads to stabilizing greenhouse gas atmospheric concentrations at levels that prevent harm to those around the world who are most vulnerable to climate change. This is so because any national position on climate change is implicitly a position on adequate global atmospheric greenhouse gas concentration stabilization level and all nations have a duty to prevent atmospheric greenhouse concentrations from exceeding levels that are harmful to others.

5. Because it has been scientifically well established that there is a great risk of catastrophic harm from human-induced change (even though it is acknowledged that there are remaining uncertainties about timing and magnitude of climate change impacts), no high-emitting nation, sub-national government, organization, business, or individual of greenhouse gases may use some remaining scientific uncertainty about climate change impacts as an excuse for not reducing its emissions to its fair share of safe global greenhouse gas emission on the basis of scientific uncertainty. The duty to prevent great harm to others begins once a person is on notice that they are potentially causing great harm, not when the harm is absolutely proven.

6. Those nations, sub-national governments, organizations, businesses, and individuals that are emitting greenhouse gases above their fair share of safe global emissions have obligations, duties, and responsibilities for the costs of adaptation or damages to those who are harmed or will be harmed by climate change.

7. Given the magnitude of potential harms from climate change, those who make skeptical arguments against the mainstream scientific view on climate change have a duty to submit skeptical arguments to peer-review, acknowledge what is not in dispute about climate change science and not only focus on what is unknown, refrain from making specious claims about the  mainstream science of climate change such as the entire scientific basis for climate change that has been completely debunked, and assume the burden of proof to show that emissions of greenhouse gases are benign.

8. Those nations or entities that have historically far exceeded their fair share of safe global emissions have some responsibility for their historic emissions. Although the date at which responsibility for historic emissions is triggered is a matter about which different ethical theories may disagree, at the very least nations have responsibility for their historical emissions on the date that they were on notice that excess greenhouse gas emissions were dangerous for others, not on the date that danger was proven.

9. In determining any nation’s fair share of safe global emissions, the nation must either assume that all humans have an equal right to use the atmosphere as a sink for greenhouse gases, or identify another allocation formula based upon morally relevant criteria. All nations have an ethical duty to explain why any deviation from per capita greenhouse gas emissions is ethically justified.

10. Some economic tools frequently used to evaluate public policy on climate change such as cost-benefit analysis that doesn’t acknowledge responsibility for allocating the burdens for reducing the threat of climate change on the basis of distributive justice are ethically problematic.

Given that climate change is obviously an ethical problem, and that if climate change is understood as an ethical problem it has profound significance for climate policy, the utter failure of the US media to cover climate change as an ethical problem is an enormous practical error and tragedy.

The US Media’s Grave Communication Failure On The Magnitude Of GHG Emissions Reductions Necessary To Prevent Dangerous Climate Change

 I. Introduction

This is the third entry in a series that is examining grave communications failures of the US media in regard to climate change. In this series we examine how the American media has utterly failed to communicate to US citizens about five essential aspects of climate change that need to be understood to know why climate change is a civilization challenging problem that requires dramatic, aggressive, and urgent policy action to avoid harsh impacts to hundreds of millions of people around the world.  EthicsandClimate.org has recently developed a video that summarizes these failures: Five Grave Communication Failures of US Media on Climate Change at: http://blogs.law.widener.edu/climate/2012/10/15/five-grave-communications-failures-of-the-us-media-on-climate-change/

This is the second paper that examines in more detail the issues briefly examined in the video. In the last entry we examined the failure of the US media to communicate about the nature of the strong scientific consensus about human-induced climate change. In this post we look at the failure of the US press to communicate about the enormous magnitude of greenhouse gas emissions reductions necessary to prevent harsh climate change impacts.

Subsequent posts will examine the following additional communication failures of the US media:

  •  The consistent barrier that the United States has been in developing a global solution on climate change for over 20 years.
  •  The fact that climate change must be understood as a civilization challenging ethical problem, an understanding that is of profound significance for climate change policy formation.
  •  The nature of the climate change disinformation campaign in the United States.

II. Communication Failures On The Magnitude Of The GHG Emissions Reductions Necessary To Prevent Dangerous Climate Change

 Most Americans are completely unaware of the magnitude of global greenhouse gas emissions reductions necessary to prevent dangerous climate change. If US citizens don’t understand the size and scope of the problem, they will almost certainly refuse to support legislation and policies necessary to put the United States on an emissions reduction pathway that represents the US fair share of safe global emissionsBecause, as we discussed in the last entry, the scientific consensus is so strong that the world is headed to harsh and dangerous impacts, the US media’s failure to communicate clearly about the magnitude of the problem facing the world is a serious, grave, and tragic lapse.

No US national climate change strategy makes any sense unless it is understood to implicitly be a position on the US fair share of a global greenhouse gas emissions reductions pathway capable of preventing dangerous climate change. Yet when US federal climate change legislation was under consideration between 2009 and 2010, there was almost no public discussion about whether proposed US climate change legislation would reduce US greenhouse gas emissions to levels that represent the US fair share of safe global emissions.

To understand the urgency for civilization challenging emissions reductions it is necessary to understand: (a) what temperature increases will likely trigger harsh climate change impacts,  (b) what atmospheric concentrations of greenhouse gases will cause specific temperature increases that are of concern, and (c) what quantities of greenhouse gas emissions will exceed atmospheric greenhouse target concentrations. Only then can one understand the amount of global greenhouse gas emissions reductions from business as usual that are necessary to avoid dangerous climate change.

A. Dangerous Temperature Increases

The international community agreed at a meeting of the conference of the parties under the United Nations Framework Convention on Climate Change in Copenhagen in 2009 that the world must work together to limit warming to an additional 2oC to avoid rapid non-linear impacts from climate change. The 2oC warming limit was agreed to because there is widespread agreement among the vast majority of mainstream scientists that warming of more than 2oC significantly increases the probability of harsh climate impacts.

However, catastrophic harms, at least for some parts of the world, could be triggered by additional warming of less than 2oC because there is uncertainty about how the Earth will respond to different increases in temperatures. (Athanasiou and Bear 2002) The 2oC upper temperature limit is quite controversial scientifically because, as we shall see, some scientists believe that lower amounts of additional warming could set into motion rapid climate changes that could greatly harm people around the world and increases of as little as 1oC will likely greatly harm some people in some regions.

A report, “Assessment of Knowledge on Impacts of Climate Change,” prepared by the Potsdam Institute to examine the meaning of “dangerous” climate change under the UNFCCC supported the 2°C danger limit after a rigorous analysis of climate change impacts at various temperatures concluding:

Above 2°C the risks increase very substantially involving potentially large extinctions or even ecosystem collapses, major increases in hunger and water shortage risks as well as socio-economic damages, particularly in developing countries. (Hare 2003: 89)

Yet, even this report identified very serious global and regional impacts below 2°C. In fact, this report concluded that temperature increases below 1°C threaten highly vulnerable ecosystems and between 1°C and 2 °C increase the risks of damage for all ecosystems and particularly for some regional ecosystems. (Hare 2003: 89)

There is substantial scientific evidence that even a 1.5°C temperature limit would not be sufficient to protect those most vulnerable to climate change. For instance, a recent paper by Jim Hansen and seven other authors concluded that additional warming should be limited to 1°C warming to prevent serious harms. (Hansen et al 2008) To do this, existing atmospheric concentrations of CO2 must not only not be allowed to rise the small amount to 450 ppm CO2 from current levels of 394 ppm CO2 but must be reduced below existing levels to 350 ppm CO2. (Hansen et al. 2008) According to this paper, the world has likely already shot past the level of atmospheric greenhouse gas concentrations that will lead to dangerous climate change for many. According to Hansen and his collaborators, the world has already used up all of the assimilative capacity of the atmosphere and biosphere that has been available to buffer against dangerous climate change. As a result, this paper asserts that to prevent dangerous climate change the world must not only reduce its emissions but reduce existing greenhouse gas CO2 atmospheric concentrations from the current 394 ppm to 350 ppm CO2 to avoid dangerous climate change.

And so, although the international community agreed in Copenhagen to limit future warming to 2°C, this could prove to be a limit that is too high to protect millions around the world. As one observer recently noted:

We feel compelled to note that even a “moderate” warming of 2°C stands a strong chance of provoking drought and storm responses that could challenge civilized society, leading potentially to the conflict and suffering that go with failed states and mass migrations. Global warming of 2°C would leave the Earth warmer than it has been in millions of years, a disruption of climate conditions that have been stable for longer than the history of human agriculture. Given the drought that already afflicts Australia, the crumbling of the sea ice in the Arctic, and the increasing storm damage after only 0.8 °C of warming so far, calling 2°C a danger limit seems to us pretty cavalier.

(Real Climate 2009)

In thinking about an upper temperature limit, many scientists are concerned with avoiding runaway climate change. That is, they fear that global temperatures will exceed a tipping point that will trigger a release of stored carbon from the biosphere, an event that would cause further rapid climate change. Runaway climate change would mean that governments would lose the ability to control future climate change that they would otherwise have through reducing greenhouse gas emissions from fossil fuel combustion and deforestation. That is, runaway climate change means that human action would be unable to stop significant temperature increase without massive geo-engineering. (Washington and Cook 2011: 30-31) This is so because, among other things, there are vast amounts of methane stored in permafrost, methane hydrates on the ocean floor, and carbon in the forests that could be released as the world warms. If the world warms too much, increased temperatures could cause huge amounts of carbon to be released that would overwhelm the quantities of carbon being released through fossil fuel combustion and deforestation. This is known to be a possibility, because such releases of stored carbon have happened in Earth’s history and caused rapid non-linear Earth temperature changes.

And so, the magnitude of greenhouse gas reductions needed to prevent dangerous climate change is understood to be the reductions from business-as-usual that will allow atmospheric concentrations of greenhouse gases to be stabilized at levels that will limit warming to between 1 to 2°C with prudence calling for a 1°C limit. We now turn to what atmospheric greenhouse gas atmospheric concentrations levels are understood to prevent warming above these amounts.

B. Atmospheric Greenhouse Gas Stabilization Goal

The amount of warming that will be experienced from different greenhouse gas atmospheric concentrations is usually referred to as the issue of “climate sensitivity.” Climate sensitivity is somewhat uncertain as there are remaining scientific uncertainties about the magnitude of the positive and negative feedbacks in the climate system.

Climate sensitivity is usually defined to mean the amount of warming that the Earth will experience if atmospheric concentrations of COreach 560 ppm of COequivalent, where COequivalent is the metric which translates other greenhouse gases into an equivalent level of CO2 . The IPCC in its Fourth Assessment Report (AR4) concluded that climate sensitivity is likely to be in the range 2 to 4.5 °C with a best estimate of about 3°C, and is very unlikely to be less than 1.5 °C. (IPCC 2007) The IPCC also noted that climate sensitivity values substantially higher than 4.5 °C cannot be excluded. And so the temperature change that the consensus view believes is likely if all of the greenhouse gases rise to 560 ppm carbon equivalent is somewhere between 2 °C and 4.5 °C with even higher temperatures possible. The current concentration of CO2 is 394 ppm. (CO2  Now 2012)

To operationalize an upper temperature limit, the international community must set an atmospheric greenhouse gas concentration stabilization limit. Since there is scientific uncertainty about how much warming will be experienced by different atmospheric greenhouse gas concentration levels, there is significant scientific controversy about what the greenhouse gas atmospheric stabilization target should be to achieve any warming limit.

Making the calculation of emissions reductions needed at any one time is complicated by the fact that how rapidly greenhouse gas emissions must be reduced is a problem that depends upon when global emissions reductions begin. The longer the international community waits to reduce greenhouse gas emissions, the steeper the necessary emissions reductions pathway becomes. It is relatively easy to calculate the amount of additional tons of emissions that can be allowed to stabilize atmospheric concentrations at a certain level such as 450 ppm CO2 but this number will depend upon when emissions reductions begin. At any time it is therefore possible to create a budget that identifies the total tons of emissions that can be allowed before a specific atmosphere concentration is exceeded but the longer the international community waits to begin to reduce emissions, the steeper the reductions must be.

The magnitude of the challenge entailed by the need to set a greenhouse gas atmospheric concentration target becomes evident after looking at the probability of exceeding 2°C if CO2 equivalent targets are set at specific levels such as 450 or 550 ppm. In the following chart the colored lines represent emissions reduction pathways that would stabilize atmospheric concentrations of carbon dioxide equivalents at various levels. The yellow line is a pathway that would stabilize at 550 ppm. The red line is a reduction pathway that could stabilize carbon dioxide equivalent at 450 ppm. The numbers on the boxes on these two lines specify the probability of exceeding 2°C if atmospheric concentration levels are stabilized at these levels.

From this chart we therefore see that if atmospheric carbon dioxide is stabilized at 550 ppm there is between a 75% and 99% chance that the world will experience temperatures in excess of 2°C. Looking at the red line we see that even at a stabilization level of 450 ppm there is between a 45% and 86% chance that the world experience increases in temperature greater than 2°C. Because CO2 levels are already approaching 395 ppm and other greenhouse gases make current carbon dioxide equivalent levels in the vicinity of 430 ppm it becomes evident that the world is running out of time to stabilize atmospheric carbon dioxide levels in the atmospheric concentrations that would limit warming to 2°C. Because as we have seen it is possible that temperature increases as small as 1°C will create harsh impacts for some people in some parts of the world it becomes apparent that the need to reduce greenhouse gases aggressively, and dramatically, and urgently.

C. Percentage Reductions From Business As Usual Required To Stabilize Atmospheric Concentrations Of Greenhouse Gases

The startling magnitude of the challenge to the world from climate change becomes apparent upon reflection that the world is currently increasing greenhouse gas emissions  during the last decade of an average annual increase of 2.7%. (PBL 2012) Yet to stabilize carbon dioxide concentrations at about 450 ppm by 2050, global emissions will have to decline by about 60% from current levels. (Hossol 2011).  Because developing countries need to expand economic activity to escape grinding poverty according to one US White House paper, industrial countries greenhouse gas emissions would have to decline by about 80% by 2050. (Hossol 2011)

Given that greenhouse emissions are increasing year to year and that the entire world will need to reduce emissions by as much as 60% by 2050 to give any hope of remaining below 2°C, the challenge to the world is staggering. One observer sums up the situation as following:

The growth of emissions is making the task ahead more and more difficult. The longer we wait to start shrinking emissions, the faster we’ll have to shrink them to stay under budget. Here’s a visualization of what that means — some sample reduction curves with varying peak years (the four different lines are based on the four main IPCC scenarios):

(citing Anderson, K.  2011)

As you can see, if we delay the global emissions peak until 2025, we pretty much have to drop off a cliff afterwards to avoid 2 degrees C. Short of a meteor strike that shuts down industrial civilization, that’s unlikely.

This, then, is the brutal logic of climate change: With immediate, concerted action at global scale, we have a slim chance to halt climate change at the extremely dangerous level of 2°C. If we delay even a decade — waiting for better technology or a more amenable political situation or whatever — we will have no chance.

(Roberts 2011)

Although the challenge of achieving sufficient global greenhouse gas emissions to prevent 2°C is extraordinarily daunting, as we have explained above a 2°C warming limit may not prevent catastrophic harm because temperature increases more than 1°C may cause great harm.

International climate negotiations have sought to find a global solution to climate change since they began in 1990 and have struggled since then to reach a global deal among most countries to prevent dangerous climate change. Because global emissions continue to rise rather than decrease after 20 years since climate change negotiations began, the international community has lost several decades in finding a way to prevent dangerous climate change. And so, the human race may be running out of time to prevent dangerous climate change. Yet most Americans are unaware of the seriousness and urgency of the staggering problem we are facing. The US media has utterly failed to sound the alarm about the magnitude of the threat of climate change.

Five Grave Communications Failures of the US Media On Climate Change-The Failure To Communicate The Strength of The Scientific Consensus

I. Introduction

The US media has utterly failed to communicate to the American people about five essential aspects of climate change that they need to understand to know why climate change is a civilization challenging problem that requires dramatic, aggressive, and urgent policy action to avoid harsh impacts to hundreds of millions of people around the world.  EthicsandClimate.org has recently developed a video on these failures entitled: Five Grave Communication  Failures of US Media On Climate Change 

We now provide a more detailed written description of these failures in this and subsequent posts. In this post we look at the first of these communications failures, namely the failure  to communicate to US citizens the strength and nature of the current scientific consensus position on climate change.

Subsequent posts will examine the following additional communication failures of the US media:

  • The magnitude of greenhouse gas emissions reductions that are necessary to prevent dangerous climate change.
  • The consistent barrier that the United States has been in finding a global solution on climate change for over 20 years.
  • The fact that climate change must be understood as a civilization challenging ethical problem, an understanding that is of profound significance for climate change policy formation.
  • The nature of the climate change disinformation campaign in the United States.

II. The Strength And Nature Of The Current Scientific Consensus Position On Climate Change.

Most US citizens are aware that there has been an ongoing debate about the science of climate change, yet most American are completely unaware of the strength of the “consensus” position on climate change.

The consensus position is understood to be that which has been articulated by the Intergovernmental Panel on Climate Change (IPCC). The IPCC was established by the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP) in 1988 to assess for governments the scientific, technical and socio-economic information relevant for the understanding of climate change, and to identify its potential impacts and options for adaptation and mitigation. (IPCC, 2010) The IPCC does not do original research but synthesizes and summarizes the extant peer-reviewed climate change science to make recommendations for governments and policy makers. (IPCC, 2010a) The consensus position is not the consensus on all scientific issues entailed by climate change. Yet, the consensus position has the following elements:

  • The planet is warming
  • The observable warming is very likely mostly caused by human activities
  • Under business as unusual human-induced warming will likely range from 2 to 5 degrees C (although it could be greater). This warming will harm some people more than others from rising seas, increased droughts and floods, increased storms, increased vector-borne disease, deaths from heat waves, reducing food productivity, and diminished availability to water.
  • To stabilize GHG in the atmosphere will require huge reductions from business as usual.

There are several strong reasons why the “consensus” view is  entitled to respect including the following:

One, recent reports have concluded that the vast majority of scientists actually doing research in the field support the consensus scientific view.

For example, a 2009 study–published in the Proceedings of the National Academy of Sciences of the United States–polled 1,372 climate researchers and resulted in the following two conclusions.

(i) 97-98% of the climate researchers most actively publishing in the field support the tenets of ACC (Anthropogenic Climate Change) outlined by the Intergovernmental Panel on Climate Change, and


(ii) The relative climate expertise and scientific prominence of the researchers unconvinced of ACC are substantially below that of the convinced researchers.


(Anderegga et. al 2010)

Another poll performed in 2009 of 3,146 of the known 10,257 Earth scientists concluded that 76 out of 79 climatologists who “listed climate science as their area of expertise and who also have published more than 50% of their recent peer-reviewed papers on the subject of climate change” believe that mean global temperatures have risen compared to pre-1800s levels, and 75 out of 77 believe that human activity is a significant factor in changing mean global temperatures. (Doran and Zimmerman, 2009)

Two, in response to arguments from some climate change skeptics, many scientific organizations with expertise relevant to climate change have endorsed the consensus position that “most of the global warming in recent decades can be attributed to human activities” including the following:
• American Association for the Advancement of Science
• American Astronomical Society
• American Chemical Society
• American Geophysical Union
• American Institute of Physics
• American Meteorological Society
• American Physical Society
• Australian Coral Reef Society
• Australian Meteorological and Oceanographic Society
• Australian Bureau of Meteorology and the CSIRO
• British Antarctic Survey
• Canadian Foundation for Climate and Atmospheric Sciences
• Canadian Meteorological and Oceanographic Society
• Environmental Protection Agency
• European Federation of Geologists
• European Geosciences Union
• European Physical Society
• Federation of American Scientists
• Federation of Australian Scientific and Technological Societies
• Geological Society of America
• Geological Society of Australia
• International Union for Quaternary Research (INQUA)
• International Union of Geodesy and Geophysics
• National Center for Atmospheric Research
• National Oceanic and Atmospheric Administration
• Royal Meteorological Society
• Royal Society of the UK

(Skeptical Science, 2010)

Three, the Academies of Science from nineteen different countries all endorse the consensus view. Eleven countries have signed a joint statement endorsing the consensus position.
They are:
• Academia Brasiliera de Ciencias (Brazil)
• Royal Society of Canada
• Chinese Academy of Sciences
• Academie des Sciences (France)
• Deutsche Akademie der Naturforscher Leopoldina (Germany)
• Indian National Science Academy
• Accademia dei Lincei (Italy)
• Science Council of Japan
• Russian Academy of Sciences
• Royal Society (United Kingdom)
• National Academy of Sciences (USA)

(Skeptical Science, 2010):

Among the academies of sciences around the world that have issued reports supporting the consensus view is the United States Academy of Sciences that has issued four reports.

From this it can be seen that the consensus view articulated by the IPCC is strongly supported by: (1) the vast majority of climate change scientists that actually do research on human-induced climate change (2) the most prestigious scientific organizations comprised of scientists with relevant climate change expertise, and (3) academies of sciences around the world, the very institutions that have been created to advise governments on complex scientific issues. For this reason, the IPCC consensus position is entitled to strong respect that, at the very minimum, climate change poses a legitimate significant threat to human well-being and the natural resources on which life depends.

In fact, some critics have contended that the IPCC reports tend to underestimate climate change dangers and risks because the process that leads to the IPCC conclusions give representatives from countries that have consistently opposed the adoption of international climate regimes power to pressure the IPCC scientists to report only the lowest common denominator. (For a discussion of the limits of IPCC, see, Brown, 2008) In fact observations of actual greenhouse gas atmospheric concentrations, temperatures, and sea level rise are near or exceeding the IPCC worst-case predictions. One recent comparison of greenhouse gas concentrations, temperatures, and sea-level rise observations versus predictions concluded:

Overall, these observational data underscore the concerns about global climate change. Previous projections, as summarized by the IPCC, have not exaggerated but may in some respects even have underestimated the climate changes that have been observed. 
(Rahmstorf et al., 2007)

It is important as a mater of ethics to remember that if the consensus view is wrong, it could be wrong in two directions. That is, not only could IPCC be overstating the magnitude and timing of climate change in the future, they may be understating the harshness of climate change harms.

And so, the most prestigious scientific organizations in the world support the consensus view on climate change.  Yet. the United States media has almost always failed to communicate this fact when discussing controversies about climate change science. Although the US media has from time to time acknowledged that most climate scientists support the consensus view, they have almost always failed to describe strength of the consensus view that becomes apparent when one understands the magnitude of support for the consensus view by the most prestigious scientific organizations end researchers described above.

Given the enormity and harshness of impacts to hundreds of millions of people around the world from climate change coupled with the fact that United States has a special responsibility for the civilization challenging problem because of the comparatively large levels of the emissions coming from America, the failure of the US media to describe strength the scientific consensus on change is a grave and tragic error.
