I. Introduction

Interest in tackling climate change in the United States has increased somewhat recently in response to global CO2 atmospheric concentrations reaching 400 ppm, although there is almost no hope of new federal legislation soon.  Many claims have been made recently that increased use of natural gas is an important element in any US response to climate change. In this regard, the natural gas industry has made a considerable effort to convince citizens that natural gas from hydraulic fracking is part of the solution to climate change. As an example, the following is from a gas industry website.

Because carbon dioxide makes up such a high proportion of U.S. greenhouse gas emissions, reducing carbon dioxide emissions can play a pivotal role in combating the greenhouse effect and global warming. The combustion of natural gas emits almost 30 % less carbon dioxide than oil, and just under 45 % less carbon dioxide than coal.

One issue that has arisen with respect to natural gas and the greenhouse effect is the fact that methane, the principle component of natural gas, is itself a potent greenhouse gas. Methane has an ability to trap heat almost 21 times more effectively than carbon dioxide. According to the Energy Information Administration, although methane emissions account for only 1.1 % of total U.S. greenhouse gas emissions, they account for 8.5 % of the greenhouse gas emissions based on global warming potential. Sources of methane emissions in the U.S. include the waste management and operations industry, the agricultural industry, as well as leaks and emissions from the oil and gas industry itself. A major study performed by the Environmental Protection Agency (EPA) and the Gas Research Institute (GRI), now Gas Technology Institute, in 1997 sought to discover whether the reduction in carbon dioxide emissions from increased natural gas use would be offset by a possible increased level of methane emissions. The study concluded that the reduction in emissions from increased natural gas use strongly outweighs the detrimental effects of increased methane emissions.  More recently in 2011, researchers at the Carnegie Mellon University released “Life cycle greenhouse gas emissions of Marcellus shale gas”, a report comparing greenhouse gas emissions from the Marcellus Shale region with emissions from coal used for electricity generation.  The authors found that wells in the Marcellus region emit 20 percent to 50 percent less greenhouse gases than coal used to produce electricity.

(Naturalgas. org, 2013)

The interest in natural gas combustion as a potential solution to climate change has been gaining because US ghg emissions have fallen somewhat as natural gas from hydraulic fracturing technologies has been rapidly replacing coal in electricity sector generation.  In this regard, for instance, Reuters recently reported in regard to recent drops in US ghg emissions that:

Carbon dioxide (CO2) emissions from energy use in the first quarter of this year fell to their lowest level in the U.S. in 20 years, as demand shifted to natural gas-fired generation from coal-fired electricity due to record low gas prices, the energy department said.

 (Reuters, 2012)

The US  natural gas industry has often argued that a switch to natural gas will significantly reduce ghg emissions from the electricity sector because natural gas emits almost 50 % less COper unit of energy produced than  coal combustion.  For this reason, natural gas is often referred to as a “bridge fuel.” (See, e.g, Kirkland)

The following chart shows the amount of pollutants including CO2 from natural  gas, oil, and coal combustion.

coalandnaturalgas

As we can see from this chart, natural gas combustion as a source of electricity generation produces about 70 % of the CO2 as oil and 56 % of the CO2 compared to coal without including methane leakage amounts, a matter discussed below. Yet controversies remain about whether natural gas should be understood as a solution to climate change and if so to what extent. This article first identifies the controversies and then reviews these issues through an ethical lens.

II. The Controversies

Two controversies about the efficacy of switching from coal to natural gas combustion in the production of electricity need to be resolved before conclusions on the beneficial effects of natural gas in reducing ghg emissions can be made. These controversies are: (a) Lingering issues about methane leakage rates, and (b) The inability of current natural gas combustion technology to achieve the magnitude of ghg emissions required to prevent dangerous climate change particularly in the medium- to long-term.

A. Unresolved Methane Leakage Rates

Natural gas is mostly methane, a potent ghg. Natural gas production from hydraulic fracturing is known to leak methane. It is usually assumed that replacing coal with gas would reduce greenhouse gas emissions as long as the leakage of methane into the air from gas production does not exceed 3.6%. (Reuters, 2012)  Yet significant controversies remain about actual methane leakage rates. In this regard recently there has been a flurry of conflicting papers about methane leakage rates from natural gas production. For instance, US EPA concluded that methane leakage was 2.4% of total natural-gas production in 2009. Other recent studies have found leakage rates of 4%  and 9% from hydraulic fracturing operations in Colorado and Utah. (Tollefson, 2013)  As a result, no rational climate change action plan or ghg inventory should ignore controversies about methane leakage from hydraulic fracking operations. Until methane leakage rates are scientifically determined, any ghg inventory or projection of future emissions should identify the range of leakage rates that appear in the extant literature.  In addition to leakage rates from natural gas production facilities, methane leakage is also known to occur in natural gas transmission lines as well as from vehicles powered by natural gas and other end uses of natural gas. Therefore, actual methane leakage rates into the atmosphere from natural gas need to be based on the sum of leakage from all of these sources that include production, transmission, and end use.

Because methane leakage rate controversies are not yet resolved, any climate change action plan must be transparent about the limitations of predicting ghg emissions from natural gas consumption and fully identify all uncertainties about leakage rates.

(b) The Need To Move Aggressively To Non-Fossil Renewable Energy Even If Natural Gas Proves to Be A Short-Term Bridge Fuel

To understand why natural gas combustion in the electricity sector is not likely be an adequate solution to climate change in the  long-term, it is necessary to understand the scale of the problem facing the world. The international community agreed in climate change negotiations under the United Nations Framework Convention on Climate Change in Copenhagen in 2009 that the international community should limit warming to 2°C to prevent dangerous climate change. In fact, countries agreed to further assess whether the 2°C warming limit needs to be replaced by a more stringent 1.5°C warming limit to avoid dangerous climate change impacts. This conclusion was confirmed in climate negotiations in Cancun in 2010, in Durban in 2011, and in Doha in 2012. A 2°C warming limit was chosen because there is substantial scientific evidence that warming above 2°C could trigger rapid, non-linear climate change threatening hundreds of millions of people around the world and the ecological systems on which life depends. Even if rapid climate change is not triggered if the 2°C warming is exceeded, this amount of warming will create huge harms to some people and nations around the world. Stabilizing CO2 equivalent concentrations at 450 ppm would only result in a 50% likelihood of limiting global warming to 2°C, and that it would be necessary to achieve stabilisation below 400 ppm to give a relatively high certainty of not exceeding 2°C.  (Report of the Scientific Steering Committee of the International Symposium on the Stabilization of Greenhouse Gases)

Limiting warming to 2°C or less will require reductions in global ghg emissions below current emissions by as much as 80 percent by mid-century for the entire world and as we explained in the a recent article on “equity” at even greater reduction levels for most developed countries. (see On the Extraordinary Urgency of Nations Responding To Climate Change on the Basis of Equity.) 

And so, the challenge facing the world to limit future warming to tolerable levels is extraordinarily daunting and will likely require a level of global cooperation far beyond any other previous  human problem.

Stabilizing atmospheric concentrations at levels that will avoid dangerous climate change requires immediate action. The entire world will need to peak its ghg emissions as soon as possible followed by emissions reductions at extraordinarily ambitious rates over the next 30 years. The longer it takes for world ghg emissions to peak and the higher ghg emissions levels are when peaking is achieved, the steeper global emissions reductions need to be to prevent dangerous levels of warming. The following chart shows the emissions reduction pathways that are needed in this century to give the world any reasonable hope of limiting warming to 2°C, assuming global emissions continue to rise at current levels during the next few years.

three reductions pathways

(Anderson, 2012)

And so it is clear that the later the peaking of total global emissions, the steeper the reduction pathways that are needed.

Further scientific analysis may reveal that methane leakage rates may be small enough to provide climate change emissions reduction benefits when coal combustion of electricity production is replaced by natural gas combustion. As we have seen this is an ongoing controversy about which further scientific analysis is needed.  Still, as explained below, given the enormity of global reductions of ghg emissions that are necessary to prevent dangerous climate change, natural gas is likely only to be a short-term bridge fuel. (IEA, 2012)

This is so because according to a recent International Energy Agency (IEA) report, natural gas can play at best a limited, very temporary role “if climate objectives are to be met.” That is, greater ghg emissions reductions are needed to prevent 2°C warming than those that can be achieved by switching from coal to natural gas combustion. And so mos observers argue that the only viable response to the threat of catastrophic climate change is rapid deployment of existing carbon-free technology. (IEA, 2012) Even if natural gas combustion creates a 50 percent less CO2 per unit of energy produced, an amount which is beyond best case on ghg emission reductions,  it will not produce the greater emissions reductions necessary in the next 30 years necessary to give any hope of restricting warming to potentially catastrophic levels.  In short, natural gas combustion cant get us where we need to be just a few decades out. It might help in the short term, but we need massive investment in non-fossil technology as soon as possible.

In addition if coal combustion were to be replaced now by non-fossil fuel energy, it would help immediately much more than conversion of coal to natural gas combustion does with putting the world on an urgently needed ghg emissions reduction pathway that gives more hope of preventing catastrophic warming.

There  are also other significant benefits of moving quickly to non-fossil fuels. For instance, according to IEA report, fuel savings from investment in non-fossil fuel technologies will pay for the investments. (IEA, 2012)  Even if natural gas is a short-term bridge fuel, delay in investing in non-fossil fuel technologies may make it impossible to meet the emissions reductions targets needed to prevent dangerous climate change. For this reason, any climate action strategy must look at emissions reductions pathways beyond 2020 necessary to limit warming to 2oC and consider what amounts of non-fossil energy are needed through 2050. Because huge amounts of non-fossil energy will very likely be required to allow the United States and other developed nations reduce their  carbon foot-print to levels required to meet their fair share of safe global emissions, the more rapid the ramp up of non-fossil energy the easier it will be to reach acceptable ghg emissions levels in the years ahead.

Furthermore, the IEA report makes it clear that abundant cheap natural gas could push renewables out of the market unless there is a price on carbon or aggressive economic support for non-fossil renewable energy.  It is  also possible that cheaper natural gas prices may lead to higher rates of consumption of electricity creating higher CO2 emissions. For this reason, any reliance on natural gas combustion as a method of reducing CO emissions must provide for ramped up commitments to non-fossil fuel sources of energy at levels needed to prevent dangerous climate change. Reliance on natural gas alone will not achieve the 80%-95%  reductions required of developed nations to prevent dangerous climate change.

Barriers to much more aggressive use of non-fossil combustion appear to be a lack of political will coupled and arguments about prohibitively high costs of non-fossil energy. We will now examine these issues through an ethical lens.

III. Ethical Analysis of the Natural Gas and Climate Change Controversies

Natural gas hydraulic fracturing technologies have created issues about social and environmental impacts that are beyond the scope of this article. Here we more narrowly examine ethical questions raised by reliance on natural gas as a solution to climate change.

Depending on how the methane leakage controversy is resolved, switching from coal combustion to natural gas combustion could help lower ghg emissions from the electricity sector in the short term.  Given that the United States has strong ethical responsibilities to rapidly reduce its carbon footprint, a matter examined extensively in Ethicsandclimate.org, one might initially conclude that as a matter of ethics switching to natural gas from coal combustion is ethically justifiable as a short-term strategy. Yet, undeniably replacement of coal combustion with non-fossil energy would create a much greater reduction in the long run in the US carbon footprint than a shift to natural gas from coal combustion would alone.  As we noted above, objections to moving immediately to non-fossil energy are lack of political will and cost arguments. We  now look at these political and cost arguments through an ethical lens.

A. The United States and Other High-Emitting Nations Have A Duty to Reduce Their Carbon Footprint As Rapidly and Dramatically As Reasonably Possible

No reasonable ethical theory could justify current US projected ghg emissions, including projected reductions that are expected to come from increased substitution of coal with natural gas at least in the medium to long term. This is so for many reasons including, first, as we have explained in considerable detail in the recent article on climate change equity, US emissions far exceed global averages in per capita emissions, the US is by far the largest contributor to historical emission which have raised atmospheric concentrations of CO2 from approximately 280 ppm to 400 ppm, and the world is now running out of time to limit warming to non-dangerous levels. Because, as we have demonstrated in the recent article on “equity” and climate change, there are approximately 50 ppm of CO2 equivalent atmospheric space that remain to be allocated among all nations to give the world approximately a 50% chance of avoiding a 2oC warming and developing nations that have done little to elevate atmospheric CO2 to current levels need a significant portion of the remaining atmospheric space , high emitting developed nations need to reduce their emissions as fast as possible to levels that represent their fair share of the remaining acceptable global budget. (See On the Extraordinary Urgency of Nations Responding To Climate Change on the Basis of Equity.) For this reason, high-emitting nations have strong ethical duties to reduce their ghg emissions as fast as possible to their fair share of safe global emissions.  Without doubt, this means that the United States has an ethical duty to reduce emissions both in the short and long run faster than switching to natural gas combustion from coal sector will allow by itself.

As we have previously explained in EthicsandClimate.org there is now a scientific consensus that developed countries must limit their ghg emissions by as much as 25% to 40 % below 1990 emissions levels by 2020 and between 80% and 95% below1990 levels by 2050 to have any reasonable chance of avoiding dangerous climate change which would require atmospheric ghg concentrations to be stabilized at 450 ppm. (IPCC, 2007: 776)   (Also see, What You Need To Know to Understand the Scale of the Climate Change Problem and The Continuing US Press Failure to Report on the Urgency of this Civilization Challenging Threat) 

The actual amount of emissions reductions that are needed between now and 2020 is somewhat of a moving target depending on the level of uncertainty that society is willing to accept that a dangerous warming limit will be exceeded, the most recent increases in ghg emissions rates, and assumptions about when global ghg emissions peak before beginning rapid reduction rates.

One new study shows that we have to reduce emissions even more than scientists initially thought in order to avoid climate change’s worst impacts. A paper published in Energy Policy on February 20, 2013 by Michel den Elzen and colleagues examines new information on likely future emissions trajectories in developing countries.  (Ezden, 2013) As a result, the report finds that developed countries must reduce their emissions by 50% below 1990 levels by 2020 if we are to have a medium chance of limiting warming to 2°C, thus preventing some of climate change’s worst impacts.

As we have seen above, to stabilize atmospheric concentrations at levels that will avoid dangerous climate change the entire world will need to peak its emissions in the next few years followed by emissions reductions at hard to imagine rates over the next 30 years.

As we have also explained in EthicsandClimate. org, US reductions need to be much greater than average reduction levels required of the entire world as a matter of equity because the United States emissions are among the world’s highest in terms of per capita and historical emissions and there is precious little atmospheric space remaining for additional ghg emissions if the world is serious about avoiding dangerous climate change.  (See, What You Need To Know to Understand the Scale of the Climate Change Problem and The Continuing US Press Failure to Report on the Urgency of this Civilization Challenging Threat)

No matter what reasonable assumptions are made about carbon budgets that need to guide the world’s response to avoid dangerous climate change, as a matter of ethics, the US has a duty to reduce its ghg emissions both in the short and long run to levels much greater than switching to natural gas combustion from coal will accomplish by iteslf.

Even if switching to natural gas in the short term reduces the US carbon footprint somewhat, it is still not sufficient by itself to put the US on an emissions reduction pathway consistent with its ethical obligations without other policy interventions including putting a price on carbon or rapid ramp up of renewable energy. Given that the natural gas is likely to reduce costs of electricity production, there is also some risk that with lower costs demand for electricity will increase which will undermine both incentives for finding increases in efficiency while raising ghg emissions levels. For this reason, the United States needs to create an emissions reduction target consistent with its obligations to the world. (See,  On the Extraordinary Urgency of Nations Responding To Climate Change on the Basis of Equity.)

Although ethical reflection on benefits of short term switching to natural gas reveals the above ethical questions, long-term reliance on natural gas as a climate change solution raises greater issues of ethical concern. This is so because although switching to natural  gas combustion from coal can reduce temporarily the US carbon footprint when coupled with the right policy measures, there is no hope that natural gas combustion alone can achieve the huge emissions reductions necessary to put the United States on an emissions reduction pathway that matches the US ethical obligations to prevent dangerous climate change. The United States urgently needs to adopt policies that will ramp up its use of non-fossil energy immediately. Investment in natural gas combustion could delay investment in non-fossil energy. Moreover the amount of non-fossil energy needed to put the US on an emissions reduction pathway consistent with its ethical obligations requires the United States to begin immediately as a matter of ethics. The longer the United States waits to move more aggressively to increase the share of non-fossil energy, the more difficult, if not impossible, it will be to meet non-fossil energy needs a few decades from now. And so as a matter of ethics a strong case can be made that the United States needs immediately to adopt policies designed to aggressively increase levels of  non-fossil energy.

And so if political will is a barrier to greater use of non-fossil energy, politicians resisting greater commitment to non-fossil energy are most likely supporting positions that fail to pass minimum ethical scrutiny.

The fact that much greater US commitments to renewable energy are feasible is demonstrated by looking at achievements of other nations.  Germany, for instance, has set a goal of 100% renewable energy in its electricity sector by 2050. (The Gaurdian, 2010) Germany’s Environment Agency’s study found that switching to 100 % green electricity by 2050 would have economic advantages, especially for the vital export-oriented manufacturing industry (The Gaurdian, 2010) It would also create tens of thousands of jobs.

B. Ethical Analysis of Cost Arguments In Opposition to Non-Fossil Electricity Generation

There are many factual issues that could be contested in regard to any argument that switching to a non-fossil  fuel future is cost-prohibitive. As we have seen, for instance, Germany claimd that an aggressive move to a non-fossil future has economic benefits. (For a good discussion of economic arguments for aggressive policies in support of renewable energy see, Germany Energy Transition, Henric Boll, 2012)

Cost arguments made in opposition to aggressive policies in support of a non-fossil future many not only be challenged on a factual basis but also on an ethical basis.  There are several ethical issues raised by such cost arguments that have been extensively looked at in prior articles in EthicsandClimate.org. These ethical issues include

  •  Cost arguments are often deeply ethically problematic because they ignore duties, responsibilities, and obligations to others to reduce ghg emissions. That is, cost arguments usually appeal to matters of self-interest and ignore responsibilities to others including the tens of millions of poor people around the world that are already suffering from climate change impacts or who are much more vulnerable to much harsher climate change impacts in the future than the United States is.
  •  Cost arguments are ethically problematic if they fail to examine the costs of non-action and only consider the costs to high emitters of reducing ghg emissions. Given that most economists now believe that costs of non-action far exceed costs of reducing the threat of climate change, costs considerations that only consider costs to polluters are both deeply ethically troublesome and radically incomplete.
  • Costs arguments may not be made against climate change policies if greenhouse gas emissions lead to serious human rights violations of victims who have not consented to be put at risk.
  • Cost arguments often translate all values to economic values measured in markets and thereby transform some things that victims hold have sacred value into commodity value.
  • Cost arguments usually ignore questions of distributive justice while arguing that government policy should be based upon maximizing economic efficiency or utility.  Distributive justice issues that are frequently ignored by the use of cost arguments to oppose climate policy include the fact that costs would be imposed on those who are causing the problem yet the victims of climate change that would benefit from taking action are some of the poorest people around the world that have done little to cause the problem
  • Cost arguments usually ignore issues of procedural justice including the right of victims to consent to being put at risk to climate change impacts.
  • Cost arguments alone usually ignore well settled norms of international law including the “polluter pays” and “no harm” principles that the United States and almost all other nations have agreed to in ratifying the United Nations Framework Convention on Climate Change.

In conclusion, we have identified strong ethical arguments that support the need to ramp up non-fossil fuel combustion in the United States and other developed countries while implicitly acknowledging that there could be some short-term benefit if coal combustion is replaced by natural gas, a conclusion that only can be reached with better understanding of the methane leakage issues. Yet even if there is some short-term benefit from substituting natural gas for coal combustion, there is no ethical basis for doing this without simultaneously aggressively ramping up non-fossil fuel electricity combustion.  We note that some in the natural gas industry and their political  supporters continue to oppose policies designed to ramp up non-fossil fuel combustion at the same time claiming that natural gas is a solution to climate change. Because the failure to ramp up non-fossil fuel combustion Under the circumstances discussed in this article,  such opposition is ethically problematic.

On the Extraordinary Urgency of Nations Responding To Climate Change on the Basis of Equity.

400ppm

This  article seeks to explain in understandable terms why nations must not only aggressively respond to climate change but respond at levels required of them by equity if the world is going to have any hope of avoiding dangerous climate change. And so, this article seeks to help citizens around the world understand why their nations must create climate change policies consistent with their equitable obligations and that if their nations fail to respond on the basis of equity, there is vey little hope of an adequate global solution emerging    that has any potential of avoiding catastrophic climate change.

Once again there has been some renewed interest in responding to climate change this week in response to the announcement by the National Oceanic and Atmospheric Administration (NOAA) that carbon dioxide (CO2) atmospheric concentrations have reached 400 ppm (parts per million). This concentration of CO2 is not only higher than experienced in the last 3 million years of Earth’s history  (Kunzig, 2013), it is additional evidence that the world is rapidly running out of time to prevent dangerous climate change.  NOAA posted on its website Wednesday night, May 9, that the daily average for CO2 was 400.03 ppm. (Kunzig, 2013)   The last time the concentration of the CO2 reached this mark, horses and camels lived in the high Arctic and seas were at least 30 feet higher. (Kunzig, 2013) This sea level  rise would  inundate major cities around the world and cause harm to hundreds of millions around the world when temperatures finally responded to these elevated greenhouse gas (ghg) atmospheric concentrations.

Although this story made it to the front page of the New York Times, (see Schuetze 2013), the US press continues to fail to educate American citizens fully about the seriousness of the problem that the world is facing particularly in regard to the urgent need of nations to take immediate steps to reduce their emissions to their fair share of safe global ghg emissions.  Ethicsandclimate.org has previously examined the failure of the US press to communicate to American people the importance of the equity issue in formulating US policy. (See, The US Media’s Grave Failure To Communicate The Significance of Understanding Climate Change as A Civilization Challenging Ethical Issue.Yet, as we will explain, in light of the rapidly decreasing amount of time remaining for the world to prevent dangerous climate change, there is now more than ever a need to increase political support at the national level around the world for the adoption of policies on climate change that reflect each nation’s fair share of safe global emissions.

rich countriesWhen almost all nations around the world agreed to the 1992 United Nations Framework Convention on Climate Change (UNFCCC), they promised  to adopt policies and measures to limit warming based upon “equity” to prevent dangerous anthropogenic interference with the climate system. (UNFCCC, Art. 3) Up until very recently it was possible for nations to ignore that they had a responsibility to reduce their ghg emissions to levels based upon “equity.” And so many, if not most, nations have been entering international climate negotiations as if they need only look to their national economic interest to determine what ghg emissions reductions commitments they need to make under the UNFCCC. However, now that the world is running out of time to prevent dangerous climate change, the urgent need of nations to reduce their emissions to levels required of them on the basis of equity and basic fairness is now obvious and undeniable. This was not the case only a few years ago.  For instance, just three years ago it was possible for the United States to ignore what was required of it as a matter of basic fairness because nations were happy when the United States made any commitment to reduce its ghg emissions having refused to do so from the early 1990s through 2010. Any US commitment was viewed as a positive step. And so, when President Obama made a voluntary commitment in 2010 in Copenhagen to reduce US emissions by 17% below 2005 levels by 2020, it was widely celebrated throughout the international community even though most observers knew this commitment was far short of what justice required of the United States. Yet just two years later in Qatar, the same US commitment was almost universally condemned on justice grounds. (See: Qatar: Bumping Up Against Climate Change Limitations On Human Activities Makes Ethical and Justice Issues Unavoidable) 

The importance of each government entity’s responsibility to limit their emissions to their fair share of safe global emissions has become undeniably obvious to most observers of international climate negotiations now that it has become clear to all that there is precious little time for the global community to avoid dangerous climate change. The central importance of the need to get nations to respond to climate change on the basis of “equity” becomes very obvious once a number of scientific aspects of climate change are fully understood. However, too few people understand these scientific aspects of climate change and the press is failing to educate citizens about these issues.

To fully understand the importance of national responses on the basis of “equity” it is necessary to understand some features of climate change that make it unlike any other environmental problem facing the world. The atmosphere is like a bathtub, it has limited volume. Nations have been filling up the atmospheric bathtub since the beginning of the industrial revolution in the late 1790s. Because CO2 is long-lived in the atmosphere, the bathtub continues to fill up with CO2 even if rates of CO2 emissions slow down somewhat unless all ghg emissions are reduced to the rate at which the Earth’s natural carbon cycle can remove CO2, an amount which is less than 20% of existing emissions levels. Decreasing ghg emissions does not prevent global atmospheric concentrations from increasing unless they are cut back globally by huge amounts. And so to prevent dangerous climate change nations have to do much more than cut back on the ghg emissions levels that they are entering the atmosphere, they have to cooperate to prevent the level in the bath tub from reaching levels that will cause dangerous climate change. As we shall see, this is a level that the world is fast approaching. Furthermore because CO2 is well mixed in the atmosphere it makes no difference where on Earth the ghgs come from, the atmospheric concentrations of ghg continue to rise without regard to location of the source of emissions.

What makes the current climate change threat so ominous is that the levels of CO2 that have been building up for over 200 years are quickly approaching levels that could trigger dangerous climate change as emissions are increasing in many parts of the world.

In our experience, most Americans don’t understand the scale of the climate change facing the world. In Copenhagen in 2010 the international community agreed to set as a goal warming limit of 2°C not withstanding there are some scientific evidence to believe that the warming limit should be lower at 1.5 °C. The 2°C warming limit was chosen because there is strong scientific evidence that warming above 2°C could trigger rapid nonlinear climate change thereby threatening hundreds of millions of people around the world and the ecological systems on which they depend. Even if 2°C warming doesn’t trigger nonlinear warming, this amount of warming will cause great harm around the world to people and places that have done little to cause climate change.

The following graph describes the staggering challenge facing the world if the international community desires to limit warming to 2°C.  The graph depicts three different emissions reductions pathways where the steepness of ghg emissions reductions needed to limit 2°C depend upon when global emissions levels peak, that is in 2015, 2020, or 2025. Despite over twenty years since the international community agreed in 1992 to adopt policies and measures based upon equity to prevent dangerous climate change, global ghg emissions levels continue to rise despite a global economic turn down in 2008. Global CO2 emissions grew 3 percent in 2011 and were estimated to rise 2.6 in 2012. (Morello, 2012).  Since the international community began to negotiate a climate change solution, rather then emissions levels diminishing they have  grown to 58 percent above the 1990 emissions level in 2012 (Morello, 2012). And so, the world is facing the urgent need to reduce ghg emissions at hard to imagine rates as seen in the following graph where the different colored lines on this chart represent different assumptions about climate sensitivity. This graph shows that if the world waits to act together to prevent ghg emissions from rising until 2020 or 2025, the world will need to reduce ghg emissions at staggering reduction levels after the peak years.

three reductions pathways

 

 

 

 

(Anderson, K.. 2012)

On the basis of the magnitude of the ghg emissions reductions challenge facing the world, mainstream scientists around the world are now emphatically trying to get the world’s attention about the urgency of the need to act dramatically to prevent dangerous climate change. Yet there has been little discussion in the media about the importance of equity in national responses to this global emergency coupled with the fact that one needs to understand other aspects of the climate change problem to fully understand the importance of requiring nations to reduce their emissions based upon “equity.”

Once one identifies an atmosphere ghg concentration level that will serve as a goal for preventing dangerous warming it is a relatively straightforward calculation to identify the remaining amounts of ghg emissions that can be emitted worldwide to prevent atmospheric ghg concentrations from exceeding the maximum concentration goal. This calculation is the basis for determining an emissions budget. Because there is some uncertainty about climate sensitivity, that is how much warming the Earth will experience at different atmospheric ghg concentrations, different atmospheric ghg concentration goals create different levels of probability of limiting warming to 2°C.  The following chart identifies the quantity of ghg emissions in gigatons of CO2 equivalent that the world may emit to achieve different levels of probability that the 2° C warming limit will not be exceeded. Therefore we see from this chart that if the entire world is assumed to be allowed to emit no more than 886 gigatons (Gt) of CO2 equivalent, this budgetary limit creates between a 8% and 37%, with a best estimate of 20%, probability that temperatures will exceed the warming limit of  2°C.   At the upper end of this chart, a 1437 Gt CO2 budgetary limit creates a probability of between 29 to 70 probability, with a best estimate of 50%, that the  2°C warming limit will be exceeded.

The chart also shows that if the world emits ghgs at levels projected at 56 Gt per year, then, assuming that the world chooses to live with a budget of 886 Gt CO2 which gives the world an 80% probability that future warming will be limited to 2°C, then after12 years there will be zero emissions left in the budget.  The chart also demonstrates that even if the world chooses to run the risk of accepting a 50% probability that the 2°C warming will be exceeded then world can only emit greenhouse gases at projected levels for 22 years.
budget

As gloomy as this picture in regard to the remaining global ghg emissions budget, we have not yet explained why getting nations to commit to reduce their emissions to levels required of them by equity is so important and indispensable for thinking clearly about how the world must respond to the threat of climate change. And so, now, for the first time, we can explain the importance of “equity” in guiding international responses to climate change.

Returning to the use of a bathtub as a metaphor for the atmosphere, we note that there is already elevated levels of ghg (metaphorically water) in the bathtub that have risen to current levels from over 200 years of human activities. That is CO2 has increased in the atmosphere from 280 ppm to 400 ppm since the beginning of the industrial revolution. If we assume that atmospheric concentrations of CO2 equivalent should be limited to 450 ppm to give the world a 50% chance of keeping warming from exceeding the 2°C warming limit, atmospheric concentrations have increased already by120 ppm from pre-industrial levels and only 50 ppm of atmospheric space are  left to allocate to the entire world.  The 120 ppm increase in atmospheric CO2 concentrations that has already been put into the bathtub by human activities has overwhelmingly been caused by activities in some rich, developed countries much more than poor developing countries.  The following chart shows which countries have contributed the most elevated concentrations of CO2 in the atmosphere.
cummualative over time

(EPA, 2002)

And so some countries more than others have contributed far more than others to elevated ghg concentrations. Given that there’s only 50 ppm of atmospheric space left to allocate (assuming and atmospheric goal of 450ppm giving approximately a 50 % chance of exceeding  the 2°C) and some developing countries desperately need to use the remaining atmospheric space to escape grinding poverty, it is obviously unfair or inequitable to require all countries to reduce emissions by the same amount.

Percapita nationaFurthermore, the above chart demonstrates that some countries including the United States, Canada,  and Australia, for instance, far exceed others in per capita levels of emissions from their citizens compared to other countries such as India.

If it is determined that the entire world must reduce its emissions by 80% below 1990 levels to prevent dangerous climate change, high-emitting nations or governments around the world, including the US, Canada, and Australia, will need to reduce their emissions to even greater levels on the basis of equity and fairness. To require each nation or government to reduce emissions by the same percentage amount would freeze into place unjust emission levels for high-emitting governments and very low emissions rates for poor developing countries.  For this reason, almost all the nations of the world, including the United States in 1992 when it ratified the UNFCCC, agreed that each nation must reduce its emissions on the basis of “equity” to prevent dangerous climate change. (UNFCCC, 1992: Art 3, Para 1) If all nations need only reduce their emissions by equal percentage amounts, then a high-emitting nation like the United States that emits ghg at rate of 17.3 tons per capita would be allowed to emit at a level 10 times more per capita than a country like Vietnam that emits 1.7 tons of ghg per capita. (World Bank, 2012b) As a result, all nations have agreed that national targets must be based upon fairness or equity.

Given that the entire world has only 50 ppm of atmospheric space left to allocate to give the world a reasonable expectation of preventing dangerous climate change, the equitable and fairness dimensions of national ghg emissions reductions commitments become obvious and crucial to increasing the ambition of nations to reduce their ghg emissions. Yet most citizens seem completely unaware of the equity issues entailed by climate change and many high-emitting nations are ignoring their equitable responsibilities.

However, the ability of nations to ignore what equity requires of them will become more and more difficult as the world wakes up to the hard-to-imagine stringent carbon budget that the world must face to avoid catastrophe warming. In addition the longer nations wait to respond to climate change on the basis of equity, the more difficult it will be in the future to do so because the steepness of their emissions reductions pathways needed to comply with what equity requires increases the longer nations wait to respond appropriately.

A video: Why Politicians May Not Rely On Their Own Uninformed Opinion On Climate Change Science.

http://blogs.law.widener.edu/climate/files/2013/02/Slide4.jpgThis 11 minute video examines why politicians, unlike many ordinary citizens,  may not rely upon their own uninformed opinion on climate change science as a basis for refusing to support climate change policies. The video argues that politicians have responsibilities that ordinary citizens do not have to protect others from harms that their constituents are causing others.

Qatar Climate Change Negotiations: An Open Letter To US President Obama From the World’s Poorest Nations.

I. Introduction

Over the next few weeks EthicsandClimate.org will be focusing on the upcoming Qatar climate negotiations, the 18th Conference of the Parties (COP-18) that will be held from November 26th to December 7th. In future entries, we will discuss in detail COP-18′s progress in achieving a global solution to climate change particularly to see the extent to which this meeting makes progress on the following minimum criteria for any post-Kyoto agreement that ethics requires.  That is, we will examine whether the Qatar proceedings:

  • Obtain commitments on  greenhouse emissions reductions sufficient to assure that the international community is on a greenhouse gas emissions reduction pathway that will prevent dangerous climate change. This is sometimes referred to as the environmental sufficiency criteria.
  •  Begin to base differences among national allocations on the basis of equity and justice. This is sometimes referred to as the equity criteria.
  • Assure that those responsible for climate change provide adequate and predictable adaptation funding to enable developing countries, and in particular the most vulnerable developing countries,  to do what is necessary to avoid climate change damages in cases where it is possible to take action and to prevent damages, or be compensated for climate change damages in cases where it is impossible to take protective action. We refer to this as the just adaptation criteria.

As we have argued in the past on EthicsandClimate, the success of any global approach to climate change depends upon the extent to which those countries with the largest emissions are willing to make  significant commitments particularly in regard to the three criteria identified above although there are many other issues that will arise in the international climate negotiations that Ethicsanclimate.org  will follow. In this regard, the United States in an indispensable element in any satisfactory international climate change regime. For this reason, we begin this analysis of the Qatar COP with the following open letter from some of the world’s poorest countries to US President Obama that was published in the Guardian.

II. Open Letter to US President Obama

Dear President Obama:

As the lead negotiator for the world’s 48 Least Developed Countries (LDCs) in the United Nations climate change negotiations, I congratulate you on your re-election. I also want to express my admiration for your response to superstorm Sandy: without the preparations that you made, the impacts to those hit by the storm would have been even more devastating. As communities in the north-east work to rebuild and recover, the world has an opportunity to begin a new, reality-based conversation about climate change.

I write with a simple request: as this discussion continues in the world’s most developed countries, remember those who live in its poorest regions. Remember that as a result of climate change, this kind of fatal weather event has become commonplace for us while we lack the infrastructure and resources to adequately protect our citizens.

As researchers at Brown University’s climate and development lab have shown, climate-related disasters such as droughts, extreme temperatures, floods, and hurricanes have caused an estimated 1.3 million deaths since 1980. Two-thirds of these deaths (over 909,000) occurred in the least developed countries. We are only 12% of the world’s population, but we suffer the effects of climate-related disasters more than five times as much as the world as a whole.

Given this reality and your early commitment to leading a science-directed discussion about the changing climate, I was surprised that you only mentioned climate change in your re-election campaign a few times, and not once in your three debates with Mitt Romney. We know that 70% of US citizens now recognise the reality of human-caused climate change. As the world’s largest economy, the US has a unique opportunity and responsibility to take bold action on this issue. Indeed, the wellbeing of the citizens of your nation and mine depends on your ability to lead at this critical juncture. It is time to end the climate silence.

Later this month, representatives of the world’s nations will meet in Doha, Qatar, for the annual negotiations on the UN climate change treaty. When you were first elected president, your words gave us hope that you would become an international leader on climate change. But you have not lived up to this promise. The framework that you put in place sets the planet on course to warm dangerously, and delays action until 2020 – this will be too late. This year’s meeting in Qatar may be our last chance to put forward a new vision and plan to reverse this course. Your legacy, and the future of our children and grandchildren depend on it. We ask you to lead in two ways.

First, join with the European Union, the LDCs and the Alliance of Small Island States in taking on ambitious national commitments to reduce climate pollution. Go beyond the commitments that you made in Copenhagen in 2009. The climate is changing faster than we thought, and we must respond with increased ambition.

Second, provide adequate funding to help the LDCs and other vulnerable nations to adapt to this new climate reality. In 2010, the wealthiest countries directed about $1.5bn to help developing countries adapt to a changing climate. Over the same period, they spent over $400bn subsidising fossil fuel industries. They gave the main contributors to human-caused climate change more than 250 times the support they offered those whom it harms most.

Countries from Gambia and Haiti, to Malawi and Bangladesh need the “predictable and adequate” funding promised in Copenhagen so that they can take simple steps to protect their citizens. This means moving drinking water and irrigation wells away from coasts, where saltwater is intruding into aquifers; it includes developing drought-resistant crops and helping small farmers in fragile, semi-arid regions survive. We have to prepare roads and cities, villages and farms for floods, hurricanes and heat waves. We need to equip people with the weather prediction, early warning systems and emergency response that citizens of the developed countries take for granted.

With 20 years of international climate change negotiations behind us, there is simply no longer time or cause for wealthy countries to continue to stall in taking real action to fulfill the promises they have made. Having the wealthy nations reduce their greenhouse gas emissions steeply is fundamental, but helping the poorest of us cope with its impacts is an immediate necessity.

Mr President, remind the world that the devastation of climate change is shared by all its citizens. Remember that this reality is changeable. Make changing it your legacy.

Pa Ousman Jarju is the chair of the Least Developed Countries group at the UN climate change negotiations.

How To Make Ethical Principles More Influential In Climate Change Policy Formation: A New Book, Navigating the Perfect Moral Storm, Climate Change Ethics

Many observers of climate change policy developments around the world agree that climate change is a civilization-challenging ethical problem, yet most governments have utterly failed to enact climate change policies consistent with what ethics and justice would require of them. For instance, nations continue to approach international climate negotiations as if their economic interests alone are a legitimate guide for domestic climate change policy formation rather than their ethical responsibilities to others.

Yet climate change is obviously a civilization challenging ethical problem because:

  • High emitting nations and individuals are putting poor people around the world at greatest risk of harm, people who have done little to cause the problem.
  • The harms to the victims are not mere inconveniences but potentially catastrophic losses of life or damages to ecological systems on which life depends.
  • Most of the victims in poor countries can do little to protect themselves from harsh climate impacts including petitioning their governments to protect them; their best hope is that high emitters will see that they have duties to the victims to lower their greenhouse gas emissions.

 A new book Navigating the Perfect Moral Storm: Climate Change Ethics, by Donald A. Brown, Scholar in Residence, Sustainability Ethics and Law at Widener University School of Law has been published that examines the major ethical questions raised by human-induced global warming, looks at how these ethical issues have been mostly ignored in a thirty-five year debate about climate change, and makes recommendations for getting greater traction for ethical guidance in climate change policy formation in the years ahead.

Most  climate change ethics literature has been focused on analyzing specific ethical issues entailed by climate change. Because different ethical theories may reach different conclusions about what should be done in respect to many of these issues, much of the existing climate change ethics literature provides little practical guidance to policy-makers about what should be done in developing policy. Yet by following positions actually taken by disputants in a thirty-year climate change policy debate, Navigating the Perfect Moral Storm makes it clear that most of the arguments made in opposition to climate change policies have been clearly ethically bankrupt even in regard to issues about which different ethical theories would reach different conclusions about what should be done.  And so it is easy to spot and clearly identify injustice of the positions that governments and individuals have taken on climate change issues even for those issues about which determining what perfect justice requires may be difficult. For this reason, Navigating the Perfect Moral Storm argues climate change ethicists should be more engaged in policy formation rather than focus exclusively on theoretical ethical issues if they desire to give ethical principles more influence in climate change policy formation.

Navigating the Perfect Moral Storm also makes it clear that despite a thirty-five year policy debate about climate change in the United States, neither the US press nor disputants in the controversy have identified the obvious civilization-challenging ethical questions raised by climate change. This had been the case because arguments in support of and in opposition to climate change have mostly been framed as “value-neutral” economic and scientific controversies, a framing which hides the obvious ethical questions. For this reason, Navigating the Perfect  Moral Storm demonstrates that there is an important practical need for the public to turn up the volume on the ethical dimensions of climate change. The book ends with specific recommendations on how to do this.

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.

In Praise and Criticism of the PBS Frontline Program, Climate of Doubt

On October 23, 2012,  the PBS program Frontline aired a program called Climate of Doubt.  available on the PBS website at www.pbs.org/frontline/  This program describes the success of right-wing organizations and some corporations in both undermining the public’s understanding of the mainstream scientific view about human-induced climate change and in preventing legislative action to reduce US greenhouse gas emissions. Climate of Doubt explains that the disinformation campaign has succeeded despite the fact that the vast majority of climate scientists that actually engage in climate change scientific research strongly support the consensus scientific view that humans are causing dangerous warming.

In a very introductory manner, the Frontline program explains how the climate change disinformation campaign has managed to weaken support for doing something about climate change and for this reason the program is a welcome addition to the otherwise largely non-existent US media coverage of who is behind the climate change disinformation campaign.

Although the Frontline program should be welcomed for bringing much needed attention to this tragic manipulation of a democracy,  at the same time the program can be criticized for missing important elements of the story necessary to get a full understanding  of the outrageousness,  if not criminality, of the climate change disinformation campaign.

Missing from the Frontline description of the disinformation campaign are:

(a) A stronger sense of the strength of the consensus view, (every academy of science in the world supports the consensus view, over a hundred scientific organizations whose members have relevant scientific expertise support the consensus view, much of the science that should have been the basis for US action on climate change was settled 150 years ago, and there are clear qualitative differences between peer-reviewed science and the manufactured, non-peer reviewed science usually relied upon by the disinformation campaign),

(b) A sense of the urgency for the need to make greenhouse gas emissions reductions as soon as possible to avoid dangerous climate change.

(c) The civilization challenging magnitude of the reductions that will be necessary to prevent dangerous climate change,

(d) The tactics of the disinformation campaign which cannot be understood as responsible skepticism, such as: (1)  making claims that not only have not been peer-reviewed but are at odds with well-settled  science, (2) cherry picking the science, (3) treating one study as undermining the entire body of climate science even though the issue in contention is not consequential in regard to the major mainstream scientific conclusions, (4) cyber-bullying scientists and journalists that publish statements that climate change is a significant threat, (5) making completely false claims that are either lies or reckless disregard for the truth such as the claim that the  entire scientific basis for action is a hoax when every academy of science supports the consensus view, and (6) the use of front groups and Astroturf groups that hide the real parties in interest behind the disinformation campaign, namely fossil fuel companies and free-market fundamentalist foundations.

(d) The fact that high-emitting nations and individuals are putting hundreds of millions of world’s poorest people at risk who have done nothing to cause the problem,

(e) The fact that the United States has been a major barrier to a global solution in climate negotiations for over two decades due to the disinformation campaign,

(f) The fact that even the Obama administration is unwilling to make commitments for emissions reductions consistent with any reasonable interpretation of the US fair share of safe global emissions,

(g) The fact that climate change must be understood as a moral and ethical issue, an understanding that undermines the purely US self-interested economic arguments made by those who oppose action on climate change,

(h) The fact that it already too late to prevent climate-change  caused  grave suffering for some people in some parts of the world and that the world has lost over twenty years during which action could have been taken to reduce the now enormous threat,

(i) The fact that hundreds of millions of people around the world who are most vulnerable to climate change’s worst threats have never consented to be put at risk while the United States waits for absolute certainty. and

(j) The fact that each year the United States has waited  to take action, the problem has become worse.

In summary, the Frontline program, although a welcome overdue US media analysis of the climate change disinformation campaign, fails to adequately explain why the disinformation campaign should be considered as some new kind of crime against humanity. The Frontline program give far to much attention to some of the climate deniers while failing to communicate adequately the strength of the consensus position.

Given what is at stake from climate change, ethics requires that those who want to discuss the uncertainties of climate change science must proceed with extreme care including limiting their claims to peer-reviewed science and not overstating the significance of individual studies.   Skepticism in science is the oxygen of science and therefor is a good thing, but many of the tactics of the disinformation campaign are clearly not responsible skepticism.  They are often deeply deceitful, ethically abhorrent disinformation.

Ethicsandclimate.org has  looked at the disinformation campaign in considerable more detail than the issues covered in the Frontline program in a four part series:

1. Ethical Analysis of the Climate Change Disinformation Campaign: Introduction to A Series Series.

2.Ethical Analysis of Disinformation Campaign’s Tactics: (1) Reckless Disregard for the Truth, (2) Focusing On Unknowns While Ignoring Knowns, (3) Specious Claims of “Bad” Science, and (4) Front Groups.

3.Ethical Analysis of Disinformation Campaign’s Tactics: (1) Think Tanks, (2) PR Campaigns, (3) Astroturf Groups, and (4) Cyber-Bullying Attacks.

4. Irresponsible Skepticism: Lessons Learned From the Climate Disinformation Campaign

Ethicsandclimate has also produced a video on why the climate change disinformation campaign is so ethically abhorrent. See. Why the Climate Change Is So Ethically Abhorrent.

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.

Five Grave Communications Failures of The US Media On Climate Change

This video examines 5 grave tragic communications failures of the US media on climate change.

These include the failure to communicate;

  1. The strength of the scientific consensus
  2. The civilization challenging nature of the magnitude of greenhouse gas emissions reductions needed to prevent dangerous climate change
  3. The barrier that the United States has been in international climate negotiations that have been ongoing since 1990 to achieve a global solution to climate change
  4. The essential ethical and moral nature of the climate change problem, a fact that has profound significance for policy formation
  5. The nature of the climate change disinformation campaign.

An Ethical Analysis of Mitt Romney’s Climate Change Views-Part Two

This is the second video looking at Mitt Romney’s statements on climate change through an ethical lens. In the first video, we examined critically Romney’s justifications for non-action on climate change that there wasn’t sufficient evidence that humans are causing warming and that the United States should not tackle the problem because it was a global problem. See:
