Ethical Issues with Relying on Natural Gas as a Solution to Climate Change

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 CO₂per 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.

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.

(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 2^oC 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 CO₂ 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 2^oC 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.

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.

An Ethical Examination of How The US Press Has Covered Links Between Hurricane Sandy and Climate Change

US President Obama and New Jersey Governor Chris Christie Inspect Damages from Hurricane Sandy., October 31, 2012

I-Introduction

In this paper we examine through an ethical lens how the controversy about links between Hurricane Sandy and climate change have been covered by the US media. In the last two weeks the mainstream media has awoken, at least temporarily, from a slumber about climate change because of the enormous damages from Sandy and their potential links to human-induced warming. Although this renewed attention to climate change should be welcomed, in the last entry on EthicsandClimate.org we identified several crucial missing features of climate change in the renewed press coverage of climate change that citizens need to know to understand why climate change is such a civilization challenging threat. These missing features include: (a) the nature of the strong scientific consensus about climate change, (b) the magnitude and urgency of the emissions reductions necessary to prevent dangerous climate change, (c) the barrier that the United States has been to finding a global solution for over 20 years, (d) the nature of the climate change disinformation campaign, and (e) the significance for policy of the fact that climate change is a civilization challenging ethical problem.

Ethicsandclimate.org has frequently explained the practical significance for policy of the fact that climate change is a civilization challenging ethical problem. We now look at the recent press coverage of the links between hurricane damage and climate change to identify how recognition of the ethical dimensions of climate change would affect the way the press covers links between hurricane damage and climate change.

II. Scientifically Understood Links Between Hurricane Sandy and Climate Change

Hurricane Sandy has produced a flurry of media activity on the possible links between climate change and the damage from Sandy in the Northeastern United States. For a sampling of various ways the US media has discussed possible ways of understanding this connection see the blog Residence on Earth: Articles about Hurricane Sandy and Climate Change.

Much of the press coverage makes the claim that there are links between Hurricane Sandy and climate change by pointing to the elevated ocean temperatures that have been caused by human-induced climate change, increased wind speed that is fueled by elevated ocean water temperatures, greater amounts of water that is transported into the atmosphere from the oceans in a warming world and dumped as rain during the storms, and rising sea levels that make storm surges worse.

Those opposing action on climate change often deny that one can link Hurricane Sandy to climate change.

A website whose mission is to oppose action on climate change, ClimateDepot, lists the following statements, among many others, of those who claim that there is no link between Hurricane Sandy and climate change:

Meteorologist Hoerling of NOAA: ‘The immediate cause is most likely little more than the coincidental alignment of a tropical storm with an extratropical storm. Both frequent W. Atlantic in Oct….nothing unusual with that’

Prof. Pielke Jr.: ‘We’ve done long-term trends with respect to hurricane damage in the United States, and it’s very safe to say that regardless of how [Sandy] plays out, there’s a century-long time series with no trend in it — and that’s in damage, the number of landfalls, or the intensity of storms at landfall. So, if you are looking for signals of long-term climate change, focusing in on any one storm is the wrong way to go about it to begin with’

Houston Chronicle’s Science guy Eric Berger: ‘…it is a big stretch to go from there to blaming Sandy on climate change. It’s a stretch that is just not supported by science at this time’

(Climatedepot 2012)

The mainstream scientific view on climate change, a view as we have previously explained in Ethicsandclimate.org that is supported by every Academy of Science in the world, almost all scientific organizations whose members have expertise relevant to climate science, and over 97% of scientists that do peer-review climate change science, holds that human-induced climate change is making the world warmer and sea level rise in predictable and measurable amounts. The mainstream view also holds that a warmer world will create more intense storms for a variety of reasons including that there will be more water vapor in the atmosphere in a warming world. There is now very strong evidence that the frequency of extreme weather events is increasing even if the record is not yet clear as to whether hurricanes are increasing in frequency.

Scientists know with high levels of certainty that climate change has increased Earth’s temperature, and that this warming has fueled more heat waves, more intense precipitation, more intense droughts, and more wildfires.

It is also true that scientists dont know for sure that climate change will make hurricanes more frequent but if hurricanes are formed they will increase damages because:

Higher sea levels will make storm surges more destructive

Warmer sea surface temperatures will fuel wind speed

Other potential links between Sandy and climate change are:

More moisture in the atmosphere causes larger amounts of rain fall
The unusual path of Sandy may have been affected by an unusual high pressure system which has links to climate change.

(Romm, 2012a)

As Joe Romm has stated:

The answer to the oft-asked question of whether an event is caused by climate change is that it is the wrong question. All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be….

(Romm, 2012a)

Because very destructive hurricanes existed before impacts from climate change were measurable, one cannot simply point to high damages alone from a hurricane and deduce that the damages by themselves unequivocally demonstrate the link between hurricane damages and climate change. However one can point to elevated sea levels and sea surface temperatures caused by climate change and conclude that the hurricane damages will on average increase because of climate change.

We therefore conclude that strong connections can be made about the damages to be expected from hurricanes even though one cannot attribute the initiation of any hurricane to climate change alone.

III. Ethics, Hurricanes, and Climate Change.

So far, almost the entire controversy created by Hurricane Sandy and its connection to climate change as discussed in the US media has been about whether one can attribute direct causation of Sandy to climate change. This is a scientific question and as we have seen there are strong scientific grounds for linking the magnitude of damages from Sandy to climate change, despite the fact that some uncertainties still remain about whether climate change increases the frequency of hurricanes. This issue has not been completely resolved.

Interest in the US press about whether there are links between climate change and hurricane damages appears to be motivated largely by the question of whether adopting climate change policies in the US will prevent even costlier damages to the United States. Most of the press coverage about links between Sandy and climate change follows this line of reasoning at least implicitly. That is the press coverage has treated issues about connections between Sandy and climate change as an issue of interest relevant to national calculations of costs and benefits that would flow from adopting climate change policies. Yet such reasoning ignores several ethical conclusions entailed by understanding that climate change could greatly increase harms to some. These conclusions are:

Those causing potential serious harms to others have duties and responsibilities to those that they may harm including those outside the United States, and not just economic interests in preventing harms to themselves,
It is not necessary to establish complete proof that one is harming others before duties to avoid potential harm to others are triggered. A person need only be on notice that his or her actions may be harming others to establish the duty to cease activities that could harm them particularly in cases where the harm to others is grave and the uncertainties cannot be resolved in a timely fashion before the harms are experienced.
The stronger the possibility that one may harm others, the greater the duty to avoid activities that may harm them.

This ethical reasoning exposes serious problems with how the press has covered the controversy about links between climate change and Hurricane Sandy. The press has treated the issue as if only two possibilities exist. Either there is a link between climate change and the damage caused by Sandy or there is no link. As we have seen this framing ignores the responsibilities of those putting others at risk that are entailed once it is established that links are likely. As we have seen, the science of climate change has long passed this threshold trigger for action.

The US press has also largely ignored likely ties to climate change when extreme weather events in the last few years have taken place in other parts of the world that have wrecked havoc on hundreds of thousands of people including killer floods in Pakistan, Brazil, China, and Australia. The Intergovernmental Panel on Climate Change issued a report in March of last year that linked climate change to increased extreme weather around the world including floods, heat waves, droughts, and heavy precipitation. (IPCC 2012). And so, the US press coverage of Hurricane Sandy can be criticized for not helping Americans understand links between their greenhouse gas emissions and other extreme weather damages around the world. High levels of greenhouse gas emissions in the United States are harming others around the world through extreme weather events.

The Grave US Media Failure to Communicate About The Consistent Barrier That The United States Has Been To Finding A Global Solution to Climate Change.

I. Introduction

This is the fifth in a series of articles that examines grave communications failures of the US media about 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 developed a video that summarizes these failures: Five Grave Communication Failures of 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/

This is the fourth paper that examines in more detail the issues briefly examined in the video. In previous entries we 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, and (c) the practical significance for policy that follows from understanding climate change as essentially an ethical problem. In this paper we look at the failure of the US media help educate US citizens about the consistent barrier that the US has been in international climate negotiations that have sought for over twenty years to find a global solution to prevent harsh climate change impacts.

The last paper in the series will examine the failure of the US media to help Americans understand the well-organized, well-financed climate change disinformation campaign.

II. The World Waits In Vain For US Leadership On Climate Change.

Most Americans are completely unaware that the United States has consistently been a barrier to achieving a global solution to climate change despite the fact that the United States is an indispensable party to a global climate change solution. To understand the importance of the US solving the global climate change problem, one must keep in mind that: (a) the United States is by far the largest historical emitter of global greenhouse gases that have caused the existing problem, (b) the United States is near the top of national greenhouse gas emitters on a per capita basis, (c) the United States is second only to China in total tons of greenhouse gases emitted, and (d) the United States has the worst record among developed countries in making commitments to a global climate change solution.

Although the United States is an indispensable participant in solving climate change because of the size of the US contribution to the global problem, the United States has a dismal record in over twenty years of international efforts to achieve a global solution to this civilization-challenging global problem. In American Heat, Ethical Problems With the United States Response To Global Warming, (Brown, 2002), this writer documented in detail the negative role in achieving a global approach to climate change that the United States played in the first decade of climate change negotiations from the late 1980s through the year 2000. Among other things during the negotiations of the United Nations Framework Convention on Climate Change (UNFCCC) between 1990 and 1992, the United States, virtually standing alone, successfully prevented the UNFCCC from including enforceable national emissions reductions targets for developed nations.

In a book to be published this month, Navigating the Perfect Moral Storm, Climate Ethics, this writer documents in detail the failure of the United States to be a leader since the conclusions of the UNFCCC negotiations in 1992, (Brown 2012).

Among other things, since the UNFCCC negotiations:

The United States has been the only developed country in the world to fail to ratify to the Kyoto Protocol and thereby commit itself to a binding interim emissions reduction target.
George W. Bush announced that the United States was not only unwilling to ratify the Kyoto Protocol, it was withdrawing the United States from the Kyoto Treaty all together.
When President Obama was elected, there was wide-spread hope the United States would change course on climate change. Yet, the United States under President Obama has approached climate negotiations in Copenhagen in 2009, Cancun in 2010, and South Africa making only a voluntary commitment to reduce its greenhouse gas emissions by 17% below 2005 emissions levels by 2020 thereby making the US promise: (a) the weakest of all of the developed country commitments, and (b) far short of what is required of global greenhouse gas emissions reductions necessary to prevent dangerous climate change.
Although there is evidence that President Obama hope to make the United States, for the first time, a responsible participant in an adequate global approach to climate change, since the Republicans took over the US House of Representatives in November of 2010, the United States hast been unable to make meaningful national commitments on climate change and will not likely to be able to do so until well into 2013 at the very earliest.
There is no evidence that the United States is willing to make commitments to reduce its greenhouse gas emissions to levels consistent with what the world needs to do to prevent dangerous climate change, a matter discussed in the second paper in this series.

Although there are several countries that have frequently failed to respond to what justice would require of them to reduce the threat of climate change, the United States, more than any other country, has consistently failed to respond to its ethical duties to reduce its emissions to the its fair share of safe global emissions during the over two decades that the world has been seeking a global agreement on how to respond to climate change.

Because the United States is such a vital player in any global solution to climate change, the United States response to its obligations to reduce the global threat of climate change has been an immense impediment to an urgently needed global climate change solution. And so the world continues to wait for ethical leadership from the United States on climate change as significant damages are becoming more visible around the world. As the world is running out of time to prevent significant climate change, the United States continues to ignore its global obligations. Yet coverage of climate change debates in the US media rarely mention the negative role the United States has been playing in developing a global solution.

The world awaits US leadership on climate change at a time when human-induced climate change harms are becoming more obvious. Yet there is little evidence that US citizens understand their obligations to poor people around the world for climate change damages and the United States has been significantly responsible for delays in reaching a global solution to climate change. This is both a tragic failure of domestic leadership and a failure of the US press to help educate Americans about the negative role the US has played in finding a global solution to climate change.

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 emissions. Because, 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 2^oC to avoid rapid non-linear impacts from climate change. The 2^oC warming limit was agreed to because there is widespread agreement among the vast majority of mainstream scientists that warming of more than 2^oC 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 2^oC because there is uncertainty about how the Earth will respond to different increases in temperatures. (Athanasiou and Bear 2002) The 2^oC 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 1^oC 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 CO₂must not only not be allowed to rise the small amount to 450 ppm CO₂ from current levels of 394 ppm CO₂but 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 CO₂reach 560 ppm of CO₂equivalent, where CO₂equivalent is the metric which translates other greenhouse gases into an equivalent level of CO_{2 .}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 CO₂is 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.
