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

national academy

 

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

This report is ethically significant because:

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

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

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

Justification 1

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

Report says:

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

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

Justification 2

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

Report says:

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

Justification 3

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

Report says:

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

 Justification 4

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

Report says:

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

Justification 5

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

Report says:

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

Justification 6

A few degrees of warming is not cause for concern.

Report says:

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

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

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

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

For these reasons, the new report is ethically significant.

Visuallizing Why US National and US State Governments’ GHG Reductions Commitments Are Now Woefully Inadequate in Light Of Recent Science.

Several charts produced by the Global Commons Institute vividly demonstrate the woeful inadequacy of both the US federal government’s and US states’ commitments on climate change in light of the most recent climate change science.

These charts are extremely important because there is virtually no discussion in the US press of the utter and undeniable inadequacy of commitments on climate change made by the US federal and state governments.

These charts help visualize complex information that is not well understood by the vast majority of US citizens, yet these facts  must be understood to comprehend the utter inadequacy of the US federal government and US state governments response to climate change. Thus, these charts help explain both why the US commitment to reduce its ghg emissions by 17% below 2005 as well as targets that have been set by even those US states which have shown some leadership on climate change must now be understood as utterly inadequate in light of the most recent climate change  science.

As we shall see below, in setting a government target for ghg emissions two clusters of issues need to be considered which have largely been ignored when US policy makers have set ghg emissions targets. One is the issue of global carbon budgets for the entire world needed to prevent dangerous climate change. We will call this the carbon budget issue. The second is the unquestionable need of all governments to set a target in light of that government’s fair share of safe global emissions. This is required by distributive justice. We will call this the equity or justice issue. All ghg emissions targets are implicitly a positions on the carbon budget issue and the equity and justice issue, yet policy makers rarely discuss their implicit positions on these issues and the US media is largely not covering the budget and justice issues implicit in any US policy on climate change. Any entities identifying a ghg emissions reduction target must be expected to expressly identify their assumptions about what remaining carbon budget and justice and equity consideration were made in setting the target.

I. The First Chart-US States’ Emissions Reductions Commitments Required to Prevent Dangerous Climate Change and Adjusted  To Take Equity Into Account.

The following chart depicts what US states emissions commitments should be to prevent dangerous climate change in light of the most recent climate change science and the need to take justice into account in setting ghg emissions targets. This chart can be examined in more detail on the Global Commons Institute website at http://www.gci.org.uk/images/Don_Brown_All_State_draft_[complete].pdf Clinking on this URL should access a pdf file that will allow for a closer inspection of this chart which can  be further enhanced by using the zoom function.

US states and federal reductions

What is most notable about this chart is that the US federal government and US state g0vernments will need to reduce their ghg emissions extraordinarily steeply in the next few decades, far beyond what has been committed to.  This chart, in combination with the next chart, helps visualize why the current commitments of even those US states which have demonstrated some considerable leadership on climate change need to be increased to levels that represent the state’s  fair share of safe global emissions.

a. The Carbon Budget Issue

These steep reductions commitments are needed in light of the most recent scientific understanding of the climate problem facing the world. A carbon emissions budget for the entire world is needed to prevent dangerous climate change and was identified by IPCC in 2013. This budget is of profound significance for national and state and regional ghg emissions reductions targets yet it is infrequently being discussed in global media and has virtually been completely ignored by the US media. To give the world an approximately 66% chance of keeping warming below 2 degrees C, the entire global community must work together to keep global ghg emissions from exceeding approximately 250 metric gigatons of carbon dioxide equivalent. The 250 metric gigatonne budget figure has been widely recognized as a reasonable budget goal by many scientists and organizations including most recently the International Geosphere Biosphere Program. The 250 metric ton number is based upon IPCC’s original budget number after adjusting for carbon equivalence of non-CO2 gases that have already been emitted but were not considered initially by IPCC. The practical meaning of this budget is that when the 250 gigtatons of carbon dioxide equivalent emissions have been emitted the entire world’s ghg emissions must be zero to give reasonable hope of limiting warming to the 2 degrees C. Since the world is now emitting carbon dioxide equivalent emissions at approximately 10 metric gigatons per year, the world will run out of emissions under the budget in approximately 25 years at current emissions rates. This is a daunting challenge for the world particularly in light of the fact that global emissions levels continue to increase.

A 2 degree C warming limit was agreed to by almost every nation in the world in international climate change negotiations in 2009 in Copenhagen because it is widely believed by the majority of  mainstream scientists that warming greater 2 degree C will create very harsh climate impacts for the world. In fact many scientists believe that the warming limit should be lower than 2 degree C to prevent dangerous climate change and as a result the international community has also agreed to study whether the warming limit should be lowered to 1.5 degree C. The report on whether a 1.5 degree C  warming limit should be adopted  is to be completed in 2015. In addition, some scientists, including former NASA scientist James Hansen who is now at Columbia University, believe that atmospheric concentrations are already too high and that atmospheric concentrations of ghg should actually be lowered from their current levels of approximately 400 ppm CO2 to 350 ppm CO2 to prevent dangerous climate impacts. If, of course, there is a consensus that the current warming limit should be lower than 2 degrees C, the slopes in the above chart would need to be even steeper.  (For a good introduction to the implications of the 2 degree C warming limit see the short video by International Geosphere Biosphere Programme)

Although there has been some very limited discussion of this in the US press, the staggering global challenge entailed by keeping global emission within a roughly 250  gigaton budget, not to mention a budget premised on 1.5 degrees C,  does not take into account the additional undeniable need of  high-emitting nations, states, and regional governments to take equity and distributive justice into account in setting ghg emissions reduction targets is not being covered in US media hardly at all.

b. The Justice or Equity Issue

Under any reasonable interpretation of what equity and justice requires, high-emitting nations and regions (including the United States federal government and US states) will need to reduce their ghg emissions at significantly greater rates than lower emitting government entities because of: (1) significantly higher per capita emissions in developed nations (2) the dramatically higher historical emissions of most developed countries compared to poorer countries, and (3) the need of poor countries to be able to aspire to economic growth rate that will get them out of grinding poverty. If equity is not taken into account in setting national ghg targets, poor countries will have their much lower per capita emissions levels frozen into place if national governments set targets based upon equal percentage reduction amounts. And so there are at least three very strong reasons why any target of a high emitting nation or state government must take justice into account in setting its emissions reduction target:

(1) Allocating emissions among nations to achieve a global target is inherently a problem of distributive justice. To not take justice into account in quantifying ghg emissions targets guarantees an unjust global response to climate change.

(2) All nations including the United States have already agreed to reduce their emissions based upon “equity,” not national self-interest when they ratified the United Nation Framework Convention on Climate Change.

(3) To not consider justice when a developed nation sets a ghg reduction target would be extraordinarily and obviously unfair to poor, low emitting nations, many of which are most vulnerable to the harshest climate change impacts and have done little to cause the existing problem.

The numbers in the above chart are based upon an equity framework known as Contraction and Convergence (C&C).  The C&C framework consists of reducing overall emissions of ghg to a safe levels from all nations (contraction) and each nation bringing its emissions eventually to equal per capita levels for all countries (convergence). Although justification of the C&C framework is beyond the scope of this entry, we will argue in a future article that it is the least controversial of all of the equity frameworks receiving international attention and therefore should be adopted by the international community as it can be adjusted to take other distributive justice issues into account not expressly initially considered in the C&C framework such as historical emissions and the need of poor-developing countries to grow economically. Because nations can negotiate the convergence date in the C&C framework, it is also a good tool to negotiate a global solution to climate change. It is therefore the least controversial of all of the equity frameworks under serious consideration by the international community although there are other equity frameworks that have some supporters including the Greenhouse Development Rights Framework (GDR). (We will explain our position on these issues in much more detail in a future entry.)

Yet, for the purposes of showing the utter inadequacy of existing US federal government and US state commitments, the C&C framework is very useful because other equity frameworks which have received some attention and respect in international discussions of what equity requires of nations would require even steeper reductions for the US and US state governments. For instance the GDR framework would require the US to be carbon negative by between 2025 and 2030. The C&C framework is therefore a very non-controversial way of demonstrating the utter inadequacy of developed nations ghg emissions reductions commitments because other equity frameworks would require even greater reductions from developed countries.

The above  chart demonstrates the implications of this recent science for US states as well as the inadequacy of the US federal government commitment in light of a total global budget limitation of approximately 250 gigatons of carbon equivalent emissions.. The steepness of the curves in this chart are driven both by the limitations of the 250 gigaton carbon equivalent budget and the need to take equity into account. (The Global Commons Institute has  a computer graphic tool on its web site, the Carbon Budget Accounting Tool, that allows those who would like to consider alternatives to the 250 gigaton budget to visualize the effects of other budget numbers on the shape of the ghg  reductions pathways needed, the differences in environmental impacts, and  many other policy considerations.)

Like any attempt to determine what a ghg national target should be, the above  chart makes a few assumptions, including but not limited to, about what equity requires not only of the United States but of individual states, when global emissions will peak, and what the carbon emissions budget should be to avoid dangerous climate change. Although different assumptions would lead to different slopes of the emissions reductions pathways that are needed to remain below the 250 gigaton global carbon limitation, the chart depicts very reasonable assumptions about what needs to be done to stay within the 250 gigaton carbon equivalent budget while taking equity into account. And so, without doubt the US government and US state’s targets are woefully inadequate. To stay within the 250 gigaton carbon equivalent budget, total US emissions which will be comprised of emissions from all states must achieve carbon neutrality by 2050. Even the most aggressive US state targets are woefully short of this goal. In addition most US states have no emissions reduction target at all. The US will need to achieve carbon neutrality by 2050, and this national requirement will will require US states to work together to achieve carbon neutrality. The US government could achieve the goal of reaching carbon neutrality by 2050 by relying on different approaches in different states, yet the individual states must assume they have a duty to limit their ghg emissions to levels that constitute their fair share of safe global emissions and in the absence of a federal plan that would allow them to do otherwise, states must achieve zero carbon emissions by 2050 and the above chart is a good example of what is required of them in total.

 II. The Second Chart-US States Existing Commitments Compared to an 80% Reduction By 2050. 

A few states have set ghg emissions reduction targets of 80 %  by 2050. The next chart shows the quantify of reductions that each state would need to achieve to reach an 80% reduction by 2050 although we have already established above that the most recent science would require each state to achieve carbon neutrality by 2o50.

states 80 percent

This chart can be examined in higher resolution on the Global Commons Institute website at: http://www.gci.org.uk/images/Emissions_Cuts_States_by_State.pdf

What is notable about this chart is that most US states have made no ghg emissions reductions commitments at all, only a few have made a commitment of an 80% reduction by 2050 which is still not stringent enough to meet the goal of carbon neutrality by 2050, and that some states such as Texas need to achievehuge emissions reductions if the US is going to do its fair share of staying within the 250 metric gigaton carbon equivalent budget.

III. Conclusions

These charts help visualize the enormity of the challenge facing the United States federal government and US state governments in light of the challenge facing the world as understood by the vast majority of mainstream scientists. There has been almost no coverage of this reality in the US media.

As explained above, there are two kinds of issues that need to be understood to comprehend what governments must do when setting ghg emissions targets. The first is the need to set any target in light of a total global ghg emissions limitation or budget entailed by the need to limit ghg emissions to levels that will not cause dangerous climate change. This, as we have seen,  is sometimes referred to as the carbon budget issue. The second is the need of governments to set their emissions target only after considering what distributive justice requires of them. This sometimes referred to as the equity or justice issue.  Any propose ghg emissions target must take positions on

these two clusters of issues in fact they implicitly do this. Yet government rarely explain what assumptions about the carbon budget and equity and justice issues they have made when setting their target.

US Media Finally Acknowledges That Ethics and Justice Issues Are At the Center of Contention in Climate Change Negotiations, Yet Has Not Caught On to the Significance of This for US Policy.

 

climate justicenow

During the climate negotiations in Warsaw that concluded late Saturday, some of the most prominent US media institutions  finally acknowledged that ethics and justice issues were at the very center of the most contentious issues in dispute.

For instance, the New York Times ran a story on November 16 entitled: Growing Clamor About Inequities of Climate Crisis. This article expressly acknowledged that growing demands about ethics and justice have become an emotionally charged flash point at the Warsaw climate negotiations

The Washington Post reported that: Hundreds of activists march for climate on sidelines of UN talks in Warsaw and in this story there was acknowledgment that the ethics and justice issues were the central focus of unresolved issues on national ghg emissions reduction commitments and funding needed funding for poor, vulnerable nations for adaptation and climate change caused losses and damages.

Bloomsberg News also ran a story entitled:  U.S., EU, Reject Brazilian Call for Climate Equity Metric. This story described great disagreements among nations on how to allocate national emissions targets on the basis of equity.

This recent recognition of the importance of ethics and justice issues in international climate change negotiations marks a possible sea change in on how the US press has thus far covered international climate change issues. Yet it is too early to predict such a transformation will actually take place and reason to believe that the US media still does not understand the practical importance for US climate policy that an ethical focus on climate change entails. In fact there is no evidence that the US press understands the policy significance for the US if climate change is understood as a civilization challenging global distributive justice problem.

As we have frequently reported in EthicandClimate.org  over the last several years, (See articles on the website on the US media in the Index), the US media has been utterly ignoring the climate change justice issues that increasingly have become the most contentious issues in dispute in the international search for a global solution to climate change.

movbilization for clima justice

Although there has been a US press presence at international climate negotiations since they began over 20 years, the US media reports on the climate negotiations has usually focused on the failures and small success of previous negotiations. Also, sometimes the US press also has reported on specific disagreements among nations on contentious issues in negotiations. And so, the US media has covered climate negotiations like they would a baseball game, that is they usually focus on the score, who batted in the runs, and who prevented runs from scoring.

In the meantime, during the debates about US domestic policy on climate change that have been taking place for almost thirty years, the US media has reported on climate issues almost exclusively by focusing on issues of scientific certainty about climate change impacts and economic cost to the US economy.  This phenomenon is partly attributable to the fact that economic interests opposed to US climate change policies have skillfully and successfully framed the US climate change debate as a matter about which there is insufficient scientific evidence or too much adverse impact on the US economy to warrant action. And so, although climate change is a civilization challenging problem of distributive justice, the US media has largely ignored the justice issues particularly in regard to their significance for US policy. For  instance, if the the US not only has economic interests in the climate change policies in political debate but also obligations and duties to poor vulnerable nations to not cause them great harm from US ghg emissions, the United States may not justify failure to act to reduce its ghg emissions on the basis of economic cost to the US.

Yet now that the scientific community is telling the world that is running out of time to prevent dangerous climate change and that there is a very small amount of ghg emissions that can be admitted by the entire world if the international community seeks to have any reasonable hope of avoiding dangerous climate change, the ethics and justice issues are becoming undeniable and it is almost possible to ignore that the ethics and justice issues are at the very center of international disputes about how to structure a global climate solution. And so, cries about the justice issues will mostly likely continue to become louder in the future. This is so because if the entire global community must limit total global ghg emissions to a specific number of tons of ghgs and this number requires radical ghg emissions reductions from the entire global community, the obvious question becomes what is any nation’s fair share of allowable emissions.  And so, issues of climate justice may no longer be ignored, in fact, the longer the world waits to arrive at a global solution to climate change the more important and visible the ethics and justice issues will become. For this reason, it will become more and more difficult for the US press to ignore the practical significance of ethics and justice questions.

new book description for website-1_01At the center of the Warsaw negotiations was not only the question of what was each countries fair share of safe total allowable greenhouse gas submissions, but also what does justice require of high-emitting  countries to both pay for the costs of climate adaptation and compensation for damages for poor vulnerable countries that have done very little to cause climate change.

And so this new interest in ethics and justice about climate issues could become a growing media focus. However, this recent new interest of the US media is not evidence that the US press has begun to pay attention to the implications of these issues for US climate change policy. In fact, there is no evidence that the US media has figured out how the ethics and justice issues will need to radically transform how domestic climate change policy is debated in the United States. We will know that the US media this is seriously paying attention to the ethical dimensions of climate change if it examines the following questions when it covers US climate change policy debates.

1. What is the ethical justification for any proposed US greenhouse gas reduction target in light of the fact the US has duty to reduce its emissions to the US fair share of safe global emissions. In setting a ghg emissions reduction target, what ethical obligations to nations and people outside the US has it taken into account.

2. If the United States is a very large emitter of gigs compared to most other nations in terms of historical and per capita emissions, why doesn’t the United States have an ethical duty to fund reasonable climate change adaptation measures in and losses and damages of poor developing countries that have done little or nothing to cause human-induced warming.

3. If a US politician argues in opposition to proposed US climate policies on the basis of cost to the US economy, why doesn’t that politician acknowledge that in addition to US economic economic interests, that the United States has duties to people around the world and future generations to reduce ghg US emissions.

4. If United States actually has ethical duties for the rest of the world to reduce its ghg emissions to its fair share of safe global emissions, why is there no national policy encouraging everyone in the United States including individuals and corporations to reduce unnecessary ghg emissions.

5. On what basis may the United States argue that it need not reduce US ghg emissions to its fair share of safe global missions because China or some other developing country has not yet adopted strong climate change policies, given that any US ghg emissions in excess of the US fair share of safe total omissions is harming hundreds of thousands of people around the world and the ecological systems on which life depends.

Ethical and Justice Issues In Contention At the Warsaw Climate Negotiations-The First In A Series Of Reports.

warsaw

 

Negotiations on the international climate regime have begun in Warsaw at a time when the scientific community, including the IPCC in its recent report on the Physical Basis for Climate Change Science and UNEP in its just released Emissions Gap Report, are advising the international community that the world is running out of time to prevent dangerous climate change.

The Warsaw agenda includes numerous topics that raise profound ethical and justice issues which not only must be faced to achieve a global climate change solution but which are also increasingly at the center of the most contentious issues in the international climate negotiations. Despite this fact, the international media, at least in most developed countries, is utterly failing to report on the ethical and justice dimensions of issues that are so central to achieving a favorable outcome in Warsaw. The failure of the media to continue to report on these issues almost guarantees that nations will continue to ignore their ethical obligations, a prospect which surely dooms the development of an adequate global climate regime.

This is the first entry in a multi-part series which will first examine the ethical dimensions of major issues under consideration in Warsaw and then, at the conclusion of COP-19, report on what was accomplished in Warsaw on these ethical issues.

Among Warsaw issues examined in this series through an ethical lens will be:

1. The extent to which nations make ghg emissions reductions commitments based upon “equity” rather than national interest alone.

2. The willingness of nations to agree to a new treaty that is to be completed in 2015 and that comes into effect in 2020 that includes a format for emissions reductions that takes equity and justice seriously.

3. The willingness of high-emitting nations to finance adaptation and climate change reduction strategies in vulnerable, developing counties.

4. The willingness of those nations most responsible for human-induced warming to agree to finance the value of losses and damages from climate change that can’t be avoided.

5. The extent to which some nations more than others are barriers to an urgently needed global climate change treaty.

6. The willingness of nations to accept a new climate change treaty that is sufficiently legally binding that it provides adequate sanctions for those who do not comply with their promises.

The next entry in the series will look at the ethical issues entailed by the need for national emissions reductions commitments to be based on “equity” and “justice”.

US Media Fails to Educate The Public About Links Between Greater Natural Gas Use and Climate Change

methaneleakageThe New York Times and the Wall Street Journal  today reported on a new study by the University of Texas that found leakage rates of methane from natural gas fracking operations are lower than previously stated by US EPA. This report found that direct measurements of methane emissions from  190 onshore natural gas sites in the United States indicate that methane emissions from completed wells are are  lower than commonly thought although the report also acknowledged that emissions from pneumatic controllers and other equipment associated with natural gas production facilities were higher than previously estimated.

The report also concluded that taking into account the lower emissions from completed wells and the higher emissions from other equipment, actual methane emissions are most likely 20% lower than previously estimated.

This report has created a large buzz on the internet because at issue is whether natural gas is a bridge fuel to lower the threat of climate change. If the methane leakage rate is less than 3.6%, then it is widely assumed that natural gas is better than coal.  That is, if leakage levels are below this level it is generally assumed that switching to natural gas lowers the US carbon footprint and therefore greater natural gas production should be supported by citizens concerned about climate change. As a result the methane leakage rate issue has gathered enormous interest in climate change policy discussions.. Studies of methane leakage rates have reached widely different conclusions about actual leakage rates in part because different studies have used different: measurement methodologies, types of wells measured, portions of the the entire natural gas production process, and assumptions about leakage in the gas distribution process. The recent University of Texas study acknowledges that there are elements of the natural gas production to consumption cycle that were not fully considered.  And so, it is likely that scientific conclusions about methane leakage rates will continue to change from study to study in the next few years.

Because natural gas may produce less CO2 equivalent per unit of energy produced, natural gas companies are pushing natural gas as at least a short- to medium-term solution to climate change

Yet, as we have written about before, there is one extraordinary important issue about the link between natural gas production and climate change that is rarely being reported on in the US press nor is it usually part of the US debate about natural gas fracking and its impact on climate change.

The methane leakage debate usually assumes if the methane leakage rate is low enough, switching from coal to natural gas as fuel should be welcomed by proponents of action on climate change. Yet what is notably missing in the media discussion of this issue is the urgency of moving to non-fossil fuels or energy technologies that produce very, very low carbon emissions to give the world any hope of prevent catastrophic climate change.

We explained the  urgency of moving quickly to non-fossil energy in considerable detail in the recent entry on this website in  Ethical Issues with Relying on Natural Gas as a Solution  to Climate Change

Even if natural gas combustion creates approaching 50 percent less CO2 equivalent per unit of energy produced, an amount which is well beyond best case on ghg emission reductions,  it will not create the much greater emissions reductions necessary in the next 30 years to give any hope of  limiting warming from exceeding levels that will cause catastrophic impacts.  In short, natural gas combustion can’t produce the the emissions reductions that are needed just a few decades to put the world on a safe ghg emissions pathway.  Also investment in natural gas facilities may delay the needed rapid switch to non-fossil fuels. Although natural gas switching might help reduce the threat of climate change threat if  methane leakage rates are at the lower end of the range discussed  in the scientific literature in the very short term, the world needs 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 in putting the world on an urgently needed ghg emissions reduction pathway needed to prevent catastrophic warming.

nw book advIn addition, large investments in natural gas combustion facilities will likely make it harder to switch to non-fossil energy because these investors will likely demand a return on their investment in the natural gas plants before they are shut down.

Large investment in cheaper natural gas may also increase energy demand to levels that result in greater total releases of ghgs even assuming that natural gas produces less CO2 equivalent on a BTU basis than coal.

It is simply irresponsible for the US media to report on the methane leakage issue without explaining the urgency of moving to non-fossil energy.

Of great concern, some natural gas companies are on the one hand claiming that natural gas is better for the climate change while they fight legislation to increase the US share of renewable energy.  A strong ethical case can be made that any political support for natural gas as a short-term bridge fuel  should be conditioned on the natural gas industry promising to stop lobbying against rapid scale up of renewable energy programs.

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

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

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

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

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

In response to climate skeptics he said:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

imhoff

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

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

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

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

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

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

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

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

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

Equity Remains At The Center of Bonn Climate Change Talks

 

equity and climate change

 

In a recent article in Ethicsandclimate.org, we explained why there is an urgent need of nations to respond to climate change be reducing their greenhouse gas emissions to levels required of them by “equity” to give the world any hope of  limiting warming to tolerable amounts. On the Extraordinary Urgency of Nations Responding To Climate Change on the Basis of Equity

This article was written to explain in simple terms why national responses on the basis of equity are an indispensable ingredient in any global solution to climate change.  This article was also written because the media in the United States and other parts of the world are utterly failing to explain the importance of equity in national responses to climate change. This failure makes it easier for economic interests who perceive that they will be harmed if a nation reduces  its carbon emissions to manipulate the public with such arguments as the United States should not reduce its emissions because China is the largest polluter in the world. Citizens around the world need to understand that all nations have a duty to reduce their emissions to levels required of them by equity regardless of what other nations do to retain any reasonable hope of finding a global solution to climate change.

Since posting this article, nations have met under the United Nations Framework Convention on Climate Change (UNFCCC) in Bonn in early May, 2013 and in the first two weeks of June. In these meetings, equity continued to be a major focus of concern because of increasing scientific awareness of the urgent need of nations to increase their ambition in their greenhouse gas (ghg) emissions reduction commitments to have any hope of preventing dangerous climate change.

Equity was not the only important issue under consideration at the Bonn  new book description for website-1_01meetings. Other significant issues under discussion were loss and damages, REDD (reducing emissions from deforestation and forest degradation), market mechanisms under the UNFCCC, NAMAs (nationally appropriate mitigation actions for developing countries), and technology transfer, and completion of the architecture for the second commitment period under the Kyoto Protocol.

However, perhaps the most important issues in discussion in Bonn were those relating to structuring a new global climate change treaty that the world has agreed to complete by 2015 in Paris under the Ad Hoc Working Group on the Durban Platform referred to by acronym ADP. These discussions focused on finding agreement on pre-2020 ambition national emissions reductions commitments and a framework for post-2020 agreement, carried out in two different work streams.

Parities working under the ADP are working to get a comprehensive deal by the 2015 deadline. The Bonn meeting marked the beginning of that “road to Paris” where 2015 COP-21 that is expected to finalize a new climate change agreement with legal significance that will come into force in 2020 .

equity and ambitionParties at the May Bonn meeting stressed the need for nations to align their commitments on the basis of  equity as required by the UNFCCC.  During the May Bonn meeting some developing countries argued in behalf of a proposal by Brazil that developed countries must take the lead on emissions reductions that took into account historical responsibility.

Other equitable frameworks were also discussed in May including frameworks known as “contraction and convergence,” “greenhouse development rights,” the “Indian Proposal,” and others.

There was also discussion on a new framework that is based upon the idea that all people everywhere should have the same right to use global atmospheric space.

A number of Parties spoke of the urgent need to close the ambition gap, as well as the quantification of the amount of adaptation that will be required in the light of the current scientific assessment of adaptation needs should current commitments not be met.

At the just concluded Bonn meeting in June, there was very little progress made in getting nations to increase their ambition based upon equity or on agreement about what equity requires. Although the June Bonn meeting saw some modest  progress on a few issues including REDD, little progress was made on the substantive content of future national commitments under the new treaty to be negotiated by 2015.  These issues will be taken up again in Warsaw at the next conference of the parties under the UNFCCC in mid-November.

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

natural gas

 

Is Natural Gas Electricity Combustion A Solution to

 

 

 

 

 

 

 

 

 

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 most 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.

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.

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

 

Climate Change Is  Real, Yet The US Press Is Not Reporting On The Urgency and Magnitude of the Problem

 

One can tell by how climate change policies are being debated around much of the world that few people, including many very educated people,  understand the scale and urgency of the problem now being articulated by the most prestigious scientific international institutions.  In this writer’s experience this is true not only of average citizens but also of most college students and academics that are not enrolled in climate science courses and by almost all press that periodically reports on this issue.

This entry describes what needs to be understood to evaluate the adequacy of the US response to climate change although the analysis contained here could be applied to almost any nation in the world. This is so because the adequacy of any national response to climate change must now be examined in light of the scale of the problem, yet few people understand the magnitude and urgency of this enormous threat.

In the wake of Hurricane Sandy and reports that 2012 was the warmest year in US history, climate change has been more visible in the US press recently.  Yet despite this increased attention, for the most part, the urgency and magnitude of the need to reduce greenhouse gas emissions entailed by the mainstream scientific understanding of this civilization challenging problem is not being covered by the US press.

In fact, some of the recent climate change reporting could be understood as actually misleading US citizens that the United States is making acceptable progress in reducing the threat of climate change. For instance, a Scientific American Report of October 2012 was titled: “U.S. May Come Close to 2020 Greenhouse Gas Emission Target“. This article said that the United States is likely to reduce its greenhouse gas emissions by 16.3 % from 2005 levels by 2020, falling just shy of the 17 % target pledged by President Obama at the 2009 climate talks in Copenhagen, Denmark.  Other projections of US emissions have found, however, that although the US emissions are dropping compared to 2005, it is not likely that the US will come close to achieving the 17% reduction goal without further legislative action because current reductions will lead a best to a 9% reduction by 2020. (See, for instance, WRI report)

For instance, the following graph from the World Resources Institute includes a projection of future US greenhouse emissions that predict US emissions will flatten out above the 17 % reduction goal by 2020.

(WRI, 2012)

Some media reporting on US emissions reductions leave the false impression that the United States is performing well in meeting its responsibilities to reduce greenhouse gas emissions because it is possible for the US to come close to meeting a US commitment made in Copenhagen in 2009 to reduce its emissions by 17% below 2005 emissions.  Missing from such reports is an analysis of projected US emissions reductions compared to the magnitude of global greenhouse gas emissions reductions needed to prevent catastrophic warming and the limited amount of time that the international community has to put global emissions on a reduction pathway that has some hope of avoiding rapid non-linear climate change.  That is, to evaluate the US performance in reducing its greenhouse emissions one must compare US emissions both at existing and future commitment levels with what is needed globally to avoid harsh impacts.

The following chart shows the emissions reduction commitments individual nations have made thus far including the United States and what emissions are projected if the United States meets its projected target (there are two numbers shown on this chart for each commitment to take into consideration certain contingencies).

 

(UNEP 2012)

This chart shows that the US commitment is among the lowest emissions reductions from 1990 levels compared to other developed nations.

The following chart compares total emissions from major national emitters  in regard to 1990, 2005, 2010, business as usual,  and projected emissions in 2020 and projected based upon emissions reduction commitments.

Although China will soon be emitting total emissions at levels twice as much as the United States, the following chart demonstrates that the US will still lead even China in per capita emissions.

To make sense of the performance on greenhouse gas emissions of any nation one must understand the magnitude of greenhouse gas emissions reductions necessary to prevent catastrophic warming.

The international community has agreed that future warming should be limited to 2 degrees C because greater warming is believed to create a risk of passing tipping points in the climate system that will trigger rapid increased warming with devastating consequences. Given this there is now a strong scientific consensus that the entire global community must limit its greenhouse gas emissions by as much as 25% to 40 % below 1990 emissions levels by 2020 to have any reasonable chance of avoiding dangerous climate change and that global emissions are still increasing between 2% and 3% per year, the challenge to the international community in regard to magnitude of emissions reductions needed is staggering. And so any national commitment to reduce greenhouse gas emissions must now be evaluated by examining whether the commitment is ambitious enough to prevent dangerous climate change given what is the nation’s fair share of safe global emissions.  A simple comparison of the US commitment with needed global emissions reductions clearly reveals that the US promise is woefully and utterly inadequate.  That is, the US commitment of 17%  below 2005 emissions is only a 4% reduction below 1990 emissions levels making it among the weakest of the developed nations’ promises to reduce emissions and far below of global emissions reductions needed to prevent rapid climate change.

Moreover, 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 40 years. The following chart shows the emissions reduction pathways that are needed in this century to give the world any hope of limiting warming to 2 degrees Centigrade. The later the peaking of global total emissions, the steeper the reduction pathways that are needed. (The different colored lines represent different emissions scenarios in the years ahead)

 

(Anderson, K.  2011)

 

And so, the US projected emissions reductions fall far short of the 25 to 40 %  emissions reductions below 1990 levels by 2020 that are likely necessary to put the world on a pathway that gives any hope of limiting warming to the dangerous 2 degree C warming limit that has been agreed to. Furthermore there is some inconclusive evidence that to prevent dangerous climate change the warming limit should be 1.5 degrees C, a matter that will  be investigated under the UNFCCC in the next few years.

If a 1.5 degrees C warming limit should be the goal of the international community rather than 2 degree C, the international community will need to dramatically increase it emissions reductions ambitions to hard to imagine levels.  In fact, all of the commitments made by all nations under the UNFCCC fall far short of the emissions levels necessary to prevent the 2 degree C warming limit . The following chart describes the gap between the emissions reductions commitments that nations have been made under the UNFCCC.

 

According to a recent report by the United Nations Environment Program, to have any chance of limiting warming to 2 degree C total levels in 2020 must be no greater than 44 GtCO2e (with a range of: 41-47 GtCO2e). Afterwards, global emissions must steeply decline (a median of 2.5% per year, with a range of 2.0% to 3.0% per year) to 2050.

Because current global greenhouse gas emissions, based on 2010 data,  are estimated at 50.1 GtCO2e the world is emitting emissions 14% higher than the median estimate (44 GtCO2e) of the emission level in 2020 needed to have any hope of limiting warming to the 2 degree C target and global emissions are currently increasing at 2 to 3% per year, the world is running out time to prevent dangerous climate change.  (UNEP, 2011).

The following chart demonstrates the enormity of the challenge after 2020 to limit warming to 2 or 1.5 degrees Centigrade.

(CAN presentation)

Not only must global greenhouse gas emissions be reduced at difficult to imagine rates to avoid dangerous climate change, the United States must exceed these global reduction rates for two reasons according to any sense of basic fairness. First, US per capita emissions are among the highest in the world as we have seen above.  Second, the United States also exceeds all countries in the world in historical emissions. The following chart shows the proportion of global greenhouse gas emissions being emitted by the United States since the beginning of the industrial revolution.

 

Therefore the US will clearly need to reduce its emissions to even greater levels than those required of the entire world because its per capita emissions are higher than almost all nations and its historical emissions have disproportionally contributed to the elevated atmospheric greenhouse gas concentrations already causing some climate change harms. And so, the United States is challenged to make rapid reductions in greenhouse gas emissions greater than most any other country. This is not only an ethical obligation, it is foundational to any hope of avoiding harsh climate change.

The US media has utterly failed to report on the scale of this challenge. Educators around the world have also largely failed to educate civil society about the urgency of action on climate change. To minimize the threat of climate change, the world needs an “all-hands-on-deck” approach to climate change that is mindful of the scale of the challenge.
