Activity: Extended Writing

The following is from Nature.com

Climate Change as a Challenge to Ethical Action
Climate change has been described as a "perfect moral storm" because it brings together three major challenges to ethical action in a mutually reinforcing way (Gardiner 2011a). The first challenge stems from the fact that climate change is a truly global phenomenon. Once emitted, greenhouse gas emissions can have climate effects anywhere on the planet, regardless of their source (IPCC 2007). This is often said to result in a prisoner's dilemma or tragedy of the commons structure played out between nation states: although collectively all countries would prefer to limit global emissions so as to reduce the risk of severe or catastrophic impacts, when acting individually, each still prefers to continue emitting unimpeded (e.g., Soroos 1997, Helm 2008, but see Gardiner 2011a). At the same time, there are skewed vulnerabilities: at least in the short- to medium-term, many of the most vulnerable countries and people are those who have emitted the least historically, and whose emissions levels continue to be relatively low. This appears to be seriously unfair and casts a notable shadow over both practical and theoretical efforts to secure global cooperation.
The second challenge is that current emissions have profoundly intergenerational effects. Emissions of the most prominent greenhouse gas, carbon dioxide, typically persist in the atmosphere for a long time, contributing to negative climate impacts for centuries, or even millennia (IPCC 2007). This too seems unfair, especially if future negative impacts are severe and cumulative. In addition, the temporal diffusion of climate change gives rise to an ethical collective action problem that is even more challenging than the traditional tragedy of the commons both in its shape and because normal kinds of cooperation do not seem to be possible across generations.
The third challenge to ethical action is that our theoretical tools are underdeveloped in many of the relevant areas, such as international justice, intergenerational ethics, scientific uncertainty, and the appropriate relationship between humans and the rest of nature (e.g., Jamieson 1992). For example, climate change raises questions about the (moral) value of nonhuman nature, such as whether we have obligations to protect nonhuman animals, unique places, or nature as a whole, and what form such obligations take if we do (see, e.g., Jamieson 2003, Palmer 2011). In addition, the presence of scientific uncertainty and the potential for catastrophic outcomes put internal pressure on the standard economic approach to environmental problems (e.g., Sagoff 2007, Stern 2007, Gardiner 2011a), and play a role in arguments for a precautionary approach in environmental law and policy that some see as an alternative (see, e.g., Sunstein 2005, Whiteside 2006).

As you are now an expert on climate change in every aspect, choose an extended writing topic to complete.  This will require further research on your part, so be sure to cite any sources you use. Some topics will require creative thinking, others more deductive research and reasoning. Some will require you to think critically and apply an ethical framework to the topic.  Be thorough in your coverage of the topic.  The following is a list of ideas or questions to begin your investigation. Produce a thorough examination of your chosen topic and be sure to think critically and consider all points of view, including the ethical implications of the topic.

  • How can MEDCs help developing nations become more developed without following the MEDCs path as far as greenhouse gas emissions is concerned?
  • Should population control in countries with rapid population growth be required or encouraged?  What are the ethical implications of this action?  Are there more ethical ways of encouraging slower population growth?
  • Should LEDCs be required to lower greenhouse gas emissions?  Is it ethical for developed countries to force limitations on developing nations?
  • What is geoengineering?  What are some of the ethical issues surrounding geoengineering and climate change?  Are geoengineering reasonable?  What could their long term impacts be?
  • Should the onus for climate change mitigation and adaptation strategies be placed equally on all nations?  Should it be distributed differently?
  • Should MEDCs be required to lower their standard of living and consumption habits in order to be more equal with the rest of the world?

Activity: Climate Change Mitigation Action


Climate change mitigation are things which are being done to limit the causes of climate change. These things tend to focus on efforts to curb carbon emissions, especially in the developed world.
Investigate and explore the following sources.  Pick one sector of the economy, agriculture, transportation, construction, etc., and investigate current and proposed various strategies of reducing greenhouse gas emissions.  Read actual climate mitigation strategies written by the governments and organizations which are creating and implementing them.

http://unfccc.int/focus/mitigation/items/7169.php



Read this website on the Kyoto Protocol and review the function of the agreement in terms of climate change mitigation.  Pick one of the three mitigation mechanisms (International Emissions Trading, Clean Development Mechanism or Joint implementation) and review how the mechanism works.  Research articles which are in favor of that particular mechanism and summarize the reasons the article states for being in favor of it.  Research articles which disagree with that particular mechanism and summarize the reasoning behind the article.

Now, form your own opinion.  Journal answers to the following questions.  Overall, do you think that mechanism is positive and useful? Can you see some of its shortcomings and faults?  Do you think that the mechanism is within the purview of the UN to create?  What are the ethical dilemmas at play?

Case Study: India

India's current population is 1.2 billion and is projected to rise to 1.5 billion by the middle of this century.  India's population is overall young, with nearly half of the population under the age of 25.  It's infant mortality rate is 4.5% and the life expectancy is 67 years.  The majority of it's labor force is involved in agriculture and a third of the population lives in urban areas.

Using reputable sources on the internet, beginning with those listed below, research an example, or case study, of one aspect of the impact climate change is having in India.

http://www.clraindia.org/include/Climate.pdf
http://www.oecd.org/env/cc/36426827.pdf

First, write a summary of the particular case study which you examined in detail.  Next, complete one of the following two assignments.
1-Pretend you are writing a research proposal for an NGO or university.  Propose one aspect of the impact climate change is having in India which you would like to investigate.  Be specific, list particular places or regions of India in which you would like to conduct your research.  Give facts and details about the situation and explain why you think it is a valid research subject, creating/finding graphs and maps to help support your proposal.  Describe your proposed method for research; is it data analysis or field work, quantitative or qualitative, or both?

2-Pretend you are a delegate from India at the next round of climate change talks hosted by the UN. Prepare a presentation of your findings, as well as the findings of other case study research, about how climate change is impacting India.  Be specific, describing actual case studies.  Create/find graphs and maps to help support your presentation.  Additionally, research and present some of the things India is doing to mitigate climate change by reducing greenhouse gas emissions.  Also, research and present some of the things India is doing to adapt to climate change on the national, regional, and local level.

Activity: Population and Climate Change

The world population grew from 1.6 billion to a staggering 6.1 billion people during the 20th century. All of these people use resources everyday.  Population projections suggest that the global population will reach 9 billion in the middle of this century.  It is obvious that as population increases, so too will demand on resources increase, as well as greenhouse gas emissions.  Watch the video below, and pay attention to what Hans Rosling says about greenhouse gas emissions.


Hans Rosling states that the populations of wealthy Western countries must be able to share the resources and carbon emissions with 10 times their current populations by the middle of this century.  Using your imagination, describe this future world of 9 billion people in your journal. You will be around middle age at this point, halfway through this century. What does life look like in the UK?  What is life like in China, The Gambia?  What are the mitigation and adaptation strategies in use for dealing with climate change?  

Developing Nations and Climate Change

Source: New York Times
As nations experience economic development, historically they follow a similar path toward development as the MEDCs.  This includes an increase in fossil fuel burning for electricity, automobile use and therefore emissions, industrial production, and intensive agricultural production.  The worlds two biggest developing economies, India and China, do not vary from this historical model.  

Source: EPA
They are amongst the highest carbon emitting countries in the world, and are projected to continue along this path into the future. With their large and growing populations and their rapid economic development, greenhouse gas emissions are only expected to increase.
Source: Stockholm Environment Institute
Developing nations sometimes view it as their right to burn the necessary fossil fuels to achieve economic development.  The most economically developed nations had opportunity to develop without restriction, so the questions is why can't they do the same?
Both India and China, however, are signatories to the Kyoto Protocol (a UN agreement on restrictions to greenhouse gas emissions) but did not sign on to any binding targets.

India's and China's populations are projected to continue to increase in the coming decades.

Curbing emissions whilst increasing economic development can be difficult and, more importantly, expensive, even for developed nations.  Sometimes countries aren't interested in the difficulty and expense.  While these countries are currently high emitters of greenhouse gases, they are relatively new on the scene and haven't been producing huge amounts of greenhouse gases for as long as the MEDCs.  The question becomes, if greenhouse gases have an additive effect on global warming, shouldn't all historical emissions be added up and considered rather than simply emissions year on year?

Activity: Feedback Loops

The previous post ended with a question: What happens to Earth's albedo when, as we know from the previous post, surface ice cover starts decreasing?

The effect this loss of ice has on Earth's albedo creates something called a positive feedback loop. A feedback loop is when the effect of one process changes another process so that it impacts the effects of the initial process.  A positive feedback loop encourages the cycle, a negative feedback loop inhibits or stops the cycle.

Source: EPA
The loss of Arctic sea ice is of utmost concern for climate scientists as it creates a positive feedback loop.  The speed and extent to which this feedback loop with have an effect on Arctic sea ice and overall climate change has yet to be seen.

The Ocean-Atmosphere Carbon Cycle is another climate feedback loop.  Explore this topic and using writing, diagrams, charts, graphs, and/or maps explain how the feedback loop works.  Note whether this is a positive or negative feedback loop.  Are there any other climate feedback loops you have discovered in your research?

Reflectivity and Albedo

Reflectivity is simply the concept that some surfaces reflect more light while others absorb more light.  Albedo is the measure of the reflectivity of a surface, measuring the percentage of solar radiation reflected and absorbed.  Something with high albedo means it reflects a majority of the light that hits it.

Urban environments have very low albedos because of the amount of tarmac and buildings.  This causes what is known as an urban heat island, where urban areas experience warmer temperatures than the rural areas surrounding them.
Souce: EPA
Different surface types on Earth have differing albedos.


Source: CoCoRaHS
Ice and snow have high albedos and therefore reflect a large amount of light and heat energy from the sun.  When we consider that, as stated in the previous post, seasonal snow covers up to 33% of Earth's surface and ice sheets and glaciers cover an additional 10% of Earth's surface, we can conclude that these surfaces help the Earth reflect a great amount of solar radiation back into space. This prevents the Earth from absorbing more solar radiation and helps keep Earth's surface cooler. Human activity can greatly alter the surface of the Earth, and therefore can greatly alter it's albedo.

What happens to Earth's albedo when, as we know from the previous post, surface ice cover starts decreasing?
