Introduction

I feel strongly that young people should be given the chance to understand climate change as soon as possible. This will help them deal not only with the immediate challenges facing us, but the longer term ones. It will, for example, assist them in making career choices, for some businesses will expand greatly while others will decline. It will also assist them with consumer choices, because as their understanding of climate change grows, individuals will develop new attitudes about what is appropriate and moral. Young people may even grow up in a world where the relationships between nations will shift. This may occur in part because the tropical rainforests offer a great way of drawing carbon pollution from the air, so the poorest farmers on our planet may become crucial partners to the wealthy nations as they seek to stabilise their climate.

One of the most exciting, and immediately relevant, opportunities for young people concerns the new technologies for generating electricity, and providing transport without creating greenhouse gas pollution. In coming decades, these vital tools for stabilising our climate will be develop and brought to market by today’s school children. And tomorrow’s economists will struggle with issues that are new to us. An entire new global market – a trade in will be established, which will have broad implications for many aspects of our lives.

For all of these reasons, I believe that the study of climate change is relevant to a great many of the subjects our children undertake, and that by increasing their understanding of the issue they will see the relevance of such disciplines anew. Indeed, as their understanding of the issue develops I believe that they will start seeing the world in a new way, a way that most of us have not possessed. That may seem like a large claim, but as we move to address climate change, so many aspects of our world will alter that it will be little short of a revolution.

“Get the facts on the world’s hottest topic”

Begin by opening your learning journal for this activity.

A recent exhibition on climate change at the Birch Aquarium at the Scripps Institution of Oceanography in San Diego ,USA, used the headline: “Feeling the Heat: The Climate Challenge – Get the facts on the world’s hottest topic” to attract visitors to study the exhibition panels.

This activity is designed to provide the facts on climate change science as they are currently understood by the world’s best scientists.

Consider the following statement about climate change from the Nautilus Institute on Security and Sustainability:

Earth is facing a climate catastrophe caused by human action. Scientifically, there is no longer any doubt that pollutants from the combustion of fossil fuels and other human activities are accumulating in the atmosphere, trapping radiation, and raising temperatures. There remains some uncertainty about the precise timing and magnitude of the warming, and about the impacts that will result from it, but this is due as much to uncertainties about how we, as humans, respond to the problem as to scientific uncertainties.

Many types of impact are predictable and some are likely already under way: rising temperatures, changes in rainfall levels and seasonality; increased incidence of extreme weather events such as droughts, floods and hurricanes; sea level rise; the melting of polar ice and glaciers. The ecological and human impacts resulting from these changes are expected to include desertification, loss of tropical forests and coral reefs, declines in agricultural productivity, extinction of species, water shortages, growing casualties from natural disasters, and the spread of tropical diseases.

Whether the scale of these impacts brings just a further decline in environmental quality and social well-being or leads to a truly catastrophic collapse that leads to starvation, massive migration, and resource wars, will depend on human action during the next several decades, and on the possibility of unanticipated response in the climate system to increasing temperatures and greenhouse gas concentrations.

Q1: Researchers in the Nautilus Institute tried hard in this statement to distinguish between certain and uncertain scientific claims about climate change. Use your learning journal to identify the claims that science is certain about.

Check the accuracy of your answer by referring to the lists of certainties and uncertainties about climate change identified in the 2007 report of the Intergovernmental Panel on Climate Change, the United Nations’ scientific body researching climate change.

Teaching about Certainty and Uncertainty

A concern of many teachers on matters of climate change is a lack of confidence – both in having the knowledge they need to plan appropriate learning experiences for students and in being able to distinguish between scientific certainties and unproven claims. This is especially the case when so much climate science is based upon the interpretation of trends and complex modeling of the climate system. Some teaches believe that student respect rests on their projecting an image of being “all knowing”. When faced with the task of teaching a topic as important but complex as climate change, such feelings can be a real constraint.

A key to overcoming this problem is to be found in the certain knowledge that on any subject there is always more information than any one person can grasp. Climate change is a subject on which even specialists have much to learn. However, it is also a subject upon which much information is readily available as seen by the long list of books and internet sites in the references section of this module.

Climate change is also a subject upon which everyone has some knowledge and can contribute to a total understanding. We can help ourselves and our students by establishing mutual respect and a setting for mutual learning by discussing the problems of scientific certainty and uncertainty openly. Such a setting is also an ideal place for assessing the importance of taking precautionary action under conditions of uncertainty.

Activity 4 in Module 4 focused upon the objectives of Education for Sustainable Development. Seven objectives were analysed there. The seventh was “Appreciation of uncertainty and precaution”. You can analyse the educational advantages of working with students towards this objective in this diamond-ranking exercise.

Q2: Identify five other subjects you might teach in Education for Sustainable Development where there are also opportunities to achieve the educational benefits of working with students about uncertainty and precaution. A quick review of other modules in the Contemporary Issues section of Teaching and Learning for a Sustainable Future might help here.

Climate change FAQ

Begin by opening your learning journal for this activity.

A lot of different terms are used in discussions about climate change. Some of these include:

  • Global warming
  • Greenhouse effect
  • Natural Greenhouse Effect
  • Enhanced Greenhouse Effect

In fact, in his book and film, An Inconvenient Truth, former US Vice President Al Gore argued that the situation is so severe that terms such as these and climate change are so neutral that they do not encapsulate the urgency of the “planetary emergency” we are facing. Mr Gore suggested that we use the term, “Climate Crisis”.

A simple overview

Whatever terms you prefer to use, they all refer to the fact that carbon dioxide and other gases in Earth’s atmosphere act like a greenhouse moderating the temperatures we experience. These warm the surface of the planet naturally by trapping solar heat in the atmosphere. This is a good thing because it keeps our planet habitable. However, by burning fossil fuels such as coal, gas and oil and clearing forests we have dramatically increased the amount of carbon dioxide in Earth’s atmosphere and temperatures are rising. This is called the “enhanced Greenhouse Effect”.

Greenhouse Effect         Enhanced Greenhouse Effect

Source: What is Climate Change?

A colourless and odourless gas formed from one carbon and two oxygen atoms, CO₂ makes up around three parts per 10,000, or 0.03%, of Earth’s atmosphere. This is a very small amount but it plays a critical role in maintaining the atmospheric balance necessary to all life. By contrast, the atmosphere of “dead planets” such as Venus and Mars is made up mostly of CO₂.

The CO₂ produced by plants has been central in keeping Earth’s surface temperature at an average 14°C for the past 10,000 years, which is very habitable for the plants, animals and human activities we know today. This is called the “natural Greenhouse Effect”

Much of the rock, soil, animal, plant and water life on Earth is made up of carbon, very much of it stored for millions of years under the ground or ocean in fossilized form from decayed animal and plant matter. When this is extracted and burned – as a fossil fuel – such as oil, gas and coal, carbon escapes into the atmosphere where it combines with oxygen to form CO₂. This means that CO₂ is a waste product – or pollution – every time we burn fossil fuels to make gas or electricity for heating, light and cooking or use petrol to drive a car – and it stays in the atmosphere for about 100 years.

As a result, the proportion of CO₂ in the atmosphere is rapidly increasing, causing Earth to warm. This is causing average temperatures to rise, which is resulting in more frequent extreme weather events, long-term droughts, melting polar ice caps and glaciers and rising sea-levels. The relationship between rising temperatures and sea-levels over the past 100 plus years may be seen in the following diagrams.

         

Source: Kirby, A. (2008) Climate in Peril, UNEP/GRID-Arendal and SMI Books, pp. 8-9.

Earth’s surface temperatures rose by about 0.6°C over the 20th century. The most recent predictions from the Intergovernmental Panel on Climate Change are that the average global surface temperature will continue to rise – and could potentially reach 6.4°C above 1990 levels by 2100 unless immediate action is taken. At that temperature human society as we understand it would no longer exist.

From concentrations of just 0.028% CO₂ in the atmosphere in pre-industrial 1750, CO₂ concentrations have risen to 0.043% today. Until recently it was believed stabilising CO₂ in the atmosphere at around 0.055% by 2035 could limit warming by 2°C. However, now 3°C is more likely, causing major impacts on human settlements, coral reefs, rain forests and the polar ice-caps. Urgent international action is needed to limit temperature rises to 2°C, and that means controlling CO₂ levels to 0.045%. This could be a reality by 2020 if governments are able to agree on cooperative national and international action.

  11. Is the current climate change unusual compared to earlier changes in Earth’s history?
  12. Are the increases in atmospheric carbon dioxide and other greenhouse gases during the industrial era caused by human activities?
  13. How reliable are the models used to make projections of future climate change?
  14. Can individual extreme events be explained by greenhouse warming?
  15. Can the warming of the 20th century be explained by natural variability?
  16. Are extreme events, like heat waves, droughts or floods, expected to change as the Earth’s climate changes?
  17. How likely are major or abrupt climate changes, such as loss of ice sheets or changes in global ocean circulation?
  18. If emissions of greenhouse gases are reduced, how quickly do their concentrations in the atmosphere de¬crease?
  19. Do projected changes in climate vary from region to region?

Impacts of climate change

Begin by opening your learning journal for this activity.

The 2007 report of the Intergovernmental Panel on Climate Change (IPCC) left no doubt that global warming is occurring and that climate change is human-induced. The IPCC concluded that “warming of the climate system is unequivocal” and, for the first time, stated that it was 90% certain that it was caused by the effects of human activities on Earth since the beginning of the Industrial Revolution in the 1700s in Europe and later in North America. And it is increasingly clear that these rising temperatures are having significant impacts on the world already and that many more are likely.

Read about the impacts climate change is already having in different countries around the world.

A map launched at the Science Museum in London has been developed using the latest peer-reviewed science from the British Met Office and other leading impact scientists. It shows that the land will heat up more quickly than the sea, and high latitudes, particularly the Arctic, will have larger temperature increases.

Examine the impacts of climate change predicted for different continental regions of the world:

Q3: How severely will climate change affect your country or region?

These many examples show that there are two levels of impacts from climate change.

The first level include the impacts of rising temperatures on the physical environment, such as:

  • Glaciers melting faster than predicted
  • The flow of ice from glaciers in Greenland has more than doubled over the past decade.
  • The Arctic ice caps are meeting so fast that a sea passage between north America and Russia has almost formed in recent summer
  • Global sea levels rises, especially in low lying river deltas and small island states
  • The number of Category 4 and 5 hurricanes has almost doubled in the last 30 years
  • Nearly 300 species of plants and animals are moving closer to the poles
  • Heat waves are becoming more frequent and more intense
  • Droughts and wildfires are occurring more often.

However, because we depend upon the physical environment for all the resources we need – water, food, clothing, shelter, manufactured goods, transport, energy, jobs, recreation, etc. – these primary impacts cascade into a second level where they impact on the resources we need such as:

  • Water – including drought, water quality, water supplies
  • Food – including cropping and livestock sectors
  • Ecosystems – including national reserves, species diversity, and natural and plantation forests
  • Coasts – including fisheries, marine life, coastal infrastructure
  • Health – including heat stress, vector borne diseases
  • Settlements – including infrastructure, local government, planning, transport, energy, emergency services

The 2007 IPCC report summarized the extent of these impacts under conditions of 1, 2, 3, 4 and 5°C temperature increases.

Impacts in the Amazon

The long-term impacts of climate change – such as those in the table – can seem abstract unless they are grounded in case studies of real places and people. Here we take the Amazon region as an example.

The Amazon rainforest is a critical influence on South American climate and one of the world’s most important carbon banks. It covers almost as much land as China, Australia or the United States, and is home to 20% of all the world’s plant and animal species. The rainforest also plays a crucial role in the water cycle of South America and pumps oxygen into the atmosphere, earning it the nickname, the “Lungs of the World”.

Climate scientists predict a significant dieback of the Amazon rainforest by 2050 and predict that the area will have larger losses of soil and plant carbon than of any other place on Earth by the end of the 21st century. This shrinking of the Amazon rainforest is a major reason why scientists predict the vegetation of the Amazon rainforest will shift from being a “carbon sink” to a major source of carbon by 2050.

Read about the predicted impacts of small temperature increases on the rain forests of the Amazon.

Read about the impacts of climate change on the strategies that the Shipibo people of the Peruvian Amazon traditionally use to cope with the severe floods of their tributary of the Amazon.

Q4: What advice would you give the governments of the Amazon region about how to minimize the impacts of increased temperatures on the rainforest?

Q5: What advice would you give the Shipibo people about adapting to the changed climatic conditions along the River?

Impacts in your community

Q6: In what ways is your community experiencing the impacts of climate change?

Q7: Which of the nine impacts is the most likely to affect your local community? Why?

Q8: Which of the nine impacts is least likely to affect your local community? Why?

Q9: Who do you think will be most affected by this impact? Why?

Q10: What options are being explored in your community to try to adapt to these environmental changes?

Climate change is an ethical issue

Begin by opening your learning journal for this activity.



[Click image for full size]

When we were looking at the impacts of climate change in Activity 3, we saw that the long-term impacts of climate change can seem abstract unless they are grounded in case studies of real places and people. So, we then conducted a case study of the impacts in the Amazon region as an example. This helped us to see the details, especially when we then examined climate change impacts in our local communities.

This helped us to see that climate change is not just a scientific issue – or a political one for governments to solve. Climate change is an ethical issue too because climate disasters hit the poorest people of the world the most. This activity examines the arguments that have been made for this by three international bodies: the Commonwealth Foundation, the World Bank and the Association of Small Island States.

The Commonwealth Foundation

In a speech to the 2007 Commonwealth Youth Forum in Kampala, the Director of the Commonwealth Foundation, Mark Collins said that climate change was the most important issue facing the world. In fact, he said, “If the Millennium Development Goals were being written today, tackling climate change would be top of the list”.

We are now past the halfway stage towards the 2015 target for the Millennium Development Goals (MDGs) but performance is falling behind, at least partly because environmental sustainability is not being addressed adequately. Unless we can control deforestation, protect biodiversity, ensure water supplies and address the [carbon] pollution that causes climate change, poverty will always stalk the world.

These should not be seen as narrowly-defined environmental problems. Climate change in particular is an economic and humanitarian problem.

Source: Collins, M. (2008) Climate Change: A Priority Issue for the Commonwealth.

Q11. The Commonwealth Foundation identified two ethical arguments about climate change:

  • Climate change is a major cause of poverty
  • The cost of addressing climate change will slow progress towards Millennium Development Goals in many poorer countries.

Identify passages in the text that relate to these concerns.

The World Bank

The World Bank argues that the development implications of climate change for the poorest countries in the world are very significant. This is because developing countries are more vulnerable to the increased impacts of extreme weather events (i.e., floods, droughts and storms) and other changes than rich countries. For example, climate change is expected to (among other things):

  • increase climate variability and hurt agricultural productivity throughout the tropics and sub-tropics (threatening food security)
  • further decrease water quantity and quality in most arid and semi-arid regions (where poor communities depend on rainfall for their crops and drinking water)
  • increase the incidence of malaria, dengue fever and other vector-borne diseases in the tropics and sub-tropics (where health services are already weak death tolls would rise)
  • harm ecological systems and their biodiversity (that will provide fewer services, livelihoods and income possibilities to communities and societies)
  • raise sea levels and displace tens of millions of people in low-lying areas, such as the Ganges, Mekong, Red and Nile river deltas (threatening the very existence of many cities and even some small island states.

Responses to climate change in developed countries may also increase prices for energy, food, and other commodities, making these items more expensive for developing countries. In some cases, the adoption of carbon neutral technologies may need to be accelerated despite the higher commercial costs and risks.

The emerging and yet incomplete cost estimates of additional investments needed in developing countries are likely to cost hundreds of billions of dollars a year for several decades. Needing to find such resources may make achieving the Millennium Development Goals even more difficult in many developing countries.

Thus, many hard-earned development gains could be lost because of climate change, leaving more people in poverty and possibly pushing still more there also. The poorest communities and countries have contributed least to the problem but will be affected worst.

Q12. Identify five ethical issues in the World Bank’s concerns about climate change and development. Quote passages in the text to support these concerns.

Association of Small Island States

The ethical basis of climate change is central to the international advocacy work of the Association of Small Island States (AOSIS). AOSIS is a coalition of small island and low-lying coastal countries that share similar development challenges and concerns about the environment, especially their vulnerability to climate change. AOSIS has a membership of 43 States and observers, drawn from all oceans and regions of the world: Africa, Caribbean, Indian Ocean, Mediterranean, Pacific and South China Sea. Thirty-seven are members of the United Nations and make up 20% of the UN’s membership. Together, they are close to 28% of all the developing countries in the world and are home to five percent of the world’s population.

AOSIS would like to be seen as the conscience of the international community on climate policy because of what it sees as the truth and justness of its cause. AOSIS believes that island countries should have a central role in international climate negotiations because they face the greatest risks from climate change. Otherwise, it claims, AOSIS countries face “destruction without representation”. The principle of representation proportionate to risk is one that AOSIS.

According to the Ambassador for St. Lucia in the Caribbean,

If even a decade passes before beginning the process of reducing greenhouse gas emissions, we will be forced either to make far more drastic cuts later, or to incur unacceptable damage to the global climate system. If we wait for the proof, the proof will kill us.

Q16: What are the major ethical issues about climate change in your country? To what extent are they similar or different from the ones identified in this activity? Why?

Responding to the challenge of climate change

Begin by opening your learning journal for this activity.

Using TLSF CDRom version?

UNEP has kindly made Kicking the Habit available here for teachers studying Teaching and Learning for a Sustainable Future using the CDRom version.

The threats posed by climate change make it a matter of extreme urgency that we take action, immediately to limit the effects and, in the longer term, to adapt to the changes that are sure to come. This is perhaps the defining challenge of our age but it human will-power, decisions and action – as individuals, businesses, cities and governments – that will determine just how serious the problem will become.

The United Nations Environment Programme (UNEP) has prepared a guide for responding to the challenges of climate change called Kick the Habit: A UN Guide to Climate Neutrality. It is available as a PDF download or an interactive e-book. There is also a pre-prepared Powerpoint presentation. Together, these provide a rich guide to strategies for advancing the transition to a carbon neutral world..

The two major strategies for responding to the challenge of climate change are called mitigation and adaptation. These are distinct – but complementary – strategies, and both are needed for an effective response to climate change.

Mitigation

Climate mitigation involves actions that seek to permanently eliminate or reduce the long-term risk and hazards of climate change to human life, ecosystems or property. The International Panel on Climate Change (IPCC) defines mitigation as:

An anthropogenic (human) intervention to reduce the sources or enhance the sinks of greenhouse gases.

Mitigation tackles the causes of climate change by reducing the amount of CO₂ emitted into the atmosphere. That is, it refers to all the actions we can take to reduce the burning of fossil fuels – and includes strategies for reducing energy usage, increasing energy efficiency replacing fossil fuels by other energy sources and trapping CO₂ and other greenhouse gases under the ground, in the soil or in plants.

This table is a list of strategies for achieving mitigation goals that are available today and expected to be available by 2030.

Mitigation

[Click for full size]

See the IPCC page on climate change mitigation for more details.

Adaptation

Adaptation refers to the ability of a system to adjust to climate change in order to moderate potential damage, to cope with the consequences, or to take advantage of opportunities. The IPCC defines adaptation as:

…the adjustment in natural or human systems to a new or changing environment. Adaptation to climate change refers to adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities.

Climate adaptation tackles the effects of climate change by minimising its impacts. That is, it refers to all the actions we can take to prevent or offset damage to ecosystems, agriculture, coastal areas, urban infrastructure and human health.

Some examples of adaptation strategies include:

  • Water: increased rainwater harvesting, water storage and conservation, water re-use, desalination, greater efficiency in water use and irrigation
  • Agriculture: altering planting dates and crop varieties, relocating crops, better land management (for example erosion control and soil protection by planting trees)
  • Infrastructure: relocating people, building seawalls and storm surge barriers, reinforcing dunes, creating marshes and wetlands as buffers against sea level rise and floods
  • Human health: action plans to cope with threats from extreme heat, emergency medical services, better climate-sensitive disease surveillance and control, safe water and improved sanitation
  • Tourism: diversifying attractions and revenues, moving ski slopes to higher altitudes, artificial snow-making
  • Transport: realigning and relocating routes, designing roads, railways and other transport equipment to cope with warming and drainage
  • Energy: strengthening overhead transmission and distribution networks, putting some cabling underground, energy efficiency and renewable energy, reduced dependence on single energy sources.

See the IPCC page on climate change adaptation.

Q17: Mitigation seeks to reduce the amount of carbon in the atmosphere but adaptation seeks to help us reduce the effects of carbon in the atmosphere. Which approach do you think is the most important? Why?

Complementary approaches

Neither mitigation (reducing the potential impacts by slowing down the process itself) nor adaptation to climate change (reducing the potential impacts by changing the circumstances so that they strike less hard) alone can avoid all climate change impacts. However, together they can significantly reduce the risks of climate change.

In general the more mitigation we can achieve, the less will be the impacts to which we will have to adapt, and the less the risks for which we will have to try and prepare. Conversely, the greater the degree of preparatory adaptation we make, the less may be the impacts associated with any given degree of climate change. Thus, climate mitigation and adaptation should not be seen as alternatives to each other, as they are not discrete activities but rather a combined set of actions in an overall strategy to reduce greenhouse gas emissions.

The urgency of action

Stern Report

In 2006, the UK government published the Stern Report on the economics of climate change. Named after the prime author, Nicolas Stern (now Lord Stern) who worked for the Treasury, the report is the world’s biggest ever economic evaluation of climate change.

The Stern Report found that the cost of global warming and its effects would be over US$9 trillion – a bill greater than the combined cost of the two World Wars and the Great Depression – if immediate action was not taken. Even if the world stopped all carbon pollution today, much of this cost would be unavoidable because the long term effects of carbon already in the atmosphere means continued climate change for another 30 years, with sea levels continuing to rise for a century.

The actions recommended include:

  • Global emissions must fall by at least 50% relative to 1990 levels by 2050, in order to limit the grave risks associated with severe climate change. This will require concerted collaborative action with little scope for any large group of people to depart significantly the target
  • Developed countries – who produced the greenhouse gases already in the atmosphere over the past century – must take on immediate and binding national targets of 20% to 40% emission reduction by 2020, and to commit to reductions of at least 80% by 2050
  • Successful demonstration by developed countries that they can deliver credible reductions by 2020 – without threatening growth – will drive the design of mechanisms and institutions to transfer funds and technologies to developing countries
  • Subject to this, a formal expectation that developing countries would also be expected to take on binding national targets of their own 20% emissions reduction by 2020
  • Fast growing middle income developing countries with higher incomes must take immediate action in order to stabilise and reverse emissions growth
  • A commitment by all countries, regardless of targets, to develop the institutions, data and monitoring capabilities, and policies to avoid high-GHG infrastructural lock-in.

Q18: Summarise the actions that Lord Stern believed must be taken by:

  • Developed countries
  • Developing countries
  • Middle income developing countries
  • All countries

Significantly, the Stern report predicted that the world would only need to spend one per cent of global GDP, around US$500 billion, to achieve these goals – or roughly what is spent worldwide on advertising each year, and half of what the World Bank estimates would be the cost of a global flu pandemic.

Q19: Compare the cost of effective international action on climate change to the cost of fixing other global problems.

Taking action

Begin by opening your learning journal for this activity.

There is little doubt that the need for action to address climate change is very urgent. Governments, business and industry, communities, households and individuals all have important roles to play.

An enormous number of books, websites and brochures from governments and environmental groups telling us what actions we can take to avoid climate change. For example, the end of the book and movie of Al Gore’s, An Inconvenient Truth, provides a list of actions for people to take:

10 Things to Do
[Click for full size PDF]

  1. Change a light
  2. Drive less
  3. Recycle more
  4. Check your tires
  5. Use less hot water
  6. Avoid products with a lot of packaging
  7. Adjust your thermostat
  8. Plant a tree
  9. Turn off electronic devices
  10. Spread the word

Q20: Which of these actions would/do you find (i) relatively easy and (ii) more difficult to take? Why?

Q21: It has been argued that the list of actions recommended in An Inconvenient Truth are too individualistic and best suited to people who live in rich developed countries. Do you agree? Why?

Q22: If it is true that the actions are too individualistic and best suited to people who live in rich developed countries, why might Al Gore still have developed such a list?

An Internet search for the terms <“climate change” + “what you can do”> on 22 March 2009 revealed 16,100 sites in Australia alone and 261,000 worldwide. When “what you can do” in this search was changed to “what governments can do”, Google identified 146 and 2,340 sites, respectively. Substituting “what companies can do” and “what corporations can do” identified a total of only 12 sites in Australia and 1,405 sites worldwide.

Q23: Conduct a similar Internet search for your country and identify how many sites are identified.

Q24: Compare the results from the Internet search in your country with the results of the search in Australia. Why might there be any similarities or differences?

Q25: Why do you think that there are more websites for what individuals can do about climate change than what companies and governments can do?

Recognising the importance of what everyone – individuals, families, communities, governments and businesses – can do about climate change led the Worldwatch Institute to identify ten key strategies for mitigating and adapting to climate change. The first of these was lifestyle changes by individuals but the other nine emphasise roles for all sectors of society. The ten strategies are:

Changing Lifestyles
The assumption that the “good life” requires ever more individual consumption, more meat-eating, ever larger homes and vehicles, and disposable everything will need to fade. A spirit of shared and equitable material sacrifice can replace it – with no loss of the things that really matters, such as active good health, strong communities, and time with family. See the module on Sustainable Communities.
Thinking Long-term
At the core of the climate problem is the likelihood that future generations will pay with a deteriorating global environment for the refusal of current generations to live in balance with the atmosphere. Visionary leaders will need to marshal the public to take responsibility for the impacts of today’s behavior on the future and to act accordingly. Sustainability means learning how to think in terms of forever.
Innovation
The emissions shift will require technologies that break the carbon link to energy consumption with as little sacrifice of price and convenience as possible. A range of renewable technologies can produce electricity and meet heating and cooling needs. Such technologies include buildings that produce more energy than they consume and “smart grids” that use information technology to match renewably produced electricity precisely to demand.
Population
Rarely addressed in the context of climate change, future population trends could make the difference between success and failure in the long-term balance of human activities, atmosphere, and climate. The world’s population is likely to stop growing and then gradually decline for a period when women gain the full capacity to decide for themselves whether and when to have children. See the module on Population and Development.
Healing Land
Managed for the task, the Earth’s soil and vegetation can remove billions of tons of carbon from the atmosphere. Agricultural landscapes can accomplish this while improving food and fiber production and minimizing the need for artificial fertilizer and fossil-fuel-driven tilling and raising farmer incomes. See the module on Sustainable Agriculture.
Strong Institutions
The global nature of climate change demands international cooperation and sound governance. The strength and effectiveness of the United Nations, multilateral banks, and major national governments are essential to addressing global climate change. These institutions require strong public support for their critical work.
The Equity Imperative
No climate agreement will succeed without support from those countries that have so far contributed little to human-induced climate change, have low per-capita emissions, and stand to face the biggest challenges in adapting to the coming changes. Agreements and strategies that are fair to developing and industrialized countries alike are essential.
Economic Stability
Addressing climate change will demand attention to costs and the promise of improving rather than undermining long-term economic prospects. A climate agreement will have to operate effectively during anemic as well as booming economic periods, facing squarely the challenges of poverty and unemployment while continually reducing emissions of carbon dioxide and other greenhouse gases.
Political Stability
A world beset by conflict and terrorism is far less likely to prevent dangerous climate disruption than one at peace. Security and climate must be addressed simultaneously. Negotiating an effective and fair climate agreement offers countries a needed opportunity to practice peace and re-frame international relations along cooperative rather than competitive lines.
Mobilizing for Change
The way to deal with climate change we are causing is to see the opportunity for a new global economy and new ways of living in the effort to bring net greenhouse gas emissions to an end. There is no guarantee such a transition will be easy – or even possible. However, local and global movements to make the effort are needed now, and could yield new jobs, new opportunities for peace, and global cooperation beyond what humanity has ever achieved.

Q26: Categorise the ten strategies into their relevance for individuals, families, communities, governments and businesses.

Q27: Identify three of these strategies that you would be able to integrate into your teaching about climate change and other sustainable development topics. Briefly explain how.

Reflection

Begin by opening your learning journal for this activity.

Completing the module: Look back through the activities and tasks to check that you have done them all and to change any that you think you can improve now that you have come to the end of the module.

Read UNESCO’s Policy Dialogue on Climate Change and ESD. You will use this document to reflect on the issues of education and climate change that you have studied in this module.

Q28: What does UNESCO identify as the four implications for education about climate change?

Q29: To what extent do you feel comfortable about being able to teach towards the eight themes identified by UNESCO? These are:

  • clear distinctions between different scientific concepts and processes associated with climate change;
  • knowledge of, and abilities to distinguish between, certainties, uncertainties, projections and risks associated with climate change;
  • knowledge of the history and interrelated causes of climate change (which include technical, scientific, ecological and social dimensions; economic dimensions; and political dimensions);
  • knowledge of mitigation and adaptation practices that can contribute to wider social transformation towards sustainability, including abilities to participate in such practices;
  • knowledge of consequences and what is being learned about mitigation and adaptation to climate change;
  • good understanding of the time-space dynamics of climate change, including the delayed consequences that current greenhouse gas emissions hold in store for the quality of life, security and development options of future generations;
  • understanding of different interests that shape different responses to climate change (e.g. business interests, consumer interests, farmers’ interests, political interests, future generations’ interests, etc.) and abilities to critically judge the validity of these interests in relation to the public good; and
  • critical media literacy to address the causes of overconsumption and develop capacity to make better lifestyle choices and to participate in climate change solutions.

Q30: UNESCO suggests that climate change education should be (i) transformative and (ii) practice and solution-centred. Identify the modules in Teaching and Learning for a Sustainable Future that would provide advice on these two aspects of teaching and learning.

UNESCO suggests that schools could conduct a policy dialogue with different stakeholders on various questions about education and climate change. This could a dialogue at the national level of education and/or climate change policy – or it could be at the local school level.

Q31: Identify the stakeholder groups you would invite to a policy dialogue on climate change and education in your school community? What goal or outcome would you like from the discussion of each question?
