The New Jersey Department of Education has taken an important step in avoiding a climate disaster. Beginning in September 2022, every New Jersey student in Grades K-12 will be studying the causes and effects of climate change in their community, state, nation, and world. In Social Studies classes, students will be researching, debating, proposing, and implementing solutions to reduce their carbon foot print, propose strategies for a sustainable environment in their schools and community, propose solutions at the state and national level, and collaborate with students and professionals in other countries about global initiatives. The goal of changing behavior at this critical time is to educate students with an interdisciplinary model and approaches in all disciplines.
Bill Gates focuses on solutions to the impending climate crises regarding the harms of the 51,000,000,000 (billion) tons of greenhouse gases that 7,500,000,000 (billion) people contribute to every year! Although on the average this is 70 tons a day, the per person contribution is significantly higher in the United States, New Jersey, and some other countries. Europe has a plan to become the first continent to become carbon neutral in 30 years. (What is the EU’s Green Deal? And could Europe become the first climate-neutral continent? | World Economic Forum (weforum.org))
The first application in How to Avoid a Climate Disaster is with the metaphors that will help students in the elementary grades to understand the effects of global warming.
For example: Imagine a bathtub of water with the drain closed that is slowly filling up with water. What will eventually happen? What will be the damage to the room or house? Why is it not enough to slow the amount of water filling up the bathtub?
Imagine sitting in a car with the sun shining on the glass windows. What happens to the temperature inside the car? Will opening the window half an inch make the car safe for passengers? Why is the temperature of the earth increasing every year? What will be the result if it continues to increase?
These metaphors will help students understand that small changes in our behaviors are helpful but they are not likely to solve the problem for what is causing the earth’s temperature to continually increase. Teachers will find valuable resources for teaching young children how electricity and cars contribute to greenhouse gas emissions. (Page 55) For example, electricity contributes about 27% of greenhouse gases to our environment. For younger children, teachers need to help their students understand how much electricity (megawatts and kilowatts) one family contributes. The average home uses 28 kilowatt hours of electricity per day. For example, my electric bill stated that our home consumed 630 kilowatt hours over 28 days or 23 kilowatt hours per day.
Ask your students to identify everything in their apartment of home that uses electricity. Then compare kilowatts to a cup or glass of water that would be emptied into a sink or tub with the drain closed. Have your students explain the effects of increasing and decreasing the amount of electricity consumed. The more electricity used and the more people using electricity will generate additional greenhouse gases that will harm the environment.
Another important understanding for younger children is to understand that each item they identify as using electricity uses different amounts of energy. For example, a light bulb might use 40 watts but the hair dryer uses 1,500. The critical application for younger students is to understand that by reducing the amount of electricity consumed helps the environment. In this context, teachers should scaffold to a higher conceptual level by understanding the impacts of more people in the home, community, and world. Reducing greenhouse gases is very difficult which is why understanding that everything we do and everything we produce has a harmful effect on our planet.
The second application is the useful information to support middle school student debates on the solutions to reduce greenhouse gases at the local, state, and national levels.
Middle school students should understand how human activity is accelerating climate changes by warmer temperatures. The technology of renewable sources, (i.e., solar, wind, nuclear, geothermal) should also be familiar to most students. However, the cost, amount of space needed to produce energy for a city, and the durability of the equipment are important areas for student research, problem-solving, and debate.
In the United States we have replaced energy several times over the past century. Many homes have fire places but wood burns quickly and heat is lost through the chimney. Coal and oil were more efficient resources to heat homes. They were eventually replaced in many homes with natural or propane gas. In the 1950s and 1960s the government supported high-powered transmission lines for electricity and underground pipes for natural gas. In the 1970s we transitioned from leaded gasoline to a more expensive grade of unleaded fuel. Understanding the processes of continuity and change over time for how people live is critical to understanding the societal costs of inexpensive fossil fuels.
In Zurich, Switzerland there is a DAC (direct air capture) facility operated by Climeworks which can remove (or absorb) carbon from the atmosphere as it is released. The cost is $100 per ton. Since the world is currently producing 51 billion tons of harmful carbon emissions EACH year, the cost is $5.1 trillion. The United States has a per person carbon footprint of 15 tons per person. The cost would be $1,500 per person or $6,000 for a family of four. This would be the cost EACH YEAR and a very expensive solution.
There are interesting hypothetical scenarios in How to Avoid a Climate Disaster regarding a place near Seattle or a large city the size of Tokyo. In these scenarios, students will find enough information for them to ask probing questions or search for more research regarding the average number of days with sunlight or wind speeds, the impact of severe weather, the amount of space on land or in water to build an energy farm, the costs to transmit electricity over long distances, and how to store sufficient power for evenings and when energy supplies are less than what is demanded.
Another interesting topic for middle school students to debate or discuss is the impact of electric vehicles on home energy supplies. Students need to consider the impact of charging multiple vehicles per household and in a city with high-rise apartments. The book also provides basic information that should motivate students to research the technologies of fusion, batteries, and nuclear power. The ITER project in southern France will likely be operational within this decade. Is fusion the magical answer for our goal of zero carbon emissions? Teachers will find empirical evidence in this book regarding current technology and experiments which are essential when teaching students how to support their claims and arguments with evidence.
The third application is for high school students to determine proposals for reducing the one-third of greenhouse gas emissions that come from producing plastics, cement, and fertilizers.
The media focuses on emissions from the fossil fuels of vehicles and the generation of electric power. Two areas that may not be familiar to students are that 19 percent of global emissions come from the production and application of fertilizers and 31 percent from industrial production. The combination of these two areas represents about one-half of the 51 billion tons of greenhouse gas emissions currently contributing to the increase in temperature. When studying continuity and change over time, students visually see how communities and cities change over 100 years, 50 years, or less. For example:
When studying the impact of land use on climate, students should explore the environmental costs to society from the use of cement, steel, glass, generation of electricity, loss of forested land, waste, and traffic. How to Avoid a Climate Disaster provides an opportunity for classroom exploration, research, inquiry, collaboration, and solutions. The contribution of the social sciences to understanding the causes of greenhouse gas emissions, strategies for changing the way we currently are doing things, and analyzing the externality of societal costs is found in what students do best – asking questions, researching, debating private and public solutions, analyzing the costs and long-term benefits, and presenting information clearly and concisely in graphs, tables, maps, and images.
Examples of questions for collaboration, researching, and interviewing by students are:
- How are we producing automobiles?
- Is natural gas the most efficient method for cooking food and heating buildings?
- What are the societal costs for raising animals for food?
- How should we recycle food waste?
- How would a Green Premium be calculated in analyzing the costs and benefits over time?
- How significant are the societal costs of air-conditioning on a global scale?
Standard 6.3 for climate for high school students in New Jersey requires them to collaborate with other students on proposed solutions.
6.3.12.GeoGI.1: Collaborate with students from other countries to develop possible solutions to an issue of environmental justice, including climate change and water scarcity, and present those solutions to relevant national and international governmental and/or nongovernmental organizations.
The competitive advantage of Social Studies in learning about the biggest issue to impact our planet in history is with our ability to engage in problem solving, understanding perspectives from different cultures, historical lessons of strategies to address problems over time, the ability to analyze the economics of the problem and solutions, and to debate the effectiveness of public and private solutions. The Social Studies classroom, especially in grades 6-12, is a laboratory for analyzing the marginal costs and losses of incremental changes, preventative solutions, investments in research and development, and the cost of inaction.
“Climate science tells us why we need to deal with this problem but not how to deal with it. For that, we’ll need biology, chemistry, physics, political science, economics, and other sciences.” (Page 198)
One of the best chapters in How to Avoid a Climate Disaster is the one on government. The perspectives on the electrification or rural America, installing natural gas lines, building the interstate highway system, implementing the Clean Air Act or 1970, the Montreal Protocol of 1987, and the Human Genome Project provide empirical examples of what the government of the United States has accomplished in the 20th century. The lessons of innovation and the call to debate solutions for reaching the goal of zero carbon emissions are opportunities that should be integrated into the existing curriculum. The Sunshot Initiative sponsored by the U.S. Department of Energy to reduce the costs of solar energy is one example worth studying in Economics or U.S. History. Here are some examples:
- Will the steps taken to reduce carbon emissions in your community or average size city in New Jersey work in Tokyo with a population of 38 million, or Mexico City, New York, or Mumbai?
- Is the best strategy for reducing carbon emissions one that is implemented at the local or state level of government, through national or global commitments, or by incentives to private firms?
- Are there dangers in making immediate but small reductions by 2030 or will it be more effective to wait for new technologies from current research?
- If society delays implementing carbon emission reductions now, will the costs be significantly more expensive if implementation is postponed five or ten years?
- What are the most effective incentives to lower costs and reduce risks? (tax credits, subsidies, loan guarantees, carbon tax, cap and trade system, etc.)
- How important are the actions taken by citizens, consumers, and producers in taking the initiative in reducing carbon emissions?
- What lessons have we learned from the Covid-19 pandemic that apply to our response to impending warmer temperatures and rising sea levels from carbon emissions?
As teachers in New Jersey begin to implement the K-12 mandated curriculum standards on climate and environmental sustainability, they should consider an interdisciplinary model that includes learning in every grade focusing on causes, effects, and solutions at the local, state, national, and global levels. Students who are age five in Kindergarten in 2021 will be 34 in 2050. Teachers who are age 25 or 30 now will be 55-60 in 2050. The curriculum that is planned and implemented will have a measurable legacy in the foreseeable future. In 1921, a nuclear bomb, sending a man to the moon, CT images, Global Positioning Systems (GPS) were impossible to imagine but by the middle of the 20th century they were in development of considered possible. Social Studies teachers must look beyond what is predictable today and teach students for a world that may be in conflict and crisis or one that can be safer and better.
