Teaching about the role of human actions is supported by seven concepts:a. Climate information can be used to reduce vulnerabilities or enhance the resilience of communities and ecosystems affected by climate change. Continuing to improve scientific understanding of the climate system and the quality of reports to policy and decision-makers is crucial.
b. Reducing human vulnerability to the impacts of climate change depends not only upon our ability to understand climate science, but also upon our ability to integrate that knowledge into human society. Decisions that involve Earth's climate must be made with an understanding of the complex interconnections among the physical and biological components of the Earth system as well as the consequences of such decisions on social, economic, and cultural systems.
c. The impacts of climate change may affect the security of nations. Reduced availability of water, food, and land can lead to competition and conflict among humans, potentially resulting in large groups of climate refugees.
d. Humans may be able to mitigate climate change or lessen its severity by reducing greenhouse gas concentrations through processes that move carbon out of the atmosphere or reduce greenhouse gas emissions.
e. A combination of strategies is needed to reduce greenhouse gas emissions. The most immediate strategy is conservation of oil, gas, and coal, which we rely on as fuels for most of our transportation, heating, cooling, agriculture, and electricity. Short-term strategies involve switching from carbon-intensive to renewable energy sources, which also requires building new infrastructure for alternative energy sources. Long-term strategies involve innovative research and a fundamental change in the way humans use energy.
f. Humans can adapt to climate change by reducing their vulnerability to its impacts. Actions such as moving to higher ground to avoid rising sea levels, planting new crops that will thrive under new climate conditions, or using new building technologies represent adaptation strategies. Adaptation often requires financial investment in new or enhanced research, technology, and infrastructure.
g. Actions taken by individuals, communities, states, and countries all influence climate. Practices and policies followed in homes, schools, businesses, and governments can affect climate. Climate-related decisions made by one generation can provide opportunities as well as limit the range of possibilities open to the next generation. Steps toward reducing the impact of climate change may influence the present generation by providing other benefits such as improved public health infrastructure and sustainably built environments.
Humans cause climate change, and humans can address climate change too.
Climate change can be a tough topic to teach. But talking about the solutions can bring a hopeful message to the classroom and empower students. It's essential that students understand the types of actions we can take, and the scale at which these changes are necessary. Humans need to reduce emissions of heat-trapping gases, while also preparing for impacts, planning for resilient communities, and protecting the ecosystems that sustain us. Addressing climate change will be a monumental a challenge, and no doubt some of today's students will be instrumental in designing and implementing future solutions.
It is vital that students understand solutions
- Although human-caused climate change is a global problem, its root cause lies in the sum of our individual actions.
- Types of actions to reduce climate change can take many forms, such as emissions avoidance, land use changes, or sequestration of greenhouse gases.
- The scale of actions can range from an individual to a community, to a nation, or a grouping of nations.
- Climate and energy policies are currently being crafted by various nations and communities.
- All citizens, including students, can provide input into new policies; the resulting policies are likely to have an effect on all of us.
- Actions are not always driven by policy. Some corporations are taking actions to address climate change even without being required to do so.
- Actions can be spurred by policy, economic incentives, a sense of environmental or social responsibility, or a combination of each of these.
Some examples of mitigating climate change: The climate and energy challenges that society must address in the coming years and decades can be overwhelming for many learners. The scientific findings of global change research can be alarming and discouraging even for seasoned scientists. Many students, even before they fully master the science, will want to know what they can do to make a difference. Teachers are finding that weaving together science with solutions is an important strategy to avoid depressing their students.

Many students, even before they fully master the science, will want to know what they can do to make a difference. Teachers are finding that weaving together science with solutions is an important strategy to avoid depressing their students.
Solutions are frequently interdisciplinary and span science, engineering, economics, and policy. Examining the realities of integrating solutions into our society are potent ways to teach these topics. That said, educators should exercise care with policy discussions and avoid political debates that can distract from the main goal of mastering the content.
Ultimately, if students are facile in their understanding of solutions, they will be able to evaluate choices on the basis of multiple factors, and can weigh advantages and tradeoffs. This type of critical thinking is essential for making informed decisions and solving complex problems - skills that all students will need as engaged citizens.
Bringing these ideas into your classroom
A pedagogic technique that is particularly effective is to have students take a quantitative approach to discover the scale of the problem and thus the scale of potential solutions. For example, how many light bulbs would need to be changed in order to offset rising carbon emissions? Is it possible to plant enough trees to soak up excess CO2? (See activity Atmospheric Carbon: Can We Offset the Increase? ) Often the best way for students to reach an understanding is to engage them in a problem-solving activity that allows them to discover answers for themselves.
Teaching materials from the CLEAN collection
More than many other aspects of climate literacy, many of these activities span several grade levels
- There's a Thief in My Kitchen investigates energy use of different light bulbs. Students can pair that with a Carbon calculator activity, and then do basic calculations to measure the effect if every student in the country took similar actions.
- Plant for the Planet offers an upbeat example of a young student who rallies his community and other children to plant millions of trees to offset emissions.
- The EPA's guide to Technologies that Reduce Greenhouse Gases offers a student-friendly summary of many different forms of renewable energy.
- In the Renewable Energy Living Lab: Energy Priorities, students explore real data about renewable energy potential in their state using a mapping tool developed by National Renewable Energy Laboratory.
- The Green Revolution is a series of 10 short videos featuring scientists, research, and green technologies.
- There are several lesson plans that incorporate a renewable energy mapping tool from the National Renewable Energy Labs, called Renewable Energy Living Lab. These lessons evaluate feasibility, cost, and environmental impacts of installing renewable energy, and they are a way to bring engineering and design into the subject.
- The Stabilization Wedges Game and the related Carbon Wedges interactive are helpful for illustrating the scale of changes needed to accomplish significant emissions reduction.
- This Carbon Footprint and Carbon Calculator activities use two different versions of EPA's carbon calculator.
- The Energy Lab is a simulator that allows students to meet projected energy demand while also minimizing atmospheric CO2.
- Solutions to climate change are sometimes mis-characterized as something that is only relevant to "green" industries and people. Richard Alley's video illustrates the military's approach to the subject with The Pentagon and Climate Change and Khaki Goes Green.
- Four Generations of Green offers a vignette of a family dairy that infuses sustainable practices throughout their operation.
