In the Next Generation Science Standards (NGSS), climate change and the greenhouse effect are not treated as isolated topics. Instead, they are woven across multiple grade levels primarily within Earth and Space Sciences (ESS)—specifically under Earth's Systems (ESS2) and Earth and Human Activity (ESS3)—as well as connecting to life and physical sciences.

Rather than just memorizing facts, the standards require students to build models, analyze data, and evaluate human impacts.

1. Middle School (Grades 6–8)

At the middle school level, the focus shifts toward recognizing patterns in Earth’s history, understanding the baseline mechanics of weather versus climate, and investigating the specific drivers of recent global temperature increases.

• MS-ESS2-6: Weather and Climate

  
  

  • What students do: Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.

• MS-ESS3-5: Global Climate Change

  
  

  • What students do: Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.

  • Core Idea Connection (ESS3.D): Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth's mean surface temperature. Students look at historical data regarding carbon dioxide emissions, solar output, and volcanic activity to evaluate what drives global temperature trends.

2. High School (Grades 9–12)

At the high school level, expectations become much more rigorous, requiring quantitative modeling, complex feedback loops, and evaluating mitigation strategies.

• HS-ESS2-4: Energy Flow and Climate

  
  

  • What students do: Use a model to describe how variations in the flow of energy into and out of Earth’s systems result in changes in climate.

  • Core Idea Connection (ESS2.D): Changes in the atmosphere due to human activity have increased carbon dioxide concentrations, directly altering the greenhouse effect and trapping more thermal energy.

• HS-ESS2-2 & HS-ESS2-6: Feedbacks and Biogeochemical Cycles

  
  

  • What students do: Analyze geoscience data to show how a change to one Earth system (like melting ice caps lowering surface reflectivity) creates feedbacks that alter other systems. They also study how carbon cycles through the atmosphere, ocean, soil, and biosphere.

• HS-ESS3-5 & HS-ESS3-6: Modeling and Forecasting Climate Impacts

  
  

  • What students do: Analyze data using computational models to make valid and reliable forecasts of the current rate of global or regional climate change.

  • Core Idea Connection (ESS3.D): High school standards emphasize that future climate projections heavily depend on human choices regarding greenhouse gas emissions and how those gases are absorbed by natural sinks like the oceans and forests.

3. Crosscutting Concepts & Science Practices

The NGSS framework deliberately anchors climate change discussions around specific crosscutting concepts:

• Stability and Change: Students examine how small shifts in atmospheric composition can destabilize a previously balanced planetary energy budget.

• Cause and Effect: Tracing the mechanistic link from human industrial activities $\rightarrow$ increased greenhouse gas concentrations $\rightarrow$ altered radiation trapping $\rightarrow$ rising global temperatures and shifting weather patterns.

• Systems and System Models: Using computer simulations, graphs (like the Keeling Curve), and physical models to visualize energy flows that cannot be easily observed directly.
