This simulation allows the user to project CO2 sources and sinks by adjusting the points on a graph and then running the simulation to see projections for the impact on atmospheric CO2 and global temperatures.

Students investigate how much greenhouse gas (carbon dioxide and methane) their family releases into the atmosphere each year and relate it to climate change. To address this, students use the Environmental Protection Agency Personal Emissions Calculator to estimate their family's greenhouse gas emissions and to think about how their family could reduce those emissions.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

This static graph of changes in CO2 concentrations goes back 400,000 years, showing the dramatic spike in recent years.

This video describes how Colorado has planned for and uses clean energy resources to reduce its carbon footprint.

This video reviews the benefits and drawbacks associated with growing corn to make ethanol.

A simple three-part diagram from UNEP GRID Vital Water Graphics showing what the impact of global warming will be on projected coastlines and populated areas of Bangladesh with a 1 and 1.5 m sea level rise relative to the current coastline.

These five short videos are an introduction to the pros and cons of energy issues, including cost, choices, efficiency, environmental impact, and scale. The videos are segments of a feature documentary entitled, Switch: Discover the Future of Energy.

This slideshow lays out a photo story with short descriptions of how city buildings all over the world are taking climate change and rising sea level seriously, designing structures that can react to unforeseen changes. As sea levels continue to rise, architects design ways to live with the rising water.

This lab exercise is designed to provide a basic understanding of a real-world scientific investigation. Learners are introduced to the concept of tropospheric ozone as an air pollutant due to human activities and burning of fossil fuel energy. The activity uses, analyzes, and visualizes data to investigate this air pollution and climate change problem, determines the season in which it commonly occurs, and communicates the analysis to others in a standard scientific format.
