This animated map shows prevailing surface wind direction and strength across the United States.

This animated visualization represents a time history of atmospheric carbon dioxide in parts per million (ppm) from 1979 to 2011, and then back in time to 800,000 years before the present.

A colorful graphic that depicts the risks to the environment from different degrees of temperature rise. This graphic addresses how risks change as global mean temperature increases.

C-Learn is a simplified version of the C-ROADS simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.

Key figure from the 2007 Intergovernmental Panel on Climate Change (IPCC) report that shows changes in global average surface temperature, global average sea level, and Northern Hemisphere snow cover from as far back as 1850.

In this classroom activity, students analyze regional energy usage data and their own energy bills to gain an understanding of individual consumption, regional uses, costs, and sources of energy.

In this lab activity, students use a chemical indicator (bromothymol blue) to detect the presence of carbon dioxide in animal and plant respiration and in the burning of fossil fuels and its absence in the products of plant photosynthesis. After completing the five parts of this activity, students compare the colors of the chemical indicator in each part and interpret the results in terms of the qualitative importance of carbon sinks and sources.

In this interactive, students explore, at their own pace, how global climate change may affect health issues. Issues include airborne diseases, developmental disorders, mental health disorders, vector-borne diseases and waterborne diseases.

This interactive video series reviews global warming by recognizing the problem, addressing the sources and impacts, and weighing the options. It is a six-chapter series. Experts from different countries weigh in and answer some critical questions, including what countries have resources and the perspectives necessary to reach a consensus on handling the next steps and the economic costs involved.

In this video segment, two students discuss the greenhouse effect and visit with research scientists at Biosphere 2 in Arizona, who research the effects of global climate change on organisms in a controlled facility. Their current research (as of 2002) focuses on the response to increased quantities of CO2 in a number of different model ecosystems.
