This graph, based on key ice core data sets and recent monitoring programs, shows the variations in concentration of carbon dioxide (CO2) in the atmosphere during the last 400,000 years.

This NASA video explores the relationship between climate and agriculture, including the variability of climate change impacts that may occur in different regions and the effects of population growth and higher demands for food in areas that already struggle to supply food for the people. The video highlights the need for accurate, continuous, and accessible data and computer models from NASA satellites to track and predict the challenges farmers face as they adjust to a changing climate.

This figure, the famous Keeling Curve, shows the history of atmospheric carbon dioxide concentrations as directly measured at Mauna Loa, Hawaii. This curve is an essential piece of evidence that shows the increased greenhouse gases that cause recent increases in global temperatures.

This engaging activity introduces students to the concept of albedo and how albedo relates to Earth's energy balance.

This activity focuses on wind energy concepts, which are introduced through a Reading Passage and by answering assessment questions. Students construct and test a windmill to observe how design and position affect the electrical energy produced.

Students investigate passive solar building design with a focus on heating. Insulation, window placement, thermal mass, surface colors, and site orientation are addressed in the background materials and design preparation. Students test their projects for thermal gains and losses during a simulated day and night then compare designs with other teams for suggestions for improvements.

In this activity, students collect weather data over several days or weeks, graph temperature data, and compare the temperature data collected with long-term climate averages from where they live. Understanding the difference between weather and climate and interpreting local weather data are important first steps to understanding larger-scale global climate changes.

In this activity, students explore how, in New England, the timing of color change and leaf drop of deciduous trees is changing.

This is an animation from the US Environmental Protection Agency's Students Guide to Global Climate Change, one of a series of web pages and videos about the basics of the greenhouse effect.

This activity from NOAA Ocean Service is about using aerial photographs to assess the impact of extreme weather events such as Hurricane Katrina. The activity features aerial views of Biloxi, MS post-Katrina and enables students to see evidence of the power of extreme weather on the environment.
