This textbook chapter summarizes the changes in the ecosystems found in the world's forests. This is chapter 2 in the unit, A New World View, which introduces global systems science, emphasizing the concepts of environmental diversity, Earth as a... (View More)

This textbook chapter presents evidence of a warming climate and outlines how a clear picture of global warming has emerged since the 1980s. Students learn about sampling error sources in climate data, and compare graphical data collected by climate... (View More)

Students will use NASA's Global Climate Change website to research five of the key indicators (vital signs) of Earth’s climate health. These indicators are: global surface temperature, carbon dioxide concentrations, sea level, Arctic sea ice, and... (View More)

This chapter describes how to set a scale and measure distances and areas on satellite images. Using ImageJ, a freely available image analysis program that runs on most operating systems, users set the spatial calibration of an image, then select... (View More)

In this activity, users examine satellite images from NASA's Total Ozone Mapping Spectrometer (TOMS) that show how much ozone is in the atmosphere over the Southern Hemisphere. They interpret the images to identify ozone thinning that develops over... (View More)
