C-ROADS is a simplified version of a climate 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.

This resource is designed as a module with a storybook or web story, and four activities. In the storybook, the GLOBE Kids investigate colors in the sky and learn how air pollution affects sky color and our health. Learning activities engage students in describing sky color and conditions in the atmosphere, creating a model to learn how sky color and visibility are affected by aerosols, using prisms to explore properties of light and colors, and collecting aerosol samples.
