Includes natural changes (cyclic variability, volcanic eruptions, solar output) and human-caused changes (due to GHG emissions and land use changes)

In this activity, students explore factors that have caused the rise in global temperature over the last century. Educators have the opportunity to assess how modeling activities (the game), analogies (the cake), and mathematical models (graphs) develop and change student mental models.

This is a series of graphical animations that compare the contribution of natural factors (including orbital changes, variability in the sun's temperature, volcanic action, deforestation, ozone pollution levels, and aerosols) to the contribution of increasing atmospheric carbon dioxide, to increases in global atmospheric temperature... in a visual and concise way.

This video introduces phytoplankton - the base of the marine food web, the source of half of the oxygen on Earth, and an important remover of CO2 from the atmosphere. The video also explains how satellites are used to monitor phytoplankton and how warming waters and acidification negatively affect phytoplankton.

In this interactive simulation, students can explore global CO2 emissions displayed by different continents/countries and plotted based on the GDP. A map view is also accessible.

This short video, is the fifth in the National Academies Climate Change, Lines of Evidence series. It focuses on greenhouse gases, climate forcing (natural and human-caused), and global energy balance.
