This video succinctly explains the mechanism of the natural greenhouse effect and the cause of global climate change (anthropogenic global warming). It is short, basic, and to the point. It's also available in 12 languages!

In this activity, students learn about the scientific evidence supporting climate change, use this information to evaluate and improve conclusions some people might draw about climate change, and participate in a role-play to negotiate solutions to climate change.

This set of activities is about carbon sources, sinks, and fluxes among them - both with and without anthropogenic components.
