Two short, narrated animations about carbon dioxide and Earth's temperature are presented on this webpage. The first animation shows the rise in atmospheric CO2 levels, human carbon emissions, and global temperature rise of the past 1,000 years; the second shows changes in the level of CO2 from 800,000 years ago to the present.

In this short video, atmospheric scientist Scott Denning gives a candid and entertaining explanation of how greenhouse gases in Earth's atmosphere warm our planet.

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 full color, worldwide, animated weather map using GIS interface showing current and projected wind and other weather conditions for any location in the world. Data can be viewed at different spatial scales.
