This video describes what black carbon is, where is comes from, and how it contributes to sea ice melt and global warming.

In this video, a PhD Student from the University of Maine explains how ice cores are used to study global climate change.

In this lesson, students explore several facets of the impact of volcanic eruptions on the atmosphere. Students analyze three types of visual information: a graph of aerosol optical depth v. global temperature, a global map with temperature anomalies, and an ash plume photograph. In the hands-on activity, students use math to determine the rate and estimated time of arrival of an ash plume at an airfield.
