Increased Emissions: Climate Change, Lines of Evidence

This video is one of a seven, Climate Change: Lines of Evidence series, produced by the the National Research Council. It outlines and explains what evidence currently exists in support of humans playing a role in contributing to the rise in atmospheric carbon dioxide levels.

Teaching Tips

If video is implemented in middle or high school classrooms, pausing periodically to review and discuss might help students absorb the breadth of the information.

Prepare handouts with the different graphs and let students take notes directly on them.

Provide students the opportunity to ask questions and research how the data was collected, limitations of the data sets, and assumptions made in the data analysis.

The following resources may give students the opportunity to easily analyze the data presented in the video:
