Keeling's Curve: The Story of CO2
Provided by: American Museum of Natural History |Published on: January 4, 2023
Videos Grades 6-8
Synopsis
- This short video explains the discovery of the rise in global CO2 concentrations by George Keeling.
- The video works chronologically through the discovery of a pattern in CO2 concentrations, examining those findings, analyzing the seasonal variation and causation, and ending with future projections.
Subjects: Biology, Earth and Space Sciences
Authors: American Museum of Natural History
Region: North America, USA - West, United States, Global

Teaching Materials
Positives
- This video is an easy-to-understand way to learn about one of the most important discoveries in climate science.
- The video is engaging, making use of a variety of graphics, charts, and images.
Additional Prerequisites
- The video does not include narration and requires students to read the text on the screen.
- Students should be able to read graphs and identify patterns before watching the video.
- Students should understand the difference between CO2 emissions and CO2 concentrations.
Differentiation
- It may be best to pause the video at times to give students a chance to analyze the graphs themselves.
- This video can easily connect to lessons about photosynthesis, decomposition, seasons, and the carbon cycle.
- Social studies and history students can connect this video to other current events happening in 1958 and think about which activities and industries contributed the most to the increase in carbon dioxide since then.
- As a follow-up activity, have students compare the ppm of CO2 in the atmosphere at the time of Keeling's discovery, the year they were born, and today.
- Have students reflect on the implications of Keeling's discovery, researching how this discovery impacted policy in the proceeding years, decades, and today.
