Weekly Atmospheric CO2 at Mauna Loa

Ask a Question

  • This short animated video shows the atmospheric concentration of carbon dioxide from 2007-2021. 
  • These measurements were taken at the Mauna Loa Observatory in Hawai'i. 
Teaching Tips


  • The lines on this animated graph build on each other, showing exactly how much atmospheric carbon dioxide has increased in recent years.

Additional Prerequisites

  • Students should have a basic understanding of climate change and the greenhouse effect.
  • Students should know that carbon dioxide is the greenhouse gas most responsible for global heating.
  • Scientist Charles David Keeling began measuring atmospheric carbon dioxide at the Mauna Loa Observatory in Hawaii in 1958.


  • This would be a great video to show at the beginning of a lesson on climate change. It may be powerful to show this video before explaining the context. You can have students write down three "noticings" and three "wonderings" about this video.
  • You can ask students about the average increase per year and see if they can figure out how decomposition and photosynthesis affect the level of CO2 throughout the year.
  • Students can access real time data from NOAA to see current levels of atmospheric carbon dioxide.
Scientist Notes
Using empirical data from the Mauna Loa observatory, this 31-second video shows both the annual cycle of carbon dioxide as well as the continued yearly increases in atmospheric carbon dioxide concentration. This resource is recommended for teaching.
