• 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. 

Positives

• 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.

Differentiation

• 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.
