Earth & Sky

Using data collected from Mauna Loa, students will graph changes in atmospheric levels of carbon dioxide (CO2) over a 46-year period, and identify possible reasons for those changes. They will also learn about the relationship between CO2 and the Earth’s climate, and explore ways to reduce the amount of CO2 they generate.
