Using data collected from Mauna Loa, students graph changes in atmospheric levels of carbon dioxide (CO2) over the course of several decades and identify possible reasons for those changes. They will also explore the relationship among CO2, the Earth’s climate, and local ecosystems and suggest ways to reduce the effects of increased CO2 levels in the atmosphere.

Objectives

Students will

  • Examine and analyze trends in CO2 levels.
  • Learn how an increase in temperature can affect ecosystems.
  • Suggest ways to reduce the effects of elevated CO2 in the atmosphere.
