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 also explore the relationship among CO2, the Earth’s climate, and wildland fires and suggest ways to reduce the effects.

Objectives

Students will

  • Examine and analyze trends in CO2 levels.
  • Learn how an increase in temperature is related to wildland fires.
  • Suggest ways to reduce the effects of elevated CO2 in the atmosphere.
