Worksheet for Greenhouse Effect 101 Video

Everyone needs to know the basic science of the Greenhouse Effect. The Greenhouse Effect shows how CO2 is raising the average temperature of the globe, changing the climate in new and dangerous ways.

Objective: You will be able to:
-describe and explain the seven steps of the Greenhouse Effect.
-name the human activities which emit CO2 into the air (from largest to smallest percent of total human emissions).
-explain the importance of rising CO2 in the air.
