A Warm Planet in a Cold Universe
Activities for teaching about climate and climate change
During the day, the earth is warmed by sunlight that shines on it. This is something that your students can see, something that they can feel. But, over the course of a day, the surface of the earth receives more radiant energy from the bottoms of clouds and the lower atmosphere than it does from the sun. This influence of thermal radiation is critically important for an understanding of the earth’s climate and how it is changing. In this workshop we’ll share activities that make this invisible form of energy transfer tangible. We’ll also share activities that illuminate other important but complex concepts, such as how climate models work, how feedbacks—both positive and negative—affect the climate. Our goal is to help you understand the nuts and bolts of climate and climate change and to learn tools and techniques for sharing these ideas with your students.
