During the day, the earth is warmed by sunlight. But, over the course of a day, the surface of the earth receives more radiant energy from the bottoms of clouds & the lower atmosphere than it does from the sun! This influence of thermal radiation is crucial to understanding the earth's climate & how it is changing. Join LSOP & explore activities to understand the nuts & bolts of climate and climate change. Learn techniques for sharing these ideas with your students. Receive lessons & a surprise!
