The Greenhouse EffectStreaming Video - 2006
A life-sustaining envelope of gas surrounds the earth. This atmosphere contains oxygen, CO2, water vapor, and other gases-it is what generates climate, which affects all living beings. This program analyzes the sun's gradual brightening and the relationship between sunlight and CO2, explains why the atmospheres of Mars and Venus cannot sustain life, theorizes about the disappearance of dinosaurs and a dinosaur-friendly climate, and explains the relationship between climatic change and continental drift.
