What Is The Natural Greenhouse Effect?

The Greenhouse Effect is a big part of why Earth is able to sustain life. But, how much is too much? In part two of an eight-part series about the carbon cycle, environmental scholars learn how the natural Greenhouse Effect keeps us warm ... but the added greenhouse gases produced by burning fossil fuels is slowly but surely trapping too much heat. Clear narration and easy-to-follow animated sequences explain the effect perfectly.
