The Basics of Global Warming: Normally (the left image), some of the sun's energy re-radiates back into space and some is trapped by the Earth's atmosphere, which keeps our temperatures within stable bounds. As human-generated greenhouse gases enter the atmosphere (the right image), it traps more infrared radiation. As a result, the temperature of the Earth rises. And is doing so to dangerous levels.
