Geography - Climate and Weather - Climate change and global warming - The Greenhouse Effect
A 5-step explanation. Step 1: 'Solar Energy In' - Sun's rays pass through atmosphere, warm Earth's surface. Step 2: 'Heat Radiates Out' - Warmed surface radiates infrared (heat) back toward space. Step 3: 'Greenhouse Gases Trap Heat' - CO2, methane, and other gases absorb some infrared, warming the
