Sunlight, a form of electromagnetic radiation, heats the Earth's surface. The warmed Earth then emits energy in the form of infrared radiation. This energy travels back towards space. Greenhouse gases, such as carbon dioxide and methane, trap some of the infrared radiation in the atmosphere before it can escape, making the Earth warmer.
