An increase in the temperature of the Earth’s surface may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. One cause for Global Warming is called the Greenhouse Effect.
The Greenhouse Effect results from a four step process. First, sunlight radiates from the sun, through space, to Earth's atmosphere. Second, the sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat is absorbed by surrounding air and land, which in turn makes it warm. Third, infrared rays, which are remitted into the atmosphere, are trapped by greenhouse gases. Finally, the gas then absorbs the light and is remitted back to the......
