Global Warming Global Warming, aside from pollution is one of scientists biggest concerns. Global Warming is caused by the Greenhouse effect. There are 4 steps in the Greenhouse effect process. The first is, sunlight radiates from the sun, through space, to the Earth’s atmosphere. The second is, sunlight enters the atmosphere and hits the Earth. Some of that sunlight turns into heat energy in the form of infrared light. Surrounding air and land, which in turn makes the heat warm, absorbs the heat. Third, the greenhouse gases trap infrared rays that is remitted into the atmosphere. Finally, the gas then absorbs the light and is remitted back to the Earth’s surface and warms it even more. Another cause of Global Warming is the emissions of greenhouse gases due to the increase in technology that humans have developed. The problem of global warming, an increase in the average temperature on Earth, is getting worse. The Earth has warmed 0.3 to 0.6 degrees Celsius since the late 1800s. Scientists believe that the cause is the greenhouse effect, the process of trapping heat in the Earth’s atmosphere because of the presence of large amounts of carbon dioxide, chlorofluoro carbons, methane, and nitrogen oxides. Less oxygen is
