Model Essay for students on global warming.
Global warming is gauged by the increase in the average global temperature of the Earth. Along with our currently increasing average global temperature, some parts of the Earth may actually get colder while other parts get warmer—hence the idea of average global temperature. Greenhouse gas-caused atmospheric heating and agitation also increase the unpredictability of the weather and climate.
Global warming starts with the greenhouse effect, which is created by the relationship between the radiation from the sun and the Earth's atmosphere. Human activity also introduces specific types of gases into the Earth's atmosphere. As of 2005, as a result of these circumstances, over the last 50 years, the average global temperature of the Earth has experienced the fastest growth rate in.
Global warming is an extremely severe problem facing the world today. Its effects and causes have been on the rise and people need to do something about it before the problem gets any worse. Global warming is an increase in the earth's temperature, which can be caused by the use of fossil fuels, and industrial or agricultural processes. Man-made emissions are adding to the amount of carbon.

The effects of global warming or climate damage include far-reaching and long-lasting changes to the natural environment, to ecosystems and human societies caused directly or indirectly by human emissions of greenhouse gases. It also includes the economic and social changes which stem from living in a warmer world. Many physical impacts of global warming are already visible, including extreme.
While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases. By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the.
Global warming is the increase of average world temperatures as a result of what is known as the greenhouse effect. Certain gases in the atmosphere act like glass in a greenhouse, allowing sunlight through to heat the earth's surface but trapping the heat as it radiates back into space. As the greenhouse gases build up in the atmosphere the Earth gets hotter. This process is leading to a rapid.
