Global Warming - Essay Example As the paper outlines global warming is related to the greenhouse effect, which is the course by which absorption and discharge of emissions of gases in the atmosphere warms the lower atmosphere and the surface of the globe. Global warming is as a result of reasons, which may be either natural or manmade. Natural causes are those that are created by nature, and are often related to the emission of methane gas. This is the case in the arctic tundra and wetlands. Methane, being a greenhouse gas, holds heat in the mesosphere. Another natural cause is the cycle of climate change that usually takes about 40,000 years. Human activities have been credited for the changes in climate as early as during the industrial revolution. Their activities lead to increased levels of greenhouse gases in the atmosphere. Pollution is the biggest problem and results from a number of activities, the main being burning of fossil fuels. These are fuels, resulting from organic matter such as oil and coal. The burning of fossil fuels emits carbon dioxide. The mining of oil and coal also allows methane gas to escape into the atmosphere. This is because methane gas exists naturally in the ground. An increase in the population has also been credited for global warming. As people settle in new areas they clear the vegetation that previously existed and cause deforestation. Plants are known to take in carbon dioxide and emit oxygen. Their clearance increases the amounts of carbon dioxide in the atmosphere. There are a number of effects resulting from global warming. Weather patterns are most affected by the climatic change.
