Ume SITC ABSTRACT Global†¦show more content†¦Scientists have spent decades figuring out what is causing global warming. They have looked at the natural cycles and events that are known to influence climate. But the amount and pattern of warming that is been measured can t be explained by these factors alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans. One of the first things scientists learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture (especially from the digestive systems of grazing animals), nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwis e store CO2. Desertification could be described as the spread of a desert environment into arid or semiarid regions, caused by climatic changes, human influence, or both. (Cline 2007) Climatic factors include periods of temporary but severe drought and long-term climatic changes toward dryness. Human factors include artificial climatic alteration, as through the removal of vegetation (which can lead to unnaturally high erosion), excessiveShow MoreRelatedEnvironmental Control and Pollution in Nigeria6978 Words   |  28 Pagesproblems.
