Global warming refers to the increase in the average temperature of both the earth’s near surface air and the oceans. The temperature increase began in mid twentieth century and is predicted to continue into the future. For example, during the last hundred years ending in 2005, the earth’s surface air temperature has increased drastically (Thomas, C. D, 2004) . The increasing global temperature causes changes such as rising sea levels, which is consequently expected to increase the occurrence of extreme weather events (hurricane, floods, famine). In addition, the amount and pattern of precipitation is affected by increasing global temperature. The effects of global warming have been in the past disastrous and may be very disastrous even in the future. Other climatic change effects include, low agricultural yields, trade routes, glacier retreat, species extinctions and disease vectors increase. The paper will discuss the causes of global warming, the effects and measures that have been taken to reduce it.

Causes of Global warming

The greenhouse gases emissions have greatly contributed to global warming and still continue to be a threat even in the modern world. Examples of greenhouse gases are, carbon dioxide, methane, water vapor and nitrous oxide. Carbon dioxide emissions may come from the power generating plants, vehicles, airplanes and industrial pollution.
Carbon dioxide from power plants stems from electricity generation through the burning of fossil fuels. Coal as a raw material accounts for a high percentage of the carbon dioxide emissions due to its use in the electricity utilizing industry. For example, in 2002, 40% of U.S. carbon dioxide emissions was estimated to be from fossil fuel burning. As compared to the natural gas coal emits much more...
