Global warming refers to a phenomenon occurring on Earth 's surface as a result of increasing global temperatures. Increased temperatures are as a result of the accumulation of greenhouse gases such as carbon dioxide, water vapour, nitrous oxide and methane gas in the atmosphere. The greenhouse effect is a natural system that regulates the temperatures on Earth by trapping the sun 's heat to keep the temperature on the surface warm enough to support life. However, increasing levels of the greenhouse gases as a result of industrialization and rising population continue to increase the temperatures on the Earth 's surface causing various physical, environmental, climatic and ecological changes on…
