What exactly are the causes of global warming? Is there anything that can be done about it? These are the questions that have become the main focus of arguments and lectures around the world regarding global warming. Global warming is a major Atmospheric issue that has been damaging our precious environment for many years. In recent years the issue of global warming has become an increasingly popular matter among society. Both the causes and effects of global warming have been the topic of heated debate not only among scientists, but among politicians, businesses, and general members of society as well.
Global warming is defined as a measurable increase in temperature of Earth's atmosphere, oceans, and landmasses. Greenhouse gases have been pinpointed as the main cause of this increase in temperature. The burning of fossil fuels such as coal, oil, and natural gas have caused a thirty-five percent increase in carbon dioxide (a highly potent greenhouse gas) since the 1750's (MSN Encarta, 2008).

Se belowSince the Industrial revolution in the mid 1700's there has been a significant increase in the production of greenhouse gases. Greenhouse gases such as water vapor and methane occur naturally in the environment. Other greenhouse gases, like hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride are created as a result of the industrial process which is used by humans (West, 2009). Greenhouse gases are the main contributing factor to global warming and climate change. These gases allow the Sun's radiation to heat the earth, much like the glass panes in a greenhouse. These gases also prevent the escape of infrared energy that is radiated from the Earth, which ideally would escape into space (MSN Encarta, 2008).
Apart from greenhouse gases, deforestation has also been recognized as a major contributing factor in global warming. Deforestation is a negative impact...
