Global Warming Essay
What is global warming, and how does human activities create an impact on global warming? Many people do not understand the full concept of global warming. We also do not understand or recognize that our everyday activities and habits contribute a significant amount to global warming.
What is global warming? Global warming ( noun) is an increase in the earth’s atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution ( Merriam-webster dictionary), http://www.merriam-webster.com/dictionary/global+warming. The greenhouse effect is vital when dealing with our atmosphere and global warming. What is the greenhouse effect you wonder? The greenhouse effect is the warming of the earth’s atmosphere that occurs when the sun’s radiation passes through the atmosphere, is absorbed by the earth, and is given off a radiation of longer wave length which can be absorbed by atmospheric gases, such as carbon dioxide and water vapor. There are several atmospheric gases that make up the greenhouse effect. These gases are: Nitrogen (N2), Oxygen (O2), Argon (Ar), Carbon Dioxide (CO2), Neon (Ne), Helium (He), Methane (CH4), Krypton (Kr), Hydrogen (H2).
Although many do not realize it, human activities do create an impact with global warming. In 2005, global atmospheric concentrations of carbon dioxide were 35 percent higher than they were before the Industrial Revolution. Scientists have concluded that most of the observed warming is very likely due to the burning of coal, oil, and gases. Human activity, such as burning fossil fuels, causes more greenhouse gases to build up in the atmosphere. Fossil fuels such as oil, coal, and natural gases are high in carbon and when burned they produce major amounts of carbon dioxide (CO2). Driving a car puts more carbon dioxide into the atmosphere than anyone realizes. One gallon...
