Global Warming 1Running head: Impact of Global WarmingImpact of Global WarmingJoseph SmithUniversity of PhoenixGlobal Warming 2Is global warming a real issue or is this phenomenon just a fad? Was 2005 the warmest year on record? According to the National Aeronautics and Space Administration (NASA) the five warmest years (in order) on record occurred during 2005, 1998, 2002, 2003, and 2004. The rapid pace at which the temperature is rising will result in many negative impacts to humans and the environment. This is why global warming is such a world wide concern. I will discuss the effects of global warming and how it influences our environment. Living and nonliving factors that contribute to global warming, positive and negative impact of renewable energy resources, and different ways global warming can impact humans will also be discussed.Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades and its projected continuation into the future. The Earth's climate has changed many times during the planet's history with events ranging from ice ages to long periods of warmth. Historically natural factors such as volcanic eruptions, changes in the Earth's orbit, and the amount of energy released from the sun have affected the Earth's climate.Beginning late in the 18th century human activities associated with the Industrial Revolution have changed the composition of the atmosphere. The Industrial Revolution was likely to influence the Earth's climate. The burning of fossil fuels such as coal, oil, and deforestation has increased the risk of global warming.Global Warming 3Global warming's risk has increased due to the trapping of "greenhouse gases" that increases significantly into our atmosphere. These gases prevent heat from escaping into space and act somewhat like the glass panels of a greenhouse. According to the Environmental Protection Agency in 2002 agriculture, industry, transportation, residential, and commercial are the biggest contributors to greenhouse gases. The graph located on the right breaks down the percentage of each sector.Living and nonliving factors contribute greatly to the global warming issue. The National Aeronautics and Space Administration (2005) stated, "The main human activities that contribute to global warming are the burning of fossil fuels (coal, oil, and natural gas) and the clearing of land" (¶ 4). Human actives are a living factor that contributes to global warming because human activity is very destructive to the Earth's environment.Global Warming 4Most of the destruction and global warming can be blamed on the burning of fossil fuels powering automobiles, factories, and electric power plants that provide energy for houses and office buildings. The burning of fossil fuels creates carbon dioxide better known as chemical formula CO2. Fossil fuels pollute the air and cause respiratory problems that affect humans. An example of a respiratory issue...
