Greenhouse Gases
A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would average about 33 °C colder, which is about 59 °F below the present average of 14 °C (57 °F). Greenhouse gases however can affect the Earth in a very negative way. Greenhouse gases are dangerous to the environment. The most prevalent greenhouse gas is carbon dioxide. Carbon dioxide and other greenhouse gases are released into the atmosphere by agricultural practices and by the burning of fossil fuels. Greenhouse gases can be seen in populated cities throughout the world, when a car is started and smoke is emitted from the muffler, and industries burning toxins in which they create. All of these gases are harmful to the environment. One of the dangers of greenhouse gases is global warming. Polar ice caps are melting as a result of the greenhouse effect and this increases the sea level and cause floods to the coastal areas. Greenhouse gases, which increase the temperature around the globe, cause the tides to rise. The ocean is the largest ecosystem and it changes the waters and releases ice that has been frozen for long periods of time. Ice melting as a result of greenhouse gasses inhibits measurements in which scientists use in studying the changes in the climate. Therefore greenhouse gases are a danger in climate changes on earth. The greenhouse gases are a danger to the environment as it alters the weather. When the temperature increases evaporation of water increases as well. This brings about an increase in rainfall as well as dryer soil because of evaporation. This can change...
