 * 3) Nitrous Oxide(N2O)
 * 4) Fluorinated Gases or High GWP Gases

Facts:
 * 1) Carbon dioxide enters the atmosphere through the burning of fossil fuels(oil, natural gas, and coal)
 * 2) Methane is emitted during the production and transport of coal, natural gas, and oil
 * 3) Nitrous oxide is emitted during agricultural and industrial activities
 * 4) Fluorinated gases or high GWP gases are emitted from the creation and/or use of refrigerators, air conditioners, and foams
 * 5) Greenhouse gases keep heat from the sun in the lower part of the earth's atmosphere rather than letting it escape back to space
 * 6) Greenhouse gases absorb solar energy and trap it in the atmosphere
