Global temperatures on the Earth’s surface have increased by 1.1 degrees Fahrenheit during the last century, faster than any time in the last 1000 years (Rauber 41). Consequently, the 1990s was the warmest decade in the last 1000 years (“Global Warming”). As humans emit fossil fuels, greenhouse gasses slowly warm the Earth’s atmosphere (“EPA Global”). This gradual process is known as global warming. As glaciers begin to melt, sea levels rise and coastal areas in Florida may suffer immense losses (“Beach Erosion”). Florida’s tourist economy may also suffer a tremendous loss, as well as agriculture (“Florida Scientists”). With a warmer atmosphere, disease will spread quicker and human health will be threatened throughout the state (“Global Warming”). Serious action needs to be taken in order to slow the process of global warming.

Global Warming is an increase in the temperature of the Earth due to the use of fossil fuels and industrial processes that build up to the emission of greenhouse gasses, mostly carbon dioxide and methane (“Global Warming Threatens”). As energy from the sun strikes the surface of the earth, it turns into heat which, in turn, releases the heat as long-wave infrared radiation (Crowe). Gasses in the air, such as carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapor, trap some of this radiation as it tries to make its way back out to space (Olgesby). These gases trap in heat as do the windows of a greenhouse; therefore, they are called greenhouse gases (Elston). As an excess amount of these gasses are emitted into the Earth’s atmosphere by industries and fossil fuels, the temperature of the Earth’s atmosphere gradually increases (Oglesby). Humans escalate the amount of greenhouse gasses in the atmosphere by burning fossil fuels and by many manufacturing processes (Crowe). In the U.S., from 1990-1997, carbon dioxide emissions have increased 10.7 percent (Elston). This activity and a warming atmosphere are causing...
