Introduction

OUTLINE I. Introduction A. Islands sinking into the ocean, rainforests dying, glaciers melting, hurricanes, mudslides...etc. B. Global warming, while still in debate, is a current social problem that threatens our future economy, environment, and lifestyle. Despite this, the United States government is doing remarkably little to help solve the problem. II. Background Information A. The possible warming of Earth due to heat-trapping pollutants in its atmosphere. Recognized in late 1980's IPCC B. Greenhouse gasses are the main problem. Carbon dioxide Nitrous oxide Methane HFC's, PFC's, and SF6 III. Discussion A. Global warming has already had effects on the Earth that may be permanent. B. (Costs) Grim Predictions of the effects of global warming have been forecasted by scientists C. (Contributing Factors)The United States emits more greenhouse gasses than any other country. IV. Solutions A. Scientists have speculated many ways to decrease greenhouse gasses and slow global warming, but none of them have been actually used. IPCC suggestions- expensive Fuel cells- currently in development Carbon separation- currently in development Iron sulfate in oceans- hurt ecosystems, CO2 may return to the atmosphere Liquefy carbon- acidity may kill marine life Kyoto Protocol- President Bush did not agree V. ...read more.

Insect, bacteria, virus, and fungi amounts and diversity increase in warmer temperatures (Global Warming International Center1 1). If the Earth warmed than 3 degrees Fahrenheit, crop harvests in the United States would begin to decrease (Lemonick2 28). Unpredictable rains and fierce storms are predicted to increase (Tidwell E01). Tuvalu and Kiribati, small islands in the South Pacific, already flood frequently as ocean water expands and ice melts in higher temperatures (E01). Tuvalu's government is preparing a plan to evacuate its islands (E01). The most vulnerable areas to global warming are polar areas, coastal areas, Africa, large cities, and tropical areas (E02). Polar areas are in danger as ice melts; Antarctic penguins are decreasing and polar bears have less cubs (E02). Sea level is predicted to rise as much as three feet by 2100, this will inundate coastal areas, which contain 70% of the world's population (E02). Africa's animal migrations depend on rain patterns (E02). Global warming may disrupt the rain and negatively affect animals (E02). Large cities may suffer in intense heat, which negatively affects air quality (E02). Tropical storms are predicted to increase, as El Nino becomes more fierce (E02). The United States emits more greenhouse gasses than any other country (Kluger 30). ...read more.

Conclusion

First, every developed nation can reduce greenhouse gasses in simple, relatively inexpensive ways. Miami-Dade county recently reduced greenhouse gasses by 900 tons a year; they simply created road lanes for busses only (Kluger 36). This encouraged public transportation, greatly reducing greenhouse gas emissions. Every country can generate power using renewable resources that are easily found in their area. Mexico is already doubling its geothermal power, which is generated by underground heat (35). The European Union generates 15 gigawatts of energy using wind power, and the Netherlands is establishing its own wind power plant (35). Solar power and fuel cell power could also be used, and fossil fuel use could be discouraged by taxation. Also, too much money is being spent on researching the possible effects of global warming, when those scientists could be researching how to reduce greenhouse gasses. Global warming could destroy our future or not affect it at all. There is still hope, which grows stronger with every scientific advance. By taking the well-known concept- "Reduce, Reuse, and Recycle"- to heart, individuals can help reduce the possible effects of global warming. To completely solve global warming, governments and scientists from every nation must cooperate. The Kyoto Protocol and the IPCC are significant steps in the journey to solve global warming, and perhaps a solution will come soon. ...read more.
