This document discusses global warming, including its causes, effects, and precautions. It defines global warming as the increase of the Earth's average surface temperature due to greenhouse gases. Some of the key causes mentioned are the burning of fossil fuels and deforestation. Effects include various environmental and social changes. The document advocates reducing fossil fuel consumption and using alternatives like handkerchiefs and cloth towels to help slow global warming.

- 8. causes Of GLObaL WarminG Greenhousegases are released into the atmosphere in many ways, including through the burning of fossil fuels (such as coal and petroleum) and by deforestation. As some environments warm (e.g. the Arctic tundra) they also release carbon that may have been stored for thousands of years.

- 13. Because greenhouse gasemissions are tied very closely to our energy consumption, using less fossil fuel based energy puts fewer greenhouse gases into the atmosphere. This will help slow global warming. Reduce our consumption of fossil fuels Mountaintop removal for coal mining near Rawl, West Virginia. 50% of electricity in the United States is produced from coal.

Editor's Notes
- #3 In examining global warming, we will be looking at questions such as Is the world getting warmer? If so, are the actions of mankind to blame for earth’s temperature increases? What can or should be done about global warming? Are the potential resolutions to global warming worth the cost to implement them?
- #7 Likewise, the earth’s atmospheric gases affect the ability of the earth to radiate the Sun’s energy back into space. Nitrogen and Oxygen make up 99% of the earth’s atmospheric gases and are non-greenhouse gases. Water, Carbon Dioxide, and Methane make up 1% of the earth’s atmosphere, but are greenhouse gases, since they cause the earth to retain heat.
- #8 The temperature of the earth is directly related to the energy input from the Sun. Some of the Sun’s energy is reflected by clouds. Other is reflected by ice. The remainder is absorbed by the earth.
- #11 This spike is due to the exponential increase in the use of fossil fuels over the last 150 years. Shown here are emissions of carbon from gas, solid, liquid fuels, and the total carbon emissions.
- #12 Despite this rapid increase in carbon emissions, only about half the carbon can be detected in the atmosphere. The remainder of the carbon dioxide is being dissolved in the oceans or incorporated into trees.
