Document Summary

The introduction in the textbook provides an excellent overview of global warming. Define global warming and summarize its effects providing numerical evidence where possible. Global warming = gradual increase in the overall temperature of the earth"s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, methane and water vapor. View the animation global warming and the greenhouse effect and draw a diagram to illustrate what happens to the short-wave radiation from the sun after it enters earth"s atmosphere. Once visible light has entered the earth"s atmosphere, the earth"s surface absorbs the solar energy and releases it back to atmosphere as infrared radiation. Some is absorbed by greenhouse gases (methane, water, carbon dioxide) and is sent back towards earth"s surface (heat reradiated back to earth) warming the surface. Today"s levels of carbon dioxide are causing excess warming. Methane (ch4) = made by fermentation of organic matter (domesticated livestock farts)
