Document Summary
1 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 is the progressive increase of earth"s average temperature that has been occurring over the past century. Rising temperatures brought about by global warming are causing ice all over earth"s surface to melt. As this stored water runs off the land and into the oceans, sea levels rise. 2 view the animation (cid:498)global warming and the greenhouse effect(cid:499) and draw a diagram to illustrate what happens to the short-wave radiation from the sun after it enters earth"s atmosphere. Warmth from the sun heats earth"s surface, which then radiates the heat energy outward. Most of this heat is radiated back into space, but some of the heat warms up the green- house gases in the atmosphere and then is reradiated to earth"s surface. In effect, greenhouse gases act like a blanket.
