global warming

Global warming is an extremely severe problem facing the world today. Its effects and causes have been on the rise and people need to do something about it before the problem gets any worse. There are numerous groups of people and articles which deal with the disastrous effects. As we go about our daily lives we seldom think how the way that we live affects the environment around us. It is important to understand and discuss the significance of global warming. Global warming has great effect on crops and weather conditions around the world. The northern hemisphere contains more land area than the southern hemisphere, and conversely, a lower percentage of the world's oceans. Since oceans absorb more heat than land areas, it is not surprising that most climate models predict faster heating over the northern hemisphere than the global average. So we have to realize that we have much more in common with the plants, animals, air and water than we have with the mechanical, chemical and electronic world we have created around us. We have to remember that if we don't try, nobody will be able to stop the world and get off.
