So what is Global Warming? According to the Oxford Dictionary Global Warming is the “increase in the temperature of the earth’s atmosphere caused by the greenhouse effect.” Although the concept of global warming had been lightly touched upon during the late 19th Century, only in recent decades has its significance been realized.

Some parts of the world will probably warm more than others. The warming of 2 to 5 degrees Celsius that scientists predict will occur by the middle of the next century is an increase in the average global temperature. Almost all climate models predict that warming will be greater at higher latitudes (nearer the poles) than at the equator. In fact, the warming t

A major concern is how global warming will affect agriculture. Climate affects when, where, and how the world grows its food. Most plants, including important food crops such as corn, wheat, and rice, are very sensitive to even minor changes in temperature and precipitation. The effects of global warming on agriculture will be different in different parts of the world. In areas of North America, Europe and Asia, where much grain is grown, hotter, drier conditions could spell disaster. In the long run, drought and summer heat could dramatically reduce food production in these regions.

In retrospect, the effects of Global Warming are a real danger, which the people of this planet must combat. The seriousness of the potential outcomes of global warming demands respect and the utmost attention. There are preventions for these effects, which should be implemented, particularly the cutting of greenhouse emissions from factories and machines. The dinosaurs faced extinction from a natural cause which they had no control over. Many humans may face a similar fate from a man-made cause which they have complete control over.

Chances are good that we will see more temperature extremes in many parts of the world because of global warming. This will be especially true in summer time, when temperatures are predicted to soar to all new highs. It is also possible that changes in temperature could cause dangerous kinds of weather, such as tornadoes and hurricanes, to become more powerful, more destructive, and more common. The strength of hurricanes, for example, is largely determined by the temperature of the ocean waters over which these storms develop. Some atmospheric scientists think that as global warming raises water temperatures near the oceans surface, hurricanes will have the potential to develop into even more ferocious storms than they are now.

As climate changes, so will the seasons. On the average, winters will probably be shorter and milder, and summers will be longer and warmer.

Higher air temperatures also increase the concentration of ozone at ground level. The natural layer of ozone in the upper atmosphere blocks harmful ultraviolet radiation from reaching the earth’s surface, but in the lower atmosphere, ozone is a harmful pollutant. Global warming may also increase the risk of some infectious diseases, particularly those diseases that only appear in warm areas. Diseases that are
