Global warming is the most urgent environmental problem the world will face in the next decade and the next century. Few, if any, trends are more important to our future than climate change caused by human activities. Scientist around the world are warning us that global warming poses a major threat to our future quality of life, previously there has been little information on this problem. Right now, the rate of global warming may be 100 times faster than it has ever been. Very soon the earth may become hotter then at any time in human history. In the last decades the problems of atmospheric change have been gravely advanced by pollution resulting from human activities. These environmental changes pose a real threat to the lives of people and wild life.

It is vital to all of us that we fully understand the complex relationship between the atmosphere and the earth. The earth is getting warmer. The changes ar

e small, so far, but they are expected to grow and speed up. Within the next 50 to 100 years, the earth will continue to heat up hotter than it has been in the past million years.

In the southern hemisphere, the warming is the greatest over Australia, southern South Africa, the southern tip of South America, and the area of Antarctica near Australia. In the northern hemisphere, warming is strongest in Alaska, northwest and eastern Canada, most of the Soviet Union, and parts of Southern Asia, North Africa and southwest Europe. Climate has cooled in Great Britain and northern and eastern Europe. In the USA scientists found no overall warming trend in weather records kept since the nineteenth century, however keep in mind the United States covers only 1.5 percent of the earth’s surface. As warming continues, every place on the earth will be affected.

Just a 1 foot rise in sea level can cause shorelines to recede a hundred feet, and in flat terrain, a thousand feet. If ocean waters rise several feet, whole beaches could wash away. Many homes, hotels, other buildings, and entire cities will be threatened. Salt water will pollute freshwater wells that millio
