Global Warming 4
Human kind has entered a brand new relationship with the earth. The constant and increasing pressures we are exerting threaten our planets ability to sustain life itself. Change-in the way we think , and in the way we live-is needed now.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
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 earthıs surface. As warming continues, every place on the earth will be effected.In the frozen heart of the last ice age, 18,000 years ago, the temperature was only about nine degrees Fahrenheit colder then today. So a change of a few degrees can have a dramatic effects. Todays most sophisticated climatic models estimate the global temperature will rise between 3 and 9 degrees Fahrenheit in the next century.This could occur as early as the year 2050. Here are the large scale changes the rise might bring: As water warms it expands, taking up more space. So warmer ocean water, with added melt-water from glaciers, will rise by twenty inches to five feet in the next 50 to 100 years.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 changes are small, so far, but they are expected to grow and speed up. With
