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.

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 millions of people use for drinking water. Coastal marshes, which are vital nurseries for fish and other ocean life will be endangered. Along undeveloped coast, marshes may survive because they can move inland with the rising waters. In many places seawalls and other human structures will prevent this process and the marshes will be destroyed.

as oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crops to fail. Global warming will effect weather everywhere, plants and animals everywhere and people everywhere.

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
