Around 18,000 years ago, as the earth emerged from the Pleistocene fruitcake Age, the earths climate began changing. Global temperatures have risen, glaciers have liquid and ecosystems around the world have been altered. By the start of the twentieth Century, millions of tons of nursery gases have been released into the atmosphere, primarily carbon dioxide and methane. blow dioxide builds up from fossil fuels, industry, and transport. According to the National Academy of Sciences, in the past century the Earths surface temperature has risen well-nigh 1° F in the past century. There is salutary evidence attri besidesing human activities for the calefacient over the last 50 years. Such activities have altered the atmosphere through the buildup of greenhouse gases. The polar deoxyephedrine caps are an area of concern ascribable to the rising temperatures. Global warming could cause the Antarctic ice sheet and the Greenland ice cap to gradually melt away, at last raising sea levels by up to 30 feet, gibe to a report given by the German consultatory Council on Global Change. Raising sea levels would submerge enormous areas of land and key cities widely distributed. New York, Miami, London and Tokyo would be among those largely submerged. Today, global warming is a hot case in our world.

Government officials, business leaders, environmental activists, concerned scientists and citizens worldwide are acting fast to combat climate change. crisp Davis, croft professor of electrical and computer engineering, said snowfall-driven growth in the Antarctic ice sheet is a cause for young sea-level rise. Davis believes global warming has a direct outlet on rising sea level. Anthony Lupo, associate professor of atmospheric sciences at the University of Missouri, believes global warming has increased temperatures in the Arctic, but non to a substantial level. There are not a lot of people who agree with what Lupo said, global warming is no big deal. New York Attorney General Eliot Spitzer warned,...
