Global Warming

Global warming is an increase in the average temperature of earth's surface. Since the late 1800 the global average temperature has incresed about 0.7 to 1.4 F (0.4 to 0.8 C). many experts estimate that the average temperature will rise to 2.5 to 10.4 F . that rate of increase would be much larger than most rates of past increases. Scientists are worried that human societies and natural ecosystem might not adapt to rapid climate changes. An ecosystem consists of the living organism and physical environment in a particular area. Global warming could cause much harm, so countries throughout the world have issued and agreement to limit it. However,that agreement know as the kyoto protocol has not yet been ratified. Moreover, the government's concerns start to emerge.
