SPEECH: GLOBAL WARMING - A WORLD WIDE PROBLEM
Speech - Global warming
Specific purpose: To inform the audience about some effects of global warming so that they are able to discuss the problem surrounding the global warming after my speech.
Introduction:
Humanity is conducting an unintentional, unrestrained and globally perversive experiment whose ultimate consequences could be second only to nuclear war The human race is responsible for the biggest testing in history an experiment to see what will happen to our health and the health of the planet when we make dreadful changes in our climate. This is not a prescribed scientific inquiry. It is an enormous change in the Earth's environment, and we are gambling our children's future on the results. Our experiment is called global warming, and it is changing our atmosphere throwing out of balance a delicate system that almost took billions of years to develop. Global warming is a serious problem that cannot be ignored
I. Preview: Explaining the meaning of global warming, process of global warming and the effect of the global warming .
II. Main points:
I. Meaning of global warming: Generally, the global warming means to warming the global either by human being or by the environment but the intricate meaning is the increasing temperature of earth. Some scientists like to mention the global warming as green house effect. "Global warming has reached a level such that we can ascribe with a high degree of confidence a relationship between the green house effect and the observed warming". (1)
II Cause of global warming:
A. Global climate is changing because of the buildup in the atmosphere of carbon dioxide (CO2), methane, nitrous oxide (N20), and the CFC (powerful green house gases as well as destroyers of stratospheric ozone).(5)
B. Another reason of the global warming is green house effect. About 30 gases produced by human activity have been identified as contributing to the green house effect.
C. The US Government has acknowledged for the first time that
