Global warming is defined as the warming of the earth by greenhouse gases emitted into the atmosphere naturally or by mankind. But there are many questions about global warming, from its causes to its full effects. Many people even question whether or not global warming exists. And if global warming does exist, people question why it exists. But there is one fact that no one has questioned-the surface temperature of the earth has increased by 0.55-0.6 degrees Celsius in the past century. Is the increased temperature something we need to worry about? Well, there are two different viewpoints. The believer in global warming exists, and that its a significant problem that should not be taken lightly. Skeptics of global warming believe that the increased temperature is a natural phenomenon, and that if global warming does exist, its not something to be worried about. What makes this debate so interesting is that there is valid scientific data to prove either side. Global warming has been proven and disproven using computer climate models. Believers in gloal warming use them to show that in the next century there will be a significant rise in the Earths temperature, and an increase in the height of sea level. Global warming skeptics suggest that the models are not completely based on fact, and what they can not be trusted. 1.What environmental issue is talked about in this article?A. Global warming. B.
