effects of global warming


Over time, the average temperature on the earth’s surface constantly goes up and down. These changes are most often the result of differences in the amount of heat from the sun or natural changes in the atmosphere. It usually takes thousands of years for the temperature to change by even one degree Celsius. However, recent measurements show that the earth’s temperature may have increased by almost this much in only the past 100 years. Some scientists believe that this rapid temperature change is the result of human, not natural, activity. The name for this kind of unusual change is global warming, and some scientists and meteorologists predict that it may cause serious problems around the world in the near future. Some even believe these problems are already beginning to happen. While not all meteorologists and scientists agree that global warming is a reality, those who do agree have some serious concerns. They expect an increase in heat waves along with extremely heavy thunderstorms and floods in the near future. Some also predict that snowstorms will become more frequent and intense as global warming causes the level of moisture in the air to rise. In addition, others predict that the size and strength of hurricanes and typhoons will increase as the temperatures of the oceans rise. These scientists also emphasize that people living in cities near the ocean or on small islands should be particularly concerned. They suggest that, as the earth’s temperature increases, the ice at the north and south poles will begin to melt and cause sea levels to rise. This rise in the world’s oceans will, in turn, cause coastal flooding. One prediction is that by the year 2100, sea levels will be three feet higher than they are today. This would mean that cities like Venice, Italy, and Miami, Florida, could lose significant amounts of land to the ocean. Although these are only predictions, the governments in most major countries are beginning to take them seriously. average a. 平均的 Celsius n. 摄氏 concern n. 担忧 intense a. 强烈的 hurricane n. 飓风 emphasize vt. 强调 concerned a. 担忧的 in turn 反过来 coastal a. 海岸的 Venice 威尼斯 (意大利城市) Miami 迈阿密 (美国城市) Florida (美国)佛罗里达州
