最近100多年来,全球大气中的二氧化碳及其他微量气体(N_2O,CH_4,CFCS)迅速增加。据测,1985年大气中二氧化碳浓度已比工业革命前增加了约1/4,从而使世界平均气温升高。据1986年世界气象组织计算,最近100年来,世界平均气温已增加了0.3—0.7℃。估计到2050—2100年,全球平均气温将升高1.5—4.5℃。全球气温升高,将引起世界海平面上升。最近100年(1880—1980)来,世界海
Over the past 100 years, the global atmosphere of carbon dioxide and other trace gases (N 2 O, CH 4, CFCS) increased rapidly. It is estimated that the concentration of carbon dioxide in the atmosphere in 1985 has increased by about a quarter compared with that before the industrial revolution, resulting in an increase in the world average temperature. According to the World Meteorological Organization in 1986, the average temperature in the world has increased by 0.3-0.7 ° C over the past 100 years. It is estimated that by 2050 to 2100, the global average temperature will rise 1.5-4.5 ℃. Global warming will cause the world’s sea level rise. The last 100 years (1880-1980) come, the world sea
