低碳背景:1988年是有史以来最热的一年,69个美国城市,还有莫斯科,创下了最高的单日高温纪录。在洛杉矶,温度计的水银柱指向了110华氏度(43摄氏度),一天之内有400个变压器爆炸。美国中西部遭受了自黑风暴以来最严重的旱灾,而黄石国家公园几乎要燃烧起来。一个判断:詹姆斯·汉森——国家航空和航天局戈达德空间研究中心主任,在美国参议院能源和自然资源委员会上作证时说: “温室效应的存在业已查明,此时它正改变着我们的气候。”他百分之九十九地相信,目前的高温表明确有天气变暖的趋势,而不仅仅是自然变化。他补充说, “我们正在以不正当的手段破坏气候。”就在那个冗长的夏季,联合国环境
Low-carbon background: 1988 was the warmest year ever with 69 U.S. cities and Moscow, setting the highest single-day record. In Los Angeles, the thermometer’s mercury column pointed at 110 degrees Fahrenheit (43 degrees Celsius), and within a day 400 transformers exploded. The Midwest suffered its worst drought since the Black Storm, and the Yellowstone National Park almost burned. One judgment: James Hansen, director of the Goddard Space Research Center at NASA, testifying before the United States Senate Committee on Energy and Natural Resources, said: “The existence of the greenhouse effect has been identified as it is changing Our climate. ”He believes ninety-nine percent of the current high temperature shows that there is indeed a trend of warming, not just the natural changes. He added: “We are damaging the climate by improper means. ” Just that long summer, the UN environment
