科学家通过气候变化报告(Scientists Endorse Climate Change Report)

来自世界各地的科学家以及气候变化问题专家达成共识，认为世界已拥有应对全球变暖效应的技术和资金，但必须立即采取行动才能防止灾难的发生。

联合国政府间气候变化专门委员会的代表经过5天紧张讨论，星期五在泰国曼谷正式通过了一份报告。来自100多个国家的官员说，全世界必须立即行动，将全球升温控制在2摄氏度以内。

有关这份报告的讨论超过了预定时间，原因是富裕国家和贫穷国家在这个问题上有分歧。最大的分歧之一是减少导致全球变暖的温室气体排放究竟需要付出多大的经济代价。中国对减少温室气体排放带来的经济影响表示最为担心。

世界上最大的两个温室气体排放国美国和中国以及其它一些国家表示，建议的排放量上限可能会由于经济成本过高而难以落实有关规定。

Scientists and climate change experts from around the world have agreed that the world has the technology and money to manage the effects of global warming, but that it must act now to prevent disasters.

Delegates from the United Nations' Intergovernmental Panel on Climate Change formally endorsed a report Friday in Bangkok after five days of intense talks. Officials from more than 100 countries say the world must act immediately to cap the global temperature increase at two degrees Celsius.

Negotiations on the report lasted longer than expected because of disagreement between rich and poor countries. The costs of reducing greenhouse gasses that cause global warming was one of the biggest disputes, with China the leading voice of concern about the economic impact of cutting back.

Countries such as the United States and China -- the world's top two greenhouse gas producers -- say a proposed cap on emission levels could be too costly to implement.
