Scientific evidence appears to indicate that the accumulation of CO2 in the atmosphere from the burning of fossil fuels (primarily coal, oil, and natural gas) – mainly in electricity production, transportation, and various industrial processes – contributes to gradual global warming, with long-term adverse effects on living conditions around the world. It is with this in mind that representatives of more than 150 countries are scheduled to meet in Copenhagen in December to discuss ways to reduce CO2 emissions.
科学证据表明：由于燃料化石（主要是煤，石油和天然气）——主要是用于发电，运输和各种工业化等——在空气中的大量燃烧，使得二氧化碳在大气层中的含量不断升高，迫使全球气候变暖，由此威胁到我们生活的环境。因此，今年12月，全球150多个国家的代表将在哥本哈根聚集，共同讨论如何减少二氧化碳的排放量问题。
