This month, thousands of people from all over the world, including many heads of state, will gather in Copenhagen to try to forge an agreement to drastically cut atmospheric emissions of an invisible, odorless gas: carbon dioxide. &#160;Despite efforts by some leading countries to lower expectations ahead of the conference about what can and will be achieved, the meeting is still being called the most important conference since World War II. &#160;And at the conference’s heart are the results of Tyndall’s experiments.
这个月，来自世界各地的数千人，包括众多国家首脑将汇集哥本哈根，力求达成大幅削减二氧化碳这种无色无味气体大气排放的相关协议。尽管某些大国在会议召开前试图降低人们对于成果的期望值，但这次会议仍然被誉为二战结束后最重要的会议。廷德尔实验是这次会议的核心议题。
