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.
Ce mois-ci, des milliers de personnes du monde entier, chefs d’état y compris, se retrouveront à Copenhague pour tenter de rédiger un accord visant à réduire de manière drastique les émissions d’un gaz invisible et inodore&#160;: le dioxyde de carbone.
