BERLIN – On June 10, 1859, six months before Charles Darwin published his Origin of Species , the physicist John Tyndall demonstrated a remarkable series of experiments at the Royal Institution in London. The meeting was chaired by Prince Albert. But neither he, nor Tyndall, nor anyone in their distinguished audience could possibly have anticipated the extent to which the experiments’ results would preoccupy the world 150 years later.
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. 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. And at the conference’s heart are the results of Tyndall’s experiments.
