climate conference

Nearly 200 countries have delegates in Bonn, Germany, this week, trying to figure out how to fight global warming. They're at a difficult point — what the nations have pledged so far isn't enough.

Tiny island nations, Latin American developing countries and even non-joiners like Switzerland have all found more power and influence in climate negotiations after forming or joining a group.

It's a nightmarish job: No exercise or fresh air and little food and sleep for days at a time, all in an effort to persuade 200 countries to save Earth's climate and the planet. Can they do it?

Unlike the 1997 Kyoto treaty, the plan on the negotiating table in Lima this week asks every country, developed and developing, to limit carbon emissions. Each nation would set its own target.
