Two weeks of international talks aimed at limiting global warming have made progress, and more can be done at a more important meeting at the end of the year in Cancun, Mexico, the U.N. climate-change chief said Friday in Bonn, Germany. "A big step forward is now possible at Cancun, in the form of a full package of operational measures that will allow countries to take faster, stronger action across all areas of climate change," said Yvo de Boer, the executive secretary of the U.N. Framework Convention on Climate Change. Progress was made on the negotiating documents and on how to turn national non-binding commitments by many countries into part of the talks, de Boer-who is leaving his post at the end of the month-explained Friday, the last day of the negotiation in Bonn. Another major conference to work toward an international accord limiting global warming will be held in December in Cancun after last year's Copenhagen conference failed to deliver a strong binding agreement to replace the 1997 Kyoto Protocol, which expires in 2012.
