Kyoto climate deal hopes grow
BONN,Germany (CNN) -- Hopes are being expressed at a climate summit in Bonn that the Kyoto Protocol can be implemented without the U.S. on board.
Environment ministers and representatives from 178 countries are on Thursday opening negotiations on how to resolve remaining disputes over the 1997 treaty.
Jan Pronk, the Dutch environment minister and conference chairman, said he was "optimistic" a deal could be reached to bring a global warming agreement into effect.

"It is possible to reach a result," Pronk said. "My hopes are growing day by day."

He said: "We believe that we ought to all work together to reduce greenhouse gases. Howe
