Delegates begin climate-change talks in Bangkok
Representatives from more than 160 countries began formal negotiations here Monday on a treaty to mitigate climate change, with the secretary general of the United Nations, Ban Ki Moon, urging governments to help in "saving the planet." The talks, which are scheduled to conclude at the end of 2009, come three months after a rancorous meeting in Indonesia that exposed deep fissures in how countries plan to battle global warming.
