A two-week-long series of UN climate-change talks in Bangkok attended by delegates from 180 countries ended on October 9, with their most notable result being a dispute between richer and poorer nations over whether to renew or abandon the Kyoto Protocol, the only existing global agreement that addresses so-called climate change. The next UN-sponsored climate talks will be held in Barcelona, which will be the last round of such talks before the summit in Copenhagen in December.
