UN Secretary General Ban Ki-moon emphasized the importance of negotiators from 190 countries meeting in Bali to address climate change, stating they have a political and historical responsibility to reach an agreement. Ban expressed concern over the serious consequences of not reaching a deal, but believed all countries, including the United States, aimed to reach an agreement. Disagreements have arisen among countries like the United States, Japan, Canada, and Australia regarding guidelines for reducing greenhouse gas emissions. Despite this, Ban remained optimistic that an agreement would be reached during the summit in Bali. He cautioned against countries focusing too much on emission targets, stating that negotiations would need to happen in the future. Ban also mentioned that he was willing to return to Bali on Saturday if discussions remained at a standstill. He emphasized that negotiators, ministers, and senior leaders have a duty to successfully conclude the talks due to the political and historical significance. Ban stressed that climate change and global warming affect everyone, regardless of their nationality.
