Last September, the Intergovernmental Panel for Climate Change warned that if the world sticks with “business as usual,” global temperatures may rise more than 4°C – far beyond the 2°C increase that has been deemed “safe.” This prompted UN Secretary-General Ban Ki-moon to challenge political, economic, and financial leaders in January to intensify their efforts to achieve a new global agreement on climate change by 2015.
去年9月，联合国政府间气候变化专门委员会（Intergovernmental Panel for Climate Change）警告说，如果世界再不转变增长模式，全球气温将升高4—6℃，远远超出被认为是“安全”的2℃升温水平。这促使联合国秘书长潘基文在今年1月敦促政治、经济和金融各界领导人加紧努力，争取在2015年达成新的全球气候变化协议。
