This year will offer one more critical opportunity to reestablish hard legality in international negotiations: the United Nations Climate Change Conference in Paris in December. It is widely believed that the conference may well represent the world’s last chance to limit the global temperature increase to 2º Celsius over pre-industrial levels – the threshold beyond which the risks of climate change become particularly daunting.
今年还将提供另一个在国际谈判中重建硬法律性的关键机会：12月的巴黎联合国气候变化会议。人们广泛认为，这次会议将是世界最后的机会把全球气温升高幅度限制在前工业化水平以上2℃之内——超过这一阈值，气候变化风险就会显著提高。
