This time will not be different. While an agreement might be reached in 2015, it will probably not cover all major emitters, and it definitely will not be ambitious enough to achieve the overarching goal of international climate cooperation, which is to prevent global temperatures from rising more than 2° Celsius above pre-industrial levels.
这次也不会不同。尽管2015年可能达成协定，但或许不会覆盖所有排放国，力度肯定不足以实现国际气候合作的全面目标——防止全球气温在前工业化水平的基础上升高2℃以上。
