Moreover, negotiators will not get another chance. After more than two decades of largely fruitless debate, during which CO2 emissions have continued to rise, another failed summit will trigger a profound crisis for international climate diplomacy, forcing its proponents either to change the rules of the game or accept that it cannot be won.
此外，谈判各方不再会有另一次机会。在经历了20多年几无成果的争论后——在此期间二氧化碳排放量节节升高——又一次失败的峰会将触发深远的国际气候外交危机，其支持者要么修改游戏规则，要么接受不可能赢的现实。
