The world needs to cut carbon emissions by nearly a fifth(将近五分之一) in the next four years, and by close to half(接近一半) within a decade, to avoid overshooting(超出（目标）) climate targets by a disastrous margin(以灾难性的幅度).
世界需要在未来四年内将碳排放削减近五分之一，并在十年内削减近一半，以避免气候目标被灾难性地突破。
Although the “window has closed” on holding temperature rises to 1.5C, in line with scientific advice, limiting the “overshoot” of that target is still possible, according to the UN Environment Programme (Unep).(尽管按照科学建议将升温控制在1.5°C以内的“窗口已经关闭”，但联合国环境规划署表示，仍有可能限制对该目标的“超调”。)

But countries are failing to translate their long-term targets on reducing emissions into short-term actions, a report on the “emissions gap” between climate goals and policies has found.(但一份关于气候目标与政策之间“排放差距”的报告发现，各国未能将长期减排目标转化为短期行动。)
