The global climate is more than likely to slip into an unpredictable state with unknown consequences for humansocieties if carbon dioxide emissions continue on their present course, a survey of leading climate scientists has found.
一项对知名气候科学家的调查发现，如果二氧化碳排放继续保持目前的进程，全球气候完全有可能陷入不可预料的状态，并给人类社会带来未知的后果。
The 14 scientists, all experts in their fields of climate research, were asked about the probability of a tipping point being reached some time before 2200 if global warming continued on the course of the worst-case scenarios predicted by the Intergovernmental Panel on Climate Change (IPCC).
这14名科学家都是各自所在气候领域中的专家。他们被问到，如果全球变暖继续按照政府间气候变化问题研究小组(IPCC)所预言的最糟糕的情形发展，那么在2200年之前的某个时候出现“拐点”(气候系统的根本改变)的概率有多大。
