  All of the experts agree that in the coming century we are likely to witness an increase in global average temperatures not experienced in the past 10,000 years. However, a tipping point is a more qualitative change to the way the climate system behaves, Dr Allen said.

  所有专家一致认为,下一个世纪我们很可能目睹全球平均气温的上升,这种上升是过去1万年中从未有过的。不过艾伦表示,“拐点”更多地是气候系统表现方式的质变。

  The increase in carbon dioxide emissions over the coming few decades will be crucial in determining the sort of climate that the world will live in by the year 2200. Current CO2 levels, running at about 380 parts per million (ppm), are likely to rise to 1,000 ppm if nothing is done to curb emissions from the burning of fossil fuels suchas oil and coal.

  今后几十年里二氧化碳排放的增加,对于确定世界到2200年时所处的气候类型具有至关重要的影响。如果不采取任何行动限制燃烧石油和煤炭等矿物所产生的排放,那么目前的二氧化碳浓度水平--- 大约是380ppm(ppm为百万分之一)--- 很可能上升到1000ppm
