因为大气碳含量增加表现在气候变化上要经过几年的时间，把它限制在450 ppm的水平上需要我们现在就终止排放。
Because the effects of atmospheric carbon take years to show up as higher temperatures, limiting concentration to 450 ppm requires halting emissions at current levels.
多数人以为只要排放的速度不增加就能终止大气中二氧化碳水平的上升，犹如水笼头的水稳定而快速的流入不会最终溢出浴缸。
Most thought that simply stopping emissions from rising would stop the rise of CO2; in the atmosphere - as if a tap running steadily but rapidly would not eventually overflow the tub.
