At that point, the part of the world’s population with advanced-country income levels ($20,000 dollars or above in today’s dollars) would increase from 16% to 66%. And, if the newly affluent follow the patterns of consumption, energy use, and carbon emissions that accompany high income levels now, the climate change battle will have been lost.
到那时，达到发达国家收入水平的世界人口（以美元现值计价为20，000美元或更多）将从16%增长到66%。但如果新崛起的富裕阶层效仿现在高收入者的消费、能源使用和碳排放模式，那么气候变化这场战役就失败了。
