判断题 It is dangerous for people to live on the Earth if CO2 concentrations continue to rise.（）
对
错
正确答案：对
答案解析: 该段录音中指出“最近趋势显示二氧化碳的排放量正在超过大自然的吸收能力”，过去几年空气中二氧化碳含量的增速突然上升到2.54ppm或以上，这意味着自然系统减少碳排放量的能力正在减弱。可推测，如果二氧化碳浓度持续升高，居住在地球上将会是危险的。
【录音原文】Recent trends suggest that carbon emissions are outpacing absorption.Over the past two decades, atmospheric CO2 concentrations rose each year, on average, by 1.5 parts per million(ppm) , but the last few years have seen unexplained and alarming jumps of up to 2.54ppm and beyond.This suggests that the ability of the Earth’s natural systems to mitigate the rise in carbon emissions is weakening.
