构建低碳交通系统的必要性大量证据显示人类活动会导致全球气候变化。早在1986年,瑞典科学家Svante Arrhenius就提出人类活动产生排放的CO2会导致地球表面升温,并首次尝试量化了人类活动产生CO2浓度对地表温度的 The Need to Build a Low-Carbon Transportation System There is ample evidence that human activities can lead to global climate change. As early as 1986, Swedish scientist Svante Arrhenius proposed that human activities produce CO2 that causes warming of the Earth’s surface and for the first time attempts to quantify the effect of human activities on the production of CO2 at the surface temperature
