Radioactive forcing is defined as "the change in the energy balance of the lower atmosphere by a climate change mechanism" and is measured in units of Watts per square metre (W/m2). The radiative forcing of emissions from aeroplanes are how much higher than the radiative forcing of CO2 alone?
答案是多少呢?各位大虾们?
下面有几个选项
1.9 2.3 3.5 3.9

翻译:

辐射强迫的定义是“变化中的能量平衡的低层大气中的气候变化机制” ,是衡量单位的瓦每平方米( W/m2 ) 。辐射强迫的排放量从飞机是如何远远高于辐射强迫的二氧化碳呢?
