出现 95% 的应该是这一段
Given the present composition of the atmosphere, the contribution to the total heating rate in the troposphere is around 5 percent from carbon dioxide and around 95 percent from water vapor.
但这段话还有下半句啊:
In the stratosphere, the contribution is about 80 percent from carbon dioxide and about 20 percent from water vapor.
这是因为,平流层向上,气温已经很低,空气相对干燥,水汽很小。这里主要吸收辐射的气体是二氧化碳和臭氧。
最重要的一句是:
It is important to remember, however, that it is currently believed that the impact of water vapor produced from surface sources such as fuel combustion on the atmospheric water vapor concentrations is minimal.
这样子,你的论点就不成立了。
