Discussion of greenhouse effects has usually focused on whether the Earth would warm and by how much, but climatologists have indicated all along that the most obvious effects, and those that would have the largest impact on people, would be extremes of temperature, precipitation, and storminess.
the most obvious effects, and those that would have the largest impact on people, would be extremes of temperature, precipitation, and storminess
the effects that are the most obvious ones, extremes of temperature, precipitation, and storminess, would be those impacting the most on people
those effects to have the largest impact on people, extremes of temperature, precipitation, and storminess, are what are the most obvious effects
extremes of temperature, precipitation, and storminess, the most obvious effects, that they would have the largest impact on people
extremes of temperature, precipitation, and storminess, which are the most obvious effects, are those to impact the most on people
题意：关于温室效应的讨论通常集中在【地球是否会变暖以及变暖的程度上】，但气候学家一直指出，最明显的、对人类影响最大的影响是【极端的温度、降水和暴风雨】。
A&E:
第一个分析：
1。 which 指代不明：根据句意， which 应该指代extremes of temperature, precipitation, and storminess，但是在 E 中，which 只能指代 storminess；
2。 to impact the most on people 表达有问题，既不应该用表目的的to do，impact ... on 也不地道。
3。 主宾倒置，强调的中心完全变了。（这个是重点核心，比较对象变了！）
第二个分析：
A项：关于温室效应的讨论集中在...,但是气象学家指出最明显的效应是…
E项，关于温室效应的讨论集中在...,但是气象学家指出...是影响人们最大的。
很明显，A为正确选项。因为A紧紧围绕关于温室效应的讨论，用but来对比。而E项，but后的气象学家指出的东西与前面的不是一个问题。所以如果选E项，but就没有道理存在。
