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
根据前文可以看出来， “啥啥啥 are the most obvious effects”应该是气象学家给出的一个答案，因此the most obvious effects一定是出现在主句中的，而不能做修饰成分，排除DE，BC有明显错误，选a
