GWD-24-Q 23

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.

A.    the most obvious effects, and those that would have the largest
            impact on people, would be extremes of temperature,
            precipitation, and storminess

B.    the effects that are the most obvious ones, extremes of temperature, precipitation, and storminess, would be those impacting
            the most on people

C.    those effects to have the largest impact on people, extremes of
            temperature, precipitation, and storminess, are what are the most obvious effects

D.    extremes of temperature, precipitation, and storminess, the most
            obvious effects, that they would have the largest impact on people

E.     extremes of temperature, precipitation, and storminess, which are
            the most obvious effects, are those to impact the most on people
