An article in a magazine denies that Earth is warming and climate change is occurring. The writer reports that this season was the snowiest winter on record for the Northeast, with lower than average temperatures for the region. Because of the low temperatures, the writer concludes that climate change cannot possibly be occurring. What question should you ask the writer to clarify whether his stance on climate change is scientifically sound?
(A) Did the snowstorms cause extensive damage?
(B) Was this the coldest month on record for this region?
(C) Were the snowfall totals of each storm larger or smaller than last year?
(D) Were long-term temperature changes investigated in addition to short-term change?
