26. 1991 年 6 月 15 日，菲律宾吕宋岛上的皮纳图博火山突然大喷发，2000 万吨二氧化硫气 体冲入平流层，形成的霾像毯子一样盖在地球上空，把部分要照射到地球的阳光反射回太空。 几年之后，气象学家发现这层使得当时地球表面的温度累计下降了 0.5℃ .而皮纳图博火山 喷发前的一个世纪，因人类活动而造成的温度效应已经使地球表面温度升高 1℃。某位持“人 工气候改造论”的科学家据此认为，可以用火箭弹等方式将二氧化硫充入大气层，阻挡部分 阳光，达到地球表面降温的目的。

以下哪项如果为真，最能对该科学家提议的有效性构成质疑？

(A)如果利用火箭弹将二氧化硫充入大气层，会导致航空乘客呼吸不适。 (B)如果在大气层上空放置反光物，就可以避免地球表面强烈阳光的照射。 (C)可以把大气中的碳取出来存储到地下，减少大气层的碳含量。 (D)不论何种方式，“人工气候改造”都将破坏地球的大气层结构。 (E)火山喷发形成的降温效应只是暂时的，经过一段时间温度将再次回升
