单项选择题

阅读下文,完成以下问题。

美国华盛顿大学研究人员在《科学》杂志上发表报告说,尽管人类活动对于气温的全国上升确实起了作用,但是这种气候变化绝大部分要归咎于自然原因。他们对北半球近一个世纪以来的温度变化所作详细研究的结果表明,联合国和其他国际组织近来在一些报告中对全球气候变暖原因的解释是靠不住的。

报告的主要作者,担任华盛顿大学、国家海洋和大气管理局大气和海洋联合研究所所长的约翰·华莱士说:“我们所作的研究已经清楚地表明全球气候的不断变化,是怎样引起气候的短期变动的。反过来,这种变动又有助于我们更好地了解大气层的温室效应(大部分是由于燃烧矿物燃料产生的二氧化碳引起的)可能引起的气候变暖的程度。”他告诫道,不能因为这个结果而放松对人类破坏环境行为的注意。

这些气象学家说,从1975年至1990年间,北半球冬季气温(特别是美国的阿拉斯加、加拿大北部和俄罗斯等地)上升了0.3℃。他们认为这一气温上升有1/3是由大气环流的自然变动引起的。他们还认为,北半球地区从1900年至1990年近一个世纪以来的月温差约有一半也是由这种变动引起的。

华莱士说:“尽管人类活动与气温的全面上升可能也有关系,但是我们认为,这种气候变化绝大部分应归因于自然变动,与温室效应引起的气候变暖无关。由于地表吸收热量的能力(热容量)比海洋低得多,地表冬季和夏季的温差非常大。 因此, 当大气环流带动暖气团吹过北半球各大陆以及冷气团吹过海洋上空时,北半球的平均气温往往比较暖和。”他说,尽管科学家们尚不完全了解引起大气环流型式变化的真正原因,但他确信这与自然变化有关。

第二段中,华莱十所说的“这种变动”指的是()。

A.暖气团、冷气团吹过大陆和海洋所造成的气温变化。

B.若干年间气温上升幅度或月温差的变化。

C.温室效应引起的不同程度上的气温变化。

D.对全球气候之所以变暖的认识上的变化。
