原文: But does this have anything to do with global warming, and are human emissions to blame? 译文：但这与全球气候变暖有关吗？人类的碳排放该指责谁呢？
【正确答案】：改译：但这与全球气候变暖有关吗？人类的碳排放是肇事之因吗？
【题目解析】：be to blame的意思是”应受谴责的，有过错的；是……起因或某事的根源的”。例如：My life is ruined and I suppose I only have myself to blame.（我的一生都毁了，我想这只能怪我自己。）You are not to blame; it is his fault. （这是他的错，不怨你。）
