Carbon dioxide, in his view, is the main culprit. Black carbon deposited on the Arctic snow and ice, he says, will have only a minimal effect on its reflectivity.

他认为二氧化碳是主要的“凶手”，而北冰洋雪和冰上聚集的黑碳对反射作用的影响很小。

But the pollutant also ACTS to reduce the reflectivity of ice and snow, allowing heat absorption and hastening surface melt.

然而，这种污染物却能够降低冰雪的反射率，增加热量的吸收，加快其表面的融化。
