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。

Beyond warming the atmosphere, black carbon can also speed the melting of glaciers by literally turning them black - soot on snow makes the ice heat up faster.

除了给大气加热，炭黑还能覆盖冰川表面，便其表面颜色变黑，从而加速冰川融化。
