Because black particles contain soot and absorb sunlight, they are believed to increase global warming. White particles, however, reflect some of the incoming sunlight back into space, producing a cooling effect on Earth’s climate.
因为黑色颗粒含烟尘并能吸收阳光，他们被认为会导致全球变暖增加。但白色颗粒能将射入的部分阳光反射回宇宙，因此对地球气候会产生冷却的效果。
