Consider black carbon, a component of the soot emissions from diesel engines and the inefficient burning of biomass cooking stoves that is linked to 1.6 million to 1.8 million premature deaths annually as a result of indoor exposure and 800,000 as a result of outdoor exposure. Black carbon, which absorbs heat from the sun, also accounts for anywhere from 10% to more than 45% of the contribution to global warming, and is also linked to accelerated losses of glaciers in Asia, because the soot deposits darken, ice making it more vulnerable to melting.
比如说炭黑，这种来源于柴油机废气以及家庭煮食燃料不充分燃烧的物质每年都导致160~180万宗室内死亡案例和80万宗室外死亡案例。而这种从阳光中吸收热量的物质同时也与10%~45%的全球变暖效应有关，并导致了亚洲地区的冰川加速融化，因为这些沉积物的逐渐堆积使冰变得更黑，也更容易融化。
