1·It is important to note that other factors, such as volcanic particulates or variations in the amount of sunlight received by the Earth, could potentially have affected the climate.
必须指出的是，其他因素，如火山微粒或地球接收到的阳光量的变化，可能已经潜在地影响了气候。
2·As these rise, they latch on to dust in the air and become particulates, a quarter the size of a grain of sand.
上升过程中，这些元素附着在空气中的尘埃上，变成微粒，大小相当于一粒砂子的四分之一。
3·Emissions of greenhouse gases, carbon monoxide and particulates could all be significantly reduced.
温室气体、一氧化碳和微粒的排放全都可以显著降低。
4·Particulates can also melt the ice when they precipitate out of the air and land on it.
沉积到地面的大气微粒同样能融化冰川。
5·The authors said their research can be used to estimate the effect of total suspended particulates on other countries and time periods.
该项研究的作者还说，他们的研究可以用来估计总悬浮微粒对其他国家和时段的影响。
