这些颗粒物是人类生活活动产生的主要污染物，污染源也是人类大量开采地下煤和石油所造成的。
颗粒物分三部分降落，一部分较重一点的颗粒物升空不高就落地；还有一部分随雾霜落地；第三部分随水蒸气升空成云下雨或雪落地；颗粒物污染是一个非常严重的问题，全球不是变暖了，而是四季起变化了，变的该热的地方不热，该冷的地方不冷，太阳光的热量也不能完全照射到地面。
科研考查说了 北冰山在容化 别以为今年冬天冷 还不是北冰山的冷空气向我们这里吹 不过全球暖化很好啊 动植物开始可以加种繁殖了 成为绿色家园 就不愁喝不咖啡了 哈哈
冬天雪厚是因为在大气中遇到强对流,云层超负荷,所以降下大雪,而遇到的这强对流就是因为全球变暖所引起的.再有只要积雨云有水,地面温度达到零下摄氏度就有可能降雪.

An already relentless melting of the Arctic greatly accelerated this summer, a warning sign that some scientists worry could mean global warming has passed an ominous tipping point. One even speculated that summer sea ice would be gone in five years.
Greenland's ice sheet melted nearly 19 billion tons more than the previous high mark, and the volume of Arctic sea ice at summer's end was half what it was just four years earlier, according to new NASA satellite data obtained by The Associated Press.
