A NASA satellite orbiting over Portugal took photographs that reveal the effects of pollution from ships. One of the photos shows a thin film of clouds above the brilliant blue of the North Atlantic, cut by white lines of thicker clouds that look like scars. NASA officials explained those thicker clouds are signs of ship traffic below. When ships power their ways through the ocean, they pump exhaust into the atmosphere, just as cars do. And those massive amounts of particles can cause clouds to form. Get enough of those particles in one place, as from the exhaust of a ship, and they can lead to the creation of new clouds easily visible from space. "These clouds can be huge, some of them stretch hundreds of kilometers from end to end", NSAS officials said. It's likely that these sorts of clouds are having some effect on the global climate, according to NASA officials. But scientists aren't yet sure what effect it has.
葡萄牙上空運(yùn)行的一顆美航天局(NASA)衛(wèi)星拍攝的照片揭示了船舶污染的影響。其中一張照片顯示，蔚藍(lán)的北大西洋上空籠罩了一層薄云，間或還有更厚的云朵像疤痕一樣穿插其間。輪船開動(dòng)油門在海上行駛，也會(huì)向大氣中排放廢氣，與汽車一樣。排出的巨量微粒便會(huì)形成云朵。當(dāng)足夠多的尾氣微粒，就比如足夠多的輪船尾氣微粒積聚在一個(gè)地方，就會(huì)形成從太空都能輕松看見(jiàn)的云朵?！坝械姆浅４?，從一端到另一端的寬度足有數(shù)百千米，”NASA官員表示。據(jù)NASA官員稱，這些類型的云可能已經(jīng)對(duì)全球氣候產(chǎn)生一定影響。但具體是何種影響科學(xué)家們尚不確定。
