scars.[1]NASA officials explained those thicker clouds are signs of ship traffic below.When ships power their waythrough 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 kilometres from end to end，”NASA officials said.[2]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.
