ENN News Story - Pollution may act as antifreeze in high clouds: "Those wispy cirrus clouds that float high in the sky may be thinning out due to nitric acid pollution, a change that scientists say could affect climate.
Airborne measurements of the high clouds taken in the summer of 2002 showed increased humidity in the clouds and found nitric oxide, which is a pollutant that comes from jet exhaust, combustion on the ground, and other sources, according to a paper in Friday's issue of the journal Science."
