A more recent report from NASA documented a 1 percent per decade increase in cirrus cloud cover over the United States, presumably due to increased air travel. (livescience.com)

Chemically, there will be an increase in ozone depletion (due to increases in heterogenous surface chemistry in the stratosphere), increases in acid rain, possibly an increase in high cirrus cloud cover due to indirect effects of the sulphates on cloud lifetime. (treehugger.com)
