Abstract: The World Wide Fund for Nature has released a report drawing attention to pollution caused by airplanes. Aircraft give off the same harmful gases emitted by cars, mainly carbon dioxide and nitrogen oxides, but the effect is magnified many times over because of the thinness of the air at high altitudes. Nitrogen oxides emitted at high altitudes produce high-level ozone, which traps heat and contributes to global warming. Closer to the ground, these gases can be washed out by rain, but at higher altitudes they collect in the atmosphere.
