摘要

Concerns about global warming are focusing increasingly on the contribution of human activities, including aviation. Jet aircraft are among many sources of greenhouse gases, gases that can trap heat, potentially increasing the temperature of the earth's surface and leading to changes in climate. Our report focuses on the effects of subsonic jet aircraft engine emissions on the upper atmosphere (above 3,000 feet) and does not address the effects of these emissions on local air quality. A recent international review of aviation and the global atmosphere had a similar focus. We focused on commercial civilian subsonic jet aircraft because they account for the majority of aviation emissions; military and general aviation aircraft account for the remainder. In the commercial fleet, fewer than 15 civilian supersonic jets currently operate worldwide.
