    Contrail cirrus radiative forcing for future air traffic

    A scientific study projects that contrail cirrus (cloud formations created by aircraft exhaust) will produce three times more climate warming by 2050 compared to 2006, driven largely by a fourfold increase in air traffic volume. While reducing soot emissions from aircraft by 50% could cut this warming effect by about 15%, the researchers found that fuel and emissions improvements alone cannot offset the dramatic rise in contrails expected from increased flight activity. The study focuses on global climate impacts rather than local airport noise, and may have limited direct relevance to Sea-Tac Airport noise policy.
