Global Warming Alarmists Claim Airplanes Won’t Fly in 50 Years

Airplanes of the future will have to carry lighter loads more often thanks to global warming, according to two scientists at Columbia University, New York. They reached their conclusion by creating models which predicted that by 2060 there will be more warm days but no commensurate technological advances in the aviation industry. The two scientists, Coffel and Horton, looked at a phenomenon known amongst pilots as ‘density altitude’, which affects a plane’s ability to take off. Essentially, on hotter days the air is less dense, making it harder to get a plane airborne. It is a particular problem at airports with short runways, as the planes will take longer to lift off. Commercial aviation overcomes the problem by issuing weight restrictions at the airport on particularly hot days. Coffel and Horton sought to predict how many more weight restricted days there will be by 2050-2070, and decided, through use of models, that the "number of weight restriction days between May and September will increase by 50-200 percent at four major airports in the United States by 2050-2070," and that "these performance reductions may have a negative economic effect on the airline industry."...more
