Longer Airline Flights Proposed to Combat Global Warming: "Tendrils of condensation that mark the paths of high-flying jets sometimes form a loose lacework of man-made clouds in the upper atmosphere. The extra blanket of atmospheric insulation from these spreading contrails, as they are called, could accelerate global warming, studies have shown.
Now a group of researchers says something should be done. Their proposal would lengthen the typical airline flight."
