WARMER WORLD
Jets’ Fringe Benefit (Special Crapdt. N.Z.P.AJ LONDON, June 20. The exhausts of supersonic airliners may bring warmer weather to the world by spreading a layer of water vapour and carbon dioxide in the stratosphere, thus trapping the heat. According to an American geophysicist ProfesSor G. MacDonald, of the University of California, surface temperatures by 1980 will rise by 0.4 degrees Fahrenheit if 400 supersonic airliners make four flights a day on intercontinental routes.
The airliners, flying at 50,000 to 60,000 feet, would spew 150,000 tons of water vapour a day into the stratosphere. Carbon dioxide would also be discharged in big quantities and this would appreciably affect the concentration in the stratosphere. Some of the heat normally lost by the earth would be trapped because it is radiated at wave-lengths absorbed by carbon dioxide and water vapour. According to Professor MacDonald, the temperature in the stratospheric layer could rise 4 or 5 deg.
