Commercial jets pumps out some 700 million tons of CO2 a year, about 2 percent of global emissions 1. That jet exhaut helps warm the planet, especially in the Arctic, which is especially unfortunate for future fliers because climate changes may screw up more turbulence 2 of the north Altantic, causing bumpier 3 flights there. That's according to a study in the Journal Major Climate Change. Researchers use climate stimulations to fast-forward to the year 2050. They find that the future climate data to the 21 turbulence predicting a, focusing on the type called clear-air turbulence, which literally 4 comes out the blue. Pilots can't spot it and neither can satellites through radar 5. The model forcasts by mid-century, clear-air turbulence would be more violent, and transatlantic flight will hit it twice as often, especially during the winter. Beyond spilling drinks, sever 6 clear-air turbulence can injure and kill passengers, and damage planes too-it once ripped out an engine of DC-8. The researcher say airlines may have to fly more detours 7 in the future to avoid it, a waste of time and fuel that ups emissions, which could be in higher ticket prices, and even less friendly skies.
