Airplane passengers are in for an increasingly bumpy ride according to a study released today in the journal Advances in Atmospheric Sciences. Climate change is altering the jet stream, making severe turbulence more likely. The study builds on earlier work which found that climate change would lead to bumpier airplane rides. What makes the new research unique is that it quantifies how much different kinds of turbulence will increase—59 percent in the case of light turbulence, a 94 percent increase in moderate turbulence, and 149 percent increase in severe turbulence.
